Movement Disorder (MD) are neurological conditions that cause problems with movement. This can include increased voluntary/involuntary movement, or decreased or slow voluntary movement. There are a wide range of causes of MD, from genetics, infections, to brain damage.
Some common examples of MD are:
- Chorea and Huntington’s Disease
- Parkinson’s Disease
- Tardive Dyskinesia
- Tourette Syndrome
Some symptoms of movement disorder are:
- Muscle weakness
- Tingling or numbness in arms, legs, hands, feet, and/or face
- Muscle cramps, spasms, and/or twitching
- Muscle paralysis
An electromyography (EMG) test—which measures the electrical activity of muscles and nerves—is used to diagnose MD. Since nerves send out electric signals to make your muscles react in certain ways, the test studies the signals they give off to identify if your nerves and muscles are responding correctly. If your nerves and muscles aren’t responding properly, it helps your healthcare provider diagnose if you have MD.
Treatments will vary depending on which MD you have. Your healthcare provider will guide you on the best course of action once your diagnosis is confirmed.
