Decerebrate rigidity is characterized by abnormal posturing and increased muscle tone due to disruptions in the brain's control over motor pathways. Cutting the dorsal roots interrupts sensory feedback to the central nervous system, which can help reduce excessive excitatory input to spinal motor neurons. This disruption alleviates the hyperactive reflexes and muscle tone associated with decerebrate rigidity, leading to a reduction or disappearance of the condition. Essentially, the loss of sensory input helps restore a more balanced state of motor control.

What is Dorsal rhizotomy?
Dorsal rhizotomy is a surgical procedure that involves cutting some of the sensory nerve fibers in the spinal cord's dorsal roots. This procedure is often used to treat severe cases of spasticity or muscle stiffness in conditions like cerebral palsy. By disrupting the nerve signals responsible for the abnormal muscle contractions, dorsal rhizotomy can help improve motor function and alleviate symptoms.
