Lateral ankle sprain (LAS) is one of the most common types of injury in professional football (soccer) players with high risk of recurrence. The rehabilitation after LAS in professional football players is often still time-based and relies on anecdotal experience of clinicans. There is still a lack of utilization of criteria-based rehabilitation concepts after LAS in professional football. The aims of this clinical commentary are (1) to critically discuss the need for criteria-based rehabilitation concepts after LAS in professional football players, (2) to highlight the current lack of these approaches and (3) to present a novel clinical guideline-based rehabilitation algorithm. Short time-loss (15 days) and high recurrence rate (17%) raise the question of trivialization of LAS in professional football. Despite consequences for many stakeholders involved (players, teams, clubs, insurers), there is still a lack of of criteria-based, step-by-step approaches. The use of a criteria-based rehabilitation approach might reduce the high recurrence rate after LAS in professional football players and will lead, in turn, to increased long-term player availability. Practical experiences of he authors demonstrate the feasibility of such an approach. The effectiveness of this novel rehabilitation algorithm remains to be evaluated in future studies. Level of Evidence: 5.

外侧踝关节扭伤(LAS)是职业足球运动员最常见的损伤类型之一,复发风险很高。职业足球运动员在外侧踝关节扭伤后的康复治疗通常仍以时间为基础,并依赖于临床医生的轶事经验。在职业足球运动员接受 LAS 治疗后,仍然缺乏基于标准的康复理念。这篇临床评论的目的是:(1)批判性地讨论职业足球运动员LAS术后基于标准的康复理念的必要性;(2)强调目前缺乏这些方法的现状;(3)提出一种新颖的基于临床指南的康复算法。短时间损失(15 天)和高复发率(17%)提出了职业足球运动员 LAS 无足轻重的问题。尽管这对许多利益相关者(球员、球队、俱乐部、保险公司)都有影响,但目前仍缺乏基于标准、循序渐进的方法。使用基于标准的康复方法可能会降低职业足球运动员 LAS 后的高复发率,进而提高球员的长期可用性。作者的实践经验证明了这种方法的可行性。这种新型康复算法的有效性仍有待今后的研究进行评估。证据等级:5.

Alpine skiing poses significant risks for anterior cruciate ligament (ACL) injury at both recreational and professional levels, which is compounded by high rates of re-injury. Despite the existence of return to sport (RTS) and return to snow protocols, the frequency of ACL re-injury has not been mitigated, raising doubts about protocol effectiveness. Current RTS protocols primarily focus on biomechanical and neuromuscular factors in isolation, neglecting the important perceptual-motor-cognitive changes associated with ACL injuries and the high cognitive demands of skiing. The purpose of this clinical commentary is to address the perceptual-motor-cognitive demands specific to alpine skiing, evaluate RTS testing for skiers, and propose updated standards for testing and return to snow progressions that incorporate these considerations.

高山滑雪对休闲和专业水平的前十字韧带(ACL)损伤造成了极大的风险,而再次损伤的高发率又加剧了这一风险。尽管已经制定了重返运动场(RTS)和重返雪场方案,但前十字韧带再次损伤的频率并未降低,这让人对方案的有效性产生了怀疑。目前的恢复训练方案主要关注生物力学和神经肌肉因素,而忽视了与前交叉韧带损伤相关的重要感知-运动-认知变化,以及滑雪运动对认知的高要求。本临床评论旨在探讨高山滑雪运动特有的感知-运动-认知需求,评估滑雪者的 RTS 测试,并结合这些考虑因素提出测试和重返雪场进展的最新标准:5.

Background: Reduced dorsiflexion range of motion (DFROM) which is commonly seen following lateral ankle sprain (LAS) has the potential to influence lower extremity biomechanics which have been linked to increased injury risk in the female athlete. Current research on the effect of sex and LAS history on DFROM is limited.

Hypothesis/purpose: This study had three aims 1) to determine the effect of sex, leg dominance and LAS history on DFROM, 2) to determine the effect of sex and LAS history on magnitude of DFROM symmetry and 3) to examine the association of sex on direction (whether dominant or non-dominant limb had the higher DFROM) of symmetry.

Study design: Cross-Sectional Study.

