This article reviews methods that have been developed as part of a clinical initiative on improving outcome measures for motor function assessment in subjects with spinal cord injury (SCI). Physiological motor outcome measures originally developed for limbs-transcranial magnetic stimulation (TMS) of the motor cortex to elicit motor-evoked potentials (MEPs) and mechanical stimulation to elicit spinal reflexes-have been extended to muscles of the trunk. ⋯ Spinal reflex testing of paravertebral muscles is also described. The principal markers for the thoracic SCI motor level that have emerged from this clinical initiative are (1) the threshold of MEPs in paravertebral muscles in response to TMS of the motor cortex, (2) the facilitation pattern and latency of MEPs in intercostal muscles during voluntary expiratory effort, and (3) the absence of long-latency reflex responses and the exaggeration of short-latency reflex responses in paravertebral muscles.

The assessment and treatment of pain in persons with cognitive impairments pose unique challenges. Disorders affecting cognition include neurodegenerative, vascular, toxic, anoxic, and infectious processes. ⋯ This article provides an overview of the assessment, treatment, and management of pain in adults with cognitive impairments. We review types of cognitive impairment; recent work specific to best practices for pain management in patients with dementia, including assessment-tool development and pharmacological treatment; challenges in patients with delirium and in medical intensive care and palliative care settings; and directions for future research.

This article reviews current issues and practices in the assessment and clinical management of sports-related concussion. An estimated 300,000 sports-related concussions occur annually in the United States. ⋯ Current military guidelines for assessing and managing concussion in war zones incorporate information and methods developed through sports-concussion research. We discuss the incidence, definition, and diagnosis of concussion; concussion grading scales; sideline evaluation tools; neuropsychological assessment; return-to-action criteria; and complications of concussion.
