Upper motor neuron hyperreflexia refers to a condition where there is an exaggerated reflex response in muscles due to dysfunction of the upper motor neurons in the central nervous system. This can lead to increased muscle tone, stiffness, and involuntary muscle contractions.

Types:

There are different types of upper motor neuron hyperreflexia, including spasticity, clonus, and exaggerated reflexes.

  1. Spasticity: This involves increased muscle tone and stiffness, making movement difficult.
  2. Clonus: Clonus is characterized by rhythmic, involuntary muscle contractions that occur in response to rapid stretching of a muscle.
  3. Exaggerated reflexes: This refers to heightened reflex responses when a tendon is tapped with a reflex hammer.

Causes:

There are various factors that can cause upper motor neuron hyperreflexia, including:

  1. Stroke
  2. Traumatic brain injury
