Summary

This study compared the efficacy of therapeutic ultrasound (US) and whole-body vibration (WBV) as adjuncts to a standardized passive stretching regimen on improving knee joint range of motion (ROM) and functional capacity in children with hemiplegic cerebral palsy (HCP).

Detailed description

Sixty children with HCP, aged 4-6 years, were randomly assigned to one of two groups. Both groups received passive stretching of the hamstrings and plantar flexors three times per week for twelve weeks. The control group (US group) received therapeutic ultrasound prior to stretching, while the research group (WBV group) performed exercises on a vibrating platform before stretching. Active knee extension ROM was measured with a digital goniometer, and functional ability was assessed using the Gross Motor Function Measure-88 (GMFM-88) at baseline and post-intervention.

Conditions

• Cerebral Palsy (CP)

Interventions

Type	Name	Description
DEVICE	ultrasound	Received continuous ultrasound (1 MHz, 1.0 W/cm², 5 min per hamstring) using a Chattanooga Intelect Mobile 2 unit with a medium-sized transducer head and coupling gel
DEVICE	whole body vibration	Performed exercises on a Power Plate Pro 5 vibration platform. Parameters were set to a frequency of 20 Hz and a fixed amplitude of 2 mm (peak-to-peak displacement). The child maintained a semi-squat posture (approximately 30 knee flexion) for two 5-minute bouts separated by a 1-minute rest.
