NCT04472442 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 35

Last updated 2024-10-17

No results posted yet for this study

Summary

The central hypotheses are that HIT combined with AIH results in: 1) greater locomotor gains as compared to HIT alone; 2) improvements in gait quality and motor coordination during walking, and 3) changes in measures of community participation and integration.

Conditions

  • Brain Injuries

Interventions

PROCEDURE

Intermittent hypoxia

Acute intermittent treatment (AIH) will be initiated using an oxygen generator (Model HYP-123, Hypoxico Inc, New York, NY, and participants will be seated comfortably and fitted with a non-rebreather mask. AIH (using 9% O2) will be provided in 60 s intervals and repeated 15 times with alternating 60 s intervals of normoxia (21% O2). Continuous pulse oximetry (Masimo 7, Irvine CA) will be monitored to ensure oxygen saturation of 82-85%. Signs and symptoms of distress with AIH exposure will be noted throughout, with HR and blood pressure taken every 3-5 minutes and documented. High-intensity training will then be performed (40 min of walking training up to 70-80% maximum heart rate within 1 hr).

PROCEDURE

Sham hypoxia

Sham acute intermittent treatment (sham AIH) will be initiated using an oxygen generator (Model HYP-123, Hypoxico Inc, New York, NY, and participants will be seated comfortably and fitted with a non-rebreather mask. Sham AIH (using 20% O2) will be provided in 60 s intervals and repeated 15 times with alternating 60 s intervals of normoxia (21% O2). Continuous pulse oximetry (Masimo 7, Irvine CA) will be monitored to ensure oxygen saturation of 82-85%. Signs and symptoms of distress with AIH exposure will be noted throughout, with HR and blood pressure taken every 3-5 minutes and documented. High-intensity training will then be performed (40 min of walking training up to 70-80% maximum heart rate within 1 hr).
