Effects of Technology-Assisted Rehabilitation After Spinal Cord Injury: Pilot Randomized Controlled Crossover Trial.
Mia Maria Kilkki, Joonas Poutanen, Kari Kauranen and 2 others
PMID 41037657WHAT IT FOUND
Technology-assisted hand rehabilitation did not improve overall arm function compared to no treatment, but most participants achieved their personal goals.
It was safe and well-tolerated, though the small study size means it cannot prove the devices work better than standard care.
Key findings
01There was no statistically significant difference between the rehabilitation intervention and no intervention for most outcomes, except for a small improvement in muscle strength in one group.
02Fourteen out of sixteen participants achieved their personally set rehabilitation goals, with a median Goal Attainment Scale T score of 50.
03The intervention was feasible and safe, with 89% of enrolled participants completing at least 80% of sessions and only one report of pain.

What it does not show
The study was underpowered due to recruitment challenges, with only 16 participants analyzed against a target of 60, increasing the risk of missing true effects. Participants and therapists were not blinded, which may have biased self-reported outcomes and goal attainment. Ceiling effects were observed in key outcome measures (ARAT and SCIM-SR) because many participants already had mild disability and high baseline function. The crossover design carried a risk of carryover effects, where benefits from the first period may have persisted into the second, potentially masking differences.
Declared interests
None declared.
The easy way to misread this
Do not interpret the high rate of personal goal attainment as evidence that the technology itself caused the improvement. Since participants were not blinded and the control period was 'no intervention' rather than 'sham' or 'standard care' alone, the success may reflect the intensive therapist contact, personalized goal setting, or natural variation rather than the specific devices.
