Background:

Stroke often results in chronic motor deficits.
Wearable exoskeletons offer potential for home-based rehabilitation.
Brain plasticity is key to motor recovery after stroke.

Purpose of the Study:

To evaluate the efficacy of the HandSOME II wearable hand exoskeleton for home-based rehabilitation in chronic stroke survivors.
To assess improvements in motor function, tone, and real-world limb use.
To investigate the relationship between brain reorganization (EEG) and motor recovery.

Main Methods:

A longitudinal study involving 15 individuals with chronic stroke using HandSOME II at home for 8 weeks.
Weekly clinic visits for monitoring and troubleshooting.
Clinical evaluations (Action Research Arm Test, Modified Ashworth Test, Motor Activity Log) and biomechanical testing pre- and post-intervention, and at 3-month follow-up.
Electroencephalography (EEG) to assess brain reorganization.

Main Results:

Significant improvements (p < 0.05) in functional ability, flexor tone, and real-world limb use after 8 weeks.
Gains in real-world use were retained at 3-month follow-up (p = 0.005).
Significant gains in finger range of motion and hand displacement during reaching tasks.
Baseline and changes in EEG functional connectivity correlated with motor function gains and recovery.

Conclusions:

The HandSOME II is a low-cost, home-based intervention for chronic stroke.
The exoskeleton elicits brain plasticity, leading to improved functional motor outcomes.
Home-based use of wearable exoskeletons can be effective for stroke rehabilitation.
