Use of the Leap Motion Controller® System in the Rehabilitation of the Upper Limb in Stroke. A Systematic Review

Abstract

Objectives Upper limb impairment is the most common motor impairment in stroke survivors. The use of new technologies in the field of rehabilitation aims to reduce the impact of functional problems. Our objective is to evaluate the effectiveness of using the Leap Motion Controller® virtual reality system in the treatment of upper limb functionality in people with stroke.

Materials and Methods PRISMA guidelines were used to carry out the systematic review. The literature search was restricted to articles written in English or Spanish published from 2012 to December 2020 in Pubmed, Web of Science, Scopus, PEDro and Science Direct. Of the 309 search results, 230 unique references were reviewed after duplicates were removed. The Downs and Black and CONSORT scales were applied to evaluate the methodological quality of the included papers and the degree of evidence and level of recommendation were determined through the Oxford Centre for Evidence-Based Medicine.

Results Six papers with a total of 144 participants were included in this review, with heterogeneity of the sample, assessment measures, protocols, number of sessions and diversity of games applied. The main results of the studies show favourable data after using the Leap Motion Controller® system in the improvement of upper limb functionality in people with stroke.

Conclusions There is a growing trend in the use of the Leap Motion Controller® device as a tool in the treatment of the upper limb in people with stroke. Nevertheless, the limitations encountered suggest the need for future research protocols with greater scientific rigor.
