Home telerehabilitation after stroke is being tested as a way to deliver structured practice with therapist support. Evidence for a supervised programme should not be read as proof that any rehabilitation game or app provides the same benefit. The most useful distinction is what the programme is being compared with.
UCLA’s October account describes a home system using games to support arm and hand practice, with therapists monitoring progress and adjusting the work. The ongoing TR-2 study asks whether adding that programme to usual care improves recovery. It is a different question from an earlier trial comparing home and clinic delivery of matched therapy. UCLA account, TR-2 record
The game is part of a therapy programme
A game can organise repeated movement, feedback and changing difficulty. In the programme described by UCLA, it sits within a structured intervention rather than functioning as a standalone consumer game. Therapist involvement and the amount of practice are part of what is being tested.
That makes the software one component of the intervention. A result cannot automatically be transferred to a different app, a different exercise dose or a programme with no professional support. System and therapist role
What the earlier trial established
The 2019 JAMA Neurology trial randomised 124 participants across 11 US sites to home telerehabilitation or in-clinic therapy. Both groups received 36 sessions of arm training and stroke education, with session duration, frequency and intensity matched.
It was a noninferiority trial: the analysis tested whether home delivery was not unacceptably worse than clinic delivery within a prespecified margin. The researchers reported that the home programme met that criterion for improvement in arm motor function, measured using the Fugl-Meyer assessment. Methods and primary analysis
That supports a bounded comparison between two structured programmes. It does not establish superiority of home therapy, equivalence for every outcome or the effectiveness of an arbitrary unsupervised game. Participants also had defined arm impairment and were enrolled within the study’s specified post-stroke period; they were not a sample of every person recovering from stroke.
TR-2 changes the comparator
The current TR-2 registry describes random assignment to telerehabilitation plus usual care or usual care alone. Its primary outcome concerns change in the Action Research Arm Test at two months. This assesses arm and hand activity; it is not the same primary measure as the earlier study’s Fugl-Meyer motor assessment.
The registry update posted on 9 October lists the study as recruiting, with an estimated primary-completion date in 2029. Those are study-status details, not evidence that the added programme has already improved recovery. Design, outcomes and status
| Study question | Comparator | What it can address |
|---|---|---|
| Earlier 2019 trial | Home programme versus dose-matched clinic therapy | Whether the tested home delivery meets the prespecified noninferiority criterion for arm motor improvement |
| Ongoing TR-2 | Added home programme plus usual care versus usual care alone | Whether adding the tested programme improves the specified recovery outcomes |
These questions cannot be combined into a universal claim that home rehabilitation is better than clinic care. Earlier trial, Current trial
The wider evidence covers different interventions
A 2026 systematic review of exercise-based telerehabilitation searched studies published through December 2025. It brought together supervised, caregiver-mediated, autonomous and hybrid approaches. Differences in programmes, comparisons and outcome measures led the authors to a narrative synthesis rather than one pooled effect estimate.
The review describes potential and some broadly comparable outcomes, with important uncertainty about which components work for whom. It also cautions that safety was not a predefined review outcome. An absence of reported serious events in the included accounts cannot certify the safety of every home programme. Methods, discussion and limitations
Read the programme and the outcome together
For a rehabilitation service assessing this approach, the relevant questions include the supported population, therapist contact, planned practice, equipment, comparator and outcome. A gain on an arm-function scale and greater independence in daily life are related aims, but they are not interchangeable findings.
The research makes a practical delivery question testable: can supported practice reach people at home, and what does that add to their existing care? The answer will depend on the complete programme and the results of the relevant comparison, rather than the presence of a game on a screen.
