To investigate the effect of visual feedback with mental practice on symmetrical weight-bearing training in three individuals with hemiparetic stroke.
A single-subject experimental design, alternating with multiple baselines across individuals.
Laboratory of a department of occupational therapy.
Three individuals with left hemiparesis from stroke.
Visual feedback with mental practice on symmetrical weight-bearing training.
The proportion of the participant's weight-bearing by the affected limb while standing was measured using Limloader.
For participants 1, 2 and 3, the respective average weight-bearing proportions of the affected limb were 27%, 31% and 21% at baseline, 47%, 48% and 47% after visual feedback with mental practice, and 42%, 48% and 42% after visual feedback only, immediately following each training session. When the participants had visual feedback with mental practice, they placed a greater proportion of their weight on the affected limb, and this effect was maintained for 1 h.
These findings indicate that the visual feedback approach alone can effect improvement but visual feedback together with mental practice produces further positive effect on improving and maintaining a symmetrical stance posture in people with hemiparetic stroke.
探讨视觉反馈结合心理练习对三名偏瘫性脑卒中患者进行对称负重训练的效果。
单受试者实验设计，个体间采用多基线交替。
一个职业治疗科的实验室。
三名脑卒中后左侧偏瘫患者。
对称负重训练中的视觉反馈结合心理练习。
使用Limloader测量参与者站立时患侧肢体的负重比例。
对于参与者1、2和3，在每次训练 session 后立即测量，基线时患侧肢体各自的平均负重比例分别为27%、31%和21%，视觉反馈结合心理练习后为47%、48%和47%，仅视觉反馈后为42%、48%和42%。当参与者进行视觉反馈结合心理练习时，他们将更大比例的体重放在患侧肢体上，且这种效果持续1小时。
这些发现表明，仅视觉反馈方法就能产生改善效果，但视觉反馈与心理练习相结合对改善和维持偏瘫性脑卒中患者的对称站立姿势会产生进一步的积极影响。
