Objectives

Hip and groin injury is more common in male athletes, but no systematic review has examined its prevalence and incidence in female field invasion team sport.

Methods

Six databases were searched independently by two authors who selected eligible studies, assessed risk of bias and extracted data. Studies reporting the prevalence and/or incidence of hip and groin injury were included. Proportional meta-analyses provided pooled estimates and the Grading of Recommendations Assessment, Development and Evaluation system determined the strength of evidence.

Results

Twenty-five articles were selected for inclusion. The prevalence of time loss hip and groin injury ranged from 0 to 74 % (4.42 %, 1.91, 9.91), while non-time loss cases ranged from 1 to 35 % (9.54 %, 1.15, 48.91). Time loss cases represented 0–17 % of total injuries (4.10 %, 2.54, 6.56). The strength of the evidence for pooled estimates was very low due to inconsistency and publication bias. Incidence rates ranged from 0.3 to 1.02 per 1000 athlete-hours. Adductor-related injury was the most frequently reported diagnosis.

Conclusion

Hip and groin injury in female field sports is common but rates vary due to heterogeneity across studies. Standardised definitions and methodological approaches must be employed in future studies to facilitate data pooling and better quantify the injury burden in this cohort.

Objectives

To investigate how modifiable landing platforms influence intra-foot movement during single-leg landings, comparing forefoot and hindfoot kinematics between individuals with chronic ankle instability (CAI) and controls to inform segment-focused rehabilitation strategies.

Design

Cross-sectional.

Setting

Biomechanics laboratory.

Participants

20 university students, 12 with CAI, 8 controls.

Main outcome measures

Participants performed single-leg landing on platforms with three orientations (inverted, plantarflexed-everted-abducted and dorsiflexed-inverted-adducted), and four inclinations (10°, 12°, 14°, 16°). These configurations were based on prior studies and safety limits. Net frontal-plane movement of the forefoot and hindfoot was calculated across a 400ms window.

Results

The CAI group showed significantly greater forefoot inversion (η² = 0.32; p < 0.01) and non-significant group difference in hindfoot eversion (ƞ² = 0.183; p = 0.06). Orientation and inclination had large effects on forefoot motion (η² = 0.56 and 0.80, respectively; p < 0.001). A significant group × segment interaction (η² = 0.24; p < 0.001) indicated contrasting movement between the forefoot and hindfoot in CAI, not observed in controls.

Conclusion

Individuals with CAI demonstrated a less adaptive, segment-specific landing strategy. Findings support the use of modifiable platforms and multi-segment foot models to guide targeted interventions addressing forefoot compensation and improving segmental control during landing.

目的通过比较慢性踝关节不稳定（CAI）患者和对照组患者的前足和后足运动学，研究可改变的着地平台如何影响单腿着地时的足内运动，从而为以足部为重点的康复策略提供依据。主要结果测量参与者在三种方向（倒置、跖屈-倒立-内收和背屈-倒立-内收）和四种倾角（10°、12°、14°、16°）的平台上进行单脚着地。这些配置是根据先前的研究和安全限制确定的。结果 CAI 组的前足内翻（η2 = 0.32; p < 0.01）明显大于 CAI 组，后足外翻（ƞ2 = 0.183; p = 0.06）的组间差异不明显。方向和倾斜度对前脚掌运动有很大影响（η2 = 0.56 和 0.80，p <0.001）。明显的组别 × 区段交互作用（η2 = 0.24; p <0.001）表明 CAI 患者的前脚掌和后脚掌之间的运动形成了鲜明对比，而对照组中没有观察到这一现象。研究结果支持使用可修改的平台和多节足模型来指导有针对性的干预措施，以解决前足补偿问题并改善着地过程中的节段控制。

Objectives

Examine the effects of hip-focused strengthening and task-specific movement training for a female who has undergone multiple surgical procedures yet continues to experience chronic, recurrent FAIS-related symptoms.

Study design

Case Report.

Methods

A 23-year-old active female with an eleven-year history of FAIS and two previous surgical procedures recently experienced a third recurrence of symptoms brought on by increased physical activity levels. The patient performed progressive exercises focused on improving hip extension, abduction, and external rotation strength. The patient also received task-specific movement training aimed at minimizing hip adduction and internal rotation during movement that provoked her symptoms.

Results

Following treatment, the patient's self-reported hip pain during movement improved 2.2 points and was abolished during four of the five activities examined. The patient exhibited strength gains for the hip extensors (22 %), abductors (36 %), and external rotators (20 %). The patient exhibited decreased hip adduction during all activities (mean difference = 10.6°) and decreased hip internal rotation during three of the five activities (mean difference = 3.7°).

