Nevertheless, the effects of EMS on denervation atrophy and the optimal timing for the initiation of EMS remain unclear. Objectives: This study was performed to evaluate the effects of EMS on denervated muscles in relation to the changes in myosin heavy chain (MHC) isoform, and to determine the optimal timing for EMS application. Methods: A total of 18 Sprague-Dawley rats were divided into four groups. Two treatment groups underwent a sciatic nerve crush and received EMS for 30 minutes a day, 5 days a week, for 2 weeks. EMS was initiated on post-injury day 1 for immediate EMS (IES, n=5) group and on post-injury day 15 for delayed EMS (DES, n=5) group. The denervation control (Dcon, n=4) group received identical operation without EMS. Rats in the normal control (Ncon, n=4) group did not receive either surgery or EMS. Foot print analysis using the CatWalk method, extensor postural thrust test and nerve conduction studies were also performed to assess the denervation and reinnervation process after injury. Four weeks after injury, muscle wet weight and cross- sectional area of muscle fiber were measured. MHC isoform types was analyzed in both protein homogenates and single muscle fibers. Results: Significantly lower IIx isoform and higher proportion of MHC IIb isoform in gastrocnemius muscle were observed in IES group than in Dcon group, which was not found in DES group. IES group also showed larger cross-sectional area of denervated gastrocnemius muscle fiber and lower hybrid single fiber proportion compared with DES group. Conclusions: These results indicate that immediate EMS is more effective in recovery of denervation induced MHC changes compared to the delayed EMS.Introduction 1 Material and Methods 6 Results 22 Discussion 35 Conclusion 40 References 41 Abstract in Korean 47Docto
