Physical Therapy for Sport-Related Concussion: A Network Meta-analysis and Systematic Review.

When athletes suffer a sport-related concussion, physical therapists have several possible exercise-based approaches to offer, from strict rest to structured aerobic protocols to vestibular rehabilitation, but which one actually helps recovery has been unclear. This review pooled data from 20 randomized trials to compare these approaches head to head using a statistical method that allows indirect comparisons across studies that did not test every option against every other. Across the pooled evidence, multidisciplinary interventions, meaning combined approaches rather than a single technique, showed the largest improvements in symptoms or recovery measures, with combined vestibular rehabilitation plus subthreshold aerobic exercise and vestibular rehabilitation alone following behind. This pattern held for younger participants and for those with persistent symptoms rather than acute concussion.

The finding is worth attention because it challenges older advice favoring rest, but the underlying trials varied in quality, with some carrying moderate or high risk of bias, so the strength of these conclusions is not uniform.

If you or someone you know has had a sports-related concussion, you may wonder what kind of rehabilitation actually helps recovery. Researchers combined the results of 20 clinical trials, involving over 1,300 people aged 12 to 60, to compare different recovery approaches including strict rest, stretching, aerobic exercise programs, vestibular (balance and eye movement) therapy, and combinations of these delivered by multiple types of specialists together. The pooled evidence suggested that combined, multidisciplinary treatment approaches were linked to the greatest improvement in symptoms, followed by combining vestibular therapy with a gradual aerobic exercise program, and then vestibular therapy alone.

This pattern appeared most clearly in people under 30 and in those still dealing with symptoms weeks after the initial injury, rather than in the earliest days after concussion. It's encouraging to see exercise-based approaches outperforming rest in this analysis, but the trials feeding into it varied in reliability, several carried a meaningful risk of bias, and the review does not tell you what any one individual should do. This is a summary of research patterns, not personalized medical guidance.

This network meta-analysis pooled 20 randomized controlled trials (n=1320, ages 12-60, 57% female) comparing exercise-based interventions for sport-related concussion, including subthreshold aerobic exercise protocols, usual care exercise protocols, multidisciplinary interventions, stretching, strict rest, vestibular rehabilitation therapy, and combined vestibular rehabilitation plus subthreshold aerobic exercise. Multidisciplinary interventions produced the largest standardized mean difference (SMD -2.06, P=0.002), with combined vestibular rehabilitation plus subthreshold aerobic exercise and vestibular rehabilitation alone showing the next largest effects, though exact figures for those comparisons were not detailed in the abstract. Subgroup analyses reinforced the primary finding, with multidisciplinary interventions showing the greatest benefit in participants under 30 (SMD -2.42) and in those with persistent rather than acute symptoms (SMD -2.999).

Risk of bias assessment via the Cochrane tool found low risk in 13 studies, moderate in 3, and high in 4, meaning roughly a third of the evidence base carries some methodological concern. As a network meta-analysis, these rankings rely on indirect comparisons across a heterogeneous set of trials, and sport type and competition level were poorly reported, limiting generalizability. The findings support exercise-based rehabilitation over strict rest but should be interpreted with attention to the mixed risk-of-bias profile across included studies.
