Objective : To identify the effect of symmetrical and asymmetric bilateral training For stroke
patients in upper extremity recovery.
Methods : 15 patients with stroke, randomized to an in- phase group(n =7) and anti-phase
group(n =8). Each groups received symmetrical and asymmetric bilateral training, 30-min
sessions per a day for 5 weeks, total 20 session.Accelerometer was used to evaluate the
amount used for both groups. Y-BAT was used to evaluate performance status and satisfaction,
ARAT was used to evaluate hand function.
Results : the amount used of symmetrical movement training showed significant changes in affected
and unaffected side. asymmetric bilateral training. there is a significant difference in
affected side before and after receiving asymmetric bilateral training. Also, There was a significant
difference between the groups on the affected side. Both training, there was no significant
difference in performance, satisfaction, and upper limb function between group but,
there was significant differences within-groups,
Conclusions : Symmetric training showed higher motor performance than asymmetric training,
but, To obtain a clearer difference, it would be necessary to use a neuromuscular assessment
tool such as fMRI. Also, need a clearer training protocol and the need for follow-up studies
on more stroke patients is suggested.
