The Effects of Electrical Stimulation Gait Training on Walking and Posture for Children With Cerebral Palsy

Completed · Not applicable

Conditions studied: Cerebral Palsy

In brief

This proposal is designed to achieve the following specific aims and will test the associated hypotheses: AIM 1: To compare walking ability, standing posture, gait initiation and functional standing and stepping of twenty children with typical development to that of twenty children with spastic diplegia or hemiplegia, CP. Hypotheses * Children with CP will demonstrate impaired coordination as compared to children of typical development. In addition, children with CP will demonstrate inappropriate foot contact area, decreased velocity and step length as compared to children of typical development. * Children with CP will demonstrate impaired postural control as compared to children of typical development. * Children with CP will demonstrate an impaired gait initiation motor program as compared to children with typical development. * Children with CP will take more time to complete the timed up and go test and demonstrate decreased reaching distances in the functional reach test as compared to children of typical development. AIM 2: Using a single-blinded, randomized, controlled study design, to assess the ability of a 12-week at-home electrical stimulation gait training program to improve walking ability, standing posture, gait initiation, functional standing and stepping, and satisfaction with walking ability for a group of 10 children with spastic diplegia or hemiplegia CP as compared to a group of 10 children with spastic diplegia or hemiplegia CP who undergo a 12-week at-home gait training program without electrical stimulation. Hypotheses * The ES gait training group will demonstrate improved joint coordination as compared to the group undergoing a gait training program without ES. The ES gait training group will demonstrate improved foot contact area, increased self-selected walking velocity and greater step length as compared to the group undergoing a gait training program without ES. * The ES gait training group will demonstrate improved postural control as compared to the group undergoing a gait training program without ES. * The ES gait training group will demonstrate improved gait initiation as compared to the gait training group without ES. * The ES gait training group will demonstrate decreased times on the Timed Up and Go and an increase in functional reach as compared to the group undergoing a gait training program without ES. * The ES gait training group will demonstrate greater satisfaction and self-perceived performance on everyday tasks related to walking function and posture as measured by the COPM compared to the group that undergoes a gait training program without ES.

Who can join

Age: 7 and older, up to 14. Sex: any. Healthy volunteers: accepted.

You may qualify if…

A diagnosis of spastic diplegia or spastic hemiplegia or a history of typically development for the measurement only group.
A Level I, II or III gross motor function classification.
The subject classified as Level I or II is able to walk indoors and outdoors and climb stairs holding onto a railing but experiences limitations walking in crowds or confined spaces. Subjects classified as Level III's need to walk with assistive devices and have limitations in their ability to ambulate outdoors and in the community. Children have at best only minimal ability to perform gross motor skills such as running and jumping.
Male or female between the ages of 7 and 14 years of age.
Family able and willing to provide adequate care to electrodes and electrode sites.
Must be orthopedically cleared without imminent risk of hip subluxation or dislocation and no significant scoliosis.
Seizure-free.
Visuoperceptual skills and cognitive/communication skills sufficient to follow multiple step commands and to attend to tasks associated with data collection.
Absence of severe tactile hypersensitivity in the lower extremities.
Willingness to stay in Philadelphia for extended period of time to train and return for follow-up data.
Written, informed consent.
One year post soft tissue releases to the lower extremities.
Passive range of motion of lower extremity joints: <10 degrees contracture of hip in extension as measured by the Thomas Test; <5 degrees knee flexion contracture and popliteal angle <45 degrees; at least 0 degrees of ankle dorsiflexion with knee extended and foot in varus.

You may not qualify if…

Children with "mixed" types of CP (ie:Athetosis) or other movement disorders (ie:Ataxia).
Allergy or sensitivity to non-latex tape placed in the skin
Female children cannot be pregnant. A pregnancy test will be given if it is possible that the child can become pregnant, to ascertain whether or not the child is pregnant.
