简要总结
The goal of this observational study is to determine if nerve transfer surgeries improve upper extremity function and quality of life in patients with a high level cervical spinal cord injury.
Participants will:
- undergo standard of care pre- and post-op testing and study exams
- complete pre- and post-questionnaires
- undergo standard of care nerve transfer surgeries
- follow-up with surgeon at 6/12/18/24/36 and potentially at 48 months
- attend therapy at local therapist for up to 2 years postop.
详细描述
Restoration of function in patients with high tetraplegia has been an elusive clinical challenge. There is a critical need to find an effective reconstructive therapy/procedure which improves the upper extremity function in patients with high tetraplegia. One pure motor nerve - spinal accessory nerve (SAN) remains a viable donor in high tetraplegia patients to successfully restore elbow flexion or extension. Elbow function can provide profound independence in mobility, ventilator management and may broaden the application of assistive therapies. The two objectives of this study are: * Determine if SAN nerve transfer surgery can improve the reinnervation of bicep or tricep muscles in high tetraplegia patients. * Determine if SAN nerve transfer surgery can reanimate upper arm function and improve functional independence in patients with high tetraplegia. Study Activities (including standard of care (SOC)) * Electrodiagnosis pre-op (SOC) * Upper extremity maximum muscle testing (SOC) * Questionnaires (SOC and study-related (SR)) * Exams by a study therapist (SR) * Neurological exam - ISNCSCI - (SOC) * Nerve Transfer Surgery to be determined by surgeon (SOC) * Follow-up visits with surgeon at 6/12/18/24/36 and potentially 48 months * post-op electrodiagnostic testing (SR) * post-op upper extremity maximum muscle testing (SOC) * post-op questionnaires * post-op therapy exams (SR)

结局指标
主要结局
Motor strength in medical research council grade (MRC)
时间窗: 36-48 months post-surgery
Change in baseline to 36-48 Months post-surgery. The manual muscle testing is a reliable measure of motor strength when assessed by a trained examiner. Scores range from 0-5, with the highest number representing a better score.
Elbow Dynamometry
时间窗: 36-48 months post-surgery
Change from baseline to 36-48 months post-surgery. Elbow dynamometer measures muscle strength using a handheld portable dynamometer
Spinal Cord Independence Measure
时间窗: 36-48 months post-surgery
Change from baseline to 36-48 months post-surgery. SCIM addresses three specific areas of function in patients with SCI, 1) Self-care (feeding, grooming, bathing, and dressing), 2) respiration and sphincter management, and 3) patient's mobility abilities (transfers from bed and indoors/outdoors). SCIM guide clinicians in determining treatment goals/objectives for SCI patients helping therapists assess measurable outcomes in their functional independence. Scores range from 0-100 with a higher score representing better function.
Electrodiagnosis (Nerve Conduction Study and Electromyography
时间窗: 36-48 months post-surgery
Change in baseline to 36-48 Months post-surgery. NCS/EMG evaluate neuromuscular health and inform the integrity of lower motor neurons.
次要结局
- Modified Ashworth Scale (MAS)(36-48 Months post-surgery)
- Canadian Outcomes Performance Measure (COPM)(36-48 Months post-surgery)
- Capabilities of Upper Extremity Questionnaire (CUE-Q)(36-48 Months post-surgery)
- Spinal Cord Injury Quality of LIfe Questionnaire(36-48 Months post-surgery)
- International SCI Pain Basic Dataset (ISCIPBDS)(36-48 Months post-surgery)
