Studies on children with CP—Katusic and Mejaski-Bosnjak [43].

Research Design	Pretest–Post-Test Quasiexperimental Study
JBI level of evidence	2d
Objective(s) stated in the study	To determine the effects of VAT on spasticity and motor function in children with spastic CP (age 3–4)
Sample	13 children (age 3–4) from a daycare center for rehabilitation.
Intervention	VAT once a week for 12 weeks, 20 min (40 Hz sine wave with sinusoidal amplitude variation, 6.8 s between peaks).
Measurements	Pre- and post-12 week treatment GMFM-88, GMFCS standardised assessments, non-parametric Wilcoxon matched pairs test and Pearson c 2-test.
Results	Significant improvement in motor function. There was a significant improvement in total GMFM score (z = 3.17, p = 0.00), as well as on dimension A (lying and rolling, z = 3.05, p = 0.00) and dimension B (sitting, z = 2.80, p = 0.00). There was a significant difference between GMFCS levels of children before and after intervention (df = 6, p = 0.00).
