Brief Summary:

Cerebral palsy (CP) is the most common neuromuscular disorder among children, resulting from a non-progressive injury during early brain development which leads to impairment of movement and posture.

Muscle weakness and spasticity associated with CP limit the joint range of motion and negatively impact ambulatory ability. Most ambulatory children with CP are prescribed with ankle-foot orthoses (AFOs) to improve ankle position and stability and to maintain muscle range. Nevertheless, AFOs may also restrict desired motions and may exacerbate muscle weakness and atrophy.

During the last years a novel method is being used for treating upper motor neuron drop foot, by means of dynamic orthoses, namely Functional Electrical Stimulation (FES).

These FES devices cause dorsiflexion of foot by stimulating the peroneal nerve and activating the tibialis anterior muscle. Most of the studies of FES devices were conducted on adult population. These studies showed improvement in laboratory and functional gait parameters. There are relatively few studies on children with hemiplegic or diplegic CP with favorable results. There is no solid evidence whether the improvements seen in laboratory setting of children with CP, are reflected on functional ambulation in daily life. In addition, there are no defined parameters which could predict the response to FES among those children.

The aim of this study is to determine whether using FES device (WalkAide; Innovative Neurotronics, Austin, TX, USA) improves daily motor function and gait parameters in children with spastic hemiplegic or diplegic CP. additionally, we aim to define clinical and biomechanical parameters that can predict a favorable response to using the FES device.

Arm Intervention/treatment
Experimental: WalkAide Device: WalkAide

Patiants with hemiplegic or asymmetric diplegic CP will use WalkAide device for 4 months .First month for adjustment and three months of daily using of the device.

For each patient two assessments will be conducted: at baseline and at post-intervention follow-up.

During the assessments each child will go through:

A. Medical interview and neurological and physical therapist examination. B. Motor function tests: "6 min walk test", Gross motor function measure (GMFM) ,"Timed up and down stairs test" (TUDS), walking on a ramp ,with and without the FES device.

C. Gait analysis test with and without FES device. D. Parents will be requested to complete questionnaires on the frequency of falling.

E. On the second assessment parents wiil be requested to complete a questionnaire about the compliance to the FES.

Primary Outcome Measures :
  1. "Six min walk test" [ Time Frame: 4 months ]
    This test measures the distance that a patient can quickly walk on a flat, hard surface in a period of 6 minutes (Maher C et al ,2008)

  2. "Gross motor function measure" (GMFM) section E [ Time Frame: 4 months ]
    The Gross Motor Function Measure (GMFM) is a clinical tool designed to evaluate change in gross motor function in children with cerebral palsy. Section E evaluate walking, running and jumping skills (Rosenbaum PL et al, 2008)

  3. "Timed up and down stairs test" [ Time Frame: 4 months ]
    This test measures time going up and down 14-step flight of stairs (Zaino CA et al 2004)

  4. Ankle angle at initial contact [ Time Frame: 4 months ]
    measured by "Gait analysis laboratory"

  5. Peak dorsiflexion angle in swing phase [ Time Frame: 4 months ]
    measured by "Gait analysis laboratory"
