Many elderly people suffering from Parkinson’s disease, many patients will appear some physical incoordination phenomenon, generally will appear shaking, this is the early symptoms of performance, causing Parkinson’s has many causes, but if you want to have a thorough understanding of this disease, we should first start with the symptoms of the disease performance. 1, special posture: Although the patient’s whole body muscles can be involved, muscle tone is increased, but at rest flexor muscle tone is higher than the extensor muscle, so the patient appears special posture: head forward, trunk slightly flexed, upper arm inward, elbow joint bending, wrist slightly extended, finger metacarpal joint bending and interphalangeal joint straightening, thumb to palm, hip and knee joints mildly bent. 2.Motor retardation: In the early symptoms of Parkinson’s, due to the straightening of the upper arm muscles and finger muscles, the patient’s upper limbs are often unable to make fine movements, such as untying shoelaces, buttoning and other movements become much slower than before, or simply cannot be completed successfully. Writing also gradually becomes difficult, and the handwriting becomes curved and smaller, which is medically known as “microcapitalism”. Facial muscle movements are reduced, the patient rarely blinks, and his or her expression is dull, as if he or she is wearing a mask. When walking, it is difficult to start, once the step is started, the body leans forward, the center of gravity shifts forward, the pace is small and faster, and cannot stop in time, that is, “panic gait”. 3. Resting tremor: Tremor is often an early symptom of Parkinson’s. It usually starts at the distal end of one side of the upper limb, with the thumb, index finger and middle finger as the main focus, and manifests itself as a movement of the fingers as if they were rolling pills or counting banknotes. It then gradually extends to the ipsilateral lower extremity and the contralateral extremity, and in the late stage, it may spread to the jaw, lips, tongue and head. In the early stage of the disease, the patient does not care much about the tremor, which often appears when the fingers or limbs are in a particular position and disappears when the position is changed. Later, it develops only when the limb is at rest. Parkinson’s causes the whole body muscles to be involved, and muscle tone is increased, but flexor muscle tone is higher than extensor muscle tone at rest, so the patient has a special posture: head tilted forward, trunk slightly flexed, upper arm tucked in, elbow bent, wrist slightly extended, metacarpophalangeal joint bent and interphalangeal joint straightened, thumb to palm, hip and knee joints mildly bent. Muscle stiffness Parkinson’s also manifests itself as a loss of flexibility and stiffness in the limbs and torso of the person with the disease usually. Motor retardation Due to the straightening of the upper arm muscles and finger muscles, the patient’s upper limbs are often unable to perform fine movements, such as untying shoelaces and buttoning, which become much slower than before or cannot be completed successfully at all. Parkinson’s is a disease that many middle-aged and elderly people are prone to suffer from, and its appearance makes many patients unable to take care of themselves, which seriously affects their lives.
