  • Self-reported jumpers’ knee is common in elite basketball athletes –
           But is it all patellar tendinopathy'
    • Abstract: Publication date: Available online 23 January 2020Source: Physical Therapy in SportAuthor(s): Madeline Hannington, Sean Docking, Jill Cook, Suzi Edwards, Ebonie RioAbstractObjectivesTo describe the prevalence and pain location of self-reported patellar tendinopathy and abnormality in a male elite basketball population.DesignCross-sectional.SettingPre-season basketball tournament.ParticipantsSixty male athletes from the Australian National Basketball League.Main outcome measuresSelf-reported patellar tendinopathy (PT) using the Oslo Sports Trauma Research Centre Overuse Questionnaire (OSTRC). Pain location using pain mapping (dichotomised: focal/diffuse) and severity during the single leg decline squat. Ultrasound tissue characterisation scans of both patellar tendons.ResultsThirteen participants (22.7%) self-reported PT. Only 3 who reported PT had localised inferior pole pain. Of the 30 (50.0%) with pain during the decline squat, 15 described focal pain and 10 diffuse pain (5 missing data). Those with diffuse pain had greater years played [Md = 21 (13–24), n = 10 than focal pain (Md = 12 (7–26), n = 15), p = 0.042, r = 0.3]. Bilateral tendon abnormality was found in 45% of athletes and 15% had unilateral tendon abnormality.ConclusionElite male basketball athletes self-reporting PT had heterogeneity in pain location. When focal pain with loading was used as a primary definition of PT, ‘jumpers’ knee’ was not common in this cohort. This study found that abnormality of the patellar tendon was common and did not correlate with symptoms.
  • Hip muscle strength asymmetries and their associations with hip morphology
           and symptoms are sex-specific in patients with femoroacetabular
           impingement syndrome
    • Abstract: Publication date: Available online 21 January 2020Source: Physical Therapy in SportAuthor(s): Nicola A. Maffiuletti, Mario Bizzini, Reto Sutter, Christian W. Pfirrmann, Florian D. Naal, Michael Leunig, Nicola C. CasartelliAbstractObjectivesTo investigate sex-specific differences in hip muscle strength asymmetries, and associations between hip abductor and flexor strength asymmetries, hip morphology and symptoms in patients with femoroacetabular impingement syndrome (FAIS).DesignCross-sectional study.SettingClinical setting.ParticipantsThirty-four patients with FAIS (21 women, 13 men).Main outcome measuresSide-to-side strength asymmetries of hip adductor, abductor, internal and external rotator, flexor and extensor muscles were assessed using dynamometry, while hip pain during contractions was evaluated with a visual analogue scale. Hip morphology was assessed on anteroposterior pelvic radiographs and magnetic resonance arthrography images. Hip symptoms were evaluated using the Oxford Hip Score (OHS).ResultsWomen presented larger hip flexor strength asymmetries than men. In women, hip abductor asymmetries correlated with the OHS and with hip pain during muscle contraction. Hip flexor asymmetries correlated with the alpha angle in men.ConclusionPatients with FAIS demonstrated sex-specific hip muscle strength asymmetries and associations with the underlying hip symptoms and morphology. Women showed larger hip flexor strength asymmetries than men, and their hip abductor strength asymmetries were associated with hip symptoms. In contrast, hip flexor strength asymmetries in men were associated with the severity of the underlying cam morphology.
  • The effects of midfoot strike gait retraining on impact loading and joint
    • Abstract: Publication date: Available online 21 January 2020Source: Physical Therapy in SportAuthor(s): Zoe Y.S. Chan, Janet H. Zhang, Reed Ferber, Gary Shum, Roy T.H. CheungAbstractObjectiveTo assess the biomechanical changes following a systematic gait retraining to modify footstrike patterns from rearfoot strike (RFS) to midfoot strike (MFS).DesignPre-post interventional study. All participants underwent a gait retraining program designed to modify footstrike pattern to MFS. Setting: Research laboratory.ParticipantsTwenty habitual RFS male runners participated.Main outcome measuresGait evaluations were conducted before and after the training. Footstrike pattern, loading rate (LR), ankle and knee joint stiffness were compared.ResultsParticipants' footstrike angle was reduced (p  0.155). Further subgroup analyses were conducted on the respondents (n = 8, 40% of participants) who exhibited MFS for over 80% of their footfalls during the post-training evaluation. Apart from the increased knee joint stiffness (p = 0.005, Cohen's d = 1.14), respondents exhibited a significant reduction in the ankle joint stiffness (p = 0.019, Cohen's d = 1.17) when running with MFS.ConclusionsGait retraining to promote MFS was effective in reducing runners’ footstrike angle, but only 40% of participants responded to this training program. The inconsistent training effect on impact loading suggests a need to develop new training protocols in an effort to prevent running injuries.

