Summary

This study aims to assess the feasibility of a visual feedback system designed to augment treadmill-based gait training for children with gait disturbances related to hemiplegic cerebral palsy. The visual feedback uses data from knee and hip joint movements to represent the position of the foot ahead of or behind the body during walking. This study will test eight children with hemiplegic cerebral palsy who have short step lengths related to atypical knee and hip motions when the foot contacts the ground (initial contact). The study will examine walking adaptations in response to the new visual feedback system and compare differences in response and user experience between two variants of the new design. In a single visit, participants will undergo a gait retraining protocol using the dual joint visual feedback (DJVF) system. Hip and knee flexion angles of the paretic (weaker) side will be collected, analyzed, and compared during baseline walking and while responding to the two feedback variants. Muscle firing patterns will be studied using electrodes placed on key lower limb muscles. Study participants will be asked to report their experience and preferences following the gait retraining protocol. The study findings will be used to further refine the DJVF system in preparation for future studies.

Conditions

  • Hemiplegic Cerebral Palsy

Interventions

DEVICE

Dual Joint Visual Feedback without Scoring

Participants will walk on the treadmill while given instantaneous anterior and posterior foot position and immediate scoring information using the DJVF interface. A pediatric physical therapist will provide (1) verbal encouragement and redirection of attention to the task as needed (2) verbal cueing to assist if difficulty in interpreting the feedback and appropriate modification is noted.

DEVICE

Dual Joint Visual Feedback with Scoring

Participants will walk on the treadmill using the same DJFB with additional visual cumulative scoring on their performance. A pediatric physical therapist will provide (1) verbal encouragement and redirection of attention to the task as needed (2) verbal cueing to assist if difficulty in interpreting the feedback and appropriate modification is noted.
