Objectives

To describe features of risk appraisal after anterior cruciate ligament reconstruction (ACLR).

Study design

Secondary analysis.

Methods

161 patients with ACLR, cleared to initiate return to sport, were tested (initial and follow-up 6 weeks later). Patient characteristics, ACL-Return to Sport after Injury (ACL-RSI) score and limb symmetry index (LSI) on 4 single-leg hop tests were collected. ACL-RSI confidence domain and scores on risk appraisal items (#2: reinjure knee, #10: surgery/rehabilitation; both with respect to playing sports) were calculated. Risk appraisal items were analyzed for: change over time using effect sizes; correlations with age, sex, confidence domain score, and hop LSIs; and differences based on meeting readiness-for-sport criteria (ACL-RSI ≥70, hop LSIs ≥90 %).

Results

Risk appraisal item scores increased at follow-up (δ = 0.22, 0.26); higher scores were correlated with younger age (ρ = −0.25, −0.39), higher confidence domain score (ρ = 0.67, 0.60) and higher timed hop LSI (ρ = 0.24, 0.27). Patients meeting ACL-RSI/hop LSI or ACL-RSI criteria had significantly higher risk appraisal item scores than those meeting hop LSI or no criteria (p < 0.001).

Conclusions

Risk appraisal may evolve following ACLR. Patients with high confidence, and those exhibiting psychological readiness alone or in combination with physical readiness, tend to perceive lower risk with returning to sport.

目的探讨前交叉韧带重建术（ACLR）术后风险评估的特点。研究设计：二次分析。方法对161例ACLR患者进行测试（初始和随访6周后）。收集患者特征、损伤后恢复运动（ACL-RSI）评分和4次单腿跳试验的肢体对称指数（LSI）。ACL-RSI置信域和风险评估项目得分(#2：膝关节再损伤，#10：手术/康复；这两项都是关于运动的。对风险评估项目进行分析：使用效应量随时间的变化；与年龄、性别、置信域得分和跳跃lsi相关；以及基于满足运动准备标准的差异（ACL-RSI≥70,hop lsi≥90%）。结果风险评价项目得分随随访增高（δ = 0.22, 0.26）；得分越高，年龄越小（ρ =−0.25,−0.39），置信域得分越高（ρ = 0.67, 0.60），时间跳LSI越高（ρ = 0.24, 0.27）。符合ACL-RSI/hop LSI或ACL-RSI标准的患者的风险评估项目得分显著高于符合hop LSI或无标准的患者(p <；0.001)。结论ACLR后风险评估可能会发生变化。信心高的患者，以及那些表现出心理准备或身体准备的患者，倾向于认为重返运动的风险较低。

Objectives

Despite the important role of the trunk muscles in athletic performance and the onset of injury, consensus is lacking as to the best methods to assess trunk strength and endurance in athletic populations in the field. This study aimed to examine the intra-rater reliability of a battery of trunk strength and endurance tests.

Design

Test-retest reliability study.

Setting

Isometric trunk strength using a hand-held dynamometer (HHD) and isometric trunk endurance using the McGill protocol and novel ‘long-lever’ tests were evaluated.

Participants

Twenty-three male field-athletes.

Main Outcome Measures: Intra-class coefficient (ICC) and standard error of measurement (SEM).

Results

For relative reliability, good to excellent results were found for all HHD strength tests (ICC = 0.70–0.91). Relative reliability for trunk endurance tests showed excellent results for the McGill protocol (ICC = 0.80–0.89) and moderate to excellent reliability for the long-lever tests (ICC = 0.57–0.96). The V-Sit endurance test and the isometric lateral flexion strength test showed lower absolute reliability, with relatively high SEM values.

Conclusions

Therefore, we recommend practitioners assess athlete trunk function by using a HHD to evaluate isometric flexion, extension and rotation trunk strength and the Biering-Sørenson, and long-lever lateral flexion and flexion tests to assess trunk endurance.

