Tremor of the feet is one of the features of Parkinson’s disease. Parkinson’s disease, also known as idiopathic Parkinson’s disease (PD), or Parkinson’s disease, also known as paralysis agitans (shaking palsy), is a common neurodegenerative disease of the middle-aged and elderly, and is the most common extrapyramidal disease of the middle-aged and elderly. The prevalence is 1000 per 100,000 people over 65 years of age and increases with age, slightly more in men than in women. The main clinical features of the disease: resting tremor, slowed and reduced movements, increased muscle tone, and postural instability are the main characteristics. The diagnosis of foot tremor due to Parkinson’s disease: 1. Clinical manifestations: The onset of the disease is more insidious, with a slow development and gradual aggravation. The main manifestations are: tremor, muscle tonicity, motor retardation, postural gait abnormalities, mouth, pharynx and palate muscle movement disorders, which is a very important point in the diagnosis of Parkinson’s. 2. Exclude Parkinson’s syndrome caused by encephalitis, cerebrovascular disease, poisoning, trauma, etc., and differentiate it from hysterical, catatonic and senile tremor: The diagnosis of Parkinson’s is made mainly based on typical symptoms, and sometimes the differentiation is difficult with the help of auxiliary diagnosis. 3, auxiliary diagnosis: for the diagnosis of Parkinson’s using high performance liquid chromatography can be detected in the cerebrospinal fluid and urine HVA (high vanillic acid) content reduction. Cranial CT may show widening of the cerebral sulcus and enlargement of the ventricles.
