DISABILITY OF WEIGHT SHIFT TOWARD NON-PARETIC LEG IN STROKE PATIENTS WITH NON-DOMINAT HEMISPHERE

Postural disorders seen in individuals with strokes are related to asymmetric weight bearing. However, the precise function of the dominant or non-dominant hemisphere in controlling static standing posture or bearing weight remains unclear. To examine whether there is a significant difference in the ability to balance between dominant and non-dominant hemisphere-lesioned patients, quantitative evaluation of the percentage of weight-shift was performed to determine the ability to control balance in static posture and on maximum voluntary weight-shift toward the paretic or non-paretic leg. Participants were registered from a consecutive series of stroke patients attending a rehabilitation program (n=53, male 34, female 19, 68.5±10.0 yr old). Age matched normal controls were recruited from the family of patients as volunteers (n=12, male 4, female 8, 67.9±4.9 yr old). Patients with right hemisphere lesion could not perform maximum voluntary shift weight toward the non-paretic leg, in comparison with those with dominant hemisphere lesion (p<0.05). We suggest that patients with a non-dominant lesion should practice weight shift toward the non-paretic leg to improve their static or gait balance.
