spasticitási

Spasticity is a motor disorder characterized by a velocity-dependent increase in tonic stretch reflexes and exaggerated tendon jerks. It is one of the most common symptoms of upper motor neuron syndrome, which can result from conditions such as stroke, cerebral palsy, multiple sclerosis, and spinal cord injury.

The increased muscle tone in spasticity can lead to stiffness, involuntary muscle spasms, and difficulty with movement. These spasms can be painful and may interfere with daily activities like walking, eating, and dressing. The severity of spasticity varies greatly among individuals, ranging from mild stiffness to severe, uncontrollable muscle contractions.

Diagnosis of spasticity typically involves a neurological examination to assess muscle tone, reflexes, and range of motion. Imaging techniques like MRI may be used to identify the underlying cause.

Treatment aims to reduce muscle stiffness and spasms, improve function, and manage pain. Strategies include physical therapy, occupational therapy, medication (such as muscle relaxants and botulinum toxin injections), and sometimes surgical interventions like selective dorsal rhizotomy. The specific treatment plan is tailored to the individual's needs and the underlying condition.
