OBJECTIVE APOE epsilon4 has been associated with late-onset familial and sporadic AD and delayed recovery from head injury. The authors examined the relationship between functional recovery of patients with head injury and the APOE alleles. METHODS Thirty-one patients with head injury who had completed the Acute Neurorehabilitation Program at Helen Hayes(More)
CLINICAL CASE This case report documents outpatient cardiac rehabilitation (CR) in a 28-year-old woman born with transposition of the great vessels, tricuspid atresia, hypoplastic right ventricle, and an atrial septal defect. Surgical procedures were performed during childhood to correct these defects. In 2006, she underwent the following procedures: Fontan(More)
Memory dysfunction is a recognized and difficult to treat complication of traumatic brain injury (TBI). Since medial-temporal lobe injury is a frequent contributor to memory dysfunction in TBI, it is likely that an acetylcholine deficit contributes to memory dysfunction in this population. Recently, Donepezil, an acetylcholine-esterase inhibitor which has(More)
PURPOSE Although strategies exist for improving cardiac rehabilitation (CR) participation rates, it is unclear how frequently these strategies are used and what efforts are being made by CR programs to improve participation rates. METHODS We surveyed all CR program directors in the American Association of Cardiovascular and Pulmonary Rehabilitation's(More)
BACKGROUND Assessment of the reliability of performance measure (PM) abstraction is an important step in PM validation. Reliability has not been previously assessed for abstracting PMs for the referral of patients to cardiac rehabilitation (CR) and secondary prevention (SP) programs. To help validate these PMs, we carried out a multicenter assessment of(More)
PURPOSE Prior studies suggest that program capacity restraints may be an important reason for outpatient cardiac rehabilitation (CR) underutilization. We sought to measure current CR capacity and growth potential. METHODS We surveyed all CR program directors listed in the American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR)(More)
Heart-rate variability (HRV), a measure of fluctuation around the mean heart rate, reflects the sympathetic and parasympathetic balance of the autonomic nervous system, and is an excellent technique to study cardiovascular tone in patients with neurological injuries. The purpose of this study was to determine whether abnormal HRV is present in patients with(More)
BACKGROUND AND PURPOSE High-velocity (HV) exercise is defined as performing a concentric muscle contraction as fast as possible, or in 1 second or less. Low-velocity (LV) exercise is defined as using 2 seconds to complete the contraction. A comparison of HV to LV exercise performed by community dwelling older adults indicates that HV exercise produces(More)
STUDY OBJECTIVE To assess blood pressure (BP) response to continuous maximal arm ergometry in patients with spinal cord injury (SCI). DESIGN Cross-sectional analysis of data collected for a prospective study of functional electrical stimulation in patients with SCI. SETTING Short-term rehabilitation hospital. PARTICIPANTS Twenty individuals with SCI;(More)
