EMG and Kinematic analysis of Human Central Pattern Generator Study in a child with Perinatal Thoracic Spinal Cord Injury.

STUDY PURPOSE: The existence of a human spinal locomotor pattern generator, typically referred to as a central pattern generator (CPG), remains controversial. This case study examines the existence of a human CPG by leveraging a unique opportunity to follow the clinical and neurophysiological development of a child with a severe prenatal spinal cord injury (SCI). DATA COLLECTED: The data is collected from two human participants, one participant is non-injured (N154) and one with thoracic (T2) spinal cord injury (P3). Both participants are 4 years old at the time of data collection and male. The Electromyograph (EMG) data is collected via Cometa Pico EMG sensors at a sampling rate of 2000Hz during standing before and after treadmill stepping, stepping on treadmill, performing passive and active cycling (alternating hip/knee flexion/extension) in supine position. The kinematic data is collected using a MaxTRAQ program by analyzing videos of stepping overground and extracting the neck, hip, and knee angles with respect to the vertical axis. The phase duration of flexion/extension or internal/external rotation oscillations in different conditions was measured from participant videos using MaxTRAQ program as well; they denote the duration of flexion/extension or internal/external rotation phase of the left and the right limb, in different conditions.
