CLONUS Meaning and
Definition
-
Clonus is a medical term that refers to a neurological condition characterized by involuntary, rhythmic muscle contractions or spasms. These contractions occur as a result of an abnormal reflex arc in the nervous system. Clonus specifically involves repetitive, rhythmic muscle movements that alternate between contraction and relaxation.
Clonus most commonly affects the muscles in the ankles and wrists, but it can also occur in other muscle groups. It is typically caused by damage or dysfunction in the upper motor neurons of the central nervous system, specifically the brain and spinal cord. This can be a result of conditions such as multiple sclerosis, stroke, spinal cord injury, or brain injury.
The rhythmic contractions in clonus tend to occur when the affected muscle is stretched or stimulated. For instance, tapping the tendon or performing certain movements may trigger clonic movements. The rhythmic contractions can range from mild to severe, and they may persist for varying durations depending on the underlying cause.
Clonus is often identified and diagnosed through clinical examination, where a healthcare professional may observe the involuntary muscle contractions and assess the individual's reflexes. Treatment of clonus typically involves addressing the underlying cause of the condition, such as managing specific neurological disorders or providing physical therapy to strengthen muscles and improve coordination.
If left untreated, clonus can cause discomfort, affect mobility and coordination, and potentially lead to complications that hinder daily activities. Therefore, it is important for individuals experiencing clonus-like symptoms to consult with a healthcare professional for appropriate evaluation and guidance.
