Effects of Mirror Therapy on Hand Function in Children with Spastic Cerebral Palsy: A Systematic Review and Meta-analysis.

Across all 12 included studies, Egger’s regression test ( t = 1.84, df = 10, P = 0.096)[ 20 ] and Begg’s rank correlation test (Kendall’s τ = 0.21, P = 0.31) did not reach statistical significance, providing no strong evidence of publication bias; however, mild funnel plot asymmetry was noted, and given that both tests have low power at k = 12, the possibility of selective reporting cannot be fully excluded [ Figure 2 : Plotted funnel graph].[ 20 ] Primary outcome 2: Manual dexterity (box and block test) Six investigations ( k = 6) involving 175 participants (88 intervention, 87 control) evaluated manual dexterity via the Box and Block Test,[ 14 ] representing a core primary outcome of this review.
