flaccid paralysis
Học thuậtThân thiện
Definition
Noun: A medical condition characterized by weakness, limpness, or loss of muscle tone, resulting from damage to the nerves that connect to and control the muscles. The affected muscles become soft, floppy, and unable to contract normally.
Usage
This term is used specifically in medical and clinical contexts to describe a type of paralysis. * It is often contrasted with spastic paralysis, where muscles are tight and rigid. * It is a symptom, not a disease itself, and indicates a problem with the peripheral nerves or motor neurons.
Examples
- The patient was diagnosed with flaccid paralysis of the lower limbs after the spinal injury.
- Poliomyelitis is a classic viral infection that can cause flaccid paralysis.
- The examination revealed flaccid paralysis in the arm, suggesting possible nerve damage.
Advanced Usage
- Clinical Description: In flaccid paralysis, deep tendon reflexes are usually absent or diminished, and muscle atrophy (wasting) occurs over time due to disuse.
- Temporary vs. Permanent: Flaccid paralysis can be temporary, as in some cases of Bell's palsy, or permanent, depending on the extent of nerve damage.
