Introduction To Emg/ncs

Front 1

Amyotrophic Lateral Sclerosis

Back 1

Lou Gehrig's disease; progressive degeneration of motor neurons that leads to eventual death.

Front 2

Brachial Plexus

Back 2

An arrangement of nerve fibers (a plexus) running from the spine (vertebrae C%-T1) , through the neck, the axilla (armpit region), and into the arm

Front 3

Carpal Tunnel Syndrome

Back 3

Mononeuropathy: The median nerve is compressed at the wrist, leading to pain, paresthesias (numbness and/or the pins and needles sensation) and muscle weakness primarily in the hand.

Front 4

Charcot-Marie Tooth disease

Back 4

Polyneuropathy: aka Hereditary Motor and Sensory Neuropathy (HSMN), characterized by loss of muscle tissue and touch sensation, predominantly in the feet and legs but also in the hands and arms in the advanced stages of disease

Front 5

Cubital Tunnel Syndrome

Back 5

Mononeuropathy: a channel through which allows the Ulnar nerve (funny bone) to travel over the elbow. Chronic compression of this nerve is known as Cubital Tunnel Syndrome

Front 6

Diabetes Mellitus

Back 6

Polyneuropathies: a metabolic disorder characterized by hyperglycemia or high blood sugar

-leading cause of polyneuropathies

Front 7

Electromyography

Back 7

a graph of ( or a picture of) the electrical activity of a muscle

Front 8

Lumbosacral Plexus

Back 8

an arrangement of nerve fibres (a plexus) running from the spine of the lumbar nerves, sacral nerves, and coccygeal nerves and into the leg

Front 9

Mononeuropathy

Back 9

A disease of a single nerve

Front 10

Motor Neuron Disease

Back 10

a disease where there is dysfunction in the motor neurons that reach from the brain to the spinal cord and from the spinal cord to the muscles throughout the body

Front 11

Muscular Dystrophy

Back 11

a condition that describes more then 30 genetic and hereditary muscles disease. It is characterized by progressive muscle weakness, defects in muscle proteins, and the death of muscle cells and tissue

Front 12

Myasthenia Gravis

Back 12

a neuromuscular disease leading to fluctuating muscle weakness and fatiguability

Front 13

Myopathy

Back 13

a disease of the muscle. the muscle fibers do not function for any one of many reasons, resulting in muscular weakness. Muscular dystrophy is a myopathy

Front 14

Needle Examination

Back 14

One of two portion of an EMG. the Nerve Condution Study is the other portion

Front 15

Nerve Conduction Studies

Back 15

One of two portions of an EMG, and the portion we will focus to the greatest extent

Front 16

Nerve Conduction Velocity

Back 16

Although used synonymously with Nerve Conduction Studies, velocity implies only one of the measurements we use during a NCS

Front 17

Neuromuscular Transmission

Back 17

Having to do with the movement of acetylcholine (Ach) across the nerve-to-muscular connection

Front 18

Peripheral Nervous System

Back 18

consists of the nerves and neurons that reside or extend outside the central nervous system (the brain and spinal cord) to serve the limbs and organs

Front 19

Peroneal Neuropathy

Back 19

Mononeuropathy: affects the legs, pinching of the peroneal (fibular) nerve just below the knee can result in foot drop, where dorsiflexion of the foot is compromised and the foot drags during walking.

Front 20

Plexopathy

Back 20

a disease of the arrangement of nerves fibers ( a plexus) running from the spine

Front 21

Polyneuropathy

Back 21

a disease that affects many nerves, usually classified as acquired or hereditary

Front 22

Radiculopathy

Back 22

A disease that affects the nerves at the spinal roots

Front 23

Spinal Root

Back 23

The portions of the spinal nerves that arise directly from the spinal cord. There is a dorsal (sensory) and central (motor) root at each level
