Specifically, this study is being done to determine if pre-treatment with intermittent hypoxia can enhance the beneficial effects of upper limb training on the restoration of limb function in persons with spinal injury.\n\nThis is a blinded study, which means that the subject will not know which treatment they are receiving. They will either receive intermittent periods of low oxygen (hypoxia) or a session composed of only normal room air. They will be randomly assigned to a treatment based on chance. Neither the subject nor the researcher chooses the assigned group. They will have an equal chance of being in either group.\n\nThe participant will receive a daily 5-day intervention with either acute intermittent hypoxia (AIH) therapy or room air, either alone or coupled with task-specific training, on upper extremity function in individuals with chronic, incomplete SCI. This will be preceded by a baseline testing visit prior to the intervention, and followed by a 4 week follow up period to assess the effects of the interventions over time.\n\nThe total duration of participation in the study intervention protocol is 1 week.
