Gymnastics is a unique athletic activity requiring different loading and weight bearing patterns through the entire body, especially the upper extremity (UE). Available literature on return to sport following a UE injury is predominately focused on return to throwing. Criteria regarding athlete appropriateness to return to UE weight bearing is limited. The purpose of this scoping review is to explore return to gymnastics and weight bearing following a UE injury. Computerized searches were performed using online databases. Grey literature, non-medical database sources and relevant study reference lists were manually reviewed. For screening and full-text determinations, two authors independently voted on inclusion based on established eligibility criteria and a third blinded author was used to resolve conflicts. Data related to interventions including any relevant protocols, outcomes, and return to sport criteria were extracted. In total, 1420 titles were retrieved. After duplicate removal, 1000 studies were screened, 40 were retained for final inclusion. Of the included studies, 8 specified return to gymnastics criteria. Limited and low-quality evidence of return to gymnastics following a UE injury was identified. The lack of evidence restricts clinical determination of readiness for return to UE loading making clinical care of gymnasts variable and potentially less effective.

体操是一项独特的体育活动，需要整个身体，特别是上肢的不同负荷和负重模式。关于UE损伤后恢复运动的现有文献主要集中在恢复投掷。关于运动员是否适合回到UE负重的标准是有限的。本综述的目的是探讨UE损伤后恢复体操和负重。计算机搜索使用在线数据库进行。手工审查灰色文献、非医学数据库来源和相关研究参考列表。对于筛选和全文确定，两位作者根据既定的资格标准独立投票决定纳入，第三位盲法作者用于解决冲突。提取与干预措施相关的数据，包括任何相关的方案、结果和恢复运动标准。总共检索了1420个标题。去除重复后，筛选了1000项研究，其中40项保留为最终纳入。在纳入的研究中，有8项研究明确了回归体操标准。有限的和低质量的证据恢复体操后，UE损伤被确定。缺乏证据限制了临床确定是否准备好返回UE负荷，使体操运动员的临床护理不稳定，并且可能不那么有效。

Objective

To compare the immediate effects of three ankle brace designs—a single-strap ankle brace (SPAB), a figure-eight elastic ankle brace (FEAB), and a semi-rigid ankle brace (SRAB)—on static balance, landing-related postural stability, perceived stability, and comfort in young adults with functional ankle instability (FAI).

Design

Randomised crossover laboratory study.

Setting

Biomechanics laboratory.

Participants

Twenty-two young adults with clinically defined FAI (21 unilateral, one bilateral).

Main outcome measures

Centre-of-pressure sway during single-leg quiet stance, dynamic postural stability indices during single-leg landing, and 100-mm visual analogue scales of perceived stability and comfort. Mediolateral sway velocity (Sway V-ML) and mediolateral stability index (MLSI) were prespecified as primary outcomes.

Results

FEAB reduced Sway V-ML versus unbraced (7.61%, p = 0.013, Cohen's d_av = 0.37) and total sway velocity versus unbraced, SPAB, and SRAB (5.69%–9.25%, all p ≤ 0.037). FEAB also reduced MLSI versus unbraced (10.61%, p < 0.001, d_av = 0.53) and SRAB (8.17%, p = 0.033, d_av = 0.38). Sway-area variables, DPSI, APSI, and VSI showed no significant differences. All braces increased perceived stability, whereas SRAB was least comfortable.

Conclusion

FEAB showed modest, direction-specific short-term benefits in mediolateral postural control without reducing comfort, supporting task-specific brace selection in FAI rehabilitation.

目的：比较三种踝关节支架设计-单带踝关节支架（SPAB）， 8字形弹性踝关节支架（FEAB）和半刚性踝关节支架(SRAB)-对年轻人功能性踝关节不稳定（FAI）的静态平衡，着陆相关姿势稳定性，感知稳定性和舒适性的直接影响。设计：随机交叉实验室研究。环境：生物力学实验室。参与者：22名临床确诊FAI的年轻人（21名单侧，1名双侧）。主要结果测量：单腿安静站立时的压力中心摇摆，单腿着陆时的动态姿势稳定性指数，感知稳定性和舒适度的100毫米视觉模拟量表。中外侧摇摆速度（sway V-ML）和中外侧稳定指数（MLSI）被预先指定为主要结果。结果：FEAB与未支架相比降低了摇摆V-ML (7.61%, p = 0.013, Cohen’s d_av = 0.37)，与未支架、SPAB和SRAB相比，总摇摆速度（5.69%-9.25%，均p≤0.037）。结论：FEAB在中外侧姿势控制方面表现出适度的、方向特异性的短期益处，而不降低舒适度，支持FAI康复中任务特异性支架的选择。

Objective

To investigate pre-season characteristics associated with in-season groin problems and to assess the discriminatory performance of clinical markers using a predictive modelling approach.