  • Effects of a foot strengthening program on foot muscle morphology and
           running mechanics: A proof-of-concept, single-blind randomized controlled
    • Abstract: Publication date: Available online 13 January 2020Source: Physical Therapy in SportAuthor(s): Ulisses T. Taddei, Alessandra B. Matias, Fernanda I.A. Ribeiro, Sicco A. Bus, Isabel C.N. SaccoAbstractObjectivesTo investigate the effects of a foot training program on muscle morphology and strength as well as running biomechanics in healthy recreational runners.DesignProof-of-concept, single-blind randomized controlled trial.SettingsRunners were allocated to a control (CG) or an intervention (IG) group. The intervention focused on strengthening the intrinsic foot muscles and their activation during weight-bearing activities. All participants were assessed at baseline and after 8-weeks.ParticipantsTwenty-eight healthy recreational long-distance runners not habituated to minimalist running shoes or barefoot running.Main outcomes measuresOutcomes were hallux and toes strength; foot function, cross-sectional area and volume of the abductor hallucis (ABH), abductor digiti minimi (ABV), flexor digitorum brevis (FDB), and flexor hallucis brevis; medial longitudinal arch range of motion and stiffness; vertical and antero-posterior propulsive impulses during running.ResultsCompared to the CG, an increase was found in the IG for the volume of all muscles investigated and for vertical propulsive impulse during running. Correlations were found between vertical propulsive impulse and volume of ABH(r = 0.40), ABV(r = 0.41), and FDB(r = 0.69).ConclusionThe foot exercise protocol effectively increased intrinsic foot muscle volume and propulsive forces in recreational runners. This shows that intrinsic muscle strengthening affects running mechanics and suggests that it may improve running performance.
  • Effects of low-level laser therapy on hamstring strain injury
           rehabilitation: A randomized controlled trial
    • Abstract: Publication date: Available online 10 January 2020Source: Physical Therapy in SportAuthor(s): Diulian Muniz Medeiros, Mateus Aimi, Marco Aurélio Vaz, Bruno Manfredini BaroniAbstractObjectivesTo evaluate the effects of low-level laser therapy (LLLT) on functional rehabilitation following hamstring strain injury (HSI) in amateur athletes treated with an exercise-based rehabilitation program.DesignRandomized controlled trial.MethodsMale athletes (18–40 years old) who sustained HSI were randomized in LLLT or placebo groups. All patients were engaged in the same exercise-based rehabilitation program until they met specific criteria to return to sport. Hamstring muscles were treated with LLLT or placebo immediately after each rehabilitation session. The primary outcome was time-to-return to sport. Secondary outcomes were the number of rehabilitation sessions, hamstring flexibility, hamstring strength, and re-injury rate.ResultsTwenty-four athletes began rehabilitation, and 22 (11 per group) completed the study schedule. Participants of LLLT and placebo groups had similar age, body size, injury characteristics, and baseline levels of hamstring flexibility and strength. The two groups increased flexibility and strength similarly along the rehabilitation program. Time-to-return to sport was the same for athletes treated with LLLT (23 ± 9 days) and placebo (24 ± 13 days). There were no re-injuries within 6 months after return to sport.ConclusionLLLT, as used in this study, did not optimize functional rehabilitation following HSI in amateur athletes treated with an exercise-based rehabilitation program.
