Objective

To identify the prevalence of tendinopathy and describe the predictive factors of condition and chronic tendon pain in high-performance athletes.

Design

Cross-sectional observational study.

Setting

Sports training centers and competitions.

Participants

Federated high-performance athletes.

Main outcome measures

Tendinopathy and chronic tendon pain.

Results

Out of all recruited athletes, 30.6% had a confirmed diagnosis of tendinopathy. Tendinopathy prevalence was 36.5% in athletes with extremely high training exposure index (TEI), compared to 21.9% in those with low TEI (p = 0.03). There was a significant difference in the prevalence of tendinopathy sites between the sport modalities, TEI classification and sex. Almost 60% had chronic tendon pain, 48% had required a break from training, and 19% reported that the condition affected two or more tendons. Being older than 25 years (OR = 3.5; 95%CI = 2.0–6.2), female sex (OR:0.5; 95%CI:0.3–0.9) and receiving nutritional guidance (OR:1.7; 95%CI:1.3–2.4) were identified as factors associated with tendinopathy. Protection from chronic tendon pain was associated with male sex (OR:0.6; 95%CI:0.3–0.9) and nutritional guidance (OR:0.5; 95%CI:0.3–0.9).

Conclusion

This study reports the difference of tendinopathy prevalence according to sexes stratified by TEI classification. Chronic tendon pain was associated with female sex, lack of nutritional guidance, and more than three episodes of condition manifestation.

Objectives

The primary objective of the current study was to examine whether a 7-week multi-modal cervical training intervention was effective in improving sport related concussion risk factors in female varsity athletes.

Design

A quantitative experimental research design involving a prospective exercise intervention.

Methods

Seventeen female athletes (age 19.5 ± 1.42 years) attended two data collection sessions (i.e., baseline and post-testing) involving assessments in anthropometrics, isometric and dynamic neck strength, and balance control. The intervention group (n = 8) participated in a seven-week multi-modal neuromuscular training program for the cervical musculature. The control group (n = 9) was not provided with external training aside from what was performed within their sports team which was not cervical spine specific.

Results

The intervention group experienced significant improvements in neck-girth, flexor-extensor strength ratio, cervical muscular endurance, isometric and dynamic strength, and balance control.

Conclusion

The findings suggest that the intervention was effective in improving clinical measures related to concussion risk. Prior research suggests that improved size, strength, endurance, symmetry, and postural control, improve an athlete's ability to stabilize the head. This improved stability may cause athletes to have reduced motion of the head following a concussive load, consequently reducing SRC risk but should be investigated further.

Objectives

To compare maximal isometric force generation between hip adductor long-lever squeeze, the Copenhagen Adduction (CA) exercise with body-mass only, and the weighted isometric CA exercise, in rugby union players.

Design

Cross-sectional study.

Setting

Club training facility.

Participants

Forty-four male, rugby union players.

Main outcome measures

Maximum isometric hip adduction squeeze strength in the long-lever testing position, in addition to maximum isometric force data in the isometric CA exercise, and the weighted isometric CA exercise with increasing load.

Results

Significantly greater (p ≤ 0.05) torque (Nm/kg) was observed in athletes when performing a weighted isometric CA exercise with: 105% body-mass (0.22Nm/kg, +6.8%), 110% body-mass (0.44Nm/kg, +13.1%), 120% body-mass (0.80Nm/kg, +22.6%), 130% body-mass (1.16Nm/kg, +31.3%), 140% body-mass (1.58Nm/kg, +40.8%) and 150% body mass (1.96Nm/kg, +48.3%), in comparison to the isometric CA exercise, with large effect size (ES = 1.372–5.196). Significantly greater torque was also observed when compared to the isometric hip adduction long-lever squeeze exercise, with large effect size (ES = 2.022–4.091). Twenty-nine athletes reached one maximum isometric repetition in weighted isometric CAs at either 130% body-mass (n = 16) or 140% body-mass (n = 13).

