Comparative Effectiveness Review of Functional Electrical Stimulation (FES) for Upper Extremity Rehabilitation Post Stroke

May 9, 2019 Medical Technology Directory

Health Problem: In the United States, stroke afflicts 795,000 individuals each year, with 610,000 being a first stroke and 185,000 being recurrent stroke. Stroke causes 140,000 deaths annually. It is estimated that 29% to 75% of stroke survivors experience upper extremity impairments and stroke reduces mobility in more than 50% of survivors age 65 years and older. Technology Description: Functional electrical stimulation (FES) devices apply short-duration electrical impulses to peripheral nerves that control paretic (or weakened) muscles to induce muscle contractions of sufficient strength and coordination to allow function or accomplishment of functional tasks. FES is used as an adjunct to...

Comparative Effectiveness Review of Laser Therapy for Psoriasis

April 25, 2019 Medical Technology Directory

Health Problem: Psoriasis is an immune-mediated disease of the skin that affects 7.5 million people in the United States and is characterized by the appearance of red, thickened, scaly patches on the skin. Technology Description: Laser therapy typically involves passing a focused laser beam back and forth over the entire area of a psoriasis lesion. In some protocols, cool air is applied during laser exposure to prevent excess buildup of heat. Single or multiple treatments may be given at a fixed dose or escalating doses and a full course of therapy can take several months. The duration of treatment is often...

Acoustic Radiation Force Impulse (ARFI) Elastography for Detecting Hepatic Fibrosis in Patients with Hepatitis C

April 25, 2019 Medical Technology Directory

Health Problem: Approximately 3.2 million people in the United States have a chronic hepatitis C virus (HCV) infection, which puts them at risk for developing hepatic fibrosis or cirrhosis, a need for liver transplantation, and possible death due to liver failure or liver cancer. However, HCV infection is a treatable disease and effective antiviral treatments that can lead to undetectable levels of the virus are available. An accurate test to detect the early stages of an HCV infection-related complication, such as hepatic fibrosis, may lead to earlier treatment. Technology Description: Acoustic radiation force impulse (ARFI) elastography, also referred to as shear...

Percutaneous Tibial Nerve Stimulation for the Treatment of Symptomatic Neurogenic Lower Urinary Tract Dysfunction

April 15, 2019 Medical Technology Directory

Health Problem: Also known as neurogenic bladder, neurogenic lower urinary tract dysfunction (nLUTD) is a condition in which an individual lacks bladder control due to a brain, spinal cord, or peripheral nervous system disease or injury. Disturbances of storage may result in lower urinary tract symptoms such as urinary urgency, urge urinary incontinence, urinary frequency, and nocturia—the components of overactive bladder syndrome. In patients with focal brain lesions, lesion location may correspond with LUTD. In patients with multiple sclerosis, Parkinson disease, and polyneuropathies, these dysfunctions progress as the disease progresses. The prevalence of nLUTD varies among patients with different neurological...

Comparative Effectiveness Review of Lumbar Total Disc Replacement for Degenerative Disc Disease

April 1, 2019 Medical Technology Directory

Health Problem: It is estimated that 60% to 80% of the adult population in the United States will experience clinically significant low back pain (LBP) at some point in time. The vast majority of LBP is mechanical in nature, i.e., arising from anatomic structures of the spine. Nonspecific chronic LBP may be attributed to normal degenerative changes in the intervertebral discs that are evident by the second or third decade of life. The prevalence of lumbar disc degeneration (DDD) in asymptomatic individuals is 37% in 20-year-olds and increases to 96% in 80-year-olds. The goals of treating patients with symptomatic lumbar...
