Unsupervised robot-assisted rehabilitation after stroke: feasibility, effect on therapy dose, and user experience.
Giada Devittori, Daria Dinacci, Davide Romiti and 6 others
PMID 38594727WHAT IT FOUND
Twelve of thirteen subacute stroke inpatients used a hand robot unsupervised without safety issues.
They averaged 77% attendance and added about 6 hours of therapy over two weeks. Usability scores did not drop when the therapist left the room.
Key findings
01Twelve of thirteen participants progressed to unsupervised training with no adverse events or device deficiencies.
02Mean attendance during the unsupervised phase was 77.0%, and participants averaged 360.0 minutes of robotic therapy over two complete weeks.
03Usability and user experience scores showed no significant difference between the minimally supervised and unsupervised phases.

What it does not show
Very small sample (13 participants) with no control group, so functional improvements cannot be attributed to the robot rather than usual care or natural recovery. Excluded patients with moderate-to-severe aphasia or cognitive deficits, so feasibility is unknown for those groups. Conducted in a structured inpatient environment with routine and scheduled timeslots, which may not translate to home settings. One participant did not progress to unsupervised use due to safety concerns (excessive force), and another needed extra familiarisation due to motor impairments in the non-trained arm. Attendance dropped on weekends, possibly due to lack of scheduled timeslots or patient routines. Therapy sessions were voluntary with no dose targets, so actual engagement varied widely.

The easy way to misread this
Do not interpret the functional improvements (e.g., FMA-UE increase of 9.7 points) as evidence that unsupervised robot therapy causes recovery. This was a single-group pilot with no control, so all participants also received usual care, and improvement may reflect natural recovery or conventional therapy.
