Brain-machine interface training was developed for upper-extremity
rehabilitation for patients with severe hemiparesis. Its clinical application,
however, has been limited because of its lack of feasibility in real-world
rehabilitation settings. We developed a new compact task-specific brain-machine
interface system that enables task-specific training, including reach-and-grasp
tasks, and studied its clinical feasibility and effectiveness for upper-extremity
motor paralysis in patients with stroke. DESIGN: Prospective beforeaeuro"after
study. SUBJECTS: Twenty-six patients with severe chronic hemiparetic stroke.
METHODS: Participants were trained with the brain-machine interface system to
pick up and release pegs during 40-min sessions and 40 min of standard
occupational therapy per day for 10 days. Fugl-Meyer upper-extremity motor (FMA)
and Motor Activity Log-14 amount of use (MAL-AOU) scores were assessed before and
after the intervention. To test its feasibility, 4 occupational therapists who
operated the system for the first time assessed it with the Quebec User
Evaluation of Satisfaction with assistive Technology (QUEST) 2.0. RESULTS: FMA
and MAL-AOU scores improved significantly after brain-machine interface training,
with the effect sizes being medium and large, respectively (p<0.01, d=0.55;
p<0.01, d=0.88). QUEST effectiveness and safety scores showed feasibility and
satisfaction in the clinical setting. CONCLUSION: Our newly developed compact
brain-machine interface system is feasible for use in real-world clinical
settings.
