Involuntary twitching of thigh muscles

The phenomenon of involuntary twitching of the thigh muscles is most likely fasciculations. The causative factors of this disease are relatively complex and are often accompanied by a family history. Of course, a single symptom cannot determine that it is fasciculations. We need to fully understand the situation of fasciculations and make a comprehensive judgment based on our own situation to determine whether it is caused by fasciculations. Let’s take a closer look below.

Causes of Fasciculations

Fasciculation is actually caused by the contraction of a group of muscle cells, which is medically known as fasciculation. This type of muscle fascicle tremor can have different sizes and amplitudes. Some small tremors can be felt but not seen, while more obvious tremors can be seen with the naked eye. Muscle twitching is usually benign unless it is accompanied by muscle weakness or atrophy. Most benign muscle twitches have no definite cause. They may occur when you are tired or stressed, and drinking tea or coffee may also aggravate them. This type of palpitations is mostly intermittent, but in a few people it may occur frequently due to physical factors. Many people have experienced eyelid twitching. In fact, eyelid twitching is a benign muscle fasciculation.

However, muscle twitching can also be a warning sign of some neuromuscular diseases. If muscle twitching is accompanied by muscle weakness and atrophy, you should see a neurologist as soon as possible. These disorders include lesions of the motor neurons in the spinal cord, peripheral neuropathy, and a few muscle disorders. These diseases can cause problems in the signal transmission between motor nerve cells and muscles. As a result, the unstable nerves will release some redundant signals, which will cause the muscles to jump. The neurologist must examine the area of ​​muscle weakness, assess the degree of muscle atrophy, and perform nerve conduction and electromyography tests to find the cause. Some diseases can also be treated with medications to reduce muscle twitching.

In fact, clinical motor neuron disease is mainly a manifestation of amyotrophic lateral sclerosis, and most other types are manifestations of different degrees of motor system damage at different stages of the disease development. Progressive muscular atrophy and primary lateral sclerosis eventually develop into amyotrophic lateral sclerosis. Patients with motor neuron disease with simple spinal cord damage generally survive for 3-5 years, while patients with medullary damage (simple or combined with spinal cord damage) survive for less than 2.5 years. The disease mostly progresses slowly, and some authors have reported cases of survival of 10-15 years. There are obvious differences in the speed of development of functional impairment in patients with damage in different parts of the body. Patients with medullary damage will develop complete functional impairment early (occurring in about a few months), while those with spinal cord damage will develop slowly, taking up to 4 years. People with juvenile muscular atrophy can live 20 to 40 years.
