Movement disorders are neurological conditions that affect the speed, fluency, quality, and ease of movement. Abnormal fluency or speed of movement (called dyskinesia) may involve excessive or involuntary movement (hyperkinesia) or slowed or absent voluntary movement (hypokinesia). Electromyography (EMG) is a diagnostic procedure to assess the health of muscles and the nerve cells that control them (motor neurons).
Based on a questionnaire for estimation of disorder, and used a two-step investigation procedure, first by a parent questionnaire with 1,218 responses and second by a confirmatory telephone interview for 197 positive responses.The average estimated values were 11.3% for boys and 5.2% for girls. The prevalences were–blinking: 4.2%, head-jerking: 1.6%, shrugging: 1.2%, mouth-twitching: 0.6%, face-distortion: 0.5%, mouth-opening:
Caffeine and stress should be avoided, and good sleep is recommended.the first medication choices are beta blockers such as propranolol or alternately, nadolol and timolol. Atenolol and pindolol are not effective for tremor. The anti-epileptic primidone is also effective for movement disorders.Second-line medications are the anti-epileptics topiramate, gabapentin and levetiracetam, or benzodiazepines like alprazolam.