尽管躯干肌肉在运动表现和损伤的发生中起着重要的作用，但对于评估该领域运动人群躯干力量和耐力的最佳方法仍缺乏共识。本研究旨在检验一组树干强度和耐力测试的内部可靠性。设计测试-重测可靠性研究。使用手持式测力仪（HHD）评估躯干的等距强度，使用McGill方案评估躯干的等距耐力，并对新型“长杆”测试进行评估。参与者：男性田径运动员23名。主要观察指标：类内系数（ICC）和测量标准误差（SEM）。结果在相对信度方面，所有HHD强度试验均获得良好至优异的结果（ICC = 0.70-0.91）。躯干耐力试验的相对信度显示麦吉尔方案的结果很好（ICC = 0.80-0.89），长杆试验的信度中等至优异（ICC = 0.57-0.96）。V-Sit耐久性试验和等距侧屈强度试验的绝对信度较低，SEM值相对较高。因此，我们建议从业人员通过HHD来评估运动员躯干功能，以评估躯干的等距屈曲、伸展和旋转强度以及biering - s - renson，并通过长杆侧向屈曲和屈曲测试来评估躯干耐力。

Objective

Runners value footwear advice provided by experts. It is therefore essential to understand the nature of these recommendations. This study identified factors influencing individualised running footwear recommendations and measured the relative importance placed on footwear characteristics related to comfort and injury management.

Design

Cross-sectional survey.

Setting

Online.

Participants

Podiatrists, physiotherapists, running coaches, and footwear retailers working in New Zealand.

Main outcome measures

Quantitative survey questions covering footwear recommendation habits, and beliefs regarding the functional capacity of running footwear.

Results

A total of 264 responses were received. Most participants identified comfort (96 %) and injury prevention (86 %) as important considerations in footwear selection. Retailers were more likely than other groups to emphasise the importance of arch height and foot motion (p < 0.001). Cushioning was rated the most influential characteristic for both comfort (99 %) and injury management (94 %). Most participants (91 %) thought medial posting influenced injury management, whilst shoe/upper width (95 %) and forefoot stiffness (93 %) were frequently linked to comfort. Significant differences emerged regarding beliefs about footwear functionality: 82 % of retailers believed that footwear could reduce pronation, compared to 55 % of podiatrists, 42 % of physiotherapists, and 29 % of coaches (p < 0.001).

Conclusions

Podiatrists and retailers provide individualised footwear advice more frequently and confidently and are more likely to base their recommendations on reducing pronation than physiotherapists and coaches.

Objectives

To examine associations between anthropometric properties and neck strength with linear and rotational accelerations during heading.

Design

Observational cohort study.

Participants

Eleven male footballers from a UK academy.

Main outcomes

Independent variables included head and neck circumference, head mass, head-neck segment mass, and strength. Dependent variables were mouthguard-derived linear and rotational acceleration.

Results

A total of 11 male footballer recorded 259 heading events (24 ± 8 per player). Trivial associations were observed between neck length, head-neck segment mass, and side flexion strength with linear acceleration (r = −0.04–0.18, p = 0.001–0.638). There was trivial-to-small association between neck circumference, head mass and strength in forward flexion and extension with linear acceleration (r = 0.05–0.33, p = 0.001–0.602). Neck circumference, head mass, and strength in forward flexion and extension showed trivial-to-small associations (r = 0.05–0.33, p = 0.001–0.602). Neck length, circumference, and side flexion strength showed trivial-to-large associations with rotational acceleration (r = −0.17–0.70, p < 0.001–0.166), while head mass, head-neck segment mass, and strength in flexion and extension had trivial-to-small associations (r = 0.01–0.75, p < 0.001–0.955). Fixed effects explained 4.3–6.5% of the variance in linear and rotational head accelerations.

Conclusion

Neck strength and anthropometric factors showed mixed associations with head accelerations during heading, explaining a small proportion of the variance in linear and rotational accelerations.

