Actigraph assessment for measuring upper limb activity in unilateral cerebral palsy.
Beani E, Maselli M, Sicola E, Perazza S, Cecchi F, Dario P, Braito I, Boyd R, Cioni G, Sgandurra G. Beani E, et al. J Neuroeng Rehabil. 2019 Feb 22;16(1):30. doi: 10.1186/s12984-019-0499-7. J Neuroeng Rehabil. 2019. PMID: 30795810 Free PMC article.
METHODS: Fifty children with UCP and 50 TD subjects were assessed with AHA while wearing ActiGraphs GT3X+ on both wrists. The mean activity of each hand (dominant and non-dominant, MA(DH) and MA(NDH), respectively) and the asymmetry index (AI) were calculated. Two linear m …
