Objectives

To evaluate the prevalence of tendon, bone, and joint pain, and to examine the physical features associated with pain, in young artistic, acrobatic, and rhythmic female gymnasts.

Design

Cross-sectional.

Participants

274 gymnasts, aged 9–16 years.

Main outcome

All gymnasts were clinically assessed for joint, bone, and tendon pain and for training-impact, anthropometric-measures, bone-properties, muscle-strength, and joint range-of-motion (ROM).

Results

Pain was identified in 69.7 % of the participants. Artistic gymnasts suffered a higher prevalence of tendon and bone pain compared to rhythmic gymnasts (p = 0.011 and p = 0.005, respectively). Logistic-regression showed that greater BMI% and lower plantar-flexor strength were associated with tendon pain; greater BMI%, increased age, menarche, reduced tibial-strength, and reduced muscle strength with bone pain; and, increased age, reduced muscle strength and increased ROM with joint pain (p < 0.05). A reduced risk of tendon and joint pain was found in rhythmic and acrobatic gymnasts compared to artistic gymnasts, and reduced risk of bone pain when practicing rhythmic gymnastics compared to artistic gymnastics (p < 0.05).

Conclusions

Young female gymnasts are at a high risk of developing pain during training. Physical features are specific to pain categories and to gymnastics disciplines. Clinically, young gymnasts should be routinely screened for physical features and for injuries.

目的评估年轻艺术、杂技和艺术体操女运动员肌腱、骨和关节疼痛的患病率，并检查与疼痛相关的身体特征。参与者：体操运动员274名，年龄9-16岁。所有体操运动员的关节、骨骼和肌腱疼痛以及训练影响、人体测量、骨骼特性、肌肉力量和关节活动范围（ROM）均进行了临床评估。结果69.7%的参与者有西班牙症状。与艺术体操运动员相比，艺术体操运动员的肌腱和骨骼疼痛发生率更高（p = 0.011和p = 0.005）。logistic回归分析显示，较高的BMI%和较低的跖屈肌强度与肌腱疼痛有关；BMI%升高、年龄增加、月经初潮、胫骨力量减弱、肌肉力量减弱并伴有骨痛；随着年龄的增长，肌肉力量减少，关节疼痛增加(p <；0.05)。与艺术体操运动员相比，艺术体操运动员和杂技体操运动员的肌腱和关节疼痛风险降低，与艺术体操运动员相比，练习艺术体操运动员的骨骼疼痛风险降低(p <；0.05)。结论年轻女体操运动员在训练过程中出现疼痛的风险较高。身体特征是特定于疼痛类别和体操学科的。在临床上，年轻的体操运动员应该定期进行身体特征和损伤的筛查。

Objectives

To compare postural control between people with and without patellofemoral pain (PFP) during the Star Excursion Balance Test (SEBT), single-legged stance, single-legged squat, and single-legged landing tasks.

Design

Cross-sectional.

Settings

Laboratory.

Participants

Forty-four participants (22 with PFP and 22 controls).

Main outcomes measures

Postural control was evaluated by measuring reach distance in three directions during the SEBT, and center of pressure (CoP) behavior during the single-legged tasks.

Results

The PFP group demonstrated a larger CoP ellipse area during the single-legged squat (effect size [ES] = 0.82, p < 0.01) and landing tasks (ES = 0.70, p < 0.05) compared to controls. Additionally, the PFP group showed alterations in anteroposterior CoP behavior during the single-legged squat compared to controls, including increased displacement (ES = 0.78, p < 0.01), trajectory length (ES = 0.62, p < 0.05), and velocity (ES = 0.61, p < 0.03). No significant differences were found between groups for any distance in the SEBT or for CoP variables during the single-legged stance.

Conclusions

People with PFP exhibit postural control alterations during more dynamic tasks, such as single-legged squats and landings. However, no alteration during static tasks like single-leg stance or during any SEBT direction were observed.