Design

Prospective cohort study.

Setting

Spanish female football (tiers II and III).

Participants

Thirty-seven players.

Main outcome measures

Pre-season assessments included isometric hip adduction (5-s squeeze test), hip mobility (bent-knee fall-out [BKFO]), adductor endurance (Brazilian Adductor Performance Test), HAGOS-Sport scores, and limb length. In-season groin problems were monitored via the OSTRC-O2 questionnaire.

Results

Fourteen players (37%) reported groin problems. Players who developed symptoms were older (g = 0.95), heavier (g = 0.87) and had lower adductor torque (g = −0.72) than uninjured counterparts. Adductor torque asymmetry (AUC = 0.86, 95% CI: 0.74–0.97) and BKFO test (AUC = 0.78, 95% CI: 0.64–0.94) showed the highest clinical predictive performance. While limb length also yielded high AUC, this requires cautious interpretation due to the sample size.

Conclusions

Pre-season adductor strength imbalance and hip mobility emerged as relevant indicators of groin problem risk in female football players. These findings highlight the potential utility of individualized screening to identify vulnerable players. However, the small sample size warrants cautious interpretation, and larger cohorts are needed to refine these predictive approaches.

目的：研究季节前与季节腹股沟问题相关的特征，并使用预测建模方法评估临床标志物的歧视性表现。设计：前瞻性队列研究。设置：西班牙女子足球（二级和三级）。参与者：37人。主要结果测量：季前评估包括髋内收（5秒挤压试验）、髋关节活动性（屈膝-膝关节脱出[BKFO]）、内收肌耐力（巴西内收肌性能测试）、HAGOS-Sport评分和肢体长度。通过OSTRC-O2问卷监测季节腹股沟问题。结果：14名球员（37%）报告腹股沟问题。与未受伤的球员相比，出现症状的球员年龄更大（g = 0.95），体重更重（g = 0.87），内收肌扭矩（g = -0.72）更低。内收肌扭矩不对称（AUC = 0.86, 95% CI: 0.74-0.97）和BKFO测试（AUC = 0.78, 95% CI: 0.64-0.94）表现出最高的临床预测性能。虽然肢长也产生了很高的AUC，但由于样本量的原因，这需要谨慎解释。结论：季前内收肌力量失衡和髋关节活动度是女性足球运动员腹股沟问题风险的相关指标。这些发现强调了个性化筛查在识别弱势球员方面的潜在效用。然而，小样本量保证了谨慎的解释，并且需要更大的队列来完善这些预测方法。

Objectives

To compare the effects of a 4-week dynamic, multidirectional therapeutic exercise (TEx) programme alone versus TEx combined with neuromuscular electrical stimulation (NMES) in individuals with chronic ankle instability (CAI).

Design

Randomised intervention study.

Setting

Laboratory.

Participants

Twenty physically active adults with CAI.

Main outcome measures

Participants were randomised to either a TEx group or an NMES group. Both groups completed the same 4-week dynamic, multidirectional therapeutic exercise programme, while the NMES group received bilateral peroneal stimulation during exercise sessions. Outcomes included the Cumberland Ankle Instability Tool (CAIT), the Lower Quadrant Y-Balance Test (LQ-YBT), and lower-limb muscle activation latency during inversion-simulation and drop-jump tasks.

Results

Both groups improved CAIT scores post-intervention (p < 0.001), although only NMES maintained improvements at follow-up (p < 0.001). NMES demonstrated greater reductions in inversion-related muscle activation latency across multiple muscles, including tibialis anterior and peroneus longus (p < 0.05). Within-group improvements in posteromedial, posterolateral, and composite LQ-YBT scores were observed in the TEx group (p < 0.05). Drop-jump outcomes demonstrated variable changes between groups.

Conclusions

NMES combined with TEx may improve the timing of neuromuscular activation during inversion-simulation tasks, while TEx showed within-group improvements in some dynamic balance outcomes.

目的：比较4周动态、多向治疗性运动（TEx）方案与TEx联合神经肌肉电刺激（NMES）对慢性踝关节不稳定（CAI）患者的效果。设计：随机干预研究。设置:实验室。参与者：20名患有CAI的成年人。主要结果测量：参与者被随机分为TEx组或NMES组。两组都完成了相同的为期4周的动态，多向治疗性运动计划，而NMES组在运动期间接受双侧腓骨刺激。结果包括坎伯兰踝关节不稳定工具（CAIT）、下象限y -平衡测试（LQ-YBT）和倒立模拟和落体跳跃任务期间的下肢肌肉激活潜伏期。结果：两组干预后的CAIT评分均有改善(p)。结论：NMES联合TEx可改善倒排模拟任务中神经肌肉激活的时间，而TEx可改善组内某些动态平衡结果。

Background

Injuries in youth sport remain a concern. Biological maturity has been linked to injury risk but there is limited female specific evidence.

