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.

Causes of paralysis include:
Amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease)
Paralytic shellfish poisoning
Periodic paralysis
Peroneal dystrophy

Home Care
Sudden loss of muscle function is a medical emergency. Seek immediate medical help.
After you have received medical treatment, your doctor may recommend some of the following measures:
Follow your prescribed therapy.
If the nerves to your face or head are damaged, you may have difficulty chewing and swallowing or closing your eyes. In these cases, a soft diet may be recommended. You will also need some form of eye protection, such as a patch over the eye while you are asleep.
Long-term immobility can cause serious complications. Change positions often and take care of your skin. Range-of-motion exercises may help to maintain some muscle tone.
Splints may help prevent muscle contractures, a condition in which a muscle becomes permanently shortened.
