| Abstract |
INTRODUCTION
The purpose of this study was to investigate the characteristics of Sit-To-Stand(STS) movement in stroke patients according to the stroke onset time and foot positions, analyzing force, foot pressure, and muscle activities.
Many studies which investigated the characteristics of movements have not considered stroke onset time in subjects. The foot positions may influence the STS in subjects who had different stroke onset time.
METHOD
Foot pressure, force, and the activities of four muscles(Rectus Femoris, Bicpes Femoris, Tibialis Anterior, & Soleus) were measured, using Novel emed-x systems and DELSYS Trigno Wireless system. Subjects performed STS movements in three foot conditions(con1: two foots are parallel, con2: paretic limb is placed posterior to non-paretic limb, & con3: non-pareitc limb is placed posterior to paretic limb).
RESULT
Subjects who suffered from stroke within 12 months showed the maximum value of peak pressure, the minimum value of difference in vertical force between paretic and non-pareatic limb, and decrease of Rectus Femoris at paretic limb in con2.
CONCLUSION
The strategy which is the paretic limb was placed posterior to the non-paretic limb might be a helpful method for acute stroke patients. Stroke onset time within/after three years had an effect on activities of muscles. Therefore, stroke onset time might be considered in the movement study. |
