Plyometric training includes muscle contraction that moves rapidly from the eccentric to the concentric phase of movement while using proper biomechanics. It is an effective neuromuscular stimulus that can improve motor functions of children with cerebral palsy. In plyometric training, muscles exert maximum force in short intervals of time, with the goal of increasing power.

Commercially available video games have been used for a wide range of clinical populations with generally positive clinical outcomes. They have been shown to be active enough to provide an increase in energy expenditure and physical activity in children with cerebral palsy. Furthermore, an early case study showed improvements in visual-perceptual processing, balance, and mobility in a child with cerebral palsy.


Ethics Statement This study was approved by the Institutional Review Board of the Faculty of Physical Therapy, Cairo University, Egypt and strictly adhered to the criteria proclaimed in the latest version of the Declaration of Helsinki code of ethics. Children's participation will be commissioned by asking their legal guardian to sign a consent form prior to data collection.

A convenient sample of ambulant children with unilateral CP will be recruited from the Out-patient Clinic Faculty of physical therapy, Cairo University and outpatient physical therapy clinics.

Sample size estimation To avoid a type II error, a preliminary power analysis (power =0.8, α=0.05, effect size =0.5) determined a sample size of 28 for this study. Accordingly, 35 children who met the eligible criteria will be included in the current study for possible dropouts.

Randomization The randomization process will be performed using sealed envelopes. The investigator will prepare 35 sealed envelopes that contain a piece of paper indicating whether each participant was in the Wii group (receive Wii training for 45 minutes) or plyometric group (receive plyometric exercises for 45 minutes). The randomization process will be carried out by a registration clerk who was not involved in any part of the study.
