Therapeutic exercise to improve motor function among children with Down Syndrome aged 0 to 3 years: a systematic literature review and meta‑analysis.

For infants and toddlers with Down Syndrome, therapists have long wondered whether therapeutic exercise programs help motor skills develop, and if so, which type and dose work best. This systematic review and meta-analysis pooled six randomized controlled trials with 151 participants aged 0 to 3 years, looking at outcomes like gait, balance, motor development, fine motor skills, and executive function. Two exercise types were identified across the trials, aerobic exercise (often treadmill-based) and neuromuscular exercise, and both were described as effective in improving these outcomes, with no clear differences between how they were applied. However, when specific comparisons were pooled, no statistically significant difference emerged between treadmill training and standard physiotherapy for time to independent walking or walking speed, with wide confidence intervals crossing zero.

The authors note substantial heterogeneity across studies and call for larger trials with more consistent methods before firmer conclusions can be drawn.

If you're a parent wondering whether structured exercise programs might help a young child with Down Syndrome move, walk, or develop motor skills, this review looked at exactly that. Researchers combined results from six randomized controlled trials involving 151 children aged 0 to 3, examining things like walking ability, balance, and fine motor skills.

They found two main types of exercise used in these studies, aerobic exercise (such as treadmill walking) and neuromuscular exercise, and both were linked to improvements in motor outcomes. That said, when researchers specifically compared treadmill training against standard physiotherapy for reaching independent walking or improving walking speed, the difference between the two wasn't statistically meaningful, meaning the studies couldn't confidently say one approach worked better than the other. The number of included studies was small and results varied quite a bit between them, so the overall evidence is still described as needing confirmation from bigger, more consistent studies.

This doesn't mean exercise programs don't help, only that the current evidence base isn't strong enough yet to draw firm conclusions about which specific approach is best.

This systematic review and meta-analysis synthesized six RCTs (n=151) examining therapeutic exercise for motor outcomes, including gait, balance, motor development, fine motor skills, and executive function, in children with Down Syndrome aged 0 to 3 years. Two exercise categories were identified, aerobic (predominantly treadmill-based) and neuromuscular, both reported as effective, with no differences detected between modes of application. Direct pooled comparisons, however, showed no statistically significant advantage of treadmill training over standard physiotherapy for time to independent ambulation (MD 46.79, 95% CI -32.60 to 126.19) or walking speed (MD 0.10 m/s, 95% CI -0.02 to 0.21), with confidence intervals crossing the null in both cases.

The authors proposed potential treadmill parameters (5 days/week, 6-8 minutes, 0.2-0.5 m/s) as a possible protocol, but this stems from a small, heterogeneous evidence base of only six trials. Clinicians should weigh these findings cautiously given the limited sample size, reported heterogeneity across studies, and the null result for the head-to-head treadmill comparison. The review does not establish superiority of one exercise modality over another, and larger, more methodologically consistent trials are needed to clarify effect sizes and optimal dosing parameters.