  • Measurement Properties of Hip Strength Measured by Handheld Dynamometry:
           Reliability and Validity Across the Range of Motion
    • Abstract: Publication date: Available online 10 January 2020Source: Physical Therapy in SportAuthor(s): David M. Bazett-Jones, Kaitlin SquierAbstractObjectivesDifferent angles and positions may influence the reliability and validity of hip strength dynamometry. This study examined the reliability and validity of hip strength measured with belt-stabilized handheld dynamometry (HHD) compared to isokinetic dynamometry (IKD) across multiple angles.DesignRepeated measures.SettingBiomechanics laboratory.ParticipantsThirty healthy participants completed 3 sessions.Main Outcome MeasuresHip torque was measured for hip abduction (ABD; -10°, 0°, 20°, and 40°), internal rotation (IR; -30°, -15°, 0°, 15°, and 30°), external rotation (ER; -30°, -15°, 0°, 15°, and 30°), and extension (EXT; -10°, 0°, 30°, 60°, 90°, and 120°).ResultsABD was reliable (no intratester reliability differences p=0.409-0.997; ICC=0.624-0.900) and valid (no HHD-IKD difference p=0.270-0.946; r=0.556-0.624) measure. IR had questionable reliability (intratester reliability differences p=0.001-0.043; ICC=0.682-0.879) and validity (HHD-IKD differences p
  • Cognitive-behavioral-based physical therapy to enhance return to sport
           after anterior cruciate ligament reconstruction: An open pilot study
    • Abstract: Publication date: Available online 9 January 2020Source: Physical Therapy in SportAuthor(s): Rogelio A. Coronado, Emma K. Sterling, Dana E. Fenster, Mackenzie L. Bird, Allan J. Heritage, Vickie L. Woosley, Alda M. Burston, Abigail L. Henry, Laura J. Huston, Susan W. Vanston, Charles L. Cox, Jaron P. Sullivan, Stephen T. Wegener, Kurt P. Spindler, Kristin R. ArcherAbstractObjectivesTo describe feasibility, adherence, acceptability, and outcomes of a cognitive-behavioral-based physical therapy (CBPT-ACLR) intervention for improving postoperative recovery after anterior cruciate ligament reconstruction (ACLR).DesignPilot study.SettingAcademic medical center.ParticipantsEight patients (mean age [SD] = 20.1 [2.6] years, 6 females) participated in a 7-session telephone-based CBPT-ACLR intervention beginning preoperatively and lasting 8 weeks after surgery.Main outcome measuresAt 6 months, patients completed Knee Injury and Osteoarthritis Outcome Score (KOOS) sports/recreation and quality of life (QOL) subscales, International Knee Documentation Committee (IKDC), Tampa Scale of Kinesiophobia (TSK), Pain Catastrophizing Scale (PCS), and Knee Self-Efficacy Scale (K-SES), return to sport (Subjective Patient Outcome for Return to Sports), and satisfaction. Minimal clinically important difference (MCID) was used for meaningful change.ResultsSeven (88%) patients completed all sessions. Seven (88%) patients exceeded MCID on the TSK, 6 (75%) on the PCS, 5 (63%) on the KOOS sports/recreation subscale, 4 (50%) on the IKDC, and 3 (38%) on the KOOS QOL subscale. Three (38%) patients returned to their same sport at the same level of effort and performance. All patients were satisfied with their recovery.ConclusionsA CBPT-ACLR program is feasible and acceptable for addressing psychological risk factors after ACLR.
