Objective

To describe the injury rate and profiles of injuries sustained by recreational padel players, reporting time-loss and identifying player- and padel-related factors associated.

Design

Cross-sectional survey-based retrospective study.

Setting

Belgian padel clubs.

Participants

Recreational adult padel players.

Main outcome measures

Players completed a questionnaire on lifestyle factors, sports-playing practices, injuries sustained over the year and time to recovery. Injury profiles by gender and location are described. Univariate and multivariate analyses identified factors associated with an increased likelihood of injury.

Results

In total, 457 players (66.1 % men) participated, with a median age of 42 years. Overall, 167 players (36.5 %) [95 %CI 32.3; 41.1] sustained 185 injuries over the previous year with an injury rate of 2.81/1000 h playing. Median time to recovery was 30 days (IQR 15–60). Lower limb injuries were most common (53.5 %). Independent factors associated with injuries were age over 30 years, insomnia, less padel-playing experience, playing position on the right, carrying out a warm-up, using an overgrip and not playing another racket sport.

Conclusions

The incidence and profiles of padel injuries are similar to those observed in other studies. Female gender was not associated with higher injury risk. Other player- and padel-associated factors require further investigation to determine causality.

Objective

To test the relationship between quadriceps femoris (QF) strength 3 months after ACLR and long-term outcomes after ACLR.

Design

Prospective, case-cohort.

Setting

Laboratory.

Participants

51 (mean age:15.6 ± 2.2 yrs) athletes after ACLR.

Main outcome measures

1) “Early” (13.7 ± 2.1 wks) post-ACLR testing included an isokinetic QF strength assessment. 2) At medical clearance to RTS (8.4 ± 1.6 months), isokinetic QF strength, hop testing, and patient-reported outcome data were collected. Associations between early QF strength and RTS measures, as well as 2nd ACL injury in the 36 months after RTS were assessed.

Results

20 participants (39 %) sustained a 2nd ACL injury after RTS. Early QF strength limb symmetry (LSI) was moderately correlated with measures at RTS clearance (p < 0.05). Participants who failed to achieve ≥80 % QF LSI at the early testing session (23/51; 45.1 %) had 4 times higher odds (OR = 4.4; 95 %CI:1.0–19.2; p = 0.04) of sustaining a contralateral 2nd ACL injury in the 36 months following RTS clearance.

Conclusion

Early QF LSI positively associates with RTS measures. Early QF strength symmetry <80 % was associated with increased risk of contralateral ACL injury after RTS. Greater QF strength deficits early in rehabilitation may be a biomarker of poor short- and long-term outcomes after ACLR.

目的探讨ACLR术后3个月股四头肌（QF）力量与ACLR术后远期疗效的关系。DesignProspective case-cohort.SettingLaboratory。参与者：51名ACLR术后运动员（平均年龄：15.6±2.2岁）。1) aclr后“早期”（13.7±2.1周）测试包括等速QF强度评估。2)在医学清除RTS（8.4±1.6个月）时，收集等速QF强度、跳跃测试和患者报告的结局数据。评估早期QF强度与RTS措施之间的关系，以及RTS后36个月的第二次ACL损伤。结果20名参与者（39%）在RTS术后出现第二次ACL损伤。早期QF强度肢体对称性（LSI）与RTS间隙测量中度相关(p <；0.05)。在早期测试阶段未能达到≥80% QF LSI的参与者(23/51；45.1%)的几率高出4倍(OR = 4.4；95%置信区间:1.0—-19.2;p = 0.04)在RTS清除后的36个月内维持对侧第二ACL损伤的风险。结论早期QF LSI与RTS测量呈正相关。RTS术后早期QF强度对称性<； 80%与对侧ACL损伤风险增加相关。康复早期较大的QF强度缺陷可能是ACLR术后较差的短期和长期预后的生物标志物。

Objective

The Cumberland Ankle Instability Tool (CAIT) has been widely used to evaluate ankle perceived instability. The aim of this study was to determine whether infantry soldiers with and without previous ankle sprain reported different factors within the CAIT, and whether these factors are associated with physical performance.

Design

Cross-sectional study.

Settings

Military base.

