Different Postures and Energy Expenditure in Children with Cerebral Palsy
[Source: Your Therapy Source]
Research was published comparing the muscle activation and energy expenditure of different postures in children and adolescents with cerebral palsy. Energy-expenditure and muscle activity were measured during lying supine, sitting with support, sitting without support, and standing in 19 subjects with cerebral palsy (GMFCS- E&R Levels I-V). Using indirect calorimetry and surface electromyography, the following results were recorded:
1. mean energy expenditure was >1.5 METs (sedentary behavior is 1.5 METs or less) during standing for all GMFCS-E&R levels
2. a nonsignificant trend for greater muscle activation was recorded for all postures with less support
3. a standing posture resulted in significantly greater muscle activation compared to resting but only in the children classified at GMFCS-E&R level III.
The researchers concluded that across all GMFCS-E&R levels, children and adolescents with cerebral palsy had elevated energy expenditure during standing that exceeded the sedentary threshold of 1.5 METs. The researchers findings suggest that changing a child’s position to standing may help to increase light activity time and decrease long periods of sedentary behavior.
