| Outline of Final Research Achievements |
The purpose of this study was to investigate the effect of different methods of applying neuromuscular electrical stimulation on joint contractures caused by joint fixation and unweighting the hind limbs. Performing 30 minutes of neuromuscular electrical stimulation twice a day was more effective in preventing joint contracture than performing that once a day. Performing neuromuscular electrical stimulation for 60 minutes a day was less effective in preventing joint contracture than performing that for 30 minutes a day. Therefore, it was suggested that the preventive effect of neuromuscular electrical stimulation on joint contracture may be more effective when the frequency of stimulation was increased than when the one stimulation time was extended.

| Academic Significance and Societal Importance of the Research Achievements |
臨床に即した下肢の非荷重を伴う関節固定によって生じる関節拘縮では，関節固定のみで関節拘縮と比較して骨格筋の伸張性低下が強く生じる．このため，従来の関節拘縮に対する予防方法は，過負荷となり，かえって関節拘縮を悪化する可能性がある．そこで下肢の非荷重を伴う関節固定によって生じる関節拘縮に対する予防方法を検討することは，実際の臨床における関節拘縮に対する最適な介入方法を見出すことになる．本研究により，関節拘縮の治療に要する時間が短縮化し，患者の健康寿命の延伸，医療費の削減に貢献できると考えられる．
