In this regard, what can cause muscle rigidity?

Muscle rigidity is often triggered by stress. Stress can adversely affect your body's nervous system — including your nerves — and how they function. Your nervous system may respond to stress by putting additional pressure on the blood vessels, which results in reduced blood flow to the muscles.

Beside above, is stiffness a sign of Parkinson's? Rigidity (Stiffness) Stiffness can occur on one or both sides of the body and contribute to a decreased range of motion. Rigidity is one of three telltale symptoms that help doctors make a Parkinson's diagnosis. The other two are slowness of movement (bradykinesia) and tremor.

Keeping this in consideration, how is Parkinson's rigidity treated?

Initial therapy is usually levodopa (administered with carbidopa), dopamine agonists, and/or monoamine oxidase-B (MAO-B) inhibitors. The combination of levodopa and carbidopa is the most effective treatment available for the management of motor symptoms of PD, including rigidity.

Does Parkinson's cause muscle wasting?

Causes of fatigue in Parkinson's disease Many of the symptoms of PD, including slow movement, muscle stiffness, depression, and changes to sleep quality can cause or worsen the symptom of fatigue. In addition, some people with PD experience muscle atrophy, in which the muscles shrink and weaken due to lack of use.
