What this trial studies

Men with chronic, motor-complete spinal cord injuries at T6 or above and age-matched men without SCI will undergo controlled feeding sessions with low, moderate, high, and ad-libitum meal conditions. Researchers will measure cardiovascular and metabolic responses, including thermogenesis and postprandial changes, over the course of each visit. Participants must be physically inactive and weight-stable, and measurements are taken in person at the research center. The crossover design allows each participant to serve as their own control across meal conditions to directly compare responses.

Who should consider this trial

Good fit: Ideal candidates are men who are at least one year post-injury with motor-complete (AIS A or B) spinal cord injuries at T6 or above who are physically inactive and weight-stable, as well as similar men without SCI for the control group.

Not a fit: Women, people with diabetes, uncompensated thyroid disease, swallowing or GI pathologies, those with relevant food allergies or taking excluded medications, and those with incomplete SCI or ventilator dependence are unlikely to be eligible or to benefit from this protocol.

Why it matters

Potential benefit: If successful, the results could help tailor meal-size and dietary guidance to improve cardiometabolic health in men with high spinal cord injury.

How similar studies have performed: Previous research has shown altered metabolic and thermogenic responses after SCI, but meal-size intervention studies in motor-complete, high-level SCI are limited, so this approach is partly novel.
