To investigate the effect of antigravity treadmill gait training (AGT) on gait function, balance, and fall risk in stroke patients.
This study included 30 patients with stroke (mean age, 73 years). All subjects were randomly divided into two groups. The intervention group (n=15) performed AGT for 20 minutes, five times per week for 4 weeks. The control group (n=15) received conventional gait training for the same duration. To assess fall risk, the Tinetti Performance-Oriented Mobility Assessment (POMA) was measured. The Berg Balance Scale (BBS), Timed Up and Go test (TUG), and 10-m walk test (10mWT) were measured to assess dynamic balance. All scales were measured before intervention (T0) and at 4 weeks (T1) and 12 weeks (T2) after intervention.
Results showed that the total POMA score, BBS, and 10mWT scores improved significantly (p<0.05) at T1 and T2 in both groups. The POMA gait score (4.20±1.37 at T1, 4.87±1.36 at T2) and TUG (4.52±4.30 at T1, 5.73±4.97 at T2) significantly improved (p<0.05) only in the intervention group. The changes in total POMA score and BBS of the intervention group (7.20±2.37, 7.47±3.07) improved more significantly (p<0.05) between T0 and T2 than the control group (2.53±2.10, 2.87±2.53).
Our study showed that AGT enhances dynamic balance and gait speed and effectively lowers fall risk in stroke patients. Compared to conventional gait therapy, AGT would improve gait function and balance in stroke patients more effectively.
探讨抗重力跑步机步态训练（AGT）对脑卒中患者步态功能、平衡能力及跌倒风险的影响。
本研究纳入30例脑卒中患者（平均年龄73岁）。所有受试者随机分为两组。干预组（n = 15）进行20分钟的AGT训练，每周5次，共4周。对照组（n = 15）接受相同时长的传统步态训练。为评估跌倒风险，采用Tinetti以功能为导向的移动性评估（POMA）。采用Berg平衡量表（BBS）、计时起立行走测试（TUG）和10米步行测试（10mWT）评估动态平衡。所有量表在干预前（T0）、干预后4周（T1）和12周（T2）进行测量。
结果显示，两组在T1和T2时POMA总分、BBS和10mWT评分均显著改善（p < 0.05）。仅干预组的POMA步态评分（T1时为4.20±1.37，T2时为4.87±1.36）和TUG（T1时为4.52±4.30，T2时为5.73±4.97）显著改善（p < 0.05）。干预组T0至T2期间POMA总分和BBS的变化（7.20±2.37，7.47±3.07）比对照组（2.53±2.10，2.87±2.53）改善更显著（p < 0.05）。
我们的研究表明，AGT可增强脑卒中患者的动态平衡和步态速度，并有效降低跌倒风险。与传统步态治疗相比，AGT能更有效地改善脑卒中患者的步态功能和平衡能力。
