Medical devices for self-help management: the case of stroke rehabilitation

Introduction: Self-help devices (SHD) have been used as an alternative to conventional treatment for post stroke rehabilitation. This review aims to look for evidence that a stroke survivor may have increased muscle strength with the use of SHD. Methods: This article was conducted according to PRISMA, a statistical tool (state of the art by systematic review) and previously registered in PROSPERO (international prospective registry of systematic reviews) under number CRD42018091424. Studies addressing the use of SHD and its effect on muscle strength in stroke patients were included. The studies were read, selected and their metadata extracted. A Downs & Black scale was used to assess methodological quality. Results: 41 publications were analyzed, of which only three met the proposed inclusion criteria. Two articles showed positive results in strength gain using SHD. One study presented a decrease in the mean reaching forces when compared to the intervention groups (subacute and chronic with assistance to grip) and controls but SHD assisted in performing the activity. Conclusion: Studies using SHD suggest muscle strength improvement in stroke patients.
