PMID 39127667WHAT IT FOUND
Chronic stroke patients using an MR board for four weeks improved hand function, finger movement, and perceived recovery.
No control group means we cannot know if this training caused the changes.
Key findings
01Hand function measures improved after training, but proximal arm scores did not.
02Finger range of motion increased significantly across all joints during the intervention.
03Participants reported better stroke recovery on the self-reported scale.

What it does not show
There was no control group, so improvement cannot be attributed to the MR board rather than natural recovery or the passage of time. The sample size was small, with only 21 participants initially. Nine of the twenty remaining participants missed the follow-up assessment, and missing data were estimated rather than measured. The training content varied between participants, making it unclear which specific exercises drove the results. The test used for finger individuation was not standardized.
The easy way to misread this
Do not assume this device causes the observed improvements. Without a control group, the gains could reflect natural recovery or placebo effects. Also, do not expect it to improve shoulder or elbow function, as proximal scores did not change.
