About

Spasticity is one of the most common features in children with cerebral palsy (CP) and is evident in the majority of CP types such as hemiplegia, diplegia, quadriplegia, etc. Children with spastic upper motor neuron lesions often experience difficulties with muscle tone and movement, impacting their functional abilities and quality of life. Conventional treatments such as physical therapy and medication have demonstrated positive effects in the management of spasticity. However, alternative interventions like whole body vibration (WBV) have gained attention due to their potential to modulate muscle tone and improve functional outcomes. WBV involves the transmission of mechanical vibrations to the whole body or specific body parts. These vibrations stimulate sensory receptors and elicit muscular responses, potentially leading to improved muscle tone regulation and reduced spasticity.

Full description

Several studies have investigated the effects of WBV on spasticity management. These studies have reported various outcomes, providing valuable insights into the potential benefits of this intervention. Previous studies showed an immediate reduction of spasticity of the calf muscle, increased the range of the popliteal angle, and improved step length, step width, foot angle, and walking speed.

The current study seeks to address some of the limitations observed in previous research. It employs a randomized controlled trial design with a predetermined sample size, enhancing the statistical power and generalizability of the findings. The intervention group will receive supervised upper limb exercises using WBV, while the control group will receive conventional therapy. By comparing these two groups, the study aims to provide more robust evidence regarding the specific effects of WBV on muscle tone and spasticity. Furthermore, the current study will utilize standardized assessment tools to measure muscle tone, spasticity, and functional outcomes pre-and post-intervention. This will allow for a comprehensive evaluation of the effects of WBV on spasticity management, encompassing both objective measures and functional improvements.

56 participants in 2 patient groups

regular physical therapy group

Active Comparator group

Description:

this group will receive regular physical therapy 3 -5 times per week. this program will be designed according to the needs of each child. strength, stretch, facilitation, splinting, coordination, and functional exercises are examples of the components of the programs.

Treatment:

Other: standard physical therapy

whole body vibration

Experimental group

Description:

in addition to the regular exercises, selected arm exercises will be performed while the child is under whole-body vibration. using (Galileo® MED 25 TT, Germany; 2021 model) with the following parameters: * WBV session duration: 10 minutes (rest periods can be incorporated * frequency: 12 Hz * Amplitude: 2 (fixed) * duration of each exercise: 2-3 minutes
