简要总结
The overall objective of this project is to investigate the effectiveness of daily acute intermittent hypoxia therapy (dAIH), coupled with massed practice training, to improve upper-extremity function in individuals with chronic incomplete cervical SCI.
详细描述
Specific Aim 1: Evaluate the effectiveness of a combined intervention utilizing dAIH and massed practice upper extremity training on arm and hand function in individuals with incomplete tetraplegia.
Specific Aim 2: Evaluate the effectiveness of a combined intervention utilizing dAIH therapy and robotic rehabilitation device-administered upper-extremity training on arm and hand function in persons with incomplete tetraplegia.

入选标准
- •History of a non-progressive spinal cord injury, at or below C2, and at or above T
- •Between the ages of 18 - 75 years.
- •Time since injury must be at least 6 months if the injury was traumatic in nature. If the spinal cord injury is non-traumatic, participants must meet at least the initial 6-month criteria in addition to either no regression in symptoms for at least two years, per self-report or per medical monitor discretion.
- •Demonstrate voluntary motor activation in hand muscles, with a score of at least a 2 on at least one of the Prehension Ability grasp patterns of the GRASSP assessment (cylindrical grasp, lateral key pinch, and tip to tip pinch), on at least one upper extremity.
- •Ability to understand and the willingness to sign an informed consent.
- •At least a 10% change in isometric elbow strength above baseline, after a single bout of Acute Intermittent Hypoxia (AIH), during screening.
排除标准
- •Diagnosed with any of the following medical conditions: congestive heart failure, cardiac arrhythmias, uncontrolled hypertension, uncontrolled diabetes mellitus, chronic obstructive pulmonary disease, emphysema, severe asthma, previous myocardial infraction, or known carotid/intracerebral artery stenosis.
- •Women who are currently pregnant/nursing or planning on becoming pregnant.
- •Individuals with a tracheostomy or who utilize mechanical ventilation.
- •Individuals who are currently enrolled in another interventional research study or in therapy related to upper extremity function.
- •Participants will be excluded if they have had a botulinum toxin injection to upper extremity musculature within the last 3 months. Participants will need to refrain from upper extremity botulinum toxin injections for the duration of the study. If participants wean off antispasticity medications to successfully complete the responsiveness to AIH screening session, they will need to refrain from the medications for the duration of the study.
- •Documented sleep apnea.
- •Orthopedic injuries or surgeries that would impact an individual's ability to use the upper extremity.
- •Traumatic brain injury or other neurological conditions that would impact the study.
- •Blood hemoglobin levels less than 10g/dL.
研究组 & 干预措施
No training with dAIH
Once fitted with the mask, initial recordings of heart rate, blood pressure, and arterial oxygen saturation (SpO2) will be taken. The sequence of hypoxia will consist of 60- 90 seconds of 9-10% O2 (FiO2 0.09), alternating with 60- 90 seconds of 21% O2 (normoxic air FiO2 0.21). The delivery of hypoxia and normoxic air mixtures will be repeated up to 18 times per session each, for a total of up to 45 minutes, to maintain SpO2 at 80-90%.
Hearth rate and pulse oximetry will be continuously monitored throughout, and recording will be taken at each alteration in sequence. Blood pressure will be taken upon completion of the total sequence

Massed practice training with dAIH
Seek to address gross upper extremity movements, grip and pinch strength, and coordination.The ultimate goal of the session is to achieve a total of 300 repetitions during training.

GRASSP
时间窗: up to 3 months
The Graded Redefined Assessment of Strength, Sensibility and Prehension (GRASSP) is an extensive and validated impairment and functional measure which is able to detect subtle neurologic changes in individuals with spinal cord injury. Specifically, it evaluates the domains of sensation, strength, quality of different grip patterns and the ability to complete a variety of functional tasks.