Conclusion

This case report highlights the effects of hip-focused strengthening and task-specific movement training for a patient with longstanding FAIS and multiple surgical procedures.

Objective

To identify the available Patient-reported Outcome Measures (PROMs) for assessing musculoskeletal complaints in para-athletes and to evaluate their psychometric properties, ultimately providing recommendations for their use.

Methods

PubMed, Embase, Scopus, Cochrane Library, Web of Science, ProQuest, and COSMIN Database were searched until October 2024. Full report studies evaluating psychometric properties of PROMs in para-sport participants with musculoskeletal pain were included. The methodology followed the Consensus-based Standards for selection of Health Measurement Instruments (COSMIN) and PRISMA-COSMIN for OMIs 2024 Guidelines.

Results

Six articles reported information on Wheelchair User's Shoulder Pain Index (WUSPI); Shoulder Pain Scale for Wheelchair Basketball (SPS-WB); and, Shoulder Pain Index for Wheelchair Basketball (SPI-WB). Content validity was inconsistent for WUSPI and SPS-WB. Structural validity was indeterminate for SPS-WB. Internal consistency was sufficient for SPS-WB but indeterminate for WUSPI and SPI-WB. Reliability was sufficient for WUSPI and SPI-WB. Convergent validity was sufficient for WUSPI but indeterminate for SPS-WB and SPI-WB. Discriminative validity was insufficient for WUSPI and SPI-WB and indeterminate for SPS-WB.

Conclusions

Evidence on PROMs for musculoskeletal complaints in para-sports focuses on shoulder pain in wheelchair basketball, showing low to very low-quality evidence. The WUSPI and SPS-WB can be used considering their limitations.

Objectives

To clarify the prevalence and severity of injuries and illnesses in university handball players.

Design

Prospective cohort study.

Setting

Survey-based online questionnaire.

Participants

231 university handball players (109 males and 122 females) over 38 weeks.

Main outcome measures

Each participant completed the Japanese version of the Oslo Sports Trauma Research Center Questionnaire on Health Problems every Sunday. The main outcome measures were the average weekly prevalence of injuries and illnesses, duration, average weekly severity scores rated on a scale of 0–100 based on answers to four key questions, and cumulative severity scores.

Results

The average weekly prevalence was 27.4 % (95 % CI: 25.6–29.1 %) for injuries and 2.2 % (95 % CI: 1.6–2.8 %) for illnesses. Among injuries, traumatic injuries had higher average weekly severity scores (50.0 vs 32.0, p < 0.05) and cumulative severity scores per case (65.0 vs 42.0, p < 0.05) than overuse injuries. Conversely, overuse injuries lasted approximately 10 days longer than traumatic injuries (18 days vs 10 days, p < 0.05). Traumatic knee injuries and overuse shoulder injuries ranked the highest in prevalence, duration, and cumulative severity scores.

Conclusions

We found that, although overuse injuries were less severe than traumatic injuries, they interfered with handball activities for extended periods.

Rachel K. Straub, Adam J. Barrack, Jordan Cannon, Christopher M. Powers

Objective

To determine what combination of relative trunk and tibia inclination and knee flexion biases the hip and knee extensors during the squat.

Design

Repeated measures.

Setting

University research laboratory.

Participants

16 healthy individuals.

Main Outcome Measures

The average hip/knee extensor moment ratio (HKR) was calculated during squat descent, and trunk-tibia inclination difference and knee flexion angle at peak knee flexion. A regression tree for repeated measures determined what combination of trunk-tibia inclination difference and knee flexion angle predicted HKR.

Results

HKR was predicted by trunk-tibia inclination difference (primary predictor) and knee flexion (secondary predictor). Four squatting strategies emerged: knee extensor bias (average HKR = 0.3), neutral bias (average HKR = 0.9), hip extensor bias (average HKR = 1.5), and high hip extensor bias (average HKR = 2.2). When trunk inclination exceeded tibia inclination ( ≥ 2.2°), hip-biased squatting was evident. Squat depth affected only hip-biased squatting: high hip extensor bias at moderate depths (<96° knee flexion), and a less pronounced hip bias at greater depths ( ≥ 96° knee flexion).

Conclusions

Our results provide a framework to bias the squat exercise based on intent. To maximize or minimize hip relative to knee extensor demands, clinicians should be cognizant of the trunk inclination relative to tibia inclination and the influence of knee flexion.

Objective

To evaluate the effectiveness of adding Dynamic Tape® to a progressive load exercise program in patients with patellar tendinopathy.

Design

Randomized controlled trial.

Setting

University research.

Participants

Forty-eight subjects with patellar tendinopathy.

