Cryotherapy is often used in soft tissue sports injuries. The application of a cold pack reduces local muscular blood-flow by approximately 50% after 10 minutes. The duration of bleeding in a muscular injury is not known, but immediate application of external pressure is probably far superior in emergency treatment of an injury. Some studies have shown significant effect of cryotherapy in emergency treatment of ankle sprains, but external pressure is often applied simultaneously and the additive effect of cryotherapy is therefore uncertain. Cryotherapy reduces the metabolic rate in injured muscle and is often used several days after a soft tissue injury to reduce secondary hypoxic injury. Experimental studies, however, show no effect of cryotherapy on muscle regeneration, and no controlled clinical study has shown a significant effect in emergency treatment of soft tissue sports injuries.
冷冻疗法常用于软组织运动损伤。使用冷敷袋10分钟后，局部肌肉血流量会减少约50%。肌肉损伤的出血持续时间尚不清楚，但在损伤的紧急处理中，立即施加外部压力可能效果要好得多。一些研究表明，冷冻疗法在踝关节扭伤的紧急处理中有显著效果，但通常同时会施加外部压力，因此冷冻疗法的附加效果尚不确定。冷冻疗法可降低受伤肌肉的代谢率，常用于软组织损伤数天后，以减少继发性低氧损伤。然而，实验研究表明，冷冻疗法对肌肉再生没有影响，而且没有对照临床研究表明其在软组织运动损伤的紧急处理中有显著效果。