Aim

To evaluate the evidence for an association between biological maturity and injury in young females participating in sport.

Methods

A systematic search was conducted using EBSCO Health database from inception until April 2025. Studies were included if they investigated females in any sport and reported an assessment of biological maturity status and either injury rate or potential factors associated with injury. Study quality and risk of bias and the strength of evidence for findings was determined based on the consistency and quality of studies.

Finding

31 studies (n = 10 reporting injury; n = 21 reporting risk factors) were included in the review. Evidence supporting an association between injury and maturation was limited. There is moderate evidence of an association between potential injury risk factors and maturation. Most evidence is in the context of lower limb biomechanics during jump/landing tasks and potential risk of knee injury.

Conclusion

Current evidence for a link between maturity status and sport related injury in young females is limited, however there is moderate evidence that maturity status is associated with potential knee injury risk factors.

背景：青少年体育运动中的伤病仍然是一个令人担忧的问题。生理成熟度与受伤风险有关，但针对女性的证据有限。目的：评价年轻女性参加体育运动的生理成熟度与损伤之间的关系。方法：系统检索EBSCO Health数据库自成立至2025年4月。如果他们调查了任何运动中的女性，并报告了生物成熟状态的评估，受伤率或与受伤相关的潜在因素，则研究被纳入其中。研究质量、偏倚风险和研究结果的证据强度是根据研究的一致性和质量来确定的。结果：31项研究（n = 10报告损伤，n = 21报告危险因素）被纳入本综述。支持损伤与成熟之间关联的证据有限。有中度证据表明潜在的损伤危险因素与成熟之间存在关联。大多数证据是在跳跃/着陆任务和膝盖损伤的潜在风险时下肢生物力学的背景下。结论：目前关于年轻女性成熟状态与运动相关损伤之间联系的证据有限，但是有中度证据表明成熟状态与潜在的膝关节损伤危险因素相关。

Objectives

To evaluate the reliability and validity of a clinic-friendly protocol using a weight-based knee extension (WBKE) machine to assess quadriceps symmetry after anterior cruciate ligament (ACL) reconstruction, compared to isokinetic dynamometry (IKD).

Design

Cross-sectional reliability and validity study.

Setting

Orthopedic rehabilitation and sports medicine clinic.

Participants

Seventy-four individuals (aged 16–50 years) between 6 and 14 months post-ACL reconstruction.

Main outcome measures

Test-retest reliability (intraclass correlation coefficients, ICC) and validity (limb symmetry index, Pearson's correlation, linear regression, Bland-Altman analysis) of WBKE compared to IKD.

Results

The WBKE test showed excellent test-retest reliability (ICC = 0.94–0.98). The limb symmetry index was 90.6% ± 12.4% for IKD and 87.5% ± 12.5% for WBKE, with a mean difference of −3.16% (95% CI: −4.8 to −1.5, p < 0.001). Bland-Altman analysis indicated 95% limits of agreement from 8.31% to −14.63%. The correlation between WBKE and IKD was strong (r = 0.89, 95% CI: 0.81–0.94, p < 0.001), supported by linear regression (R² = 0.79, p < 0.001).

Conclusions

The WBKE test demonstrated excellent reliability and strong validity for assessing quadriceps symmetry post-ACL reconstruction. It offers a practical, accessible alternative to isokinetic testing for monitoring strength recovery in clinical practice.

目的：与等速动力学（IKD）相比，评估使用基于重量的膝关节伸展（WBKE）机评估前交叉韧带（ACL）重建后股四头肌对称性的临床友好方案的可靠性和有效性。设计：横断面信度和效度研究。单位：骨科康复与运动医学门诊。参与者：74例（年龄16-50岁）acl重建后6- 14个月。主要观察指标：WBKE与IKD的重测信度（类内相关系数，ICC）和效度（肢体对称指数、Pearson相关、线性回归、Bland-Altman分析）。结果：WBKE检验具有良好的重测信度（ICC = 0.94 ~ 0.98）。IKD组四肢对称指数为90.6%±12.4%，WBKE组为87.5%±12.5%，平均差异为-3.16% （95% CI: -4.8 ~ -1.5, p 2 = 0.79, p）结论：WBKE测试对评估acl重建后股四头肌对称性具有良好的信度和强效度。它提供了一个实用的，可访问的替代等速测试监测强度恢复在临床实践。

Objectives

To explore what determines patients’ decisions to return to sport (RTS) after an ACL-injury, treated with or without reconstruction (ACLR).

Design

Prospective multicentre cohort study.

Participants

275 patients with acute ACL-injury treated according to clinical practice were followed.

Main outcome measure

Answers to the free-text question: “What determined your decision to RTS?”, analysed using qualitative content analysis.