Methods: DFROM was measured bilaterally in 105 recreational athletes all participating in multidirectional sports using the tape measurement method during the weight bearing lunge test (WBLT). A mean of three measurements was used for analysis. A 3-way mixed ANOVA was carried out to determine the interaction between sex, LAS history and leg dominance on DFROM and a 2-way ANOVA for the effect of sex and LAS history on asymmetry. A chi-square test was used to determine the association of sex and direction of asymmetry.

Results: The results indicate no significant effect of sex, LAS history, and leg dominance on DFROM (p=0.65). Main effects were significant for sex and LAS on DFROM. The mean asymmetry for all participants was reported as 12.25±14.76cm. No significant effect of sex and LAS history on magnitude of asymmetry was reported. There was a significant association of sex and direction of asymmetry (χ2(1) = 11.26, p = 0.00). Sixty-five-point two percent of males were shown to have higher DFROM of their non-dominant limb compared to 75% of females who were higher in their dominant limb.

Conclusion: Findings from this study suggest that DFROM is affected by sex and LAS history. While females have increased DFROM compared to males, those with LAS history are more likely to have a decreased DFROM on the involved side. The results also indicate that interlimb asymmetries in DFROM are present in athletes, therefore practitioners should exercise caution when using bilateral comparisons in injury and return to play assessments.

Level of evidence: 2b.

背景:外侧踝关节扭伤(LAS)后常见的背屈活动范围(DFROM)减小可能会影响下肢生物力学,这与女性运动员受伤风险增加有关。假设/目的:本研究有三个目的:1)确定性别、腿部优势和外侧踝关节扭伤史对外侧踝关节扭伤的影响;2)确定性别和外侧踝关节扭伤史对外侧踝关节扭伤对称性大小的影响;3)研究性别对对称性方向(优势肢体或非优势肢体的外侧踝关节扭伤对称性更高)的相关性:研究设计:横断面研究:方法:对 105 名参加多方向运动的休闲运动员进行双侧 DFROM 测量,测量方法是在负重腾跃试验(WBLT)中使用卷尺测量法。采用三次测量的平均值进行分析。进行了三方混合方差分析,以确定性别、LAS历史和腿部优势对DFROM的交互作用,以及性别和LAS历史对不对称的影响的双向方差分析。采用卡方检验来确定性别与不对称方向的相关性:结果表明,性别、LAS历史和腿部优势对DFROM无明显影响(P=0.65)。性别和 LAS 对 DFROM 的主效应显着。所有参与者的平均不对称度为(12.25±14.76)厘米。性别和 LAS 历史对不对称程度无明显影响。性别与不对称方向有明显相关性(χ2(1) = 11.26, p = 0.00)。结果显示,65.2%的男性非优势肢体的DFROM较高,而75%的女性优势肢体的DFROM较高:本研究结果表明,DFROM受性别和LAS病史的影响。与男性相比,女性的 DFROM 增加,而那些有 LAS 病史的人更有可能患侧的 DFROM 减少。研究结果还表明,运动员肢体间的DFROM存在不对称现象,因此从业人员在进行伤病和重返赛场评估时,应谨慎使用双侧比较法。

Piriformis Syndrome (PS) is a neuromuscular condition caused by the entrapment of the sciatic nerve at the level of the piriformis muscle (PM) and can cause significant discomfort and disability. PS is often misdiagnosed due to its overlapping symptoms with other lumbar and sciatic issues and as such, diagnosing PS remains challenging despite recent invasive and non-invasive diagnostic methods. Diagnostic musculoskeletal ultrasound (MSK US) offers a non-invasive, cost-effective alternative for the identification and evaluation of PS, providing dynamic, real-time imaging of the PM and adjacent structures. This article reviews the applications, advantages, and procedural insights of MSK US in the diagnosis of PS, emphasizing its relevance in rehabilitation settings. We discuss the technical aspects of ultrasound use, interpretation of findings, and integration into clinical practice, aiming to enhance the diagnostic accuracy and therapeutic outcomes for patients with suspected PS.

