Breathing Low Oxygen to Enhance Spinal Stimulation Training and Functional Recovery in Persons with Chronic Spinal Cord Injury: The BO2ST Trial

Overview

Body

Walking recovery is a key goal after spinal cord injury (SCI). While some patients experience spontaneous recovery due to preserved neural circuits, many struggle to achieve independent ambulation, and those who do often face persistent deficits. There is growing consensus that a single approach is insufficient to overcome these challenges, prompting the need for combined interventions. 

BO2ST Description

The goal of this double-blind, placebo-controlled, block-randomized clinical trial is to investigate the efficacy and potency of daily acute intermittent hypoxia (AIH) combined with transcutaneous electrical spinal stimulation (tSTIM) and skill-based walking practice. We hypothesize that the combination of AIH, tSTIM, and walking practice will boost the efficacy of training-related gains without triggering maladaptive changes.
