What's going on with gear like rigidity?

summary

Gear like rigidity, myotonia is due to the extrapyramidal system of increased muscle tension, the driving muscle and antagonistic muscle tension has increased. When the joint is in passive motion, the increased muscle tension is always consistent, and the patient feels uniform resistance. If the patient is complicated with tremor, he can feel intermittent pause on uniform resistance when stretching and flexing the limb. If the gear is rotating, it is called "gear like rigidity".

What's going on with gear like rigidity?

The limbs and body of patients with Parkinson's disease usually lose flexibility and become stiff. If you pick up the patient's arm or leg and help him move his joints, you will obviously feel that his limbs are stiff and it is very difficult to move his joints, like folding a lead pipe back and forth. If the affected limb trembles at the same time, there will be intermittent pause feeling, just like the feeling when two occluding gears rotate, that is, the gear like rigidity.

The onset of acute dystonia is acute and appears soon after medication. It is more common in young people and is characterized by strange muscle spasm. It is mainly involved in the neck and head muscles. The most common is the involuntary spasm of the tongue and oral muscles, resulting in tense contraction of the masticatory muscles, difficulty in opening the mouth, difficulty in speaking and swallowing, facial mischief, or spasmodic torticollis. This reaction is related to the sensitivity of the individual. It is effective to use anti tremor paralysis drugs, anti histamine drugs or barbiturates.

The onset of tardive dyskinesia is slow. It occurs several weeks, months or years after the administration of nerve tranquilizer, or even after the withdrawal of the drug. It is characterized by rigid and repetitive involuntary movements of lips and tongue, sometimes accompanied by dancing like movements of limbs or trunk, and body axial movements. The use of anti tremor paralytic drugs is not only ineffective, but sometimes aggravates the symptoms. There may also be hypotonia - paralysis, involving the neck muscle, waist muscle, etc., such as the waist can not be straight up, convex abdomen, neck soft, can not raise the head, walking without walking, can not lift the leg, the heel to mop the floor.

matters needing attention

Gear like ankylosis is caused by the increase of extrapyramidal muscle tension, the increase of the muscle tension of the activator and antagonistic muscles. In the prevention and treatment, it is mainly to prevent the occurrence of extrapyramidal diseases and reduce the muscle tension. When extravertebral system disease or other diseases causing muscle tone increase occur, we should actively treat the primary disease, pay attention to maintain the normal supplement of nutrients in the body, maintain the balance of electrolytes and other symptomatic treatment.
