  • AIS A-D at initial screen, or other non-traumatic spinal cord injury disorders (e.g. multiple sclerosis, ALS, tumors, acute transverse myelitis, etc.)
  • More than 1 year since iSCI to minimize confounds of spontaneous neurological recovery
  • Ability to advance one step overground with or without assistive devices

Who cannot take part

About the trial

What the trial wants to find out

The goal of this study is to examine the effect of repetitive acute intermittent hypoxia on motor learning abilities in able-bodied individuals for subsequent study in individuals with incomplete spinal cord injury.

The 3 groups in the trial

  • Repetitive Acute Intermittent HypoxiaTreatment being tested

    5 consecutive days of 15, 1.5 min episodes at 9% O2 (AIH) alternating with 21% O2 at 1 min intervals

    Treatment: Acute Intermittent Hypoxia

  • SHAM Acute Intermittent HypoxiaSham treatment, for comparison

    5 consecutive days of 15, 1.5 min episodes at 21% O2 (SHAM AIH) alternating with 21% O2 at 1 min intervals

  • ControlNo study treatment, for comparison

    The control group received no AIH exposure.
