This article is the second in a series of evidence-based systematic reviews. Data reported cover the impact of dysphagia behavioral interventions on swallow physiology in healthy adults. The behavioral treatments investigated were three postural interventions--side lying, chin tuck, and head rotation--and four swallowing maneuvers--effortful swallow, the Mendelsohn maneuver, supraglottic swallow, and super-supraglottic swallow. ⋯ For non disordered populations, the existing evidence demonstrates differential effects of postural changes and maneuvers on swallowing physiology. Some effects reinforced existing recommendations for the applications of the interventions, while others suggested new ways that the treatments may impact swallow function. Avenues for future research are suggested.

Quantitative sensory testing (QST) has been used to assess neurological function in various chronic pain patient populations. In the present study, we investigated the ability of QST to reliably characterize somatosensory dysfunction in subjects with spinal cord injury (SCI) and neuropathic pain by measuring mechanical, vibration, and thermal detection and pain thresholds. Test-retest reliability was determined based on data collected from 10 subjects with SCI and neuropathic pain who underwent QST on two occasions approximately 3 weeks apart. ⋯ To determine the validity of QST in persons with SCI-related neuropathic pain, we evaluated the relationship between somatosensory thresholds and severity of neuropathic pain symptoms with multiple linear regression analysis. Thermal pain threshold was the only QST variable significantly related to the severity of neuropathic pain symptoms. The present study provides preliminary evidence that QST is a reliable and valid adjunct measurement strategy for quantifying the neurological dysfunction associated with neuropathic pain in persons with SCI.

Altered sensations, including pain, are well-documented consequences associated with spinal cord injury (SCI). Although loss of sensory and motor functions at and below the level of injury is commonly thought to affect individuals with SCI most significantly, secondary consequences that include spasticity, bladder and bowel dysfunctions, infertility, and pain rank among the most difficult conditions to deal with following injury. ⋯ Over the past 15 years, a systematic examination related to the pathophysiology, clinical characteristics, and treatment of pain associated with SCI has provided insights into the spinal and supraspinal mechanisms associated with the development of at- and below-level pain. In this review, experimental studies focusing on the spinal and supraspinal mechanisms associated with pain at and below level will be discussed.

Targeted muscle reinnervation (TMR) is a surgical intervention to improve the control of myoelectric prostheses in high-level upper-limb amputation. This article briefly describes the procedure and presents the protocol for postoperative, preprosthetic care. ⋯ This material is based on more than 6 years of experience treating patients with TMR in a research setting. Detailed results of this research are reported elsewhere.