  • Vibration increases multifidus cross-sectional area versus cryotherapy
    • Abstract: Publication date: Available online 7 January 2020Source: Physical Therapy in SportAuthor(s): Carlos Romero-Morales, Pedro Javier Martín-Llantino, César Calvo-Lobo, Marta San Antolín-Gil, Daniel López-López, María Benito-de Pedro, David Rodríguez SanzObjectiveTo assess multifidus muscle thickness, cross-sectional area (CSA) and disability in patients with chronic non-insertional Achilles tendinopathy (AT) who developed an eccentric exercise (EE) vibration program compared to an EE program with cryotherapy.DesignSingle-blinded randomized clinical trial.SettingOutpatient clinic.ParticipantsA total sample of 61 patients diagnosed with chronic non-insertional AT was recruited and randomly divided into two groups. A group (n = 30) developed the EE program plus vibration and B group (n = 31) received the EE program plus cryotherapy for 12 weeks. Multifidus thickness and CSA were measured at rest and during maximal isometric contraction by ultrasound imaging. The Victorian Institute for Sport Assessment (VISA-A) was used to asses functionality.ResultsMultifidus CSA was statistically significant increased (P 
  • Female adolescents demonstrate greater oculomotor and vestibular
           dysfunction than male adolescents following concussion
    • Abstract: Publication date: Available online 7 January 2020Source: Physical Therapy in SportAuthor(s): Margot Gray, Julie Wilson, Morgan Potter, Aaron Provance, David HowellAbstractObjectiveTo examine differences between male and female adolescents on measures of balance, vestibular and oculomotor function within 3 weeks of concussion among a group of pediatric patients presenting to a sports medicine clinic.DesignMedical record review.SettingSports medicine clinic.Participants197 female (median age=15.2 years) and 381 male (median age=14.6 years) pediatric patients seen for a concussion, evaluated 9.3±5.2 (mean±SD) days post-concussionMain Outcome MeasuresPatients completed Balance Error Scoring System (BESS), tandem gait, gaze stability, and near point of convergence (NPC) tests.ResultsA higher proportion of female patients exhibited abnormal NPC (22% vs. 14%; p=0.017), gaze stability (53% vs. 43%; p=0.028), and tandem gait tests (20% vs. 13%; p=0.026) compared to male patients. Multivariable analysis indicated an independent association between female sex and increased odds of abnormal NPC (adjusted odds ratio [aOR]=1.79, 95% CI=1.07-3.00), and tandem gait tests (aOR=1.96, 95% CI=1.12-3.41) following concussion.ConclusionsOur results indicate that within the first three weeks of a concussion, female pediatric patients demonstrated increased odds of exhibiting abnormal near point of convergence, and tandem gait test performance compared to male patients.
  • Comparison of shoulder range of motion, strength, and upper quarter
           dynamic balance between NCAA division I overhead athletes with and without
           a history of shoulder injury
    • Abstract: Publication date: March 2020Source: Physical Therapy in Sport, Volume 42Author(s): Youngwook Kim, Jung-Min Lee, Elizabeth Wellsandt, Adam B. RosenAbstractObjectiveTo determine differences in shoulder range of motion, strength, and upper quarter dynamic balance between collegiate overhead athletes with and without a history of a shoulder injury.DesignCross-sectional study.SettingAthletic training clinic.Participants58 overhead athletes who were fully participating in NCAA Division I overhead sports (baseball, softball, volleyball, and tennis) and free of any current shoulder injury were included. Participants were divided into a shoulder injury history group (n = 25) and uninjured group (n = 33). Participants in the shoulder injury history group had a previously resolved shoulder injury.Main outcome measuresActive range of motion assessments for shoulder internal rotation, external rotation, and horizontal adduction. Isometric strength assessments for shoulder IR and ER. The Upper Quarter Y-Balance Test.ResultsThe shoulder injury history group demonstrated a lower Upper Quarter Y-Balance Test mean score in the superolateral direction (p = .03, d = 0.56), but no group differences existed for other results (p > .05).ConclusionsOverhead athletes with a history of shoulder injury had worse upper quarter dynamic balance versus those without the history. From a clinical perspective, the findings may have significant implications for developing shoulder re-injury prevention and rehabilitation protocols in relation to their shoulder injury history.
  • Concurrent validity of two-dimensional video analysis of lower-extremity
           frontal plane of movement during multidirectional single-leg landing
    • Abstract: Publication date: March 2020Source: Physical Therapy in Sport, Volume 42Author(s): Ahmed Alahmari, Lee Herrington, Richard JonesAbstractObjectivesEstablish the concurrent validity between 2D video analysis and 3D motion analysis of frontal plane lower limb movements during multidirectional landing tasks.DesignCorrelation study.SettingUniversity Biomechanics laboratory.Participants34 (19 male, 15 female) uninjured physical active individuals.Main outcome measuresknee abduction and hip adduction angles during a variety of single leg landing tasks.Results2D knee abduction showed an association with 3D knee abduction angle ranging from r = 0.17–0.42 across the tasks, with r2 values ranging between 0.03 and 0.17. 2D hip adduction angle in both legs reported a strong and significant correlation with 3D hip adduction angle, ranging from r = 0.70–0.90 across all tasks. Linear regression analysis (r2) revealed that 49–81% of 3D hip adduction angle can be explained by 2D measurement.ConclusionIt might be difficult to explain 3D knee abduction angle using 2D video analysis during single leg landing tasks, whereas 2D hip adduction angle is a strong predictor or 3D hip adduction angle. It would appear 2D video analysis has strong concurrent validity when assessing hip adduction angle, but it is weak when assessing knee abduction angle during a variety of single leg landing tasks.