Participants

Seven-hundred and nineteen male infantry soldiers aged 18–21, completed the CAIT, previous sprains questionnaire and were assessed for anthropometric and functional abilities (proprioception, dynamic balance and agility).

Main outcome measures

Factor analysis was performed on CAIT items, with Eigenvalue set to 1.5. Pearson correlations were performed between the factors extracted and the anthropometrics and functional abilities measurements, and independent T-tests were used to analyze associations between the factors and previous ankle sprains.

Results

Three factors were extracted: functional stability (factor 1), ankle rolling (factor 2) and functional performance (factor 3). Significant differences were found in participants’ self-rating on factors 1 and 2, between soldiers with and without previous sprain (p < 0.001, p < 0.001 for factors 1–2, respectively). Correlations with anthropometric and functional abilities were weak.

Conclusions

CAIT items can be clustered into three factors of perceived instability, providing military clinicians with valuable insights for targeted interventions.

目的坎伯兰踝关节不稳定工具（CAIT）被广泛应用于踝关节感知不稳定的评估。本研究的目的是确定有和没有踝关节扭伤的步兵在CAIT中是否报告了不同的因素，以及这些因素是否与身体表现有关。DesignCross-sectional研究。SettingsMilitary基地。参与者719名年龄在18-21岁的男性步兵，完成了CAIT，既往扭伤问卷调查，并评估了人体测量和功能能力（本体感觉，动态平衡和敏捷性）。主要结局指标对CAIT项目进行因子分析，特征值设为1.5。提取的因素与人体测量学和功能能力测量之间进行Pearson相关性分析，并使用独立t检验分析因素与先前踝关节扭伤之间的相关性。结果提取3个因素：功能稳定性（因子1）、踝关节滚动（因子2）和功能表现（因子3）。有和没有扭伤的士兵在因子1和因子2上的自我评定有显著差异(p <；0.001, p <；因子1-2分别为0.001)。与人体测量和功能能力的相关性较弱。结论scit项目可归为感知不稳定性的三个因素，为军队临床医生提供有针对性的干预措施提供了有价值的见解。

Objectives

In field hockey, there is limited information regarding lower extremity (LE) injury prevention screening protocols. To help inform the design of field hockey LE injury prevention screening protocols, the purpose of this study was to investigate whether static and dynamic single-leg balance (SLB), single-leg hop (SLH), and agility running tasks with unilateral limb-loading bias capture similar or different aspects of LE motor performance.

Design

Cross-sectional.

Setting

Indoor training facility.

Participants

Thirty adult female players.

Main outcome measures

For the right and left LE, Pearson's correlations (r) and the coefficient of determination (r²) assessed between-task relationships and shared variance, respectively, for: eyes-closed SLB, Star Excursion Balance Test – anterior reach, triple-hop-for-distance, 6-m-hop-for-time, modified pro-agility test.

Results

Across all correlations, 50% were not statistically-significant. Statistically-significant (P < 0.05) relationships were returned for the right LE (r = −0.69 to 0.42, r² = 0.17 to 0.48) and left LE (r = −0.62 to 0.53, r² = 0.17 to 0.38). Overall, between-task shared variance was ≤48.0%.

Conclusions

Because between-task shared variance was ≤48.0%, static and dynamic SLB, SLH, and agility running tasks with unilateral limb-loading bias each assess different aspects of LE motor performance. Therefore, practitioners should incorporate a range of LE motor performance tasks when designing field hockey LE injury prevention screening protocols.

目的在曲棍球运动中，关于下肢损伤预防筛查方案的信息有限。为了帮助曲棍球LE损伤预防筛查方案的设计，本研究的目的是调查静态和动态单腿平衡（SLB）、单腿跳跃（SLH）和单侧肢体负荷偏倚的敏捷跑步任务是否捕获了LE运动性能的相似或不同方面。室内训练设施。参与者：30名成年女性选手。主要结果测量：对于左右LE， Pearson相关系数(r)和决定系数（r2）分别评估了任务间关系和共享方差：闭眼SLB，星偏移平衡测试-前伸，三跳距离，6米跳时间，改进的前敏捷性测试。结果在所有相关性中，50%无统计学意义。统计学显著性(P <；右侧LE （r = - 0.69 ~ 0.42, r2 = 0.17 ~ 0.48）和左侧LE （r = - 0.62 ~ 0.53, r2 = 0.17 ~ 0.38）的相关性均为0.05)。总体而言，任务间共享方差≤48.0%。结论由于任务间共享方差≤48.0%，静态和动态SLB任务、SLH任务和单侧肢体负荷偏倚的敏捷跑步任务各自评估LE运动表现的不同方面。因此，从业者在设计曲棍球LE损伤预防筛查方案时应纳入一系列LE运动表现任务。

