The hypotheses have been tested that 1) symmetry of weightbearing in persons who have sustained a stroke could be improved by the addition of a lift to the shoe on the non-paretic lower limb and 2) compelled weightbearing resulting from the addition of a lift in conjunction with targeted exercise helps to overcome the learned disuse of the paretic limb. Weightbearing on the paretic side was measured in eight persons with hemiparesis during quiet standing and in conditions of compelled weight shift. Compelled weight shifts were applied with special lifts to the shoe on the non-paretic limb of the subjects. An increase in symmetrical weightbearing was recorded in conditions of compelled weight shifts: 10-mm lift provided the best symmetry of bipedal standing. We suggest that improved symmetry of bipedal standing obtained with the lift of the non-paretic limb would help in overcoming the learned disuse of the affected limb. Pre- and post-test results of a person with hemiparesis who was wearing a shoe lift on the non-paretic limb during a 6-week physical therapy program showed statistically significant improvement of walking speed, stride length, and weightbearing. Such findings support the idea of using compelled weightbearing via lifting and targeted exercise during treatment.
1）对于中风患者，在非患侧下肢的鞋子上增加一个鞋垫可以改善其负重对称性；2）增加鞋垫并结合有针对性的锻炼所产生的强制性负重有助于克服患侧肢体习得性废用。在安静站立和强制性体重转移的情况下，对8名偏瘫患者的患侧负重情况进行了测量。通过在受试者非患侧肢体的鞋子上使用特殊鞋垫来施加强制性体重转移。在强制性体重转移的情况下，记录到对称负重有所增加：10毫米的鞋垫提供了最佳的双足站立对称性。我们认为，通过抬高非患侧肢体获得的双足站立对称性改善将有助于克服患侧肢体的习得性废用。一名偏瘫患者在为期6周的物理治疗计划中，在非患侧肢体上穿着鞋垫，其测试前后的结果显示，步行速度、步幅和负重都有统计学上的显著改善。这些发现支持了在治疗过程中通过抬高和有针对性的锻炼来使用强制性负重的观点。