目的比较髌骨痛（PFP）患者和非PFP患者在进行星偏移平衡测试（SEBT）、单腿站立、单腿深蹲和单腿着地任务时的姿势控制情况。参与者：44名参与者（22名PFP患者和22名对照组）。主要结果测量：通过测量SEBT期间三个方向的到达距离和单腿任务期间的压力中心（CoP）行为来评估姿势控制。结果PFP组在单腿深蹲时CoP椭圆面积更大(效应量[ES] = 0.82, p <；0.01)和着陆任务(ES = 0.70, p <；0.05)。此外，与对照组相比，PFP组在单腿深蹲时的前后位CoP行为发生了变化，包括位移增加(ES = 0.78, p <；0.01)，弹道长度(ES = 0.62, p <；0.05)，速度(ES = 0.61, p <；0.03)。在单腿站立时，两组之间SEBT的任何距离或CoP变量均无显著差异。结论：PFP患者在进行动态动作时，如单腿深蹲和落地时，会出现姿势控制的改变。然而，在静态任务中，如单腿站立或在任何SEBT方向，没有观察到变化。

Objectives

To evaluate the correlation between the Landing Error Scoring System (LESS) and single leg squat (SLS) in assessing neuromuscular control deficits in Reserve Officers' Training Corps (ROTC) Cadets.

Design

Cross-sectional observational study.

Setting

University gymnasium.

Participants

Fifty-six ROTC members (Age, 20.16 ± 1.7 years; sex, 20 females, 36 males; height, 68.78 ± 3.32 inches; mass, 73.65 ± 12.98 kg; dominant limb length; 89.83 ± 5.1 cm) completed 3 jump-landings and 5 SLS trials.

Main outcome measures

The jump-landing and SLS were recorded using PhysiMax markerless motion capture, and errors in the frontal and sagittal planes were automatically graded on a dichotomous scale.

Results

Average LESS scores were 5.36 ± 2.93 errors, while SLS errors were 3.93 ± 1.03 (left) and 4.30 ± 1.73 errors (right). No significant associations were found between LESS and SLS errors, including medial knee displacement errors in frontal plane or any sagittal plane errors.

Conclusions

The LESS and SLS likely capture different aspects of neuromuscular control due to task differences. Clinicians should utilize both screening methods to identify high-risk movements.

目的评价着陆失误评分系统（LESS）与单腿深蹲（SLS）在评价后备军官训练团（ROTC）学员神经肌肉控制缺陷中的相关性。设计横断面观察性研究。SettingUniversity体育馆。参与者：56名后备军官训练团成员(年龄：20.16±1.7岁；性别：女性20人，男性36人；高度：68.78±3.32英寸；质量：73.65±12.98 kg；优势肢长；89.83±5.1 cm)完成3次起跳和5次SLS试验。使用PhysiMax无标记运动捕捉记录跳跃着陆和SLS，并根据二分类量表自动分级额、矢状面误差。结果LESS评分的平均误差为5.36±2.93，SLS评分的平均误差为3.93±1.03（左）和4.30±1.73（右）。在LESS和SLS误差之间没有发现显著的关联，包括膝关节内侧在额位面或任何矢状面位移误差。结论由于任务差异，LESS和SLS可能捕获了神经肌肉控制的不同方面。临床医生应利用这两种筛查方法来识别高危运动。

Objectives

To examine differences in psychological readiness and self-reported function based on pre-operative risk factors at time of return to sport (RTS) after adolescent shoulder stabilization. Our secondary purpose was to assess the relationship between pre-operative shoulder instability history and psychological readiness at time of RTS testing.

Design

Multi center retrospective cross-sectional study.

Setting

Pediatric hospital.

Participants

52 participants (65 % male; 16.5 ± 1.3 years old; 5.9 ± 1.0 months post-surgery).

Main outcome measures

Shoulder Instability Return to Sport after Injury scale (SI-RSI), Quick-Disabilities of Arm, Shoulder, Hand (QuickDASH), number of pre-operative instability episodes.

Results

Median SI-RSI score was 75.4 IQR (62.5–88.3) at time of RTS testing. Females reported significantly lower SI-RSI scores compared to males (65.0, IQR: 50.9–79.2 vs 77.9, IQR: 65.7–90.1; p = 0.034). There were no significant differences in SI-RSI scores in patients with greater than 3 instability events compared to patients with 1 or 2 instability events (p = 0.866). SI-RSI and QuickDASH scores displayed a moderate negative correlation (r = −0.51, p = 0.001).

Conclusion

Males and females after shoulder stabilization surgery report differences in psychological readiness at time of RTS. Pre-operative instability history was not related to SI-RSI scores at time of RTS testing, but SI-RSI scores are related to subjective function.