Objectives

To compare peroneal muscle quality between individuals with chronic ankle instability (CAI) and healthy controls, and to examine their relationship with ankle stability.

Design

Case-control study.

Setting

Sports Medicine research laboratory.

Methods

Sixty-five participants (35 with unilateral CAI, 30 healthy controls) were assessed. Peroneal muscle size, echogenicity, and passive stiffness were measured using ultrasound imaging and eversion strength was assessed with a hand-held dynamometer. Ankle stability was evaluated using the Y Balance Test (YBT), lateral step-down, and single-leg stance tests.

Results

Compared to controls, individuals with CAI showed significantly lower eversion strength, higher muscle echogenicity, and increased passive stiffness. In the CAI group, greater stiffness and reduced strength were associated with higher centre of pressure displacement during single-leg stance. Higher eversion strength was associated with increased YBT scores across all participants. Echogenicity was not directly associated with stability functions.

Conclusion

Deficits in peroneal muscle quality, involving echogenicity, strength and stiffness, are demonstrated in the CAI population. These factors are associated with impaired instability among CAI individuals. Interventions targeting peroneal muscle quality may improve balance and reduce the risk of recurrent ankle injuries in this population.

目的比较慢性踝关节不稳定（CAI）患者与健康对照者腓肌质量的差异，并探讨其与踝关节稳定性的关系。DesignCase-control研究。设置运动医学研究实验室。方法对65例患者（单侧CAI 35例，健康对照30例）进行评估。腓肌大小、回声性和被动僵硬度采用超声成像测量，外翻强度采用手持式测功仪评估。踝关节稳定性通过Y平衡试验（YBT）、横向降压和单腿站立试验进行评估。结果与对照组相比，CAI患者的外翻强度明显降低，肌肉回声增强，被动僵硬度增加。在CAI组中，在单腿站立时，更大的刚度和强度降低与更高的压力中心位移相关。在所有参与者中，更高的强度与更高的YBT分数相关。回声性与稳定性函数无直接关系。结论在CAI人群中存在腓骨肌质量缺陷，包括回声、力量和僵硬。这些因素与CAI患者的不稳定性受损有关。针对腓骨肌质量的干预措施可以改善平衡并降低该人群复发性踝关节损伤的风险。

The PT group exhibited greater maximal knee flexion angles during CMJNH and DJ (p = 0.02 and p = 0.02; Hedges' g = −0.92 and −1.01, respectively), along with increased knee sagittal plane range of motion across CMJNH, CMJWH, and DJ (p = 0.007, p = 0.04, and p = 0.05; Hedges' g = −1.16, −0.85, and −0.88, respectively). Additionally, the PT group demonstrated higher rates of velocity decrease during CMJWH and DJ (p = 0.015 and p = 0.005; Hedges’ g = −0.97 and −1.17, respectively).

Conclusions

This study highlighted key knee joint kinematics differences in PT athletes during jump landing. Future applications may include early detection of the pathology, before functional impairments develop.

