Analysing the PubMed database searching for "rehabilitation", "games" and "trial" one finds 826 articles produced in the last 10 years. Adding "clinical trial" available papers are reduced to 498 and adding "neurology" we get to 29 papers which can be found here https://pubmed.ncbi.nlm.nih.gov/?term=rehabilitation+games+trial+neurology&filter=pubt.clinicaltrial&filter=datesearch.y_10 [November 2020]
