Abstract
The purpose of this study was to identify the effect of treadmill gradient training on lower limb muscle activity in chronic stroke patients. The subject were 32 stroke patients.. Subjects were randomly divided into three group which were control group($0^{\circ}$treadmill training(n=10)) and experimental group($5^{\circ}$treadmill training (n=10) and $10^{\circ}$treadmill training(n=12)). Three groups received treadmill gradient training for 30 minutes while 3 times per week for 6 weeks in addition to conventional physical therapy. Muscle strength was measured by EMG on rectus femoris, biceps femoris, tibialis anterior and gastrocnenius for muscle activities. In comparison of activity of rectus femoris and gastrocnemius between pre and post value, the activity of rectus femoris was significant in the experimental and control group(p<.05) and the activity of biceps femoris was significant in the $5^{\circ}$treadmill gait training group and $10^{\circ}$treadmill gait training group(p<.05). The activity of tibialis anterior was significant in the $5^{\circ}$treadmill gait training group and $10^{\circ}$treadmill gait training group(p<.05). In comparison of the difference of activity of rectus femoris among 3 groups, there was a significant difference between the $5^{\circ}$treadmill gait training group and control group(p<.05). and difference of activity of tibialis anterior was significant difference between the $10^{\circ}$treadmill gait training group and control group(p<.05). These findings suggest that $5^{\circ}$treadmill gait training group and $10^{\circ}$treadmill gait training group can be used to improve lower limb muscle activity in chronic stroke patient. In conclusion, these treadmill gradient training helped improving function of gait ability in chronic stroke patient.
