The Effect of Dual Motor Task Training while Sitting on Trunk Control Ability and Balance of Patients with Chronic Stroke

[Purpose] The purpose of this study was to investigate the effect on chronic stroke patient's trunk control and dynamic balance ability in the sitting position of a dual motor task training program combined with a conventional training program. [Subjects] Twenty-eight subjects after twelve months post stroke participated. [Methods] The subjects were randomly divided into two groups: a dual motor task training group (n=14) and a control group (n=14). Both groups performed the conventional exercise program for 60 minutes per day, 5 times a week for six weeks. The dual motor task training group also performed dual motor task training in the sitting position for 30 minutes per day, 3 times a week for six weeks at a separate place from the control group. [Results] The dual motor task training group showed significant improvements in trunk control ability, and dynamic balance in the sitting position. [Conclusion] Dual motor task training combined with a conventional exercise program improves trunk control ability and sitting balance. These results suggest that dual motor task training is feasible and beneficial for individuals with chronic stroke.