目的探讨有或无髌骨肌腱病变排球运动员垂直起跳落地阶段的生物力学策略。设计横断面观察性研究。SettingField-based研究。研究对象：23名优秀排球运动员，其中9名有髌骨肌腱病变(PT；victoria Institute of Sport assessment -髌骨（VISA-P）评分≤80)。参与者进行了4种类型的垂直跳跃：蹲跳（SJ），无手/有手反动作跳（CMJNH/CMJWH）和落体跳（DJ）。使用惯性测量装置和力平台记录着陆生物力学。结果PT组在CMJNH和DJ时膝关节最大屈曲角度较大(p = 0.02和p = 0.02；Hedges' g分别= - 0.92和- 1.01)，以及CMJNH， CMJWH和DJ的膝关节矢状面运动范围增加(p = 0.007, p = 0.04和p = 0.05；对冲的g分别= - 1.16,- 0.85和- 0.88)。此外，PT组在CMJWH和DJ期间速度下降率更高(p = 0.015和p = 0.005；对冲的g分别= - 0.97和- 1.17)。结论本研究突出了PT运动员在起跳落地时膝关节运动学的关键差异。未来的应用可能包括在功能损伤发展之前的病理早期检测。

Objectives

Few studies have determined how individuals who undergo a second ACL reconstruction (ACLR) perform in terms of objective and patient-reported outcomes in the early rehabilitation period compared to individuals who undergo primary ACLR. This study investigated the difference in strength and functional outcomes 3–5 months postoperatively in revision ACLR patients compared to primary ACLR patients.

Design

Cross-Sectional Retrospective Chart Review.

Setting

Single university-based orthopaedic practice.

Participants

143 patients who underwent ACLR (121 primary, 22 revision)

Main outcome measures

Isokinetic knee extension and flexion strength at 60°/s and 180°/s, the IKDC, KOOS, and ACL-RSI 4.2 ± 0.7 months after ACLR.

Results

After controlling for age, sex, graft source, and time since surgery, there were no significant group differences for ACL-RSI (p = 0.771), IKDC (p = 0.950), and KOOS subscale scores (p = 0.335–0.740). Similarly, there were no significant group differences in isokinetic knee extension peak torque at 60°/s and 180°/s (p = 0.155, p = 0.147) and knee flexion peak torque 60°/s and 180°/s (p = 0.279, p = 0.325). Group LSIs were comparable for isokinetic knee extension and knee flexion.

Conclusion

Three to five months postoperatively, revision ACLR patients performed similarly in terms of thigh strength, limb symmetry, and patient-reported function compared to primary ACLR patients.

目的：很少有研究确定第二次ACL重建（ACLR）患者在早期康复期的客观表现和患者报告的结果与初次ACLR患者相比。本研究调查了改良ACLR患者与原发性ACLR患者术后3-5个月强度和功能结果的差异。设计横断面回顾性图表回顾。单一的以大学为基础的骨科实习。参与者：143例接受ACLR的患者（121例为原发性，22例为翻修）。主要结果测量：ACLR后4.2±0.7个月的IKDC、KOOS和ACL-RSI(60°/s和180°/s时的膝关节屈伸和屈曲强度。结果在控制年龄、性别、植骨来源、术后时间后，各组间ACL-RSI （p = 0.771）、IKDC （p = 0.950）、oos亚量表评分（p = 0.335 ~ 0.740）差异无统计学意义。同样，60°/s和180°/s的等速膝关节伸展峰值扭矩（p = 0.155, p = 0.147）和60°/s和180°/s的膝关节屈曲峰值扭矩（p = 0.279, p = 0.325）组间无显著差异。lsi组在等速膝关节伸展和膝关节屈曲方面具有可比性。结论：术后3 - 5个月，改良ACLR患者与原发性ACLR患者相比，在大腿力量、肢体对称性和患者报告的功能方面表现相似。

Objective

To investigate the effects of linear periodization (LP) resistance training after anterior cruciate ligament reconstruction (ACLR).

Setting

Physiotherapy clinic.

Participants

Male recreational athletes who underwent ACLR.

Main outcome measures

Knee extensor and flexor isometric strength, hop tests performance, patient-reported function (International Knee Documentation Committee, IKDC), and psychological readiness (Anterior Cruciate Ligament – Return to Sport after Injury, ACL-RSI).

Results

Twenty-two participants (mean age 27 ± 6 years) were randomized to either a LP program or the traditional '3x10 reps protocol'. The LP group demonstrated greater knee extensor strength gains compared to the 3x10 group (p = 0.03): 51 % (95 %CI, 28 to 73) vs. 26 % (95 %CI, 11 to 40). No statistically significant difference (p = 0.11) in knee flexor strength gains was observed between the LP group (45 %; 95 % CI, 18 to 71) and the 3x10 group (23 %; 95 % CI, 7 to 39). Six months after ACLR, the LP group exhibited a greater knee extensor limb symmetry index (97 ± 10 % vs. 85 ± 11 %, p < 0.01) and higher ACL-RSI scores (68 ± 18 vs. 53 ± 14, p = 0.04). No significant between-group differences were found in hop performance or IKDC scores (p > 0.05).