目的：研究头球过程中直线加速度和旋转加速度与人体测量特性和颈部强度之间的关系。设计：观察性队列研究。参与者：11名来自英国足球学院的男子足球运动员。主要结局：自变量包括头颈围、头质量、头颈段质量和力量。因变量为牙套导出的线性和旋转加速度。结果：11名男子足球运动员共记录头球事件259次（人均24±8次）。颈部长度、头颈段质量和侧屈曲强度与线性加速度之间存在轻微关联（r = -0.04-0.18, p = 0.001-0.638）。颈围、头质量和前屈、前伸强度与线性加速度之间存在小到小的关联（r = 0.05-0.33, p = 0.001-0.602）。颈围、头质量和前屈和前伸的力量表现出从小到小的相关性（r = 0.05-0.33, p = 0.001-0.602）。颈部长度、围度和侧屈曲强度与旋转加速度的相关性从小到大（r = -0.17-0.70, p）。结论：头球过程中，颈部强度和人体测量因素与头部加速度存在混合关联，这解释了线性和旋转加速度方差的一小部分。

Objective

To determine whether chronic ankle instability (CAI) individuals exhibit hip muscle strength deficits compared to healthy people.

Methods

A comprehensive search of five databases was conducted from inception to May 2025 according to PRISMA guidelines. Quality assessment of included studies was performed using the modified Downs and Black checklist, and meta-analysis was conducted using random-effects models with results reported as standardized mean differences (SMD).

Results

Ten studies involving 548 participants (271 CAI, 277 healthy controls) were included. Individuals with CAI demonstrated significantly decreased isometric hip abduction (SMD: 0.56, P < 0.001), extension (SMD: 0.62, P = 0.003), and external rotation strength (SMD: 0.59, P = 0.005) compared to controls. No significant differences were found in isokinetic strength at 60°/s. Sensitivity analysis showed unstable results for hip external rotation strength, while other outcomes remained stable.

Conclusion

Individuals with CAI demonstrated significant deficits in isometric hip abduction and extension strength compared to healthy people. Hip muscle strength assessment should be incorporated into routine examination of CAI individuals.

目的探讨慢性踝关节不稳定（CAI）患者与健康人相比是否表现出髋关节肌力不足。方法根据PRISMA指南对5个数据库进行综合检索，检索时间自成立至2025年5月。采用改进的Downs和Black检查表对纳入的研究进行质量评估，并采用随机效应模型进行meta分析，结果报告为标准化平均差异（SMD）。结果共纳入10项研究，共548人，其中CAI 271人，健康对照277人。CAI患者表现出显著减少髋外展(SMD: 0.56, P <；0.001)、伸展（SMD: 0.62, P = 0.003）和外旋强度（SMD: 0.59, P = 0.005）。60°/s的等速运动强度无显著差异。敏感性分析显示髋关节外旋强度的结果不稳定，而其他结果保持稳定。结论与健康人群相比，CAI患者在髋外展和髋外展力量方面存在明显缺陷。髋关节肌力评估应纳入CAI患者的常规检查。

Objective

The role of hip strength in the development of running related injuries is unclear. The aim of this study was to assess if runners who develop a running-related injury demonstrate less isometric hip strength than uninjured runners and to evaluate if runners demonstrating isometric hip weakness go on to experience more injuries than those with normal strength.

Design

Prospective cohort study.

Setting

University Campus.

Participants

Seventy-nine (29 male and 50 female) collegiate cross-country runners.

Main outcome measures

Running-related injury.

Results

Runners who sustained an injury demonstrated 13.6 % (p = 0.035) less hip abductor strength and demonstrated 16.6 % (p = 0.035) greater asymmetry in hip abductor strength. Runners identified as having a weakness in hip strength did not demonstrate a greater proportion of injuries than runners noted to have normal strength. The relative risk of sustaining a running-related injury was not greater in runners identified as having hip weakness.

Conclusions

Despite a theoretical link between hip weakness and the development of running-related injury, no difference in injury proportions was found in this cohort. However, differences in hip strength were identified between injured and uninjured runners. This may indicate that hip strength may mediate other factors that influence a runner's overall risk profile.

