Abstract

When muscle is immobilised in a shortened position there is a reduction in fibre length and an increase in the proportion of connective tissue. This results in reduced muscle compliance and a loss of range of joint motion. Experiments have been carried out to determine whether short periods of stretch are effective in preventing these changes. The soleus muscle of the mouse was immobilised in a shortened position for a period of 10 days by means of a plaster cast. Every two days the cast was removed and the muscle passively stretched for a 15 minute period. It was found that this treatment prevented the connective tissue changes but did not prevent the reduction in muscle fibre length, which in itself resulted in considerable loss of range of motion.

摘要

当肌肉固定在缩短位置时,纤维长度会缩短,结缔组织的比例会增加。这会导致肌肉顺应性降低和关节活动范围减小。已经进行了实验来确定短时间的拉伸是否能有效防止这些变化。通过石膏固定将小鼠的比目鱼肌在缩短位置固定10天。每两天取下石膏,将肌肉被动拉伸15分钟。结果发现,这种治疗可防止结缔组织变化,但不能防止肌肉纤维长度缩短,而这本身就导致了相当大的活动范围丧失。