Conclusion

A resistance training program incorporating block-structured LP is more effective than the traditional ‘3x10 reps protocol’ in enhancing knee extensor strength and psychological readiness during ACLR rehabilitation.

目的探讨前交叉韧带重建术（ACLR）后线性周期化（LP）阻力训练的效果。SettingPhysiotherapy诊所。参与者：接受ACLR的小型休闲运动员。主要结果测量：膝关节伸屈肌等长强度、跳跃测试表现、患者报告的功能（国际膝关节文献委员会，IKDC）和心理准备（前十字韧带-损伤后恢复运动，ACL-RSI）。结果22名参与者（平均年龄27±6岁）随机分为LP方案和传统的“3x10代表方案”。与3x10组相比，LP组表现出更大的膝关节伸肌力量增加（p = 0.03）： 51% （95% CI, 28 ~ 73）对26% （95% CI, 11 ~ 40）。LP组间膝关节屈肌力量增加无统计学差异（p = 0.11） (45%；95% CI, 18 ~ 71)和3x10组(23%；95% CI, 7 ~ 39)。ACLR后6个月，LP组表现出更大的膝关节伸肌肢体对称指数(97±10%比85±11%，p <；ACL-RSI评分较高（68±18比53±14，p = 0.04）。在跳跃性能和IKDC评分方面，组间无显著差异(p >；0.05)。结论在ACLR康复过程中，结合块结构LP的阻力训练方案比传统的“3x10次方案”更有效地增强膝关节伸肌力量和心理准备。

Objective

To determine IFMs size and quality using US imaging following rehabilitation in patients with CAI.

Design

Prospective cohort study.

Settings

University Laboratory.

Participants

26 patients with CAI (age:21.9 ± 3.5 yrs; 18F, 8M) completed 8 clinician-supervised rehabilitation sessions over a 4-week period.

Main outcome measures

US imaging assessed IFM cross-sectional area (CSA) in seated and standing positions for both trained and untrained legs before and after the intervention. Muscle quality was evaluated using grey scale analysis for echogenicity.

Results

Significant (P < 0.01) increases in normalized CSA were observed for AbH and FDB in both seated and standing positions. Significant improvements (P < 0.05) were also seen in the untrained leg during standing. No significant changes were found in seated positions or in echogenicity for AbH (P = 0.26) and FDB (P = 0.052) for the trained leg.

Conclusion

IFM CSA increased post-rehabilitation, with some cross-over effects in the untrained leg. There was a certain cross-over effect observed. The muscle quality measures didn't change for the IFMs before and after rehabilitation. The IFMs strengthening should be included in CAI rehabilitation programs. There is a definite increase in size after rehabilitation. However, for quality changes there may be a need of longer rehabilitation programs.

目的利用超声显像评价CAI患者康复后ifm的大小和质量。前瞻性队列研究。SettingsUniversity实验室。参与者26例CAI患者(年龄：21.9±3.5岁；18F, 8M)在4周的时间内完成了8次临床医生监督的康复治疗。主要结果测量：在干预前后，超声成像评估了训练腿和未训练腿在坐姿和站立位置的IFM横截面积（CSA）。肌肉质量用灰阶分析评价回声性。结果：P <；坐下和站立时，AbH和FDB归一化CSA均升高0.01)。重大改进(P <；在站立时，未训练的腿也出现0.05)。训练腿的AbH （P = 0.26）和FDB （P = 0.052）的坐姿和回声性均无显著变化。结论ifm CSA在康复后增加，在未训练腿有一定的交叉效应。观察到一定的交叉效应。康复前后肌肉质量指标无明显变化。应将ifm的强化纳入CAI康复方案。康复后，尺寸明显增加。然而，对于质量的改变，可能需要更长的康复计划。
