The purpose of this study was to describe and compare the gait of 20 patients with hemiplegia secondary to cerebrovascular accident (CVA) before and after a treatment regimen of resisted pelvic motions. Ten women and 10 men were studied, with a mean age of 48 years and a mean duration post-CVA of two months. Nine subjects (45%) were right hemiplegic, and 11 subjects (55%) were left hemiplegic. Treatment consisted of four sets of five repetitions each of manually resisted pelvic anterior-elevation and posterior-depression movements on the involved side. An insole footswitch system, knee electrogoniometer, and force walking aid were used in gait analysis performed before treatment, immediately after treatment (posttest 1), and 30 minutes after treatment (posttest 2). Results showed significant overall improvement in gait in posttest 1 (p less than .005) compared with the pretest. This improvement, however, was not maintained in posttest 2. Ten patients improved overall in posttest 1; only 4 patients also showed improvement in posttest 2. The major improvements seen immediately after treatment were observed in stance stability and limb advancement in the involved limb. More research is needed to identify an optimum treatment with carry-over using this technique.
本研究的目的是描述和比较20例脑血管意外（CVA）继发偏瘫患者在进行抗阻骨盆运动治疗方案前后的步态。研究对象包括10名女性和10名男性，平均年龄48岁，CVA后平均病程两个月。9名受试者（45%）为右侧偏瘫，11名受试者（55%）为左侧偏瘫。治疗包括对患侧进行四组每组五次的手动抗阻骨盆前抬和后压运动。在治疗前、治疗后即刻（后测1）和治疗后30分钟（后测2）进行步态分析时，使用了鞋垫式脚踏开关系统、膝关节电子角度计和助力步行辅助器。结果显示，与治疗前相比，后测1的步态有显著的总体改善（p<0.005）。然而，这种改善在测试2中并未持续。10名患者在测试1中总体有所改善；只有4名患者在测试2中也显示出改善。治疗后即刻观察到的主要改善在于患侧的站立稳定性和肢体推进。需要更多的研究来确定使用该技术的最佳具有持续性效果的治疗方法。
