ReviewNerve and Tendon Transfer Surgery in Cervical Spinal Cord Injury: Individualized Choices to Optimize Function.
Background: Recent adaption of nerve transfer surgery to improve upper extremity function in cervical spinal cord injury (SCI) is an exciting development. Tendon transfer procedures are well established, reliable, and can significantly improve function. Despite this, few eligible surgical candidates in the United States undergo these restorative surgeries. ⋯ Early results indicate variable return of meaningful function with less immobilization but longer periods (up to years) required to gain appreciable function. Conclusion: Nerve and tendon transfer surgery sacrifice an expendable donor to restore a missing and more critical function. These procedures are well described in hand surgery; are reliable, well tolerated, and covered by insurance; and should be part of the SCI rehabilitation discussion.

Assessing Heart Rate Variability As a Surrogate Measure of Cardiac Autonomic Function in Chronic Traumatic Spinal Cord Injury.
Background: Although cardiac autonomic dysfunction is a contributing factor for cardiovascular disease development in individuals with a spinal cord injury (SCI), it remains poorly understood. Heart rate variability (HRV) analysis has the potential to non-invasively assess the cardiac autonomic nervous system. The study objectives are (a) to determine if there are differences in HRV measures across neurological level of impairment (NLI) and American Spinal Cord Injury Association Impairment Scale (AIS) subgroups, and (b) to determine if there is a relationship between HRV frequency measures (low frequency [LF] and high frequency [HF]) at rest. ⋯ The results were considered inconclusive, since possible explanations include inadequate sample size as well as other physiological considerations. A positive correlation was found between LF and HF when assessed at rest. The relationship between LF and HF may not necessarily represent a rebalanced autonomic nervous system, but it does question the utility of solely measuring LF:HF at rest in persons with chronic SCI.
