How strong is the evidence for Mobility?

Evidence on mobility and flexibility training is supported by a Cochrane systematic review showing mobility training improves function in frail older adults, alongside randomized trials in specific clinical populations such as stroke and Parkinson's disease showing gains in walking and motor function. That evidence is currently rated moderate (68/100), built on 4 published studies, including 2 meta-analyses -- a reasonable base, but not yet enough for full certainty.