目的探讨青少年肩部稳定术后重返运动（RTS）时基于术前危险因素的心理准备和自我报告功能的差异。我们的第二个目的是评估术前肩部不稳定史与RTS测试时的心理准备之间的关系。设计：多中心回顾性横断面研究。SettingPediatric医院。参与者：52名参与者(65%男性；16.5±1.3岁；术后5.9±1.0个月)。主要观察指标：肩不稳定性损伤后恢复运动量表（SI-RSI），臂、肩、手快速失能（QuickDASH），术前不稳定性发作次数。结果RTS测试时SI-RSI评分中位数为75.4 IQR（62.5-88.3）。女性报告的SI-RSI得分明显低于男性(65.0,IQR: 50.9-79.2 vs 77.9, IQR: 65.7-90.1；p = 0.034)。不稳定事件大于3次的患者与不稳定事件1次或2次的患者相比，SI-RSI评分无显著差异（p = 0.866）。SI-RSI与QuickDASH评分呈中度负相关（r = - 0.51, p = 0.001）。结论肩关节稳定手术后男性和女性在RTS时的心理准备存在差异。术前不稳定史与RTS测试时的SI-RSI评分无关，但SI-RSI评分与主观功能有关。

Objective

Evaluate the efficacy of blood flow restriction training (BFRT) in people with knee conditions.

Methods

We searched Medline, Web of Science, and Sport DISCUS from inception until October 2023, seeking randomised controlled trials (RCTs) involving participants with any knee condition and BFRT in at least one intervention arm. We used a random-effects model meta-analysis to pool methodologically homogeneous data and the Grading of Recommendations, Assessment, Development, and Evaluations approach to categorise certainty of evidence.

Results

15 RCTs involving 418 participants were eligible, investigating people post-anterior cruciate ligament reconstruction (n = 7) and cartilage surgery (n = 2), or with knee osteoarthritis (n = 3) and patellofemoral pain (n = 3). There is very low certainty evidence that adding BFRT to resistance training is superior to resistance training for pain outcomes (small SMD 0.47, 95 % CI 0.09, 0.85). There is very low certainty evidence that adding BFRT to resistance training is equivalent to resistance training for function and strength outcomes.

Conclusions

BFRT offers a significant effect on short-term pain that is of questionable clinical relevance, and no significant effects on function or quadriceps strength. Future high-quality RCTs are required to appropriately explore clinical efficacy, and clinicians should exercise caution in offering BFRT to people with knee conditions.

目的评价血流量限制训练（BFRT）对膝关节疾病患者的治疗效果。方法：我们检索了Medline、Web of Science和Sport DISCUS从成立到2023年10月，寻找随机对照试验（RCTs），涉及至少一个干预组中任何膝关节状况和BFRT的参与者。我们使用随机效应模型荟萃分析来汇集方法学上同质的数据，并使用推荐、评估、发展和评估分级方法来对证据的确定性进行分类。结果15项随机对照试验纳入418名受试者，调查了前交叉韧带重建（n = 7）和软骨手术（n = 2），或膝关节骨关节炎（n = 3）和髌骨股痛（n = 3）患者。有非常低的确定性证据表明，在阻力训练中加入BFRT比阻力训练更能改善疼痛结局（小SMD 0.47, 95% CI 0.09, 0.85）。有非常低的确定性证据表明，在阻力训练中加入BFRT与在功能和力量方面的阻力训练是等同的。结论sbfrt对短期疼痛有显著影响，但临床相关性尚存疑问，对功能或股四头肌力量无显著影响。未来需要高质量的随机对照试验来适当地探索临床疗效，临床医生在为膝关节疾病患者提供BFRT时应谨慎行事。

Objectives

The aim of this study was to compare intrinsic foot muscle activity during single-leg standing and single-leg drop landing between participants with and without chronic ankle instability.

Design

A cross-sectional study.

Setting

Laboratory.

Participants

Twelve participants with chronic ankle instability and eleven control participants.

Main outcome measures

The main outcomes were the muscle activities of the abductor hallucis, abductor digiti minimi, peroneus longus, and soleus muscles and the center of pressure during single-leg standing and single-leg drop landing.

Results

Participants with chronic ankle stability showed increased soleus muscle activity during single-leg standing with eyes closed and after single-led drop landing compared with that of controls. In the chronic ankle instability group, lower Cumberland Ankle Instability Tool scores were associated with reduced abductor digit minimi muscle activity during landing. No significant differences were found in other outcomes.

Conclusions

Reduced abductor digit minimi muscle activity may be associated with greater severity of chronic ankle instability. Increased soleus muscle activity in individuals with chronic ankle instability may serve as a compensatory mechanism for other impairments during single-leg standing with eyes closed and single-leg drop landing tasks.

