The aim of this study was to examine the effect of upper-limb dominance on the forearm sweating pattern in cerebral palsy (CP). Eight boys with CP (13.1 ± 3.1 years) performed three 10-min bouts of an arm-cranking exercise at 35°C, 50% relative humidity. After the third bout, the sweat drops on both forearms were photographed. Sweat gland density (PD) and the average sweat drop area (DA) were determined. PD was significantly higher (p < .05), whereas DA was significantly lower (p < .05) on the nondominant compared with the dominant forearm. The sweating pattern in spastic CP is influenced by upper-limb dominance.
