Physical rehabilitation interventions in children with acquired brain injury: a scoping review.

PMID 34309829WHAT IT FOUND
Nine studies mapped physical rehab for children with acquired brain injury, but none reported intervention intensity.
While all showed positive body-function gains, the evidence is too heterogeneous to prove which treatments work best or how much practice is needed.
Key findings
01None of the included studies reported details on the intensity of the intervention, making it impossible to determine the optimal dose.
02All included studies reported positive effects on physical outcomes at the body function and activity levels, but no studies measured participation.
03The evidence base is limited by small sample sizes and high heterogeneity in injury types and ages, preventing firm conclusions about treatment benefits.

What it does not show
No formal quality assessment of included studies was performed. The review is a scoping review, not a meta-analysis, so it maps evidence rather than quantifying effect sizes. Included studies were highly heterogeneous in injury type, age, and intervention details. Sample sizes were very small for most studies (n ≤ 12), limiting generalizability. Intensity of intervention was not reported in any study, creating a major gap in understanding dose-response relationships. No studies reported adverse events or negative results.
Declared interests
The authors declared no conflicts of interest. The review was supported by non-US government funding sources, though specific funder influence on design or reporting was not detailed in the provided text.
The easy way to misread this
Do not interpret the positive physical outcomes reported in all nine studies as proof that these specific interventions caused the recovery. The studies lacked control groups or comparison to usual care, and spontaneous recovery is common in the subacute phase of acquired brain injury.
