Immediate effect of resisted band exercise on knee control during midstance of gait in hemiparetic patients
Abstract:
Hyperextension of the knee is one of the major causes of disturbance in the
hemiplegic gait.The aim of this study was to examine the immediate effect of resisted
band exercise on knee control during midstance of gait in hemiparetic patients.
Twenty hemiparetic patients aged between 47-66 years with a time post onset of
between 5-13 months participated in the study. All patients had knee hyperextension
during midstance. The patients were divided into control and exercise groups. Each
group consisted of ten hemiparetic patients. Both groups were similar in age, sex, type
of stroke, paretic side and time post onset.
The patients in the exercise group received knee control exercise using resisted
band for 30 minutes. This training was divided into 6 sessions, 5-minute exercise in
each session and 5-minute rest between sessions. The effect of this exercise was
evaluated by gait analysis using videography. Knee angle during midstance and gait
velocity were recorded at pre-exercise, immediately post-exercise and 30-minute postexercise.
The patients in the control group did not receive any exercise but knee angle
during midstance and gait velocity were recorded at the same time as the exercise
group.
The results of the control group showed no statistically significant differences
in knee angle and gait velocity between measurement times in the control group
(p>0.05). For the exercise group, there was a significant difference in knee angle
(p=0.032). This comparison yielded a significant difference between pre-exercise and
immediately post-exercise, immediately post-exercise and 30-minute post-exercise, and
non-significant difference between pre-exercise and 30-minute post-exercise.
Furthermore, there was no statistically significant difference in gait velocity between
measurement times in the exercise group. The improvement in knee angle in the
present study showed only short-term memory of learning. Although, the patients
could control the knee better during walking, this effect was not sufficient to improve
gait velocity.
The results of this study indicated that knee control exercise using resisted
band for 30 minutes could enhance knee control during midstance of hemiparetic gait.
However, this effect was not maintained when measured at 30-minute post-exercise