目的本研究的目的是比较有和没有慢性踝关节不稳定的参与者在单腿站立和单腿落地时的内在足部肌肉活动。设计：横断面研究：12名慢性踝关节不稳定患者和11名对照患者。主要观察指标为单腿站立和单腿落点时外展幻觉肌、小指外展肌、腓骨长肌和比目鱼肌的肌肉活动和压力中心。结果与对照组相比，慢性踝关节稳定性患者在闭眼单腿站立和单导落下后比目鱼肌活动增加。在慢性踝关节不稳定组中，较低的Cumberland踝关节不稳定工具评分与着落时外展手指最小肌活动减少有关。其他结果无显著差异。结论外展趾小肌活动减少可能与慢性踝关节不稳定的严重程度有关。慢性踝关节不稳定患者的比目鱼肌活动增加可能作为闭眼单腿站立和单腿落地任务中其他损伤的代偿机制。

Objectives

1) Determine the relationship between neurocognitive performance and single-limb landing biomechanics 2.) Compare neurocognitive performance between individuals with anterior cruciate ligament reconstruction (ACLR) and uninjured controls.

Design

Cross-Sectional.

Setting

Laboratory.

Participants

Eighteen participants with ACLR and 18 matched uninjured controls.

Main outcome measures

Immediate Post-Concussion Assessment and Cognitive Testing: Visual Memory, Visual-Motor and Reaction Time Composite Scores. Single-limb landing biomechanics: peak knee flexion angles, peak internal knee adduction moments, and peak ground reaction forces.

Results

There were no statistically significant correlations between neurocognitive performance and single-limb landing biomechanics. Individuals with ACLR and uninjured controls exhibited similar neurocognitive performance (all p > .05).

Conclusions

The lack of associations between single-limb landing biomechanics and neurocognitive performance may suggest that computerized neurocognitive assessments are not sensitive enough to identify individuals demonstrating biomechanical loading patterns associated with ACL injury. Neurocognitive-motor assessments that specifically challenge knee motor control may be more appropriate to discern high and low neurocognitive profiles.

目的：研究神经认知能力与单肢着地生物力学的关系。比较前交叉韧带重建（ACLR）患者与未受伤对照组的神经认知表现。参与者：18名患有ACLR的参与者和18名未受伤的对照组。主要结果测量：脑震荡后立即评估和认知测试：视觉记忆、视觉运动和反应时间综合评分。单肢着地生物力学：膝关节屈曲角峰值、膝关节内收力矩峰值和地面反作用力峰值。结果神经认知能力与单肢着地生物力学性能之间无统计学意义。患有ACLR的个体和未受伤的对照组表现出相似的神经认知表现(所有p >；. 05)。结论：单肢着地生物力学与神经认知表现之间缺乏相关性，这可能表明计算机化神经认知评估不够敏感，无法识别与前交叉韧带损伤相关的生物力学负荷模式。神经认知-运动评估，特别是挑战膝关节运动控制可能更适合辨别高和低神经认知概况。

Objectives

To examine sport-specific adaptations and the influence of stroke specialization on the shoulder complex among adolescent competitive swimmers.

Design

Cross-sectional study.

Setting

Athletic facilities.

Participants

76 adolescents (14.3 ± 1.3 years), including 28 non-swimmers (Control Group, CG) and 48 competitive swimmers (Swimmers Group, SWG).

Main outcome measures

Strength of glenohumeral (GH) and scapular muscles (SM), GH joint mobility (GH ROMs), proprioception, pectoralis minor length (PML), and posterior shoulder tightness (PST) were evaluated. The Kerlan-Jobe Orthopaedic Clinic (KJOC) Score was used to evaluate shoulder function in the SWG. A tested shoulder physical performance parameters were compared between the groups.

Results

Comparisons showed that all GH, SM strength measures and PML were higher in the SWG (p < 0.05). GH ER/IR ratio was lower in SWG (MD = 0.8–0.11 N, p < 0.05). GH ROM comparisons revealed decreased IR and increased ER and total rotational ROM in the SWG (p < 0.05). No differences in proprioception or PST were found (p > 0.05). Additionally, no significant differences were observed when all parameters were compared among SWG subgroups based on stroke specialization (p > 0.05).

Conclusions

Adolescent competitive swimmers exhibited sport-specific, but not stroke-specific, adaptations in the shoulder complex.

