Lower extremity rigidity in Parkinson’s disease is often accompanied by paroxysmal spasms, and walking may be accompanied by toe spasms with pain. Patients with low back pain often have a flexed back-like standing posture, which is relieved when standing up straight or lying down; sitting back anteversion is often more pronounced, accompanied by increased pain, reflecting body posture and muscle rigidity as the main cause of pain, which can also manifest as neck and shoulder pain, headache, and arm aches. However, later in the course of medication, a few patients may develop spastic pain in the lower extremities, especially the toes. For tremor-type Parkinson’s disease, if an elderly person develops tremors in the hands and feet, it often draws the attention of the family and they are brought to the doctor. The disease can be treated actively and effectively in a timely manner. In contrast, for patients with rigid Parkinson’s, the disease is often delayed. This is mainly because the stiffness of the limbs cannot be seen by outsiders and is often overlooked. Generally speaking, in the early stage of the disease, patients will feel inflexible limb movement, not to move, and sore neck and shoulder muscles. It is often considered a manifestation of aging, and some patients even go to orthopedic clinics because of stiff and sore neck muscles, which are not improved for a long time. Long-term stiffness in patients with Parkinson’s disease may lead to the following problems: 1. The limbs and trunk lose their flexibility and become stiff. 2. Early on, it mostly starts from one limb. Initially, you feel inflexibility and stiffness in the movement of one limb, and it gradually worsens, and you have difficulty with motor slowing and even doing some of the movements of daily life. 3. Soreness in the neck, shoulder, arm or leg. 4.Limb contracture and deformity Limb contracture, deformity and joint stiffness are mainly seen in the late stage of the disease, so early and middle stage patients should be encouraged to exercise more, and more passive activities should be done for late stage patients. 5, leading to the occurrence of digestive system complications, manifested as: nutritional disorders and water-electrolyte disorders, related to swallowing difficulties, reduced diet, inadequate fluid supplementation, swallowing difficulties because of the coordinated action of the pharyngeal muscles is impaired, eating too quickly can lead to choking and choking, small intestine motor malfunction, constipation, its high incidence (50% to 67%) and persistence to bring pain to patients, digestive system Various complications have the same pathophysiological basis and are due to excessive tension of gastrointestinal smooth muscle, slow movement and poor coordination with each other.
