Outline of Final Research Achievements

This study aimed to establish a new therapeutic approach for patients being treated with immobilization and orthosis through investigation that the effects of muscle contraction induced by lumbar magnetic stimulation and neuromuscular electric stimulation on immobilization-induced limited ROM and skeletal muscle fibrosis in rat soleus muscle.
As results, isometric twitch contraction via lumbar magnetic stimulation and neuromuscular electric stimulation decreased skeletal fibrosis fibrosis and reduced the progression of ROM loss. By contrast, the effect of tetanic contraction for fibrosis and progression of ROM loss was insufficient. We believe that isometric twitch contraction via lumbar magnetic stimulation and neuromuscular electric stimulation holds potential as a new therapeutic approach for immobilization-induced loss of ROM.
