Abstract: ObjectiveTo test the effect of visual compensation on balance function of post-stoke hemiplegic patients with the static balancer.Methods50 hemiplegic patients and 40 healthy volunteers were tested with the static balancer. Four sets of data, including load difference of the lower limbs, standard deviation of the balance center, deviation percentage, and average rebalance time under modes with eyes open or closed were collected and analyzed.ResultsThere was a significant difference in load difference of the lower limbs of hemiplegic patients between eyes open and closed modes (P<0.05), and standard deviation of the balance center, deviation percentage, and average rebalance time had more significant difference (P<0.001). There were also significant differences between data of hemiplegic patients and healthy volunteers (P<0.001).ConclusionThe effect of visual compensation on balance function of post-stoke hemiplegic patients can tested by the static balancer objectively and quantificationally.