梨状肌综合症(Piriformis Syndrome,PS)是一种神经肌肉疾病,由坐骨神经在梨状肌(Piriformis muscle,PM)处受压引起,可导致严重不适和残疾。由于坐骨神经痛的症状与其他腰部和坐骨神经问题重叠,因此经常被误诊,尽管最近出现了侵入性和非侵入性诊断方法,但诊断坐骨神经痛仍然具有挑战性。诊断性肌肉骨骼超声(MSK US)可为腰椎间盘突出症的鉴别和评估提供一种无创、经济有效的替代方法,它能对腰椎间盘突出症和邻近结构进行动态、实时成像。本文回顾了 MSK US 在 PS 诊断中的应用、优势和程序见解,并强调了其在康复环境中的相关性。我们讨论了超声使用的技术方面、研究结果的解释以及与临床实践的结合,旨在提高疑似 PS 患者的诊断准确性和治疗效果。

Background: Acetabular dysplasia (AD) causes pain, limited function, and development of early hip osteoarthritis. Periacetabular osteotomy (PAO) is a surgical treatment for AD that aims to reposition the acetabulum to reduce pain and improve function.

Purpose: To examine pain recovery and physical activity (PA) before and during the six months after PAO.

Study design: Case series, prospective.

Methods: Individuals with AD scheduled for PAO were enrolled. Pain intensity was evaluated before PAO and at one week and one, three, and six months following PAO. PA levels was evaluated before and six months following PAO using accelerometers (time spent in sedentary behavior, light PA, moderate-to-vigorous PA [MVPA], and daily steps) and the International Physical Activity Questionnaire (IPAQ; time spent in walking and in MVPA). Pain improvements was examined over time following PAO using a repeated-measures one-way ANOVA as well as improvements in PA levels before and six months after PAO using paired-sample t tests. In addition, time spent in MVPA was qualitatively summarized at each time point (before and six months after PAO) measured by both the accelerometers and IPAQ.

Results: Out of 49 screened participants, 28 were enrolled, and 23 individuals (22 females; age=23.1±7.9 years) completed both study visits. Compared to pre-PAO pain, participants reported significant improvements in pain at one month and onward following PAO (p<0.011). However, PA levels at six months following PAO did not differ from pre-PAO PA levels (p>0.05). Qualitatively, participants reported spending more time in MVPA recorded by the IPAQ (pre-PAO=73.3±150.2 mins/day; six-months after PAO=121.2±192.2 mins/day), compared with MVPA recorded by accelerometers (pre-PAO=22.6±25.2 mins/day; six-months after PAO=25.0±21.4 mins/day).

Conclusions: Individuals with AD reported significant pain reduction at one month and up to six months after PAO, but PA levels did not change six months after PAO compared to baseline testing. Future studies should consider examining longitudinal pain recovery and PA improvements over longer periods of time with larger samples of individuals with AD undergoing PAO and identifying modifiable factors to minimize pain and increase PA participation.

Level of evidence: III.

背景:髋臼发育不良(AD)会导致疼痛、功能受限和早期髋关节炎。髋臼周围截骨术(PAO)是一种针对髋臼发育不良的手术治疗方法,旨在重新定位髋臼以减轻疼痛并改善功能:研究设计:病例系列,前瞻性:研究设计:病例系列,前瞻性。在 PAO 前、PAO 后一周及 1、3 和 6 个月时对疼痛强度进行评估。使用加速度计(久坐时间、轻度活动时间、中强度活动时间 [MVPA] 和每日步数)和国际体力活动问卷(IPAQ;步行时间和 MVPA)对 PAO 前和 PAO 后六个月的活动水平进行评估。采用重复测量单因素方差分析研究了 PAO 后疼痛随时间的改善情况,并采用配对样本 t 检验研究了 PAO 前和 PAO 后 6 个月的 PA 水平改善情况。此外,在每个时间点(PAO 前和 PAO 后 6 个月),通过加速度计和 IPAQ 测量的 MVPA 所花费的时间也进行了定性总结:在 49 名经过筛选的参与者中,有 28 人参加了研究,其中 23 人(22 名女性;年龄=23.1±7.9 岁)完成了两次研究访问。与PAO前的疼痛相比,参与者报告PAO后一个月及以后的疼痛明显改善(p/p>0.05)。定性分析显示,与加速度计记录的MVPA(PAO前=22.6±25.2分钟/天;PAO后6个月=25.0±21.4分钟/天)相比,参与者在IPAQ记录的MVPA(PAO前=73.3±150.2分钟/天;PAO后6个月=121.2±192.2分钟/天)上花费了更多时间:结论:注意力缺失症患者在 PAO 后一个月和六个月内疼痛明显减轻,但 PAO 后六个月的水平与基线测试相比没有变化。未来的研究应考虑对接受PAO治疗的更多AD患者样本进行更长时间的纵向疼痛恢复和PA改善情况检查,并确定可改变的因素,以最大限度地减少疼痛和增加PA参与:证据等级:III。