Methods

Participants were divided into two groups: dynamic group, which received progressive load exercises and Dynamic Tape®, and sham group, which received progressive load exercises and sham taping. The intervention was conducted three times per week over 12 weeks.

Main outcome measures

The pain during decline squatting was assessed using a visual analog scale. The severity of patellar tendinopathy was measured using the Victorian Institute of Sport Assessment-Patella (VISA-P).

Results

There was no effect of group-time interaction for the pain (Z = 0.844, p = 0.472) or severity (Z = 1.275, p = 0.286) of patellar tendinopathy. Reduced pain and severity were observed over time (p < 0.05), however there was no between-group differences (p > 0.05).

Conclusion

Dynamic Tape® does not provide additional benefits when combined with a progressive load exercise program for reducing pain and severity in patellar tendinopathy.

Objectives

The purpose of this study was to explore how Spanish physiotherapists manage Achilles tendinopathy and to evaluate the alignment of their practices with established clinical guidelines.

Design

A cross-sectional online survey of Spanish physiotherapists.

Setting

Clinical environment.

Participants

Four hundred thirty-four physiotherapists completed the survey.

Methods

An online survey was administered to Spanish physiotherapists between March and April 2024. The survey collected data on clinicians’ demographics, treatment approaches, and preferences. Descriptive analysis was performed, with nominal and ordinal data analyzed through frequency counts.

Results

Valid responses were received from 434 physiotherapists with a mean age of 32 years (IQR = 15, range 22–60). Exercise and education were the most used treatments (94 % and 78 % of respondents respectively), although there was variability in their implementation. However, a significant proportion of Spanish physiotherapists (64 %) reported using invasive techniques, which may reduce the time spent on evidence-based interventions (p = 0.001) for the management of Achilles tendinopathy.

Conclusions

Spanish physiotherapists generally follow clinical guidelines for managing AT, with exercise and education as the main interventions. Despite the limited evidence, invasive techniques and manual therapy (74 %) are widely used. Future research should clarify the impact of this practice in the Spanish population.

Objective

To investigate postural control deficits and their correlation with recurrent ankle sprains in patients with both chronic ankle instability (CAI) and chronic syndesmotic injury (CSI).

Design

Cross-sectional design.

Setting

Motion laboratory and Orthopedic department.

Participants

73 individuals with CAI and 15 healthy controls Main outcome measures: Patients with CAI were divided into a CAI group (isolated CAI) and a CSI group (CAI with CSI) based on arthroscopic findings. Postural control was evaluated using the Sensory Organization Test, Adaptability Test, and Romberg Test.

Results

The CSI group had significantly lower somatosensory, visual, and vestibular scores and higher visual dependency compared to CAI group and controls (p < 0.05-0.001). CSI groups showed higher sway energy than the CAI in the plantarflexion sway (p < 0.05). Correlation analysis indicated strong associations between sprain incidence and plantarflexion sway energy (r = 0.68, p < 0.001), VAS scores (r = 0.54, p < 0.001), and somatosensory deficits (r = −0.43, p < 0.001). The AUC for the logistic regression model was 0.906, indicating excellent model performance (p < 0.001).

Conclusions

Our results found that plantarflexion instability of the CSI correlates most strongly with the risk of ankle sprains, despite coexisting multisensory deficits. Hence, rehabilitation should address these deficits, pain management and targeted training.

Objectives

To determine associations between drop-jump vertical kinetics and acute non-contact knee injury-risk in male youth soccer players.

Design

Prospective cohort study.

Setting

Professional soccer academies.

Participants

Youth soccer players (n = 264).

Main outcome measures

Drop-jump vertical kinetics; injury epidemiology. Associations between kinetics and injury were assessed using binary logistic regression. Differences between injured and uninjured groups were compared using statistical parametric mapping.

Results

Peak braking: peak propulsive force ratio (OR = 1.59, 1.10–2.29, p < 0.05), propulsive work (OR = 0.53, 0.28–0.99, p < 0.05) and vertical stiffness (OR = 1.68, 1.13–2.52, p < 0.05) were associated with risk of sustaining a knee injury. All variables demonstrated ‘unusable’ or ‘weak’ levels of predictive ability in identifying players who would become injured (AUC 0.568–0.663).

Conclusions

Drop-jump vertical kinetics that characterise the shape of the force-time waveform provide insight to acute non-contact knee injury-risk in male youth soccer players. Large transient spikes in force in the early phase of ground contact, coupled with reduced propulsive forces are a risk factor for acute non-contact knee injury in male youth soccer players. Variables are not sensitive enough to predict injury but provide additional training targets to help mitigate risk in this population.
