The current study will be directed to determine the effect of mechanical vestibular stimulation on fine motor skills and pinch strength in children with hemiparesis. Hemiplegic cerebral palsy causes problems with contraction, sensation, and muscular strength in the upper limbs, and its effective use of muscles for reaching, grasping, releasing, and manipulating objects is often compromised

Inclusion Criteria:

• Children will be included in the study if they fulfil the following criteria:

  1. Diagnosed with hemiparetic cerebral palsy.
  2. Age ranged from 4 to 6 years.
  3. Children with spasticity grades ranged from 1 to 1+ according to Modified Ashworth Scale
  4. Both genders will be included.
  5. The child will be able to follow verbal commands and instructions.

Exclusion Criteria:

• Children will be excluded from the study if:

  1. Any congenital or developmental disorders in addition to hemiplegia cerebral palsy.
  2. Current hospitalization for urgent medical reasons.
  3. Severe mental retardation.
  4. Children having visual or auditory defects.
  5. Children who had Botox application to the upper extremity in the past 6 months or had undergone a previous surgical intervention to the wrist and hand.