Conclusions

The weighted isometric Copenhagen Adduction exercise demonstrates greater force output than the isometric CA and the long-lever squeeze.

Objectives

To report hip adduction, abduction, and adduction:abduction strength ratio values in NCAA Division I American football players, and to compare strength values across position groups.

Design

Cross-sectional study.

Setting

University training facility.

Participants

85 male football players.

Main outcome measures

Isometric hip adduction and abduction strength values in the 0° hip-flexion long-lever and 0° hip-flexion short-lever testing positions, using a ForceFrame.

Results

Hip strength values are presented across two testing positions. ANOVA revealed significant differences (p ≤ 0.05) in hip strength between position groups, with medium-to-large effect size (n² = 0.116–0.284). Skill-position and mid-position players demonstrated significantly greater hip adduction and abduction relative strength in both testing positions, when compared to lineman-position players. In addition, skill-position and mid-position players demonstrated significantly greater hip adduction:abduction strength ratios (0.19–0.20, 24–25%) in the long-lever testing position, when compared to lineman-position players, with large effect size (n² = 0.178). No significant differences in strength were observed between skill-position and mid-position players. Hip adduction:abduction strength ratios ranged from 0.68 to 0.88 in the long-lever testing position and 1.05 to 1.09 in the short-lever testing position.

Conclusion

Significant differences in relative strength exist between position groups of NCAA Division-I football players, in hip adduction, abduction and adduction:abduction ratio.

Objective

To assess differences in physical therapists’ exercise prescription and confidence in return-to-sport readiness between girl and boy patients undergoing rehabilitation post-ACLR.

Design

Cross-sectional survey.

Methods

115 physical therapist responses were collected in an electronic survey. Demographics were captured and therapists were asked to assess the appropriateness of exercises and intensity of prescription for case vignettes of an adolescent boy and girl at four different phases of post-ACLR rehabilitation. Wilcoxon signed-rank tests were performed for paired comparisons among physical therapists’ responses to the boy and girl vignettes.

Results

Physical therapists' exercise prescription and confidence in return-to-sport readiness differed for the boy and girl vignettes post-ACLR, specifically during the return-to-sport phase. When exercise was performed with perceived ideal form, physical therapists indicated it was more appropriate to maintain or progress the exercise for girls and had more confidence in girls' ability to return-to-sport. When the exercise was performed with perceived poor form, physical therapists indicated it was more appropriate to maintain or progress the exercise for boys and had more confidence in boys’ ability to return-to-sport.

Conclusion

A patient's gender may influence exercise prescription and return-to-sport expectations of physical therapists, which may contribute to disparities in patient outcomes between genders post-ACLR.

Objective

To compare center of mass (COM) and center of pressure (COP) displacement, joint angles, and muscle activity for the ankle, knee, and hip during the posteromedial (PM) reach direction of the Star Excursion Balance Test between individuals with chronic ankle instability (CAI) and healthy individuals.

Design

Cross-sectional Study.

Setting

Biomechanics laboratory.

Participants

Fifteen individuals with CAI (age: 20.0 ± 1.2 y) and 20 healthy individuals (age: 20.6 ± 0.8 y).

Main outcome measures

The maximum reach distance (MRD). The COM and COP displacement, and ankle, knee, and hip joint angles of the stance limb during the PM reach task measured via a 3D motion analysis system. Electromyography (EMG) was also recorded during the task from the tibialis anterior (TA), soleus, peroneus longus, vastus medialis (VM), biceps femoris, and gluteus medius muscles.

Results

MRD of the CAI group was shorter than the healthy group (P = 0.005). The CAI group showed higher COM positioning (P = 0.007), less knee flexion (P = 0.009), and lower muscle activity in TA (P = 0.04), and VM (P = 0.007) during performance of the PM reach as compared to the healthy group.

Conclusions

These findings suggest that individuals with CAI demonstrate altered postural control strategies during PM reach performance, likely contributing to a shorter MRD.

