Calf muscle spasms after walking

Introduction Calf muscle spasm after walking is a common occurrence. Due to excessive walking or running time, the muscles of the lower limbs are overworked. Refers to the sudden and involuntary contraction of muscles, which can cause muscle stiffness and pain. The true mechanism of muscle spasm has not yet been known, and most studies have concluded that muscle cramps are caused by nerves. There are many causes of convulsions, and excessive accumulation of lactic acid in the muscles and damage to muscle fiber strains can cause paralysis. A variety of specific reasons can be combined because the amount of exercise is beyond the range that the muscle can withstand.

Cause

Causes of convulsions: 1. When muscle fatigue occurs after prolonged exercise, it continues to exercise. 2. Poor local circulation. 3. Excessive loss of water and salt. 4. Insufficient levels of minerals (such as magnesium and calcium) in severe diarrhea, vomiting and diet. 5. The ambient temperature suddenly changes. 6. Muscle or tendon laceration. 7. Excessive emotional stress. 8. Engage in exercise or poor muscle coordination in an inappropriate position. 9. The incidence of cramps in some chronic diseases and pregnant women will also increase.

Physical examination: After walking, the calf muscle spasm, local muscles bulge, can not stretch the legs, there will be soreness or severe pain.

Evaluation of muscle spasm:

1. Modified Ashworth classification method: The improved Ashworth classification method is the main method for clinical evaluation of sputum. The manual examination is performed by the examiner based on the resistance felt when the subject's joints are passively moved.

2. Biomechanical assessment methods include pendulum test and equal velocity device evaluation methods.

Differential diagnosis

Differential diagnosis of calf muscle spasm after walking:

1, calf cramps: calf cramps, people in the north usually called "leg belly twist". Because the contraction or relaxation of the leg muscles during exercise can cause the blood vessels to be squeezed and the blood circulation of the legs to be accelerated, the metabolic products can be taken away in time. However, due to various factors, the metabolites may accumulate, and to a certain extent, the muscles will be strongly stimulated to cause contraction, thereby causing cramps in the calves.

2, calf cramps when sleeping: Many people have experienced the calf cramps during nighttime sleep. Calf cramps are actually abnormal muscles and muscles that cause leg muscles or muscle groups. At this time, the tensile strength of the muscle bundle is significantly greater than the tensile strength of the muscle bundle when the muscles are normally contracted. Therefore, there is acidulence or comparison when the calf cramps. Intense painful feeling. In general, seizures can last for a few seconds or tens of seconds.
