Is shaking hands Parkinson’s disease?

　　Why do my hands shake after lifting heavy objects? Is it Parkinson’s disease? This is normal and will be more noticeable if you lack exercise. But don’t worry too much, as long as it is not continuous or intermittent hand shaking, there is no problem.
　　So which tremors are problematic?
　　Essential tremor, also known as essential tremor, is characterized by postural or action tremors in the distal upper limbs, which may be accompanied by tremors in the lower limbs and head. The tremor frequency is 4-12 Hz. It is a common movement disorder disease .
　　Functional tremor often occurs when there are certain mental factors such as anxiety, tension, and fear. Compared with essential tremor, its frequency is faster (8-12 Hz) but its amplitude is smaller, and it has corresponding psychological characteristics. Symptoms can disappear after the triggering factors, the most common factor is the increase in sympathetic nerve excitability.
　　Parkinson’s disease tremor, also known as “shaking paralysis”, is a common degenerative neurological disease with characteristic motor symptoms, including resting tremor, slow movement, muscle rigidity and postural balance disorder, etc., accompanied by abnormal Motor symptoms. This requires timely detection, timely use of drugs or rehabilitation therapy, etc. to alleviate.
　　Metabolic tremor is mostly postural tremor, and the most common cause is hyperthyroidism, which causes high-frequency and fine-grained postural tremor in the upper extremities, often accompanied by other systemic signs, such as exophthalmos, hyperhidrosis, and weight loss. Other causes include renal failure, hypoglycemic reactions, and liver disease.
　　Drug-induced tremor For patients with short-term tremor, attention should be paid to asking about the medication history. Common drugs that induce tremor include β-receptor agonists, theophylline drugs, antidepressants, thyroxine, and amiodarone. Drugs that block or inhibit dopamine can cause resting tremors and parkinsonism, including antipsychotics (haloperidol, risperidone, etc.), dopamine blockers, and calcium antagonists (cinnarizine and flunarizine) Lizine), etc.
　　Cerebellar tremors are tremors caused by definite cerebellar lesions, mainly intention tremors, and may have postural tremors with a low tremor frequency (3-4 Hz), often accompanied by other signs of cerebellar lesions, such as nystagmus, structural Dysphonia, ataxia, abnormal rotation movements, dysmetria, etc.
　　How is tremor clinically graded?
　　The National Institutes of Health of the United States proposed tremor grading standards:
　　grade 0: no tremor;
　　grade 1: slight, tremor is not easy to detect;
　　grade 2: moderate, tremor amplitude < 2 cm, non-disabling; 　　grade 3: obvious, tremor amplitude of 2 ~ 4 cm, partially disabled; 　　grade 4: severe, tremor amplitude > 4 cm, disabled.
　　From grade 2, tremors have had an impact on our lives. Without intervention, tremors will only get worse and cause more damage to the patient’s body.
　　Therefore, there are many reasons for hand tremors, not necessarily caused by Parkinson’s disease. If necessary, please seek medical treatment in time.
