People with Parkinson’s disease can’t straighten their backs because Parkinson’s disease causes the limbs and trunk to have increased muscle tone and the muscles to become stiff, which ultimately results in the body being in a flexed position and the back not being able to straighten. Treatment is based on the use of anti-Parkinson’s disease medications. Parkinson’s disease is a degenerative disease of the nervous system, with symptoms such as resting tremor, slow movement, increased muscle tone, and abnormal posture and gait, etc. Increased muscle tone in the neck, trunk, and limbs can cause muscle stiffness, which ultimately leads to flexion of the body, and the waist can not be straightened up. The treatment of Parkinson’s disease, which causes the inability to straighten the back, is based on oral anti-Parkinson’s disease medications, such as dobutamine. The adverse reactions of this drug are gastrointestinal discomfort, mental abnormalities, etc. It is prohibited for those who are allergic to this drug, should avoid combining with monoamine oxidase inhibitors, and is recommended to be taken 1 hour before or 1.5 hours after meals. It is recommended that patients with discomfort should seek medical attention in a timely manner and use the drug under the guidance of a physician for standardized treatment.
