帕金森患者会不会感觉关节僵硬以及肌肉发紧？

Yes, joint stiffness and muscle tightness are common symptoms for Parkinson's disease patients. Here are the details:

• Rigidity or stiffness of the limbs and trunk is one of the main motor symptoms of Parkinson's disease. It is caused by high levels of muscle tone due to problems with the basal ganglia in the brain.

• The rigidity typically progresses slowly over time and initially affects one side of the body, often beginning with an arm or leg. As the disease advances, both sides of the body typically become rigid.

• The rigidity makes it difficult for Parkinson's patients to make voluntary movements as their muscles resist movement. Their limbs may feel heavy and lead to reduced swinging of the arms when walking.

• In addition to rigidity, Parkinson's patients often experience muscle tightness where their muscles are in a constant state of mild contraction. This can cause aching, tension and discomfort in the muscles.

• The muscle tightness affects both superficial muscles like those involved in facial expression as well as deep muscles such as those around the spine and in the abdomen.

• Treatments like medications, physical therapy and deep brain stimulation can help reduce stiffness and muscle tightness in Parkinson's patients but cannot stop their progression over time. The symptoms typically worsen as the disease advances.
