Abstract:
Objective:To observe the effect of mirror visual feedback (MVF) on the motor functioning and balance of stroke survivors, and to observe any morphological and structural changes in the tibialis anterior (TA) after MVF training.Methods:Thirty-six stroke survivors were divided into a mirror group ( n=18) and a control group ( n=18). Both groups received conventional drugs and routine rehabilitation treatment, while the mirror group was additionally provided with MVF training 5 days a week for 4 weeks. Before and after the treatment, both groups were evaluated using the Fugl-Meyer assessment for the lower extremities (FMA-LE) and the Berg balance scale (BBS). Moreover, the pennation angle (PA), the muscle thickness (MT) and the fascicle length (FL) of the tibialis anterior were measured at rest and in maximum isometric voluntary contraction (MVC) using ultrasonic imaging. Results:After the treatment the average PA of the affected side at rest and the MVC of the TA increased significantly in both groups compared with before the treatment, with the average improvement in the mirror group significantly greater than in the control group. The average TA thickness at rest and the MVC were both significantly greater in the mirror group than among the control group after the treatment. The average FMA-LE and BBS scores of both groups had improved significantly, but the mirror group′s average scores were significantly better than those of the control group.Conclusion:MVF can improve the motor function and balance ability of stroke survivors. Moreover, ultrasound can be used to evaluate the changes of TA morphology in such patients quantitatively, providing an objective foundation for tracking clinical efficacy.