目的髋部力量在跑步相关损伤发生中的作用尚不清楚。这项研究的目的是评估发生跑步相关损伤的跑步者是否比未受伤的跑步者表现出更少的髋关节等距力量，以及评估表现出髋关节等距无力的跑步者是否会比那些力量正常的跑步者遭受更多的伤害。前瞻性队列研究。SettingUniversity校园。参与者：79名大学生越野跑运动员（29名男性，50名女性）。主要结果测量：跑步相关损伤。结果受伤的跑步者髋外展肌力量减少13.6% (p = 0.035)，髋外展肌力量不对称性增加16.6% （p = 0.035）。被认为髋部力量不足的跑步者受伤的比例并不比力量正常的跑步者高。在被确定为髋关节无力的跑步者中，维持与跑步有关的损伤的相对风险并不大。结论：尽管理论上存在髋关节无力与跑步相关损伤之间的联系，但在这一队列中没有发现损伤比例的差异。然而，在受伤和未受伤的跑步者之间发现了臀部力量的差异。这可能表明髋部力量可以调节影响跑步者整体风险概况的其他因素。

Objectives

This study aimed to investigate the associations of selected lower limb biomechanical variables with pain severity, disability, and postural balance in female athletes with Patellofemoral Pain Syndrome (PFPS).

Design

Cross-sectional study.

Setting

Biomechanics Laboratory.

Participants

165 female athletes were assigned to the PFPS group and 160 as a healthy controls group.

Main outcome measures

Dynamic knee valgus (DKV) was measured via the Kinovea software program, tibial torsion was measured via a universal goniometer, and the navicular height was measured via a height caliper tool. Postural balance under dynamic stress was quantified via the Biodex Balance System, Pain severity via the numerical pain rating scale (NPRS), and disability via the anterior knee pain scale (AKPS).

Results

DKV and tibial torsion showed significant differences between groups. DKV positively correlated with pain (r = 0.451) and postural balance (r = 0.244, 0.341, and 0.351 for balance scores), and negatively with disability (r = −0.432). Tibial torsion negatively correlated with disability (r = −0.339). Navicular height had no significant correlation with the measured variables.

Conclusions

Lower limb biomechanics, especially DKV and tibial torsion, should be prioritized in performance screening for female athletes. This study highlights the importance of addressing biomechanical correction strategies into rehabilitation programs for female athletes with PFPS.

目的：本研究旨在探讨髌骨股痛综合征（PFPS）女运动员下肢生物力学变量与疼痛严重程度、残疾和姿势平衡的关系。DesignCross-sectional研究。SettingBiomechanics实验室。165名女运动员被分配到PFPS组，160名作为健康对照组。主要结果测量：通过Kinovea软件程序测量动态膝外翻（DKV），通过通用测角仪测量胫骨扭转，通过高度卡尺工具测量舟骨高度。动态应激下的姿势平衡通过Biodex平衡系统进行量化，疼痛严重程度通过数值疼痛评定量表（NPRS）进行量化，残疾程度通过膝关节前疼痛量表（AKPS）进行量化。结果两组间dkv和胫骨扭转有显著性差异。DKV与疼痛（r = 0.451）、姿势平衡（r = 0.244、0.341、0.351）呈正相关，与残疾呈负相关（r = - 0.432）。胫骨扭转与失能呈负相关（r = - 0.339）。舟骨高度与测量变量无显著相关。结论慢肢生物力学，特别是DKV和胫骨扭转在女运动员的表现筛选中应优先考虑。本研究强调了将生物力学矫正策略纳入PFPS女运动员康复计划的重要性。

Objectives

To explore the effect of an isometric weighted Copenhagen adduction (WCA) exercise programme and an isometric unweighted Copenhagen adduction (CA) exercise programme on hip adduction strength, abduction strength and adduction:abduction strength ratio.

Design

Randomized controlled trial, with flat outcome structure.

Setting

Rugby training facility.

Participants

Thirty-one male rugby players.

Main outcome methods

Between-group differences in hip adduction strength, abduction strength and adduction:abduction ratio were assessed using independent-sample t-tests. Within-group differences in hip strength were assessed using paired-sample t-tests.

Results

15 participants were assigned to the CA group and sixteen to the WCA group. Post-intervention, a significant between-group difference in hip adduction:abduction strength ratio was observed (0.09 Nm/kg, p = 0.032) with large effect size (ES = 0.812). No significant between-group differences were evident for hip adduction strength (0.21 Nm/kg, p = 0.058) or hip abduction strength (0.01 Nm/kg, p = 0.856). The WCA group demonstrated significant increases in hip adduction (0.22 N/kg, +10 %, p = 0.008) and hip adduction:abduction ratio (0.06 N/kg, +7 %, p = 0.036), but not hip abduction (0.08 N/kg, +4 %, p = 0.055), following the 8-week programme. No significant changes in hip strength were observed in the CA group.

