Therapeutic ultrasound has been studied and used for the past seven decades to treat musculoskeletal injuries. Recently, a significant body of animal and human research has focused on the biomechanical effects of daily-applied, low intensity therapeutic ultrasound (LITUS) on soft tissue recovery. We performed a systematic review of the last two decades of LITUS literature to examine the effects on tendon, skeletal muscle, ligament, and tendon-bone junction injuries. LITUS facilitated tendon healing, with increased tensile strength and improved collagen alignment. For skeletal muscle and ligament injuries, LITUS increased cell proliferation during myoregeneration and improved tissue biomechanics (ultimate load, stiffness, energy absorption). LITUS aided tendon-bone junction healing through improved tissue function. Scientific evidence supports the use of LITUS to treat soft tissue injuries, and improve outcomes for musculoskeletal injuries and post-operative recovery. Lastly, we discuss the use of LITUS devices facilitating daily applied therapy in the home setting.
在过去的七十年里，人们一直在研究并使用治疗性超声来治疗肌肉骨骼损伤。最近，大量的动物和人体研究聚焦于每日应用的低强度治疗性超声（LITUS）对软组织恢复的生物力学效应。我们对过去二十年的LITUS文献进行了系统综述，以研究其对肌腱、骨骼肌、韧带和肌腱-骨连接处损伤的影响。LITUS促进了肌腱愈合，提高了拉伸强度并改善了胶原蛋白排列。对于骨骼肌和韧带损伤，LITUS在肌肉再生过程中增加了细胞增殖，并改善了组织生物力学（极限负荷、刚度、能量吸收）。LITUS通过改善组织功能辅助肌腱-骨连接处愈合。科学证据支持使用LITUS治疗软组织损伤，并改善肌肉骨骼损伤和术后恢复的结果。最后，我们讨论了LITUS设备在家庭环境中促进每日应用治疗的使用情况。
