Is remote rehabilitation as effective as in-person care?

Twenty-two trials, no difference found

Laver and colleagues gathered 22 trials and 1,937 participants to examine rehabilitation delivered remotely after a stroke. The comparisons bear on functional outcomes and on independence in activities of daily living.

The conclusion is an absence of difference: the authors find no superiority of in-person care on the outcomes studied. An absence of difference is not proof of equivalence, and the review says so. The included trials are of modest size, their protocols differ widely, and the level of confidence attached to the results remains low to moderate depending on the outcomes considered.

Distance is not the interesting variable

Set alongside the work on intensity, this conclusion changes meaning. If the delivery channel does not explain the difference in results, then the factor that does explain it lies elsewhere: in the amount of work actually carried out. The useful question is therefore not whether the screen is worth the consulting room, but what the screen makes possible that the consulting room alone does not.

And what distance makes possible is frequency. A weekly session remains a weekly session; between two appointments stretch six days during which nothing is worked on, unless something has been planned for it. It is this continuity, not the saved journey, that meets the volumes of hours associated with the best progress in the aphasia literature.

See on this point intensity in aphasia rehabilitation, and in particular the gap between the recommended dose and the actual dose.

One word for very different arrangements

In these trials, telerehabilitation covers arrangements that differ considerably from one another. Some rest on a videoconference session, in which the clinician conducts the work live through a screen. Others rest on a programme of activities the person carries out alone, with asynchronous follow-up and regular check-ins. Others still combine the two, or alternate with in-person appointments.

This heterogeneity accounts for part of the authors’ caution. It also indicates that the question “is distance worth presence” is badly framed: the protocols tested do not replace the clinician, they shift the moment at which the clinician intervenes. In almost every case, someone prepares, adjusts and reviews what has been done.

Nothing in these trials supports the idea of rehabilitation without a clinician. It is a reading one sometimes encounters; it has no support in these data.

The blind spots of this literature

A review of this nature says nothing about access. It compares patients who were able to enter a trial, and who therefore had equipment, a connection and, most often, people around them able to help at the start. The people whom distance excludes do not appear in the numbers, by construction. For a service, the practical question is therefore not only the effectiveness of the arrangement, but the identification of the patients for whom it is not workable.

Nor does it say anything about the therapeutic alliance, which is not an outcome measure in these trials even though it occupies a central place in real work. We have no grounds to assert that it carries over intact at a distance, nor the contrary. This is an area where the clinician’s judgement remains the only resource available.

It says nothing, finally, about language disorders in particular. The trials gathered concern rehabilitation after stroke in the broad sense, motor rehabilitation included. Transposing their conclusions to speech and language work calls for a caution that the review itself does not explicitly authorise.

From the person’s side

Seen from the person’s side, the value of the arrangement does not turn on the journey avoided. It turns on what happens on Tuesday, Thursday and Saturday, when the session is far away. An exercise available on those days turns a course of care into a daily activity, which is a change of kind more than of degree.

Two side effects deserve mention, one favourable, the other not. The first is that the patient regains a share of initiative: they choose their moment, their pace, and they see their results. This recovered autonomy is regularly cited by the people concerned as a benefit in itself.

The second is the opposite risk. Poorly calibrated work at home puts the person in a situation of repeated failure, with no one there to defuse it. Difficulty must therefore be set a notch below what is practised in the session, where the clinician can prompt again. This adjustment is not documented by the trials; it belongs to clinical experience.

What this implies day to day

The most solid reading of this literature is a modest one: distance is not a demonstrated obstacle, and it lifts a scheduling constraint. It replaces neither the assessment, nor the moments when presence does the work.

In practice, the division that emerges from these data places in the session what requires the clinician’s eye, fine adjustment and prompting, and outside the session what belongs to repetition and volume. Telerehabilitation then becomes a means of reaching a dose, rather than a competing mode of practice.

Three conditions recur in the protocols that work. The material must be usable without technical assistance, which rules out most arrangements requiring an installation. The patient must know what to do without having to ask again, and therefore have brief instructions and a series already assembled. And the clinician must get something usable back, otherwise the work done remains invisible and does not inform the next session.

The point of vigilance concerns the third. An arrangement that produces a lot of data without making it readable adds work instead of removing it. This is not an objection to telerehabilitation; it is a selection criterion.

How doMind puts this into practice

doMind was built for this division. The clinician prepares, from their own workstation, a series of activities adjusted to the patient; the patient works at home, on a tablet or a computer, and the results come back to the clinician before the next session. The platform does not conduct the rehabilitation: it carries what happens between sessions, which is precisely the point the literature designates. Discover the tool.
