| Abstract: | [Purpose] The purpose of this study was to access the effect of weight bearing exercise(treadmill exercise) and non-weight-bearing exercise (swimming exercise) on gait in therecovery process after a sciatic nerve crush injury. [Subjects and Methods] Rats wererandomly divided into a swimming group (n=3) with non-weight-bearing exercise after asciatic nerve crush and a treadmill group (n=3) with weight bearing exercise after asciatic nerve crush. Dartfish is a program that can analyze and interpret motion throughvideo images. The knee lateral epicondyle, lateral malleolus, and metatarsophalangealjoint of the fifth toe were marked by black dots before recording. [Results] There weresignificant differences in TOK (knee angle toe off) and ICK (knee angle at initialcontact) in the swimming group and in TOK, ICA (ankle angle at initial contact), and ICKin the treadmill group. In comparison between groups, there were significant differencesin TOA (ankle angle in toe off) and ICA at the 7th day. [Conclusion] There was nodifference between weight bearing and non-weight-bearing exercise in sciatic nerve damage,and both exercises accelerated the recovery process in this study.Key words: Sciatic nerve crush injury, Weight-bearing exercise, Gait |