Background: While controversy remains as to the relative benefit of operative (OM) versus non-operative management (NOM) of Achilles tendon (AT) ruptures (ATR), few studies have examined the effect on high impact maneuvers such as jumping and hopping.

Hypothesis/purpose: The purpose of this study was to determine if functional performance including strength, jumping, and hopping outcomes differed between OM and NOM of acute ATR. The secondary objective was to assess the degree of association between AT morphology and performance outcomes.

Study design: Retrospective cohort with a single prospective evaluation.

Methods: All patients were treated at an institutional secondary care center. Eligible participants (n=12 OM; 12 NOM) who were treated with OM or NOM of ATR within three weeks of injury were evaluated a minimum 20 months following ATR. AT length, thickness and gastrocnemius muscle thickness were assessed with B-mode ultrasound. Isokinetic plantar flexor strength, hop tests and countermovement and drop jumps were completed. Two-way ANOVAS were completed on all tests with unilateral values, independent t-tests were used for bilateral outcomes, and linear regressions were completed to assess the relationship between normalized AT length and performance.

Results: Affected limb AT was elongated and thickened (p<0.01), gastrocnemius was atrophied (p< 0.01) and angle-specific plantar flexor torque was reduced at 120°/s when measured at 20° plantar flexion (p = 0.028). Single leg drop vertical jump was higher in OM (p = 0.015) with no difference for hop and jump tests. AT length was related to plantar flexor torque but had no relationship with hopping performance.

Conclusions: Hop test performance was maintained despite plantarflexion weakness, gastrocnemius atrophy, and AT elongation. This may be the result of compensatory movement patterns.

背景:虽然关于跟腱(AT)断裂(ATR)的手术治疗(OM)与非手术治疗(NOM)的相对益处仍存在争议,但很少有研究对跳跃和跳跃等高冲击力动作的影响进行研究。次要目标是评估AT形态与表现结果之间的关联程度:研究设计:具有单一前瞻性评估的回顾性队列:所有患者均在一家机构的二级医疗中心接受治疗。符合条件的参与者(n=12 OM;12 NOM)在受伤后三周内接受了ATR的OM或NOM治疗,并在ATR后至少20个月接受了评估。通过 B 型超声波对 AT 长度、厚度和腓肠肌厚度进行评估。完成了等速跖屈肌力量、跳跃测试、反向运动和落跳。对所有测试的单侧值进行了双向方差分析,对双侧结果进行了独立t检验,并进行了线性回归以评估归一化AT长度与成绩之间的关系:结果:受累肢体AT变长变粗(p/Conclusions:尽管存在跖屈无力、腓肠肌萎缩和助行肌伸长,但跳跃测试的成绩仍能保持。这可能是代偿运动模式的结果。跖屈肌长度对跖屈肌力量的解释力有限,但这种关系应进一步评估:证据等级:III 级。

Introduction: Anterior Cruciate Ligament (ACL) injuries continue to be a major source of morbidity in gymnastics. The gold standard is to perform an ACL Reconstruction (ACLR). However, injuries to the proximal femoral attachment of the ACL have demonstrated an ability to regenerate. An alternative surgical intervention to the ACLR in this ACL tear subgroup is an ACL repair. The purpose of this case report is to provide a rehabilitation progression for a female gymnast after an ACL repair with Internal Brace Ligament Augmentation (IBLA).