Results

134 patients reported RTS and 112 of these (56% after ACLR), answered the question. A total of 271 meaning units were condensed into 50 codes, nine subcategories, and three categories: “motivation and driving forces”, “treatment and recovery”, “medical clearance and readiness”, with the overarching theme “mindset, effort, and support—the foundation for patients' decision to RTS”. Answers were similar regardless of ACL treatment (ACLR or not). Passion for sport and willpower were strong motivators, outweighing shortcomings and fears. Structured rehabilitation, combined with patients' engagement, hard work, self-perceived readiness, and support from surrounding personnel, including medical clearance, were other factors influencing patients’ decision to RTS.

Conclusions

The theme, capturing the key components “mindset, effort, and support”, summarises what determined patients’ decisions to RTS. This may help clinicians identify what to emphasise during the long and demanding process from injury to RTS.

目的：探讨是什么因素决定了患者在acl损伤后恢复运动（RTS）的决定，无论是否进行重建（ACLR）。设计：前瞻性多中心队列研究。对象：对275例急性acl损伤患者进行临床随访。主要结果测量：回答自由文本问题：“是什么决定了你选择RTS?”，使用定性内容分析进行分析。结果：134例患者报告了RTS，其中112例（56%为ACLR后）回答了这个问题。271个意义单位被浓缩成50个代码、9个子类别和3个类别：“动机和驱动力”、“治疗和康复”、“医疗许可和准备”，总体主题是“心态、努力和支持——患者决定RTS的基础”。无论ACL治疗（是否ACLR），答案相似。对运动的热情和毅力是强大的动力，超过了缺点和恐惧。有组织的康复，结合患者的参与、努力工作、自我感知的准备和周围人员的支持，包括医疗许可，是影响患者决定进行RTS的其他因素。结论：该主题捕捉了“心态、努力和支持”的关键组成部分，总结了决定患者选择RTS的因素。这可能有助于临床医生确定在从受伤到RTS的漫长而苛刻的过程中应该强调什么。

Objectives

Compare the efficacy and acceptability of low load blood flow restriction (BFR) using two different limb occlusion pressures (LOP) on pain and function in individuals with lower-limb musculoskeletal injury (MSKI) and associated persistent pain.

Design

Randomised controlled trial within a military residential rehabilitation setting.

Participants

Twenty-eight individuals (N = 21 male; N = 7 female) with lower-limb MSKI were randomly allocated into: 1) BFR-RE with 80% LOP (BFR80), or 2) BFR-RE with 40% LOP (BFR40). Both groups completed 7x BFR-RE sessions during 5-days of residential rehabilitation at 20% 1-repetition maximum.

Main outcome measures

The primary outcome measure was the Brief Pain Inventory (BPI). Secondary outcomes include injury-specific outcomes, pain pressure threshold (PPT) and lower-limb muscle strength assessment. All reported outcomes reflect changes in scores.

Results

BPI ‘worst’ displayed a time × group interaction (p = .013), driven by higher pain in BFR80 from pre-to post-intervention (standardised mean difference [SMD] = 1.532, p = .006). There was a significant time × group interaction for BPI ‘severity’ (p = .022), driven by significant between-group differences at T3 (BFR80-BFR40: SMD = 1.305, p = .015). PPTs improved within-session and over time.

Conclusion

Both pressures demonstrated cumulative exercise-induced hypoalgesia via rising PPTs. BFR80 reported increased ‘worst’ pain score. Lower LOP may better preserve training volume and exercise tolerability.

目的：比较两种不同肢体闭塞压力（LOP）低负荷血流量限制（BFR）对下肢肌肉骨骼损伤（MSKI）及相关持续性疼痛患者疼痛和功能的疗效和可接受性。设计：在军事住宅康复环境中进行随机对照试验。参与者：28例下肢MSKI患者（男21例，女7例）随机分为：1)80% LOP的BFR-RE （BFR80）和40% LOP的BFR-RE （BFR40）。两组在5天的住宅康复期间均完成7次BFR-RE训练，每次最多重复20%。主要观察指标：主要观察指标为短期疼痛量表（BPI）。次要结局包括损伤特异性结局、痛压阈值（PPT）和下肢肌肉力量评估。所有报告的结果都反映了分数的变化。结果：BPI“最差”表现出时间×组交互作用（p = 0.013），由干预前和干预后BFR80的更高疼痛驱动（标准化平均差[SMD] = 1.532, p = 0.006）。T3组间差异显著（BFR80-BFR40: SMD = 1.305, p = 0.015），导致BPI“严重程度”存在显著的时间×组间相互作用（p = 0.022）。PPTs在治疗期间和一段时间内都有所改善。结论：两种压力均通过升高的PPTs表现出累积性运动诱导的痛觉减退。BFR80报告了“最差”疼痛评分的增加。较低的LOP可以更好地保持训练量和运动耐受性。