目的：比较慢性踝关节不稳定（CAI）患者与健康人群在Star偏移平衡测试后内侧（PM）到达方向时，踝关节、膝关节和髋关节的质心（COM）和压力中心（COP）位移、关节角度和肌肉活动度。设计：横断面研究。环境：生物力学实验室。受试者：15例CAI患者（年龄：20.0±1.2岁）和20例健康人（年龄：20.6±0.8岁）。主要观察指标：最大触达距离（MRD）。通过三维运动分析系统测量PM到达任务期间站立肢体的COM和COP位移以及踝关节，膝关节和髋关节角度。在任务期间还记录了胫骨前肌（TA）、比目鱼肌、腓长肌、股内侧肌（VM）、股二头肌和臀中肌的肌电图（EMG）。结果：CAI组的MRD短于健康组（P = 0.005）。与健康组相比，CAI组在PM到达时表现出较高的COM定位（P = 0.007），较少的膝关节屈曲（P = 0.009）， TA和VM的肌肉活动（P = 0.04）较低（P = 0.007）。结论：这些研究结果表明，CAI患者在PM到达时表现出改变的姿势控制策略，可能有助于缩短MRD。

Objectives

To provide normative values for between-limb asymmetry of hip strength and range of motion (ROM) in professional male soccer players and evaluate the relationship between these asymmetries and groin injury.

Design

Secondary analysis of a prospective cohort study.

Methods

A total of 438 professional male soccer players underwent musculoskeletal screening, injury and exposure surveillance over two consecutive seasons. Between-limb asymmetry for two hip strength (eccentric adduction and abduction) and six ROM measures were calculated, and normal asymmetry considered within 1 standard deviation (SD) of the mean. Cox proportional hazard regression analysis estimated the association between asymmetry and time-loss groin injury.

Results

Normal asymmetry ranged between 0.3% and 27.3% across strength and ROM variables. No association was found between groin injuries and asymmetry in eccentric hip adduction (HR = 0.99, 95%CI = 0.98–1.00; p = 0.167) or abduction strength (HR = 1.00, 95%CI = 0.99–1.01; p = 0.745). For five of the six ROM measures, no association with groin injuries were determined. A statistically significant, though likely clinically irrelevant, association was found between groin injury and dominant leg total hip rotation ROM (HR = 1.03, 95% CI = 1.00–1.05; p = 0.040).

Conclusion

Normal hip strength and ROM asymmetry ranged between −27 and +20%. No clinically relevant associations were found between asymmetry in hip strength or ROM and time-loss groin injuries.

目的：为职业男子足球运动员髋关节力量和活动度（ROM）的肢体间不对称提供规范性值，并评价这些不对称与腹股沟损伤的关系。设计：前瞻性队列研究的二次分析。方法：对438名职业男子足球运动员进行了连续两个赛季的肌肉骨骼筛查、损伤和暴露监测。计算两种髋关节力量（偏心内收和外展）和六种ROM测量的肢间不对称性，正常不对称性在平均值的1个标准差（SD）内考虑。Cox比例风险回归分析估计了不对称与时间损失性腹股沟损伤之间的关系。结果：在强度和ROM变量中，正常不对称范围为0.3%至27.3%。腹股沟损伤与髋偏心内收不对称无相关性(HR = 0.99, 95%CI = 0.98-1.00；p = 0.167)或外展强度(HR = 1.00, 95%CI = 0.99-1.01；p = 0.745)。对于6项ROM测量中的5项，没有确定与腹股沟损伤的关联。尽管可能与临床无关，但发现腹股沟损伤与优势腿全髋关节旋转ROM之间存在统计学意义上的关联(HR = 1.03, 95% CI = 1.00-1.05；p = 0.040)。结论：正常髋关节力量和ROM不对称范围为- 27%至+20%。未发现髋关节力量或ROM不对称与时失性腹股沟损伤之间存在临床相关性。证据等级:2;

Objectives

Explore digital technology use among recreational runners in Wales and assess attitudes toward a proposed digital intervention for running-related injury (RRI) prevention and self-management.

