In a nutshell
The aim of this study was to investigate how effective electromechanical (EM) and robot-assisted (RA) arm training is for improving arm strength and function after a stroke. The main finding of the study was that patients who used electromechanical and robot-assisted arm training might improve their arm function and strength.
Some background
More than two-thirds of patients have problems with arm function after having a stroke. This can make it difficult to do everyday tasks such as dressing, washing, and cooking (activities of daily living). It can also make it difficult to work and socialize. Therefore, improving hand and arm function is a priority in stroke recovery.
EM and RA arm training uses specialized machines to assist rehabilitation by supporting the shoulder, elbow and hand movements. It is still unclear if EM and RA arm training is effective for improving arm and hand function after a stroke.
Methods & findings
This study included data from 34 trials, including 1160 patients in total. 19 different EM devices were used in different trials. The trials compared EM and RA arm training with different other rehabilitation strategies.
Patients treated with EM and RA arm training had moderately improved activities of daily living compared to those who were treated with other rehabilitation strategies. There was only a small improvement in arm function and strength in those treated with EM and RA arm training compared to those who had other rehabilitation interventions.
The bottom line
The authors concluded that EM and RA arm training might improve activities of daily living and arm strength and function.
The fine print
The quality of the studies analyzed was very low as there was a lot of variation between trials durations, type of treatment, amount of training etc.
