This idea stems from animal studies on respiration, in which investigators showed that mild AIH improves breathing in rats with spinal injuries as well as studies involving spinal cord stimulation. These studies showed that AIH induces plasticity, strengthening neural connections by increasing the production of key proteins and improving the sensitivity of spinal cord circuitry. Additional studies have shown that tSTIM may enhance function and strength for people with spinal cord injuries. The ultimate goal of this research is to assess if combining AIH and tSTIM with walking training can enhance individuals walking training greater than just AIH or tSTIM. By using low oxygen as a pre-treatment to tSTIM during walking training, functional independence and quality of life for servicemen and civilians may improve.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '70 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* 18 to 70 years of age\n* medically stable with medical clearance from study physician to participate\n* SCI at or below C2 (phrenic sparing) and at or above L2 with at least some sensory or motor function preserved below the neurologic level\n* non-progressive etiology of spinal injury\n* American Spinal Injury Association (ASIA) scores of C-D at initial screen\n* ambulatory (able to complete the 10-meter walk test without support from another person)\n* chronic injury (define as \\> 12 months post-injury) to avoid potential for spontaneous neurological plasticity and recovery\n\nExclusion Criteria:\n\n* severe concurrent illness or pain, including unhealed decubiti, severe neuropathic or chronic pain syndrome, severe infection (e.g., urinary tract), hypertension, cardiovascular disease, pulmonary disease, severe osteoporosis, active heterotopic ossification in the lower extremities, severe systemic inflammation\n* \\< 24 on Mini-Mental Exam\n* severe recurrent autonomic dysreflexia\n* history of severe cardiovascular/pulmonary complications including hypertension (systolic blood pressure \\> 150 mmHg)\n* pregnancy because of unknown effects of AIH or tSTIM on a fetus (individuals of childbearing potential will not otherwise be excluded)\n* botulinum toxin injections in lower extremity muscles within the prior three months\n* history of tendon or nerve transfer surgery in the lower extremity\n* untreated severe sleep-disordered breathing characterized by uncontrolled hypoxia and sleep fractionation that may impact the outcome of this study.\n* active implanted devices (e.g., intrathecal baclofen pump)\n* receiving concurrent electrical stimulation\n* motor threshold evoked by transcutaneous spinal stimulation \\>200 mA'}, 'identificationModule': {'nctId': 'NCT05563103', 'acronym': 'BO2ST', 'briefTitle': 'Combination Therapy to Improve SCI Recovery.', 'organization': {'class': 'OTHER', 'fullName': 'Spaulding Rehabilitation Hospital'}, 'officialTitle': 'Breathing Low Oxygen to Enhance Spinal Stimulation Training and Functional Recovery in Persons With Chronic SCI: The BO2ST Trial', 'orgStudyIdInfo': {'id': '2022P002036'}, 'secondaryIdInfos': [{'id': 'W81XWH-22-1-0998', 'type': 'OTHER_GRANT', 'domain': 'US Dept. of Defense'}]}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'AIH + Walking Training with transcutaneous spinal stimulation (WALKtSTIM)', 'description': 'Acute Intermittent Hypoxia will be used as a pretreatment before walking training paired with transcutaneous spinal cord stimulation.', 'interventionNames': ['Other: Daily acute intermittent hypoxia', 'Other: Walking + tSTIM']}, {'type': 'SHAM_COMPARATOR', 'label': 'Sham + WALKtSTIM', 'description': 'Sham acute intermittent hypoxia will be used as a pretreatment before walking training paired with transcutaneous spinal cord stimulation.', 'interventionNames': ['Other: Room air (SHAM)', 'Other: Walking + tSTIM']}, {'type': 'SHAM_COMPARATOR', 'label': 'AIH + Walking Training with sham transcutaneous spinal stimulation (WALKtSHAM)', 'description': 'Acute Intermittent Hypoxia will be used as a pretreatment before walking training paired with sham transcutaneous spinal cord stimulation.', 'interventionNames': ['Other: Daily acute intermittent hypoxia', 'Other: Walking + Sham transcutaneous spinal stimulation (tSHAM)']}], 'interventions': [{'name': 'Daily acute intermittent hypoxia', 'type': 'OTHER', 'description': 'Each participant will be exposed to 8 sessions of daily acute intermittent hypoxia via air generators over the span of two weeks.
