Muscle rigidity

Muscle Rigidity

Muscle rigidity (pronunciation: /ˈmʌs(ə)l rɪˈdʒɪdɪti/) is a condition characterized by an increased tone of the body's muscles that causes them to resist normal movement.

Etymology

The term "muscle rigidity" is derived from the Latin words "musculus" meaning "little mouse" and "rigidus" meaning "stiff".

Definition

Muscle rigidity is a state of stiffness and inflexibility in the muscles, which can limit movement and cause discomfort. It is often associated with conditions such as Parkinson's disease, dystonia, and neuroleptic malignant syndrome.

Symptoms

Symptoms of muscle rigidity can include stiffness, difficulty moving, pain, and in severe cases, complete loss of the ability to move the affected muscle.

Causes

Muscle rigidity can be caused by a variety of conditions, including neurological disorders such as Parkinson's disease, dystonia, and neuroleptic malignant syndrome. It can also be caused by certain medications, particularly those used to treat mental health conditions.

Treatment

Treatment for muscle rigidity typically involves addressing the underlying cause. This may include medication to manage symptoms, physical therapy to improve mobility, and in some cases, surgery.
