- Abstract
[Purpose] The purpose of this study was to investigate the effect of microcurrent electrical stimulation (MES) on the recovery of muscle contraction force after muscle damage. [Subjects] The subjects of this study were 24 female Wistar rats, aged 10 weeks old. [Methods] A muscle contusion was inflicted on the left gastrocnemius muscle of all rats. After injury, the rats were divided into untreated normal recovery and MES-treated groups. MES was carried out for 30 min every day. The recovery of muscle contraction force was evaluated by measuring the ankle plantarflexion force between the 4th day and the 7th day after injury. [Results] On the 6th day after injury, the muscle contraction force of the MES-treated group was significantly higher than that of the untreated normal recovery group. [Conclusion] This result suggests that MES accelerates the recovery of muscle contraction force after muscle damage.
