What is the Difference Between Flaccid and Spastic Paralysis?

Flaccid and spastic paralysis are two distinct types of paralysis that result from damage to the nervous system. The main difference between them lies in the muscle tone and contraction:

• Flaccid Paralysis: In this type of paralysis, the muscles become weak, floppy, and cannot contract. It is caused by damage to the peripheral nerves, which are responsible for transmitting signals between the central nervous system and the rest of the body. Flaccid paralysis is characterized by decreased muscle tone and reduced reflexes.
• Spastic Paralysis: In this type of paralysis, the muscles remain in constant contraction, becoming rigid and immobile. It is caused by damage to the central nervous system, which includes the brain and spinal cord. Spastic paralysis is characterized by increased muscle tone and increased reflexes.

While both flaccid and spastic paralysis result in muscle weakness and loss of movement, their manifestations are quite different. Proper diagnosis and understanding of the differences between these two types of paralysis are crucial for developing appropriate treatment plans.

Comparative Table: Flaccid vs Spastic Paralysis

The main difference between flaccid and spastic paralysis lies in the muscle tone and the underlying cause. Here is a table summarizing the differences between the two:

Flaccid paralysis is caused by damage to the peripheral nerves, which control movement, and leads to weakened muscles and decreased reflexes. On the other hand, spastic paralysis is caused by damage to the central nervous system and results in stiff muscles and increased reflexes. Both types of paralysis can cause muscle weakness and loss of movement, but the key difference is the muscle tone and the specific cause of the paralysis.
