Abstract

Context: Contusion and soft tissue injuries are common in sports. Photobiomodultion, light and laser therapy, is an effective aid to increase healing rates and improve function after various injury mechanisms. However, it is unclear how well photobiomodulation improves function after a contusion soft tissue injury. This study aimed to determine the effects of a pulsed red and blue photobiomodulation light patch on muscle function following a human thigh contusion injury.

Design: Single-blinded randomized control trial design.

Methods: We enrolled 46 healthy participants. Participants completed 5 visits on consecutive days. On the first visit, participants completed a baseline isokinetic quadriceps strength testing protocol at 60°/s and 180°/s. On the second visit, participants were struck in the rectus femoris of the anterior thigh with a tennis ball from a serving machine. Immediately following, participants were treated for 30 minutes with an active or placebo photobiomodulation patch (CareWear light patch system, CareWear Corp). Following the treatment, participants completed the same isokinetic quadriceps strength testing protocol. Participants completed the treatment and isokinetic quadriceps strength test during the following daily visits. We normalized the data by calculating the percent change from baseline. We used a mixed model analysis of covariance, with sex as a covariate, to determine the difference between treatment groups throughout the acute recovery process.

Results: We found the active photobiomodulation treatment significantly increased over the placebo group, quadriceps peak torque during the 180°/s test (P = .030), and average power during both the 60°/s (P = .041) and 180°/s (P ≤ .001) assessments. The mean peak torque and average power of 180°/s, at day 4, exceeded the baseline levels by 8.9% and 16.8%, respectively.

Conclusions: The red and blue photobiomodulation light patch improved muscle strength and power during the acute healing phase of a human thigh contusion injury model.

脉冲红蓝光生物调制治疗大腿挫伤和软组织损伤:一项随机对照试验。
背景:挫伤和软组织损伤在体育运动中很常见。光生物模块化、光和激光治疗是提高各种损伤机制后愈合率和改善功能的有效辅助手段。然而,目前尚不清楚光生物调制对挫伤性软组织损伤后功能的改善程度。本研究旨在确定脉冲红蓝光生物调制光贴片对人类大腿挫伤后肌肉功能的影响。设计:单盲随机对照试验设计。方法:我们招募了46名健康参与者。参与者连续几天完成了5次访问。在第一次访问中,参与者完成了60°/s和180°/s的基线等速股四头肌强度测试方案。在第二次访问中,参与者被发球机的网球击中大腿前股直肌。紧接着,参与者用活性或安慰剂光生物调制贴片(CareWear光贴片系统,CareWear Corp)治疗30分钟。治疗后,参与者完成了相同的等速股四头肌力量测试方案。参与者在接下来的日常访问中完成了治疗和等速股四头肌力量测试。我们通过计算与基线相比的百分比变化来归一化数据。我们使用协方差的混合模型分析,以性别为协变量,来确定整个急性恢复过程中治疗组之间的差异。结果:我们发现,与安慰剂组相比,主动光生物调制治疗显著增加,在180°/s测试期间股四头肌峰值扭矩(P=.030),在60°/s(P=.041)和180°/s(P≤.001)评估期间平均功率显著增加。在第4天,180°/s的平均峰值扭矩和平均功率分别超过基线水平8.9%和16.8%。结论:在人大腿挫伤损伤模型的急性愈合阶段,红蓝光生物调制光片提高了肌肉的力量和力量。

期刊介绍: The Journal of Sport Rehabilitation (JSR) is your source for the latest peer-reviewed research in the field of sport rehabilitation. All members of the sports-medicine team will benefit from the wealth of important information in each issue. JSR is completely devoted to the rehabilitation of sport and exercise injuries, regardless of the age, gender, sport ability, level of fitness, or health status of the participant. JSR publishes peer-reviewed original research, systematic reviews/meta-analyses, critically appraised topics (CATs), case studies/series, and technical reports that directly affect the management and rehabilitation of injuries incurred during sport-related activities, irrespective of the individual’s age, gender, sport ability, level of fitness, or health status. The journal is intended to provide an international, multidisciplinary forum to serve the needs of all members of the sports medicine team, including athletic trainers/therapists, sport physical therapists/physiotherapists, sports medicine physicians, and other health care and medical professionals.
