Sit-to-walk (STW) movement is a complex task characterized by starting one step before reaching a full standing posture and maintaining the body moment forward until the end of the movement. The purpose of this study was to provide an efficient interventional perspective in close proximity to daily life for improving the function of patients with chronic stroke by providing information on the positive effects of sit-to-walk training. Two patients with chronic stroke volunteered for this study. The STW training fior Subject 1 and the sit-to-stand training for Subject 2 were performed an average 30 minutes per day, 3 times a week for 4 weeks (a total of 12 sessions). Measurements included electromyographic analysis (muscle activity and onset time) on vastus medialis, bicepps femoris, tibialis anterior, and soleus, and timed up and go (TUG) test. With respect to anticipatory postural adjustments before and after training, the tibialis anterior muscle onset time of Subject 1 and 2 decreased from 1.09 to .63 seconds and from 2.46 to 1.25 seconds, respectively. In relation to multi-task performance, the TUG test with a motor task decreased by 5.90 seconds for Subject 1 and 12.03 seconds for Subject, respectively. These findings suggest that the STW training might be considered as a part of functional movement re-education close to everyday life in rehabilitation programs of stroke patients and as higher difficulty training.
