Paired neck and lower‑back spinal stimulation to help standing and walking after spinal cord injury
Cervical and Lumbosacral Transspinal Stimulation to Reconnect the Injured Human Spinal Cord
This trial will test whether non‑invasive electrical stimulation over the neck and lower back, alone or combined with robotic step training, can help people with incomplete spinal cord injury improve standing and walking.

What this trial studies
This pilot trial applies non‑invasive transspinal stimulation over the cervical and lumbosacral enlargements, delivered either at rest or during robotic (Lokomat) assisted step training, to adults with chronic incomplete spinal cord injury. Investigators will record neurophysiological measures (H‑reflexes and transspinal evoked potentials) and analyze joint coordination and muscle synergies during treadmill stepping, with comparisons to healthy control subjects for mechanistic insight. The study is designed to establish safety and preliminary efficacy signals and to explore how paired cervical and lumbosacral stimulation may augment locomotor rehabilitation. Findings will inform whether this non‑invasive combinatorial approach could be advanced to larger multi‑site trials and routine clinical use.
Who should consider this trial
Good fit: Adults with chronic (>6 months) incomplete spinal cord injury (AIS B, C, or D), lesion above T10, measurable soleus and FCR H‑reflexes, stable medical status, and ability to attend visits are ideal candidates.
Not a fit: People with complete spinal cord injuries, lower motor neuron lesions, supraspinal lesions, or who lack measurable H‑reflexes or flexible ankle joints are unlikely to benefit from this protocol.
Why it matters
Potential benefit: If successful, this approach could improve standing and walking function and related autonomic or motor control outcomes for people with incomplete spinal cord injuries.
How similar studies have performed: Prior small studies of transcutaneous/transspinal stimulation have shown promising changes in muscle activation and stepping, but paired cervical plus lumbosacral stimulation combined with robotic gait training is a relatively novel combinatorial approach that requires confirmation.
Eligibility criteria
Show full inclusion / exclusion criteria
Inclusion Criteria: * Willingness to comply with all study procedures and availability for the duration of the study. * Ability to understand the consent form and sign the consent form. * In good general health as evidenced by medical history. * Diagnosed with incomplete SCI (AIS B, C, D). * Bone mineral density of the hip (proximal femur) T-score \<3.5 SD from age- and gender-matched normative data. * Lesion above thoracic (T) 10 to ensure absent lower motoneuron lesion. * The presence of soleus and FCR H-reflexes. * Absent permanent ankle joint contractures prevent passive or active ankle movement because corticospinal and spinal excitability is based on the ankle angle. The ankle straps of the Lokomat also require flexible ankle joints. * A diagnosis of first time SCI due to trauma, vascular, or orthopedic pathology. * Time after SCI of more than 6 months. * Stable medical condition without cardiopulmonary disease or cognitive impairment. Exclusion Criteria: * Supraspinal lesions. * Neuropathies of the peripheral nervous system. * Significant degenerative neurological disorders of the spine or spinal cord. * Diagnosed with AIS A. * Presence of pressure sores. * Advanced urinary tract infection. * Neoplastic or vascular disorders of the spine or spinal cord. * Participation in an ongoing research study or new rehabilitation program. * Pregnant women or women who suspect they may be or may become pregnant will be excluded from participation because the risks of thoracolumbar stimulation to the fetus are unknown. * People with cochlear implants, pacemakers, implanted infusion device, and/or implanted stimulators of any type and purpose will be excluded to avoid their malfunction due to stimulation.
