9, 10 Firstly, bivariate correlation analyses (ie, point biserial correlations between binary and continuous variables) were performed between the dependent measure and each predictor variable. Regression analyses consisted of two steps. The primary dependent measures used for the two regression analyses were (1) the total TRS score at the first clinic visit and (2) change in the TRS total score between the first clinic visit and the last follow‐up examination (ie, follow TRS−baseline TRS). A difference of ⩾1 points between the total right‐sided and left‐sided items was considered positive for asymmetrical disease. Patients were classified as having asymmetrical disease or not using four items on the TRS, two items for the right upper and lower extremity tremor ratings and two corresponding items for the left side. The Tremor Rating Scale (TRS) 8 is a commonly used rating scale of tremor and activities of daily living. The assessment battery included physician ratings of clinical signs, and independent living and occupational capacity, and also a record of drug use, side effects, tremor responsiveness to ETOH, initial most prominent symptom, location of the initial most prominent symptom, and current most prominent symptom and its location. The baseline and last follow‐up characteristics were examined in the current study. 7 In short, patients were assessed at each clinic visit. The data collection procedures have been described in detail previously. One patients was excluded due to placement of a deep brain stimulator, leaving a total of 45 patients. A total of 46 (36%) patients had at least one follow‐up exam (M = 3.6 years, range = 0.3–10 years). A diagnosis of essential tremor is made if patients have postural or kinetic tremor of the head, arms or legs that is not attributable to drugs, caffeine or neurological illness.Īs part of routine clinical care, all patients are offered follow‐up evaluations for management of essential tremor. A clinical series of 128 consecutive patients diagnosed with essential tremor by one physician (RJU) at the Mayo Clinic, Jacksonville, Florida, USA, between July 1994 and March 2000 were selected if it was at least ⩾5 years since their initial clinic visit as of March 2005.
