Effects of virtual reality training in the upper limb motor coordination of individuals post- stroke: a systematic review with meta-analysis

Abstract

After a stroke, 75% of people are affected in their upper limbs, remaining with sequelae at these limbs. Results from recent clinical trials have been contradictory regarding the effectiveness of Virtual Reality (VR) therapy in rehabilitating upper limb motor coordination in this population. This study aimed to perform a systematic literature review with meta-analysis to investigate the effects of VR training on upper limb motor coordination in patients post-stroke. Searches were performed in the electronic databases PubMed, LILACS, SciELO, PEDro, in addition to manual searches. The whole process was performed by two independent raters. The methodological quality of the studies was assessed by the PEDro scale. In total, we selected 18 studies, out of which only 13 were included in the meta-analysis. In general, VR training was effective in improving upper limb motor coordination (SMD 0.32; 95% CI 0.08-0.56; I2=42%; p<0.01). When subgroup analysis assessed control group type, VR training was superior than no intervention (SMD 0.36; 95% CI: 0.06-0.66; p<0.05). However, when compared to other interventions, we found no significant difference (SMD 0.26; 95% CI: −0.12-0.64; p=0.18). Overall, VR training is effective in improving upper limb motor coordination in post-stroke individuals compared to no intervention. However, it shows no superiority when compared to other types of intervention used in the rehabilitation of upper limb motor coordination in these patients.

Telehealth-Guided Virtual Reality for Recovery of Upper Extremity Function Following Stroke

“…Similarly, guidelines from the American Heart Association/ American Stroke Association include recognition that virtual reality is a viable option for clients to engage in rehabilitation and maximize the amount of movement and practice to promote recovery (Winstein et al, 2016). Multiple reviews have found that virtual reality interventions are equally effective to traditional therapy for improving UE function post-stroke (Meireles et al, 2022; Yates et al, 2016). Recently developed virtual world-based games allow clients to practice realistic occupations while also completing the recommended repetitions of UE movements.…”