目的探讨青少年竞技游泳运动员的运动适应性及卒中专业化对肩部复合体的影响。DesignCross-sectional研究。SettingAthletic设施。参与者76名青少年（14.3±1.3岁），其中非游泳者28人（对照组，CG），竞技游泳者48人（游泳者组，SWG）。主要观察指标：评估肱骨肩胛肌（GH）和肩胛肌（SM）的强度、肩胛肌关节活动度（GH ROMs）、本体感觉、胸小肌长度（PML）和后肩紧度（PST）。采用Kerlan-Jobe骨科临床评分（KJOC）评估SWG患者的肩关节功能。比较两组间测试的肩部物理性能参数。结果SWG组GH、SM强度指标和PML均高于对照组(p <；0.05)。SWG组GH ER/IR比较低(MD = 0.8-0.11 N, p <；0.05)。GH ROM比较显示，SWG的IR降低，ER和总旋转ROM增加(p <；0.05)。本体感觉和PST未见差异(p >；0.05)。此外，在基于脑卒中专门化的SWG亚组之间比较所有参数时，没有观察到显著差异(p >；0.05)。结论：青少年竞技游泳运动员在肩部复合体上表现出运动特异性的适应性，而不是泳姿特异性的适应性。

Objectives

To investigate the validity of a novel method for assessing intra-foot proprioception impaired by chronic ankle instability (CAI) and its association with perceived ankle instability, and to include a conventional joint position reproduction (JPR).

Design

Case-control study.

Setting

University laboratory.

Participants

Eleven controls and 19 individuals with CAI.

Main outcome measures

A circumduction reproduction test was developed to evaluate proprioception by measuring absolute errors between eyes-opened and closed conditions during ankle circumduction movement, consisting of inversion and eversion phases. Errors in hallux marker trajectory and intra-foot joint relative angles were analyzed. Additionally, the JPR was administered to comparison with the novel method.

Results

During the eversion phase, the CAI group had significantly more errors in the X and Y component than the control group. The Pearson's r between the X component and IdFAI was 0.354 (p = 0.054). The X component correlated with the movement of the rearfoot, midfoot and forefoot, with correlations of r > 0.4. However, the JPR did not detect differences between two groups (p > 0.05).

Conclusions

The circumduction reproduction test has discriminant validity for distinguishing between two groups and may provide an advantage over JPR.

Objectives

To compare the effect of a newly conceived daily injury prevention programme with FIFA11+ on injury incidence and severity in academy football players.

Design

Randomised controlled trial.

Setting

Football academy.

Participants

Ninety-three male academy football players were randomly assigned to either the control group (FIFA11+ or FIFA11+ Kids) or the intervention group (new injury prevention programme).

Main outcome measures

Injury incidence rate (per 1000 hours) and severity (days lost).

Results

Over 6 months, the control group recorded 45 injuries (incidence rate = 9.07/1000 hours), while the intervention group recorded 50 injuries (incidence rate = 10.10/1000 hours). The median number of days lost was 16 [95% confidence interval: 11, 27] in the control group and 15 [95% confidence interval: 7, 23] in the intervention group. No significant differences were found in injury incidence or severity between the two groups.

Conclusions

The newly conceived injury prevention programme was as effective as the FIFA11+ in reducing injury incidence and severity, thus representing an easy-to-implement injury prevention programme for football academies.

Trial registration

The trial was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12623000359639) retrospectively, as it was initially conducted for academic purposes, negating the requirement for prospective registration.

目的比较新设计的每日损伤预防方案与FIFA11+对青训足球运动员损伤发生率和严重程度的影响。随机对照试验。SettingFootball学院。93名男子足球运动员被随机分配到对照组（FIFA11+或FIFA11+儿童）或干预组（新伤害预防计划）。主要结局指标：伤害发生率（每1000小时）和严重程度（损失天数）。结果6个月内，对照组发生损伤45例（发生率为9.07/1000小时），干预组发生损伤50例（发生率为10.10/1000小时）。对照组损失天数中位数为16天[95%可信区间：11,27]，干预组损失天数中位数为15天[95%可信区间：7,23]。两组间损伤发生率和严重程度无显著差异。结论新设计的伤害预防方案在降低伤害发生率和严重程度方面与国际足联11+一样有效，因此代表了一种易于实施的足球院校伤害预防方案。试验注册该试验回顾性地在澳大利亚新西兰临床试验登记处注册（ACTRN12623000359639），因为它最初是为了学术目的而进行的，否定了前瞻性注册的要求。