  • Seasonal variation in neuromuscular control in young male soccer players
    • Abstract: Publication date: March 2020Source: Physical Therapy in Sport, Volume 42Author(s): Rhodri S. Lloyd, Jon L. Oliver, Gregory D. Myer, Mark De Ste Croix, Paul J. ReadAbstractObjectiveDetermine how lower limb neuromuscular control changes over the course of a competitive soccer season.DesignRepeated measures.SettingAcademy soccer club.Participants43 male youth soccer players (age 13.1 ± 2.2 yr; height 160.1 ± 15.7 cm; body mass 49.4 ± 14.3 kg; maturity offset 0.2 ± 1.9 yr).Main outcome measuresPre-, mid- and end of season assessments of peak landing forces during single leg 75% horizontal hop and stick (75%HOP) and a single leg countermovement jump (SLCMJ), single leg hop for distance (SLHD), knee valgus during the tuck jump assessment (TJA) and inter-limb symmetries.ResultsHop distance increased significantly. Absolute peak landing forces in the left leg during the SLCMJ and 75%HOP increased significantly, with significant increases also present in the same leg for SLCMJ relative peak landing force. TJA knee valgus score was reduced in the right leg, but remained at a ‘moderate’ level in the left knee.ConclusionNeuromuscular control, as evidenced by increased absolute and relative peak landing forces, appears to reduce over the course of a competitive season. Young soccer players should engage in neuromuscular training throughout the season to offset any decrements in neuromuscular control and to facilitate appropriate landing strategies.

  • An investigation into the role of gluteal muscle strength and EMG activity
           in controlling HIP and knee motion during landing tasks
    • Abstract: Publication date: Available online 2 January 2020Source: Physical Therapy in SportAuthor(s): Ziyad Neamatallah, Lee Herrington, Richard JonesAbstractObjectivesTo examine the relationship between gluteal muscle activity and strength and knee and hip biomechanics during single leg loading tasks.DesignCorrelation study.SettingUniversity Biomechanics laboratory.Participants34 physically active, healthy participants, (17 males and 17 females).Main outcome measuresgluteal muscle EMG activity; hip abduction and extension muscle strength; knee and hip angles and moments.ResultsIn females knee abduction moments and angles were strongly correlated to hip abduction strength across all tasks, whereas in males the relationships were less clear across tasks with both hip abduction strength and gluteus medius EMG activity showing the strongest relationships in specific tasks.ConclusionHip and knee kinetic and kinematic variables related to the development of dynamic knee valgus would appear to be influenced by gluteal muscle strength and EMG activity. The level of influence varies across single leg squatting and landing tasks and varies between genders.
  • Neurocognitive challenged hops reduced functional performance relative to
           traditional hop testing
    • Abstract: Publication date: January 2020Source: Physical Therapy in Sport, Volume 41Author(s): Janet E. Simon, Nathan Millikan, Jae Yom, Dustin R.

