Abstract

Abstract:

Objective To investigate the effect of virtual reality treadmill training on limb motor function in patients with ischemic stroke.

Methods This study prospectively enrolled consecutive patients with ischemic stroke who met the entry criteria from January to June 2021. All the included patients were randomly divided into the observation group and control group using the random number table method. The conventional rehabilitation training was used in control group, and the conventional rehabilitation plus virtual reality treadmill training were used in observation group. The NIHSS, Fugl-Meyer motor assessment (FMA), Berg balance scale (BBS), 6-minute walking test (6MWT), functional gait assessment (FGA), and modified Barthel index (MBI) were used to assess the limb motor function, balance, walking ability, and activities of daily living by the same assessor before and 4 weeks afterthe rehabilitation treatment.

Results A total of 53 patients were included in the final analysis, including 27 cases in observation group and 26 cases in control group. Before treatment, the NIHSS, FMA, BBS, 6MWT, FGA and MBI scores between the two groups all had no statistical differences (P >0.05). After 4 weeks of treatment, the NIHSS scores in the two groups were lower than before treatment, and the FMA, BBS, 6MWT, FGA, and MBI scores were higher than before treatment, and the above differences were all statistically significant (P <0.05). After 4 weeks of intervention, the FMA score [93.0 (83.0- 100.0) points vs . 82.5 (68.0-94.0) points, P =0.020] and FGA score [19.0 (13.0-22.0) points vs . 14.0 (8.8-17.3) points, P =0.048] were higher in observation group than those in control group, while there were no statistical differences in the NIHSS, BBS, 6MWT, and MBI scores between the two groups (P >0.05).

Conclusions Virtual reality treadmill training can improve motor ability, balance, walking ability and activities of daily living in ischemic stroke patients. Compared with conventional rehabilitation training, virtual reality treadmill training is more effective in improving motor and walking ability in ischemic stroke patients.

摘要：

目的探讨虚拟现实跑台训练对缺血性卒中患者肢体运动功能的影响。

方法 2021年1-6月前瞻性连续选择符合入排标准的缺血性卒中患者，采用随机数字表法将患者随机分成试验组和对照组。对照组进行常规康复训练，试验组在常规康复训练基础上联合虚拟现实跑台训练。康复治疗前和治疗4周后由同一名评估者采用NIHSS、Fugl-Meyer运动功能评定量表（Fugl - Meyer motor assessment，FMA）、Berg平衡量表（Berg balance scale，BBS）、6 min步行试验（6-minute walking test，6MWT）、功能性步态评价（functional gait assessment，FGA）、改良巴氏指数（modified Barthel index，MBI）对患者进行肢体运动功能、平衡功能、步行能力及日常生活能力的评定。

结果共纳入53例患者，试验组27例，对照组26例。治疗前，两组患者NIHSS、FMA、BBS、6MWT、FGA、 MBI评分差异均无统计学意义。经过4周治疗，试验组、对照组患者NIHSS评分均较治疗前降低，FMA、 BBS、6MWT、FGA、MBI评分均较治疗前明显提高，差异均有统计学意义（P＜0.05）。干预4周后，试验组FMA评分[93.0（83.0～100.0）分 vs. 82.5（68.0～94.0）分，P =0.020]和FGA评分[19.0（13.0～22.0）分 vs. 14.0（8.8～17.3）分，P =0.048]均高于对照组，但NI HSS、BBS、6MWT、MBI 评分与对照组差异无统计学意义（P＞0.05）。

结论虚拟现实跑台训练可提高缺血性卒中患者运动能力、平衡功能、步行能力及日常生活活动能力。与常规康复训练相比，虚拟现实跑台在提高缺血性卒中患者运动能力和步行能力方面更有效。