Conclusions

A low-dose 8-week adductor exercise programme using the isometric WCA exercise elicits significant increases in hip adduction:abduction strength ratio when compared to an isometric CA exercise.

目的探讨等距加权哥本哈根内收（WCA）训练方案和等距非加权哥本哈根内收（CA）训练方案对髋关节内收力量、外展力量和内收外展力量比的影响。设计随机对照试验，结果结构平坦。设置橄榄球训练设施。参与者：31名男子橄榄球运动员。主要结局方法采用独立样本t检验评估髋关节内收强度、外展强度和内收：外展比的组间差异。采用配对样本t检验评估组内髋关节力量差异。结果CA组15例，WCA组16例。干预后，组间髋关节内收外展强度比差异有统计学意义（0.09 Nm/kg, p = 0.032），且效应量较大（ES = 0.812）。髋内收强度（0.21 Nm/kg, p = 0.058）和髋外展强度（0.01 Nm/kg, p = 0.856）组间差异无统计学意义。WCA组髋关节内收显著增加（0.22 N/kg, + 10%, p = 0.008），髋关节内收：外展比显著增加（0.06 N/kg, + 7%, p = 0.036），但髋关节外展没有显著增加（0.08 N/kg, + 4%, p = 0.055）。CA组未观察到髋部力量的显著变化。结论：与等长CA训练相比，低剂量8周内收肌训练方案使用等长WCA训练可显著增加髋关节内收：外展力量比。

Objective

Establish test re-test reliability of three tests assessing hamstring function during hip extention and investigate their associations with maximal sprinting speed.

Design

Cross-sectional.

Setting

Biomechanics laboratory.

Participants

Twenty healthy, physically active men (age = 26 ± 5 years; height = 1.81 ± 0.07 m; body mass = 81 ± 7 kg).

Main outcome measures

Participants performed a maximal sprinting speed test on a non-motorised-treadmill (NMT) and three tests assessing hamstring function (hamstring scooter, hamstring push and hamstring switch), during test and re-test sessions seven days apart. Hamstring scooter peak horizontal force was measured using the NMT, while hamstring push and hamstring switch peak hip extension forces were measured using force plates (ForceDecks Lite, Vald Performance, Brisbane, Australia). We calculated each test's intraclass correlation coefficient (ICC) with 95% confidence intervals (95% CI) within (ICC_2,1) test and re-test sessions, respectively, and between (ICC_2,k) test and re-test sessions, along with Pearson's correlation coefficient (r-value) with maximal sprinting speed.

Results

Test re-test reliability ranged from moderate to excellent for all tests. The hamstring scooter was the only test with a statistically significant association (p < 0.01; r = 0.76) with maximal sprinting speed.

Conclusions

The tests described in this study all had moderate to excellent test re-test reliability, but only the hamstring scooter was associated with maximal sprinting speed.

目的建立评估髋部伸展时腘绳肌功能的三种测试方法的重测信度，并探讨其与最大冲刺速度的关系。SettingBiomechanics实验室。参与者：20名身体健康，身体活跃的男性(年龄= 26±5岁；高度= 1.81±0.07 m；体重= 81±7公斤)。在测试和重新测试期间，参与者在非机动跑步机上进行了最大短跑速度测试（NMT）和三个评估腿筋功能的测试（腿筋踏板车，腿筋推和腿筋转换），间隔7天。使用NMT测量腿筋滑板车的峰值水平力，而使用力板测量腿筋推动和腿筋切换的峰值髋部伸展力（forcedeck Lite, Vald Performance, Brisbane, Australia）。我们分别计算了（ICC2,1）次测试和再测试以及（ICC2,k）次测试和再测试之间的95%置信区间（95% CI）的每个测试的类内相关系数（ICC），以及与最大短跑速度的Pearson相关系数（r值）。结果所有测试的重测信度均为中等至优异。腿筋滑板车是唯一具有统计学显著相关性的测试(p <；0.01;R = 0.76)与最大冲刺速度有关。结论本研究所描述的测试均具有中等至优异的测试再测试信度，但只有腿筋滑板车与最大短跑速度相关。