  • The Evalaution Of The Foot Core System In Individuals With Plantar Heel
    • Abstract: Publication date: Available online 29 November 2019Source: Physical Therapy in SportAuthor(s): Hogan KK, Prince JA, Hoch MCAbstractObjectiveTo compare foot posture, plantar sensation, plantar fascia thickness, intrinsic foot muscle performance, and abductor hallucis morphology in individuals with and without plantar heel pain (PHP).DesignCross-Sectional.SettingLaboratory.ParticipantsSixteen individuals with PHP and sixteen matched healthy participants.Main Outcome MeasuresStatic foot posture, plantar sensation, plantar fascia thickness, intrinsic foot muscle performance and abductor hallucis morphology were evaluated. Foot posture was assessed with the Foot Posture Index-6. Abductor hallucis morphology and plantar fascia thickness were measured utilizing diagnostic ultrasound. Plantar foot sensation was assessed at the head of the first metatarsal and medial longitudinal arch using Semmes-Weinstein Monofilaments. Intrinsic foot muscle performance was assessed using the intrinsic foot muscle test (IFMT). Mann-Whitney U and independent t-tests were used to examine between group differences.ResultsIndividuals with PHP exhibited a more pronated foot posture and greater plantar fascia thickness at the proximal insertion compared to healthy controls. Plantar sensation thresholds were higher in the PHP compared to healthy controls at the head of the first metatarsal. There were no group differences in abductor hallucis morphology or IFMT performance.ConclusionsIndividuals with PHP exhibited a more pronated foot posture, thicker plantar fascia, and diminished plantar tactile sensation.

           without chronic ankle instability
    • Abstract: Publication date: Available online 28 November 2019Source: Physical Therapy in SportAuthor(s): Mark Colapietro, John J. Fraser, Jacob E. Resch, Jay HertelAbstractObjectiveTo evaluate biomechanical measures in runners with and without chronic ankle instability (CAI) using wearable sensors during two 1600 m track runs at a slow- and fast-pace.DesignObservational case-control.SettingField.Participants18 recreational runners (CAI: n = 9; Healthy: n = 9) with rearfoot strike patterns.Main outcome measuresPronation excursion, maximum pronation velocity, peak braking g, peak impact g, contact time, cycle time, and stride length of every step of two 1600 m runs were collected using RunScribe™ sensors and binned to each 400 m lap (Lap 1 to Lap 4).ResultsSignificant group-by-lap interactions were identified for contact time (p = .05) during the slow-intensity run. The CAI group had greater contact time (p = 0.05) that progressively increased with distance completed. CAI group also had higher impact g than the control group throughout the slow-intensity run (p = .03). During the fast-intensity run, significant group by lap interaction was observed for pronation excursion with the CAI group exhibiting less pronation excursion than the healthy group as the run progressed (p = .002).ConclusionsRegardless of speed, runners with CAI demonstrated altered gait mechanics compared to healthy controls. During the higher intensity run, decreased pronation excursion was observed in the CAI group and differences became more prominent as the distance increased.
  • Incidence of injuries among professional football players in Spain during
           three consecutive seasons: a longitudinal, retrospective study
    • Abstract: Publication date: Available online 19 November 2019Source: Physical Therapy in SportAuthor(s): Gabriel Gijon-Nogueron, Marcelino Torrontegui-Duarte, Juan Carlos Perez-Frias, Jose Miguel Morales-Asencio, Alejandro Luque-SuarezAbstractObjectivesThe aim of the study was to determine risk factors that maybe be associated with a higher incidence of injuries in elite football players in the Spanish league during a three-year follow-up. Injury was defined as a musculoskeletal complaint (pain and/or discomfort) reported by players to the medical staff and receiving medical attention.DesignA longitudinal retrospective studySettingand participants: Seventy-one players from Malaga Football Club, who were in the first squad team for three consecutive seasonsMain Outcome measuresIncidence, location, severity of injuries were reported according to the Injury Consensus Group for football injuries.ResultsThree hundred and fifty six injuries were found, with the highest proportion (44%) being located in the thigh. We found 6.9 (SD 5.87) injuries per 1000 hours of match time and 0.23 (SD 0.22) per 1000 hours of training. Forwards presented the highest rates in both incidence and severity of injury. Exposure to training was inversely related to the total number of injuries, which means that the greater the exposure to training the lesser the number of injuries.ConclusionsThis information can assist clinicians in the identification of risk factors and, thus, the elaboration of prevention programmes that reduce football injuries.