Case description: The subject was a 16-year-old female who presented with a Sherman Type 1 proximal avulsion of her ACL. She underwent an ACL repair with IBLA. Physical therapy interventions followed a sequential and multi-phased approach based on time for tissue physiologic healing and individual progression. Patient reported outcomes including the International Knee Documentation Committee (IKDC), the Anterior Cruciate Ligament Return to Sport After Injury (ACL-RSI) and the Optimal Screening for Prediction of Referral and Outcome Yellow Flag (OSPRO-YF) were assessed in conjunction with isokinetic strength and hop performance testing to determine return to sport readiness.

Outcomes: The subject completed 42 sessions over the course of 26 weeks in addition to a home exercise program. At return to sport, clinically meaningful improvement was observed in patient reported outcomes including the IKDC, ACL-RSI, and OSPRO-YF. Additionally, strength and hop performance surpassed established thresholds of clinical significance. The subject returned to sport at six months post-operatively.

Conclusion: The subject in this case report returned to full participation in gymnastics six months after an ACL repair with internal bracing following a sequential and multi-phased rehabilitation. The primary ACL repair with IBLA appeared beneficial to this patient and could benefit from additional study in other athletes and athletic populations.

Level of evidence: Level 5.

导言:前十字韧带(ACL)损伤仍然是体操运动中的主要发病原因。金标准是进行前交叉韧带重建术(ACLR)。然而,前交叉韧带股骨近端附着处的损伤已被证明具有再生能力。在前交叉韧带撕裂亚组中,前交叉韧带修复术是替代前交叉韧带重建术的另一种手术疗法。本病例报告的目的是为一名体操女运动员提供前交叉韧带修复术(IBLA)后的康复进展情况:病例描述:患者是一名 16 岁的女性,前十字韧带谢尔曼 1 型近端撕脱。她接受了前交叉韧带修补术和 IBLA。物理治疗干预根据组织生理愈合时间和个体进展情况采取了有序、多阶段的方法。患者报告的结果包括国际膝关节文献委员会(IKDC)、前交叉韧带损伤后恢复运动(ACL-RSI)和转诊和结果黄旗预测最佳筛查(OSPRO-YF),并结合等动力量和跳跃性能测试进行评估,以确定恢复运动的准备情况:受试者在 26 周内完成了 42 次训练,此外还参加了家庭锻炼计划。在恢复运动时,患者报告的结果(包括IKDC、ACL-RSI和OSPRO-YF)均有临床意义的改善。此外,力量和跳跃表现也超过了既定的临床意义阈值。受试者在术后六个月重返运动场:结论:本病例报告中的受试者在前交叉韧带修复术后 6 个月,经过有序、多阶段的康复治疗后,完全恢复了体操运动。采用 IBLA 进行前交叉韧带初次修复似乎对该患者有益,可在其他运动员和运动人群中进行更多研究:证据等级:5 级。

Background: Secondary anterior cruciate ligament (ACL) injury is a complication of ACL reconstruction (ACLR), which may result from altered neuromuscular control affecting anticipatory postural adjustments (APAs) and compensatory postural adjustments (CPAs) required for maintaining balance during movement. However, it remains unclear how APAs and CPAs differ in single-leg landings post-ACLR compared to healthy subjects.

Purpose: The purpose of this study was to clarify the differences in muscle activities of APAs and CPAs, lower limb kinematics, and kinetics between athletes with a history of ACLR and healthy athletes during single-leg landing.

Study design: Cross-sectional study.

Methods: Eighteen female athletes were recruited and divided into ACLR (n = 9) and control groups (n = 9). The experimental task involved a single-leg landing from a 30 cm box. Joint angles and moments were determined using a 3-dimensional motion analysis system, while muscle activity was assessed using surface electromyography. Analysis intervals were divided into two phases: the APA phase (-150 ms to 50 ms) and the CPA phase (50 ms to 250 ms), with initial contact (0 ms) as the reference point. Muscle activity onset time was defined as the time when the baseline exceeded by the sum of mean values and 2 standard deviations.

Results: No significant differences were observed in muscle activity or onset time between the ACLR and control groups. However, an increased hip external rotation moment was observed during the CPA phase in the ACLR group.

Conclusion: These findings suggest that APAs and CPAs of athletes who returned to sports more than 1 year post-ACLR may be similar. The increased hip external rotation moment in the ACLR group during the CPA phase could represent a specific compensatory strategy to decrease the hip internal rotation angle post-ACLR.

