BACKGROUND: Patients with stroke have hypomobility in the facet joint of affected side. Lumbar joint mobilization could be used to maintain function and mobility of the joints. OBJECTIVE: This study aimed to investigate the effects of lumbar joint mobilization on trunk function, postural balance, and gait in patients with stroke. METHODS: Thirty patients with stroke were randomly assigned to two groups. Lumbar joint mobilization was provided for 15 min, 5 times a week for 6 weeks to patients who were allocated into the experimental group. Patients who were allocated into the control group received a sham intervention. Trunk function (trunk impairment scale), postural balance (weight distribution, Berg balance scale, and timed up and go test), and walking (10 m walk test, functional gait assessment, step length, and stride length) were evaluated before and after the experiment for all the patients. RESULTS: Lumbar joint mobilization significantly improved trunk function, postural balance, and gait compared with pre-test values in the experimental group (P< 0.05). Significant differences were seen in trunk function, postural balance, and walking between the two groups (P< 0.05). CONCLUSION: Lumbar joint mobilization might be an effective intervention for trunk function, postural balance, and walking in patients with stroke.

腰椎关节松动对慢性卒中患者躯干功能、姿势平衡和步态的影响：一项随机试验研究

背景：中风患者患侧小关节活动度低下。腰椎关节松动术可用于维持关节的功能和活动度。目的：本研究旨在探讨腰椎关节松动术对脑卒中患者躯干功能、姿势平衡和步态的影响。方法：30 名脑卒中患者被随机分配到两组。为分配到实验组的患者提供腰椎关节松动术，每次 15 分钟，每周 5 次，持续 6 周。被分配到对照组的患者接受了假干预。躯干功能（躯干损伤量表）、姿势平衡（体重分布、Berg 平衡量表和计时起步测试）和步行（10 米步行测试、功能性步态评估、步长、和步幅）在实验前后对所有患者进行了评估。结果：与实验前测试值相比，腰椎关节松动显着改善了躯干功能、姿势平衡和步态（P < 0.05）。两组躯干功能、姿势平衡、行走等方面差异有统计学意义（P<0.05）。结论：腰椎关节松动术可能是脑卒中患者躯干功能、姿势平衡和行走的有效干预措施。行走在两组之间（P<0.05）。结论：腰椎关节松动术可能是脑卒中患者躯干功能、姿势平衡和行走的有效干预措施。行走在两组之间（P<0.05）。结论：腰椎关节松动术可能是脑卒中患者躯干功能、姿势平衡和行走的有效干预措施。
