A Pilot Study on the Effect of Functional Electrical Stimulation of Stroke Patients in a Sitting Position on Balance and Activities of Daily Living

[Purpose] This study investigated the effect of functional electrical stimulation (FES) of stroke patients in a sitting position on balance and activities of daily living. [Methods] FES was applied to stroke patients (six male, three female) while in a sitting and supine position. FES was applied six times for 30 minutes each for a total of six weeks. [Results] The timed up and go (TUG) values at weeks 2, 4, and 6 after FES treatment in a sitting position were noticeably decreased in a time-dependent manner, compared with controls. In the sitting, the functional reach test (FRT) values were significantly increased in a time-dependent manner. The same values in the supine position weakly showed a similar pattern to those in the sitting position. Furthermore, the functional independent measurement (FIM) values in the sitting position were markedly increased in a time-dependent manner. In the sitting position, the intensity of FES was markedly decreased in a time-dependent manner. The same values in the supine position weakly showed a similar pattern to those in the sitting position. [Conclusion] These results suggest that the conditions of stroke patients in both the sitting and supine positions after FES treatment were improved and that FES had a greater effect in the sitting position.