Level of evidence: III.

背景:继发性前交叉韧带(ACL)损伤是前交叉韧带重建术(ACLR)的并发症之一,其原因可能是神经肌肉控制发生了改变,影响了运动过程中保持平衡所需的预期姿势调整(APA)和补偿姿势调整(CPA)。目的:本研究旨在阐明前交叉韧带损伤后运动员与健康运动员在单腿着地时,前交叉韧带损伤后运动员的前交叉韧带损伤后肌肉活动、下肢运动学和动力学方面的差异:研究设计:横断面研究:招募 18 名女运动员,分为前交叉韧带损伤组(9 人)和对照组(9 人)。实验任务包括从一个 30 厘米的箱子中单脚着地。使用三维运动分析系统测定关节角度和力矩,同时使用表面肌电图评估肌肉活动。分析间隔分为两个阶段:APA 阶段(-150 毫秒至 50 毫秒)和 CPA 阶段(50 毫秒至 250 毫秒),以初始接触(0 毫秒)为参考点。肌肉活动开始时间定义为基线超过平均值和 2 个标准差之和的时间:结果:前交叉韧带置换组和对照组的肌肉活动或开始时间没有明显差异。然而,在前交叉韧带撕裂矫正组的 CPA 阶段,观察到髋关节外旋力矩增加:这些研究结果表明,前交叉韧带修复术后一年以上恢复运动的运动员的APA和CPA可能相似。ACLR组在CPA阶段髋关节外旋力矩的增加可能是ACLR后减少髋关节内旋角的一种特殊补偿策略:证据等级:III。

Background: Single-legged hop tests have been widely used to assess performance-based outcomes after anterior cruciate ligament (ACL) reconstruction. Traditional single, triple, or 6-meter (6m) timed hop tests only measure distance or time as the principal variables, neglecting other variables, such as individual hop distances within a series of hops, flight time, and stance time. The development of portable instrumented pressure walkways has made it possible to collect parameters such as hop velocity, flight time, stance time, distance, and pressure outside of a laboratory setting. However, the reliability of instrumented pressure walkways in measuring spatial and temporal variables during single-legged hop tests is unknown. This study aimed to determine if the Zeno walkway can reliably measure spatiotemporal (ST) characteristics of hop tests.

Study design: Cross-Sectional Study.

Methods: Individuals (n=38) in this cross-sectional study performed single, triple, and 6m hop tests on a pressure-sensitive Zeno walkway. Twenty-one participants completed follow-up testing between one and 14 days later. Intraclass correlation coefficients (ICC(3,k)) were used to assess test-retest reliability of ST variables. The accuracy of vertical jump height and 6m hop timing were also measured.

Results: All ST variables demonstrated excellent test-retest reliability (ICC > 0.86) with small minimal detectable change (MDC) values during single-legged hop tests. Six-meter hop time and jump height during a bilateral drop jump were also accurately measured by the walkway.

Conclusion: An instrumented pressure walkway is a novel tool to reliably assess non-traditional parameters of clinically relevant hop and jump tests such as flight time, stance time, and jump height after lower extremity injury, surgery, and rehabilitation.

Level of evidence: 3b.

背景:单腿跳跃测试已被广泛用于评估前交叉韧带(ACL)重建后的性能结果。传统的单次、三次或 6 米计时跳跃测试仅测量距离或时间作为主要变量,而忽略了其他变量,如一系列跳跃中的单次跳跃距离、飞行时间和站立时间。便携式压力步道仪器的开发使得在实验室外收集跳跃速度、飞行时间、站立时间、距离和压力等参数成为可能。然而,在单腿跳跃测试中,压力步行道测量空间和时间变量的可靠性尚不清楚。本研究旨在确定 Zeno 步道能否可靠地测量跳跃测试的时空(ST)特征:研究设计:横断面研究:在这项横断面研究中,参与者(人数=38)在压力敏感型泽诺步道上进行了单跳、三跳和6米跳测试。21名参与者在1至14天后完成了后续测试。类内相关系数(ICC(3,k))用于评估ST变量的测试-再测可靠性。此外,还测量了垂直跳跃高度和 6 米跳计时的准确性:结果:在单腿跳跃测试中,所有 ST 变量均表现出极佳的重测可靠性(ICC > 0.86),且最小可检测变化(MDC)值较小。此外,压力步行道还能精确测量双侧下落式跳跃的六米跳跃时间和跳跃高度:带仪器的压力走道是一种新型工具,可用于可靠评估临床相关跳跃测试的非传统参数,如下肢损伤、手术和康复后的飞行时间、站立时间和跳跃高度:3b.

