Groping syndrome is also known as bed groping syndrome. Groping is most often seen in delirium of serious illness, such as typhoid, typhus, epidemic B encephalitis, severe pneumonia, hepatic coma and other toxemia, alcohol intoxication, and after overdose of sedatives and atropine intoxication. When the patient sees aimless groping movement of the upper limbs, it is often accompanied by mild disorientation, loss of orientation, irritability, babbling, and disorganized talking, which is called groping symptom. Groping syndrome is an unconscious groping movement of the upper limbs, mainly the elbow, wrist and hand joints. What are the symptoms that can help to diagnose the sympathetic vacuity? 1. tremor Tremor is a kind of limb swinging action caused by the alternate contraction of two groups of antagonist muscles. The accompanying symptoms and common causes are as follows: (1) Resting tremor is obvious at rest, mostly in the hands and fingers, in the shape of rubbing pills, and is aggravated by fatigue, emotional stress and anxiety, and is reduced during activity and disappears during sleep, with muscle tonicity, mostly in Parkinson’s disease (tremor palsy). (2) Senile tremor has symptoms similar to tremor palsy, often manifested as head nodding or head shaking. It is not usually accompanied by changes in muscle tone. It is common in elderly patients with arteriosclerosis. (3) Action tremor tremor appears at the end of the movement and becomes more pronounced when the object is near. (4) Wing-flutter-like tremor This tremor is a slight lateral deviation of the fingers, the metacarpophalangeal joint, the wrist joint occurs irregularly 6 to 9 times per second of rapid and tiny, like a bird wing flutter-like flexion and extension movement, if the previous history of chronic hepatitis, cirrhosis, be alert to hepatic encephalopathy early hepatic coma. If you have a history of chronic hepatitis or cirrhosis, you should be alerted to early hepatic coma. 2, chorea-like movement small chorea disease is also known as rheumatic chorea disease. Mostly subacute onset, or in the unconscious onset. Most often seen in adolescents and women, can be triggered by mental stress and overwork. It is manifested as a rapid involuntary, irregular, non-repetitive and purposeless dance-like movements. Such as squeezing eyebrows, open mouth and tongue, grimacing, nodding head and neck, shrugging shoulders and twisting waist, chest and abdomen, rotating arms and turning palms and bending knees and kicking legs, etc.. Mostly caused by rheumatism. 3, hand and foot tachycardia hand and foot tachycardia for the fingers or toes of a slow and continuous stretching and twisting movements, can be repeated, and more regular. ① Cerebral thrombosis mostly has a history of arteriosclerosis, hypertension and diabetes. Consciousness, dizziness, lightheadedness, involuntary twitching on the side of the lesion, mild hemiparesis and sensory impairment on the opposite side are mostly seen in cerebral thrombosis and pontocerebral cap syndrome. (2) History of infection such as cold and diarrhea within one month before the onset of the disease. The prodromal symptoms before the onset of the disease include headache, lethargy, nausea, vomiting, sleep disturbance and decreased mental activity. In case of tardive dyskinesia, fever and impaired consciousness, basal ganglia degeneration caused by encephalitis should be considered. (3) tachycardia, tremor, scant expression, yellow skin, hepatomegaly, abdominal pain, nausea, vomiting, abdominal distention, dyspepsia, anorexia, diarrhea, greenish-brown or golden-brown pigment ring at the junction of cornea and sclera, hepatomegaly should be considered. 4, hand and foot convulsions hand and foot muscles are tense spasms during the onset of hand and foot convulsions, in the upper extremity manifested as wrist flexion, finger extension, metacarpophalangeal joint flexion, thumb inward near the palm and the little finger opposite. In the lower extremities, the ankle and toe joints are flexed. It is seen in hypocalcemia and alkalosis.
