Remote back-pain rehab matched the clinic on pain

Chronic low back pain is one of the leading causes of disability worldwide and generates enormous demand for rehabilitation appointments that health systems struggle to supply. Remote delivery is the obvious pressure valve, and it exploded during the pandemic, but the question of whether the delivery mode itself changes outcomes was never cleanly answered. Earlier reviews muddled things by lumping in paper handouts and hybrid programmes, which makes it impossible to tell whether any difference comes from the content or from the screen. This review tried to isolate the delivery pathway itself.

The authors searched four major databases for randomised controlled trials comparing telerehabilitation with face-to-face rehabilitation in adults with chronic low back pain. They applied strict eligibility rules designed to separate the two delivery routes, excluding paper-based home exercise programmes, continuous hybrid delivery and designs where only the assessment was remote. Results were pooled using random-effects models with standardised mean differences. Risk of bias and certainty of evidence were assessed with the standard Cochrane and GRADE tools, alongside sensitivity and subgroup analyses. Ten trials with 562 participants were included.

In the content-matched primary analyses, there was no significant difference between the two modes for pain intensity across 7 trials or for functional disability across 8 trials. When two further trials were added in which only the face-to-face group also received manual therapy, pain still did not differ across 9 trials, but functional disability now favoured in-person care across 10 trials. Subgroup tests for intervention duration, weekly frequency and whether sessions were supervised were all non-significant. The authors emphasise that certainty was low for disability and very low for pain, and that the disability estimate was sensitive to dropping a single study.

This refines a question that previous work left blurred, by deliberately stripping out hybrid and paper-based designs to look at delivery mode alone. The result is consistent with the idea that the exercise content, not the channel it arrives through, does most of the work. The hands-on manual therapy comparison is the interesting complication: when in-person groups got something extra, disability outcomes tilted their way. Open questions the authors name include longer follow-up, better matched interventions, and direct comparisons of supervised versus unsupervised remote delivery, which this evidence could not separate.

If distance, cost or scheduling is what keeps you from doing supervised rehab for persistent back pain, this suggests a remote programme delivering the same exercises is a reasonable option rather than a clearly inferior one. The honest caveat is that the authors explicitly refuse to call the two equivalent, because the underlying trials were few, small and of uneven quality. Note too that the in-person advantage appeared only where clinics added hands-on treatment, which remote care cannot replicate. Nothing here tells you which exercises to do, only that the channel may matter less than people assume.
