Muscle function loss
Alternate Names : Paralysis, Paresis, Loss of movement, Motor dysfunction
Definition
Muscle function loss is when a muscle doesn't work or move normally. The medical term for complete loss of muscle function is paralysis.
Overview & Considerations
Loss of muscle function may be caused by: - Injury such as a broken neck or back
- Nerve damage (neuropathy)
- Not using a muscle
- Stroke or other brain injury
The loss of muscle function after these types of events can be severe, and often will not completely return.
Paralysis can be temporary or permanent. It can affect a small area (localized) or be widespread (generalized). It may affect one side (unilateral) or both sides (bilateral). If the paralysis affects the lower half of the body and both legs it is called paraplegia. It if affects both arms and legs, it is called quadriplegia. If the paralysis affects the muscles that cause breathing, it is quickly life threatening.