Design

Exploratory survey.

Setting

Online questionnaire, closed questions distributed to runners over a 7 week period.

Participants

Recreational runners living in Wales (N = 232).

Main outcome measures

Data analysed descriptively. Inferential analysis conducted via IBM SPSS v25. Pearson's Chi square and logistic regression applied to assess effects of age, sex, and weekly mileage on technology use.

Results

97% of participants reported using digital technology to monitor training, primarily through running watches (45.1%) and smartphone apps (37.6%). Pearson's chi square indicated that younger (18–24 years) and less experienced runners (3 months–2 years) were more likely to use multiple apps. Runners felt these technologies did not offer realistic advice for RRI prevention or self-management. Most runners (84.5%) were interested in the proposed intervention. Runners wanted to see injury advice, exercises to improve running and a diagnostic feature within the proposed intervention.

Conclusion

Digital technologies are widely used by recreational runners but are not perceived as useful for injury prevention/self-management. There is therefore an opportunity to develop tailored, evidence-based digital interventions for RRI prevention and self-management.

目的：探索威尔士休闲跑步者中数字技术的使用情况，并评估对拟议的跑步相关损伤（RRI）预防和自我管理的数字干预的态度。设计：探索性调查。设置：在线问卷，封闭式问题，在7周的时间内分发给跑步者。参与者：居住在威尔士的休闲跑步者（N = 232）。主要结果测量：数据描述性分析。通过IBM SPSS v25进行推理分析。运用皮尔逊卡方和逻辑回归评估年龄、性别和每周里程数对技术使用的影响。结果：97%的参与者报告使用数字技术来监控训练，主要是通过跑步手表（45.1%）和智能手机应用程序（37.6%）。皮尔逊卡方图显示，年龄较小（18-24岁）和经验不足（3个月-2岁）的跑步者更有可能使用多个应用程序。跑步者认为这些技术并没有为RRI预防或自我管理提供现实的建议。大多数跑步者（84.5%）对提议的干预感兴趣。跑步者希望在建议的干预措施中看到受伤建议、改善跑步的锻炼和诊断特征。结论：数字技术在休闲跑步者中被广泛使用，但在伤害预防/自我管理方面并不被认为是有用的。因此，有机会为RRI预防和自我管理开发量身定制的、基于证据的数字干预措施。

Objectives

To investigate the effects of different directions of athletic taping on neuromuscular control of the lower limb in recreational athletes with Achilles tendinopathy (AT).

Design

Crossover Study.

Setting

Functional assessment laboratory.

Participants

Thirty recreational athletes with AT.

Main outcome measures

Participants were randomly treated with anti-pronation taping, anti-supination taping, or no-taping. Under different taping conditions, neuromuscular tests were performed in random order: ankle proprioception Active Movement Extent Discrimination Assessment (AMEDA), Weight-Bearing Lunge Test (WBLT), single leg hop test, figure-of-eight hop test and Lower Extremity Functional Test (LEFT).

Results

Compared with no-taping, both anti-pronation taping and anti-supination taping significantly improved AMEDA proprioception test scores (p < 0.001,η_p² = 0.466), figure-of-eight hop performance (p < 0.001,η_p² = 0.307), unilateral LEFT scores (p < 0.001,η_p² = 0.448), and may reduce risk of lower limb injury in recreational athletes with AT (p < 0.001,η_p² = 0.432). Taping significantly reduced WBLT values (p < 0.001,η_p² = 0.259) but had no significant effect on single leg hop test scores (p = 0.139). Importantly, no difference between the two taping conditions was observed.

Conclusions

Both directions of athletic taping were equally effective in improving ankle proprioception, lower extremity functional performance, and reducing the risk of injury in athletes with AT, but had no significant effect on lower limb explosive strength and were associated with significantly reduced ankle dorsiflexion.

