ABSTRACT
Objective:
To explore the synchronization effect of whole-body
vibration therapy combined with squat-up train-ing on
ambulation of
patients with
stroke.
Method:
40
stroke survivors who could walk independently with
supervision or
assistive devices,were recruit-ed from the Department of
Rehabilitation Medicine,Huashan
Hospital Affiliated to Fudan
University(Pudong Cam-
pus)and were randomly divided into the WBVT group and the
control group.Both groups received conven-tional
rehabilitation treatment for 40 minutes per day.The WBVT group was given additional whole-body vibra-tion
therapy while squat-up
training for another 20 minutes a day.The
control group added sham stimulation of standing on the
vibration platform with no
vibration for the same amount of
time per day.At the begin-ning of enrollment and after 4 weeks intervention,participants received two times evaluation by the wearable three-dimensional
gait assessment instrument for the function of
walking,and the electromyographic signals of the
rectus femoris and long
head of the
biceps femoris were collected by
surface electromyography instrument and
statistical analysis on the data before and after the intervention.
Result:
After 4 weeks intervention,the stride speed and stride length of both groups improved siginificanlty(P＜0.05),while the WBVT group was better than the
control group(P＜0.05).The swing angle of
knee(flex-ion or extention)in the WBVT group improved significantly after intervention compared with the
control group.At the single
leg support phase(SS)of affected side,the differences were found in the synergistic contraction rate of the
rectus femoris and
biceps femoris in the bilateral
lower extremity of the WBVT group after the in-tervention(P＜0.05).At the swing phase(SW)of affected side,the differences were found in the synergistic contraction rate of the
rectus femoris and
biceps femoris in the bilateral
lower extremity between the two groups before and after the intervention(P＜0.05),but the affected side of the WBVT group was better than that the
control group after intervention(P＜0.05).
Conclusion:
Whole-body
vibration therapy combined with rhythmic squat-up synchronous
training can improve the stride speed,stride length and synergistic contraction rate of
lower limb muscles for better
ambulation of
patients with
stroke.