  • Does external workload accurately predict lower-back injuries in cricket
           fast bowlers' A systematic review
    • Abstract: Publication date: Available online 17 November 2019Source: Physical Therapy in SportAuthor(s): Corey Perrett, Peter Lamb, Melanie BusseyAbstractObjectiveTo examine the level of evidence for an association between external bowling workload and lower-back injuries in cricket fast bowlers.MethodsSix online databases were searched using four sets of keywords (relating to cricket, bowler, lumbar, workload). Risk of bias was assessed using the NIH quality assessment tool, while quality of evidence was assessed according to the Cochrane Back and Neck (CBN) group guidelines.ResultsEight articles were found to fit the inclusion/exclusion criteria. It was found that overall, there was a low quality of evidence amongst the included studies. A high risk of bias was present – both in the measurement of external workload and lower-back injuries.ConclusionThe association between external workload and lower-back injuries has minimal strength. Technological advancements that allow total workload to be measured accurately would potentially allow the association between workload and lower-back injury to be examined more precisely, possibly leading to effective injury prevention interventions in fast bowlers.

Kemler, B.M.A. HuisstedeAbstractObjectiveTo investigate which preventive measures runners use when preparing for a half- or full-marathon and whether the use of these measures at baseline and during the preparation-period differs between runners who sustained no/non-substantial running-related injuries (NSIRs) or substantial running-related injuries (SIRs).DesignProspective cohort study.Setting16-week period before the XXXXX-marathon.ParticipantsRunners who subscribed for the half- or full-marathon.Main outcome measuresThe occurrence of RRIs was registered every 2-weeks, using the Dutch version of the Oslo Sport Trauma Research Center (OSTRC) questionnaire on Health Problems. The OSTRC was used to differentiate between runners with SIRs (question 2/3 score>12 and NSIRs (question 2/3 score
  • Prevalence and unique patterns of lower limb hypermobility in elite ballet
    • Abstract: Publication date: Available online 14 November 2019Source: Physical Therapy in SportAuthor(s): Katie Phan, Leslie L. Nicholson, Claire E. Hiller, Cliffton ChanAbstractObjectivesDetermine the prevalence of lower limb hypermobility in elite dancers and secondarily to describe the patterns of mobility.DesignCross sectional.SettingSelf-report questionnaires and physical assessments were undertaken at a tertiary dance institution and a professional ballet company.ParticipantsFifty-seven pre-professional and 29 professional ballet dancers (21±4years, 64% female, mean 13.7years training) were recruited.Main outcome measuresLower Limb Assessment Score (LLAS) was used to assess hypermobility. Prevalence was determined by descriptive statistics, between-leg and -group comparisons were analysed using the chi-square statistic and the pattern of mobility by cluster analyses.ResultsThe right leg was significantly more hypermobile than the left for the whole cohort (44% vs 40% meeting ≥7/12 for the LLAS; LLAS mean/12(SD): right:5.0(2.4) and 7.6(1.9); left:4.8(2.1) and 6.7(2.0) in pre-professionals and professionals respectively (p = 0.02)).

  • Conversion to a rearfoot strike pattern during running for prevention of
           recurrent calf strains: A case report
    • Abstract: Publication date: Available online 9 November 2019Source: Physical Therapy in SportAuthor(s): Ari Baquet, Brittney Mazzone, Adam Yoder, Shawn FarrokhiAbstractBackgroundRunning-related injuries are prevalent musculoskeletal complaints in the United States military. Although, run retraining is an extensively researched method for reducing pain and improving function in runners, its clinical utility remains low.Case descriptionThe patient had a seven-year history of recurrent right calf strains. Prior conventional physical therapy failed to resolve symptoms. A biomechanical running analysis revealed a right forefoot strike during running. The patient underwent run retraining that included real-time visual feedback and a faded feedback strategy focused on converting foot strike pattern to rearfoot. Running mechanics were reassessed post-training, and at one and six months post-training.OutcomesFoot strike pattern was successfully converted to rearfoot strike and was maintained up to six months post-training. Reductions in peak ankle dorsiflexion moment and dorsiflexion velocity were noted up to six months post-training. Self-reported function also improved by 20–30% and no calf strains were reported up to six months post-training.DiscussionThis case report details the clinical reasoning and evidence-informed interventions involved in treatment of a patient with chronic calf strains. The management strategy was intended to reduce eccentric calf demands, which allowed the patient to tolerate increased running frequency without any further episodes of calf strains up to six months post-training.

