Hamstring strain is a common sport injury that results in pain and functional limitation. Despite its high frequency in active populations, there is no agreement regarding the best method used for early intervention of hamstring strain. The aim of the present study was to compare the effects of cryotherapy and cryostretching on clinical and functional outcomes in athletes with acute hamstring strain.
Thirty seven elite athletes with an acute grade I or II hamstring strain were randomly assigned to either cryotherapy (n = 19) or cryostretching (n = 18) group, receiving 5 sessions of supervised treatment plus home-based intervention monitored by the therapist. Pre-treatment to post-treatment changes in pain, active and passive knee extension range of motion and functional status were compared between the two groups.
Compared to cryotherapy, cryostretching resulted in larger improvement of function and passive knee extension range of motion. Changes in active knee extension range of motion and pain severity were not significantly different between the two groups.
A rehabilitation protocol involving gentle stretching following cryotherapy is more effective than cryotherapy alone in the improvement of function and passive knee range of motion in patients with grade I and II hamstring strain.
腘绳肌拉伤是一种常见的运动损伤，会导致疼痛和功能受限。尽管在活跃人群中其发生率很高，但对于腘绳肌拉伤早期干预的最佳方法尚无共识。本研究的目的是比较冷冻疗法和冷冻拉伸对急性腘绳肌拉伤运动员临床和功能结局的影响。
37名急性I级或II级腘绳肌拉伤的精英运动员被随机分为冷冻疗法组（n = 19）或冷冻拉伸组（n = 18），接受5次有监督的治疗以及由治疗师监测的家庭干预。比较两组治疗前至治疗后疼痛、主动和被动膝关节伸展活动范围以及功能状态的变化。
与冷冻疗法相比，冷冻拉伸在功能和被动膝关节伸展活动范围方面有更大改善。两组之间主动膝关节伸展活动范围和疼痛严重程度的变化无显著差异。
对于I级和II级腘绳肌拉伤患者，在冷冻疗法后进行轻柔拉伸的康复方案在改善功能和被动膝关节活动范围方面比单纯冷冻疗法更有效。
