Single joint perturbation during gait: Preserved compensatory response pattern in spinal cord injured subjects

Single joint perturbation during gait: preserved compensatory response pattern in spinal cord injured subjects.

OBJECTIVE Responses to afferent input during locomotion are organized at the spinal level but modulated by supraspinal centers. The study aim was to examine whether supraspinal influences affect the behavior of complex electromyographic (EMG) responses to single limb perturbations during walking. METHODS Subjects with motor-complete (MCSCI), motor-incomplete spinal cord injury (MISCI), and no...

Neural Prostheses for Spinal Cord Injured Subjects

A functional electrical stimulation system with surface electrodes and four stimulation channels was developed. The proposed system was used to design two neural prostheses for spinal cord injured subjects and stroke subjects. One prosthesis was used to restore a grasping function in high lesioned tetraplegic subjects. The other prosthesis was used to eliminate the ‘drop foot’ problem in incomp...

Artificial gait in complete spinal cord injured subjects: how to assess clinical performance.

OBJECTIVE Adapt the 6 minutes walking test (6MWT) to artificial gait in complete spinal cord injured (SCI) patients aided by neuromuscular electrical stimulation. METHOD Nine male individuals with paraplegia (AIS A) participated in this study. Lesion levels varied between T4 and T12 and time post injured from 4 to 13 years. Patients performed 6MWT 1 and 6MWT 2. They used neuromuscular electri...

Electrophysiological Markers for Neuropathic Pain in Spinal Cord Injured Subjects

Assessment of skin blood content and oxygenation in spinal cord injured subjects during reactive hyperemia.

This study was undertaken to determine whether the reactive hyperemia response following ischemia in spinal cord injured (SCI) individuals is different from that which occurs in able-bodied (AB) individuals. The reactive hyperemia response was produced by applying a pressure of 150 mmHg for 300 s, 600 s, and 900 s to the skin over the greater trochanter in 10 SCI and 10 AB subjects using a comp...
