Purpose: This study was intended to examine the effects of electroacupuncture and therapeutic exercise on muscle atrophy and exercise function in an ischemic stroke model induced by middle cerebral artery occlusion.
Methods: This study selected 120 Sprangue-Dawley rats, 8-week of age, divided them into six groups, and assigned 5 rats to each group. Experiments were conducted for 1, 3 days, 1, and 8 weeks, respectively. Group I was a group of electroacupuncture and therapeutic exercise after inducing ischemic stroke; Group II was a group of therapeutic exercise after inducing ischemic stroke; Group III was a group of electroacupuncture after inducing ischemic stroke; Group IV was a sham group of electroacupuncture after inducing ischemic stroke; Group V was a control group and Group VI was a sham group without ischemic stroke. In each group, changes in weight of muscle and relative muscle of TA muscle, neurologic motor behavior test, histologic observations were observed and analyzed.
Results: For the changes in muscle weight of unaffected and affected sides of TA muscle, muscle atrophy was seen in an affected side 3 days after ischemic stroke was induced. There was statistically significant difference in Group I 1 week and 8 weeks after ischemic stroke was induced, compared to Group V (p<0.05). For the changes in relative muscle weight of unaffected and affected sides of tibial anterior muscle, there was significant decrease in each group 3 days after ischemic stroke was induced, compared to Group IV, while there was statistically significant increase in Group I 1 week after ischemic stroke was induced, compared to Group V (p<0.05). For neuologic exercise behavior test, Group I generally had the highest score, compared to other groups.
Conclusion: electroacupuncture and therapeutic exercise may improve muscle atrophy and change in histologic observations expression of ischemic stroke rats and contribute to the improvement of exercise function.
