Abstract:

 Objective： To analyze the effects of virtual reality （VR） interactive balance training combined with intelligent motor feedback training on functional recovery， muscle strength and gait in patients with post-stroke lower-limb hemiplegia （PSLH）.Methods： 128 patients with PSLH admitted in our hospital were enrolled and randomly divided into the control group and the study group between February 2020 and February 2022， 64 cases in each group. The control group was given intelligent motor feedback training， while the study group was additionally given VR interactive balance training. All patients were treated for 2 months. The functional recovery ［Fugl-Meyer motor function assessment （FMA）， Berg balance scale （BBS）， functional ambulation category scale （FAC）］， muscle strength （grading of muscle strength）， gait （stride frequency， pace， step length）， quality of life （Barthel index） and adverse events in the two groups were compared.Results： After treatment， the FMA and BBS scores of the two groups of patients were increased （P<0.05）， and increase in FMA and BBS scores of the PSLH patients in the study group was better than that in the control group （P<0.05）.The FAC grade and muscle strength grade of the two groups of patients were improved， and the improvement of the FAC grade and muscle strength grade of the PSLH in the study group was better than that in the control group （P<0.05）.After treatment， the stride frequency， stride speed and stride length of the two groups of patients were increased （P<0.05）， and the increase in stride frequency， stride speed and stride length of the PSLH patients in the study group was better than that in the control group （P<0.05）.The Barthel score of the study group patients was higher than that of the control group （P<0.05）.No obvious adverse reactions occurred in the two groups of patients during the treatment period.Conclusion： VR interactive balance training combined with intelligent motor feedback training can effectively improve clinical curative effect， promote functional recovery， improve muscle strength， gait and quality of life in PSLH patients， with good safety.
