: The American Spinal Injury Association (ASIA) Impairment Scale is described in the background section below.
Spinal cord injury can (SCI) cause various degrees of neurological impairment depending on the location and severity of the injury.
Subjects with thoracic (T4 to T11) motor-complete SCI, mean age of 28.8 years, and mean duration post-injury of 3.8 years underwent 32 functional neuromuscular stimulation ambulation training sessions using the Parastep I System.
The brain, through the UMN, exerts an inhibitory influence on the LMN so that they do not become hyperactive to local stimuli.
The cell bodies of LMN are located in the central gray matter throughout the entire length of the spinal column, and their axons extend out via the spinal nerve roots and peripheral nerve branches to innervate skeletal muscles throughout the body.
The authors concluded that the Parastep I System enabled persons with thoracic-level SCI to stand and ambulate short distances but with a high-degree of performance variability across individuals.
Furthermore, Graupe and Kohn (1998) reported that about 400 patients have used the Parastep I System and essentially all achieved standing and at least 30 feet of ambulation, with a few reaching as much as 1 mile at a time.