Effects of Low-Load Blood Flow Restriction Training on Rotator Cuff Strength and Hypertrophy: Case Series. 低负荷血流限制训练对肩袖力量和肥厚的影响:病例系列。
IF 1.6 Q3 SPORT SCIENCES Pub Date : 2024-06-01 eCollection Date: 2024-01-01 DOI: 10.26603/001c.118143

Background: The rotator cuff (RC) plays a pivotal role in the performance and health of the shoulder and upper extremity. Blood flow restriction training (BFRT) is a modality to improve strength and muscle hypertrophy with even low-load training in healthy and injured individuals. There is minimal evidence examining its effect proximal to the occluded area, and particularly on the RC.

Hypothesis & purpose: The purpose of this case series is to explore the effects of low-load BFRT on RC strength, hypertrophy, and tendon thickness in asymptomatic individuals.

Study design: Case series.

Methods: Fourteen participants with asymptomatic, untrained shoulders were recruited to participate. They performed an eight-week low-load shoulder exercise regimen where BFR was applied to the dominant arm only during exercise. The dependent variables were maximal isometric strength of the shoulder external rotators(ER) and elevators (in the scapular plane in full can position) (FC) measured via handheld dynamometry, cross sectional area (CSA) of the supraspinatus and infraspinatus muscles, and supraspinatus tendon thickness measured via ultrasound imaging (US). Mean changes within and between arms were compared after training using paired t-tests. Cohen's d was used to determine effect sizes.

Results: All participants were able to complete the BFRT regimen without adverse effects. Mean strength and CSA increased for all variables in both arms, however this increase was only significant (p<0.01) for FC strength bilaterally and CSA for the supraspinatus and infraspinatus on the BFRT side. The effect sizes for increased supraspinatus and infraspinatus CSA on the BFRT side were 0.40 (9.8% increase) and 0.46 (11.7% increase) respectively. There were no significant differences when comparing the mean changes of the BFRT side to the non-BFRT side for strength or muscle CSA. There were no significant changes to supraspinatus tendon thickness.

Conclusion: These results suggest variability in response of the RC musculature to low-load BFRT in asymptomatic individuals. The potential for a confounding systemic response in the study design makes determining whether low-load BFRT is more beneficial than low-load non-BFRT difficult. The hypertrophy seen on the BFRT side warrants further study.

Level of evidence: 4.

背景:肩袖(RC)对肩部和上肢的表现和健康起着举足轻重的作用。血流限制训练(BFRT)是一种通过低负荷训练提高健康和受伤人员力量和肌肉肥大的方法。假设与目的:本病例系列旨在探讨低负荷 BFRT 对无症状个体的 RC 力量、肥大和肌腱厚度的影响:研究设计:病例系列:研究设计:病例系列。方法:招募 14 名无症状、未接受过肩部训练的参与者。他们进行了为期八周的低负荷肩部锻炼,在锻炼过程中仅在优势臂上施加 BFR。因变量是通过手持测力计测量的肩关节外旋肌(ER)和上举肌(在肩胛平面完全可动位置)的最大等长力量(FC)、冈上肌和冈下肌的横截面积(CSA)以及通过超声波成像(US)测量的冈上肌腱厚度。使用配对 t 检验比较训练后臂内和臂间的平均变化。结果:结果:所有参与者都能完成 BFRT 训练,无不良反应。两组所有变量的平均力量和CSA均有所增加,但这种增加仅具有显著性(p/结论:这些结果表明,在无症状的个体中,RC 肌肉对低负荷 BFRT 的反应存在差异。由于研究设计中可能存在混杂的全身反应,因此很难确定低负荷 BFRT 是否比低负荷非 BFRT 更有益。BFRT侧的肥大值得进一步研究:4.
