Clinical telemetry of EMG and temporal information during gait.

Abstract

Multichannel telemetry has formed an integral part of the clinical assessment of children's walking problems. EMG signals and temporal information from foot switches are transmitted from a small belt-pack unit which provides almost complete freedom of movement for the child. Although patients with various crippling diseases have been studied, the investigation of problems resulting from cerebral palsy has been most valuable clinically. The effects of orthopaedic surgery to release or transfer muscles can be asssessed more positively and the causes of some unexplained gait patterns can be investigated more thoroughly.