  • A randomised observational study of individualised variations in the start
           position of the closed-kinetic chain upper extremity stability test
    • Abstract: Publication date: Available online 23 October 2019Source: Physical Therapy in SportAuthor(s): Andrew Callaway, Joshua Peck, Shelley Ellis, Jonathan WilliamsAbstractObjectivesTo assess the reliability, precision and differences between scores produced using the standard 36″” start position and 3 modified start positions of the Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST), towards normalisation to the individual.DesignRCT of 4 conditions.SettingClinical.ParticipantsThirty-four asymptomatic individuals.Main outcome measuresUsing an RCT method, variations in CKCUEST starting hand position were tested using hand spacing at standard 36″, 50% height, bi-acromial distance, and bi-acromial distance with reach to 36″. The average number of touches over 3 × 15 s maximal efforts were averaged. The intra-variation reliability, minimum detectable change (MDC) and differences to the standard 36″” start position were tested.ResultsThe most reliable variation was the 50% height (ICC: 0.93) and with the smallest MDC (14%). 36″ results were second-most reliable (ICC: 0.90), with a low MDC (19%). Significant differences were found between bi-acromial and 50% height to the 36″” standard setup.ConclusionsA setup position where the hand separation is 50% of the individual's height offers excellent repeated measures reliability and the smallest MDC, suggesting it is the most sensitive to change and is a recommendation to clinicians. Conversion calculations between start variations are presented.
  • Worse knee confidence, fear of movement, psychological readiness to
           return-to-sport and pain are associated with worse function after ACL
    • Abstract: Publication date: Available online 22 October 2019Source: Physical Therapy in SportAuthor(s): Harvi F. Hart, Adam G. Culvenor, Ali Guermazi, Kay M. CrossleyAbstractObjectivesTo determine whether knee confidence, fear of movement, psychological readiness to return-to-sport or pain are associated with patient-reported and performance-based function and return to pivoting sport in individuals one-year after anterior cruciate ligament reconstruction (ACLR).DesignCross-sectional study.SettingUniversity-laboratory.Participants118 individuals one-year post-ACLR.Main outcome measuresThe KOOS-sport/recreation and IKDC and three hopping tasks were used to assess patient-reported and performance-based function, respectively. Questions regarding return to pivoting sports assessed return-to-sport status. Fear of movement (Tampa Scale), knee confidence (an item from KOOS, Visual Analogue Scale-VAS confidence during hopping tasks), knee pain (KOOS-pain, VAS pain during hopping tasks) and psychological readiness to return-to-sport (ACL-RSI) were also assessed.ResultsWorse fear of movement (p = 0.019), KOOS-pain (p 
  • Concussion reporting, knowledge and attitudes in Irish amateur gaelic
           games athletes
    • Abstract: Publication date: Available online 8 June 2019Source: Physical Therapy in SportAuthor(s): Róisín Leahy, Shane Farrington, Enda Whyte, Siobhán O'ConnorAbstractObjectivesTo examine self-reported concussion history, knowledge and attitudes towards concussion reporting and education in Irish adult Gaelic games players.DesignCross-sectional survey.SettingData were collected using an online survey instrument.ParticipantsTwo hundred and sixteen adult Gaelic games athletes (106 male, 110 female).Main outcome measuresSelf-reported concussion history for the previous season, reporting history for participants’ most recent concussion, concussion knowledge, willingness to report future concussions in a variety of situations and desire for further concussion education.ResultsSeventy-three percent of participants suspected they had sustained a concussion in the past. Most (72.2%) informed someone of their most recent concussion, although two-thirds continued to play during their most recent concussion. Participants had a good overall understanding of concussion, although concussion knowledge score was not associated with safer behaviour following participants’ most recent concussion. While most agreed that concussion is a serious injury (95.8%), 46.8% would not report a concussion during important games.ConclusionsThe high proportion of participants playing following concussion and their reluctance to report concussions during important games is concerning. Interventions aimed at improving attitudes towards concussion reporting among athletes and other stakeholders are required to improve concussion management in amateur Gaelic games athletes.
