A portable ankle rehabilitation robot with intelligent stretching and game-based active movement training was used to treat the spastic impaired ankle of children with cerebral palsy over six weeks. The subject's calf muscles and Achilles tendon properties were evaluated before and after treatment using ultrasonography and biomechanical measures. It was found that there were decreased Achilles tendon resting length (2.5%), increased cross-sectional area (5.5%), increased stiffness (22.9%), increased Young's modulus (13.8%), decreased soleus muscle fascicular stiffness (53.7%), and decreased medial gastrocnemius fascicular stiffness (46.1%).
使用一款具有智能伸展和基于游戏的主动运动训练功能的便携式踝关节康复机器人，对脑瘫儿童的痉挛性受损踝关节进行了为期六周的治疗。在治疗前后，采用超声检查和生物力学测量方法对受试者的小腿肌肉和跟腱特性进行了评估。结果发现，跟腱静息长度减少了2.5%，横截面积增加了5.5%，刚度增加了22.9%，杨氏模量增加了13.8%，比目鱼肌束状刚度降低了53.7%，腓肠肌内侧束状刚度降低了46.1%。
