Spinal zap plus breathing drills may boost lung power after paralysis
NCT ID NCT06019949
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a gentle electrical stimulation of the spinal cord, combined with breathing exercises, can improve lung function in people with chronic spinal cord injury. About 36 adults will be split into three groups: breathing training alone, stimulation alone, or both together. The goal is to see if the combination leads to stronger breathing muscles and better lung health.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * At least 18 years old; * stable medical condition; * no painful musculoskeletal dysfunction, unhealed fracture, contracture, pressure sore or urinary tract infection that might interfere with respiratory training or stimulation; * no clinically significant depression, psychiatric disorders or ongoing drug abuse; * non-progressive SCI (no negative change in the neurological level and motor-completeness assessed during screening when compared to the neurological status assessed at 6-mo period after injury or at least 6 months prior to the screening), non-ventilator dependence, motor-complete SCI according to the American Spinal Injury Association Impairment Scale (AIS) grade "A" or "B" above T5 spinal level; * sustained SCI at least 12 months prior to entering the study; * compared to the normative values for healthy population, at least 15%-deficit in pulmonary function outcomes (FVC and FEV1) as detected by screening spirometry. Exclusion Criteria: Participants will be excluded from the study if there is a presence of * major pulmonary or cardiovascular disease, * ventilator dependence, * endocrine disorders, * malignancy, * marked obesity, * deep vein thrombosis, * HIV/AIDS-related illness, * secondary hypotension (anemia, hypervolemia, endocrine and neurological diseases), * major esophageal/gastrointestinal problem or other major medical illness contraindicated for respiratory training or testing. During screening, the potential participant will be asked whether she is pregnant or planning to become pregnant during the study period. Pregnant women are excluded from this study, as the risk to the fetus is unknown. No pregnancy test or birth control regimen will be required.