目的：探讨不同方向运动贴敷对休闲运动员跟腱病（AT）下肢神经肌肉控制的影响。设计：交叉研究。单位：功能评估实验室。实验对象：30名娱乐性AT运动员。主要结果测量：参与者随机接受抗旋前、抗旋后或无旋后治疗。在不同的贴带条件下，随机进行神经肌肉测试：踝关节本体感觉主动运动程度辨别评估（AMEDA）、负重弓步测试（WBLT）、单腿跳测试、八字跳测试和下肢功能测试（左）。结果：与未包扎相比，抗旋前和抗旋后包扎均能显著提高休闲AT运动员AMEDA本体感觉测试得分（p p2 = 0.466）、八字跳成绩（p p2 = 0.307）、单侧左肢得分（p p2 = 0.448），并可降低下肢损伤风险（p p2 = 0.432）。带带显著降低了WBLT值（p p2 = 0.259），但对单腿跳测试分数没有显著影响（p = 0.139）。重要的是，没有观察到两种胶带条件之间的差异。结论：两种方向的运动胶带在改善AT运动员的踝关节本体感觉、下肢功能表现和降低损伤风险方面同样有效，但对下肢爆发力没有显著影响，且与显著减少踝关节背屈有关。

Objective

This study aimed to investigate the current beliefs and practices among Australian physiotherapists regarding the management of anterior cruciate ligament (ACL) injuries.

Design

Cross-sectional survey.

Setting

Online survey.

Participants

Australian physiotherapists.

Outcome measures

The survey assessed beliefs and practices regarding non-operative management, ACL reconstruction, pre- and post-operative rehabilitation, and return to sport (RTS) criteria. Frequencies and percentages summarized survey responses, and chi-square or Fisher's exact tests assessed whether beliefs and practices were influenced by experience (≤6 years or >6 years) and annual caseload (<6 or ≥6 patients).

Results

In total, 419 physiotherapists were included, with 367 completing the survey in its entirety. Most physiotherapists (86.8%) consider non-surgical management alternatives for patients. Two-thirds (59.8%) recommend a minimum of 9–12 months before RTS, emphasizing recovery of knee strength (93.9%) and psychological readiness (93.9%). Of those who assessed strength, 32.5% use manual muscle testing, and 37.4% assess strength from hop testing. The 63.5% of respondents who reported barriers to implementing best practice ACL management, cited lack of resources (69.1%) and patient non-compliance (67.8%) as the most common reasons.

Conclusion

This survey of Australian physiotherapists showed alignment with evidence-based ACL guidelines but highlighted differences from international practices and variations by experience and caseload.

目的：本研究旨在探讨当前澳大利亚物理治疗师对前交叉韧带（ACL）损伤管理的信念和做法。设计：横断面调查。设置：在线调查。参与者：澳大利亚物理治疗师。结果测量：该调查评估了非手术治疗、ACL重建、术前和术后康复以及重返运动（RTS）标准的信念和做法。频率和百分比总结了调查结果，卡方检验或Fisher精确检验评估了信念和实践是否受到经验（≤6年或≤6年）和年度病例量的影响。结果：总共包括419名物理治疗师，其中367名完成了完整的调查。大多数物理治疗师（86.8%）考虑对患者进行非手术治疗。三分之二（59.8%）建议至少在RTS前9-12个月，强调膝关节力量恢复（93.9%）和心理准备（93.9%）。在评估力量的人中，32.5%使用手动肌肉测试，37.4%通过跳跃测试评估力量。63.5%的受访者报告了实施最佳ACL管理的障碍，其中最常见的原因是缺乏资源（69.1%）和患者不遵守（67.8%）。结论：这项对澳大利亚物理治疗师的调查显示与基于证据的ACL指南一致，但突出了与国际实践的差异以及经验和病例量的差异。
