whole body skeletal muscle contraction
Introduction
Introduction The whole body skeletal muscle contraction is also called the whole body skeletal muscle spasm, which means that the muscles suddenly do not arbitrarily collapse, commonly known as cramps, which will make the patients feel severe pain and muscle movements are not coordinated. The patient straightens the muscles of the affected area and usually reduces the degree of paralysis.
Cause
Cause
1, lower limbs are more likely to occur during strenuous exercise or after exercise.
2, tetanus patients may have local or systemic muscle spasms.
3, low blood calcium, low blood magnesium or alkalosis
4, multiple sclerosis patients engaged in exercise or encounters external sound and light and other sensory stimuli, may suddenly unilateral limb pain and strong sputum.
5, the use of Parkinson's syndrome or antipsychotic drugs after encephalitis may occur.

CT examination of bone and joint and soft tissue --
CT examination of bone and joint and soft tissue is a method of examining bone joints and soft tissues by CT.
Bone imaging --
Bone imaging can diagnose bone tumors and bone metastases 3 to 6 months earlier than X-ray examination, but it should be noted that this method is highly sensitive and low specific.
Bone density determination --
As the population ages, osteoporosis has become a common and frequently-occurring disease. Bone density measurement helps to diagnose osteoporosis. Bone mineral density (BMD) is the most effective predictor of fracture risk, and the fracture risk is geometrically related to bone density. Changes in bone mineral density (BMD) can be monitored using a bone densitometer. The orthotopic spine and/or the bilateral femurs are generally used. When the patient's spine has obvious hyperplasia or deformation, bilateral femoral scans are more meaningful.
There are six methods for measuring bone mineral density:
1.QCT bone densitometer detection method;
2. Ultrasonic bone densitometry detection method;
3. Single photon bone densitometry detection method;
4. Two-photon bone densitometry detection method;
5. X-ray bone density meter detection method;
6. Dual energy X-ray bone density meter detection method.
Diagnosis
Differential diagnosis
It needs to be distinguished from the following symptoms:
Whole body skeletal muscle spasm:
Muscles suddenly do not arbitrarily contracture, commonly known as cramps, will make patients feel severe pain, muscle movements are not coordinated. The patient straightens the muscles of the affected area and usually reduces the degree of paralysis.
Shortened bone deformation:
As osteoporosis continues to increase, tenderness may occur locally in the bone, and even under the action of slight external force, fractures of varying degrees may occur. The most common sites of fractures are in the spine (11th, 12th, and 3rd lumbar vertebrae). The femoral neck and the distal radius of the humerus and the spine have a wedge-shaped compression fracture that deforms and shortens the spine. This is the main reason for the elderly to become shorter. the reason. The shortening of the thoracic vertebra can be accompanied by chest discomfort and pulmonary dysfunction, and symptoms such as bloating and constipation.
Hiccup:
Hiccup is a clinical manifestation of diaphragmatic spasm. It can be applied to the unilateral or bilateral diaphragm. Diaphragm tendon is an intermittent contractile movement of the diaphragm involuntary caused by various causes. Sudden closure of the glottis during inspiration produces a short, special sound. Normally healthy people may cause hiccups due to swallowing too quickly, sudden ablation, or sudden increase in intra-abdominal pressure. More can be self-resolved. Some can last for a long time and become intractable. Intractable hiccups in the late stages of certain diseases suggest a poor prognosis.
