Purpose: The purpose of this study were how 10 effect baJance capacity to stroke patients who were taken knee exlensor
fatigue and were understood. Therapists offered the way of effective therapy to sσoke patients in clinical trials.
Methods: The subject of this study were 16 chronic sσoke pa ents (9 es ， 8 fem es) ， 16 able-bodied control nonnal people(5 males, 11 females) and their average duration of symptoms were 4.9 years at S hospital in Sungnam city. Patients average age were 55.67, health control age were 59.13. Both sσoke patient control group and able-bodied age-matched ontrol group were measured using maximal voluntary isometric contraction(MVIC) for Jeading knee extensor fatigue. Isometric contraction was run lOseconds continuously and each control was taken rest 5 seconds one time for inducing muscle fatigue. The end point was measured decreasing 3 times continuously which the value of MVIC was less 50%, and then the number of knee extensor 10 induce muscle fatigue, posi on sense, and balance and gait capability were measured after taking knee extensor fatigue.
Results: There was a significantly differεnces that Stroke patients group was shown that the paretic side knee extensor fatigue was represented faster than health control group (p
Conclusion: Therefore, localized muscle fatigue by gaiting abnonnal gait pattem to chronic sσoke patient was affected the
disability of balance capacity. And abnonnal gait pattem was brought secondly increasing number of falling down. These
factors were considered to stroke rehabilitation.
