Objective To determine the degree to which a high-frequency, low-magnitude vibration signal emitted by a floor-based platform transmits to the distal tibia and distal femur of children with spastic cerebral palsy (CP) during standing. Design Cross-sectional study. Setting University research laboratory. Participants Children with spastic CP who could stand independently (n=18) and typically developing children (n=10) (age range, 412y) participated in the study (N=28). Interventions Not applicable. Main Outcome Measures The vibration signal at the high-frequency, low-magnitude vibration platform (approximately 33Hz and 0.3g), distal tibia, and distal femur was measured using accelerometers. The degree of plantar flexor spasticity was assessed using the Modified Ashworth Scale. Results The high-frequency, low-magnitude vibration signal was greater (P<.001 at the distal tibia than platform in children with cp vs .29 and controls .24 although vibration signal was also higher femur p it lower degree of spasticity negatively related to transmitted> Conclusions A high-frequency, low-magnitude vibration signal from a floor-based platform was amplified at the distal tibia, attenuated at the distal femur, and inversely related to the degree of muscle spasticity in children with spastic CP. Whether this transmission pattern affects the adaptation of the bones of children with CP to high-frequency, low-magnitude vibration requires further investigation. |
