To search the English-language literature for original research addressing the effect of cryotherapy on return to participation after injury. DATA SOURCES: We searched MEDLINE, the Physiotherapy Evidence Database, SPORT Discus, the Cochrane Reviews database, and CINAHL from 1976 to 2003 to identify randomized clinical trials of cryotherapy. Key words used were cryotherapy, return to participation, cold treatment, ice, injury, sport, edema, and pain. DATA SYNTHESIS: Original research, including outcomes-assessment measures of return to participation of injured subjects, was reviewed using the Physiotherapy Evidence Database (PEDro) Scale. Four studies were identified and reviewed by a panel of certified athletic trainers. The 4 articles' scores ranged from 2 to 4 on the PEDro scale, which has a maximum of 10 points. Two of the articles suggested that cryotherapy speeds return to participation after ankle sprains. However, these authors failed to provide in-depth statistical analysis of their results. A confounding factor of compression as part of the treatment prevented interpretation of the effects of cryotherapy in 1 article. CONCLUSIONS: After critically reviewing the literature for the effect of cryotherapy on return-to-participation measures, we conclude that cryotherapy may have a positive effect. Despite the extensive use of cryotherapy in the management of acute injury, few authors have actually examined the effect of cryotherapy alone on return-to-participation measures. The relatively poor quality of the studies reviewed is of concern. Randomized, controlled clinical studies of the effect of cryotherapy on acute injury and return to participation are needed to better elucidate the treatment responses.
检索英文文献中关于冷冻疗法对损伤后恢复运动参与影响的原创性研究。数据来源：我们检索了1976年至2003年期间的MEDLINE、物理治疗证据数据库、SPORT Discus、Cochrane系统评价数据库和CINAHL，以识别冷冻疗法的随机临床试验。使用的关键词包括冷冻疗法、恢复运动参与、冷疗、冰敷、损伤、运动、水肿和疼痛。数据综合：使用物理治疗证据数据库（PEDro）量表对包括损伤受试者恢复运动参与的结局评估指标在内的原创性研究进行了综述。由一组认证运动训练师识别并综述了四项研究。这四篇文章在PEDro量表上的得分在2至4分之间，该量表满分10分。其中两篇文章表明，冷冻疗法可加快踝关节扭伤后的恢复运动参与。然而，这些作者未能对其结果进行深入的统计分析。在一篇文章中，作为治疗一部分的加压这一混杂因素妨碍了对冷冻疗法效果的解读。结论：在严格审查了关于冷冻疗法对恢复运动参与措施影响的文献后，我们得出结论，冷冻疗法可能有积极作用。尽管冷冻疗法在急性损伤管理中广泛应用，但实际上很少有作者研究冷冻疗法单独对恢复运动参与措施的影响。所综述研究的质量相对较差令人担忧。需要进行关于冷冻疗法对急性损伤和恢复运动参与影响的随机对照临床研究，以更好地阐明治疗反应。
