Abstract

Tremor is the most common movement disorder. The objective of the current study was to find correlation between disability due to tremor (daily living score) with the functional performance tests like nine-hole peg and box and block. A total of 100 subjects with tremor, categorized in seven diagnostic groups fulfilling the respective diagnostic criteria studied. Clinical assessment using activities of daily living scales (ADL-T24) and tremor severity score done on each patient. The nine-hole peg score (in seconds) and box and block score (number of blocks in 60 seconds) calculated in each. We found that tremor severity was proportionate to ADL-T24 score and had a positive correlation with the disease duration. Overall, there was a moderate positive correlation between ADL-T24 score and 9-HPT score (R2=0.52) whereas a strong negative correlation between ADL-T24 and BBT score (R2=-0.66). An inverse pattern was observed between 9-HPT score and BBT score with a moderate negative correlation (R2=-0.58). It was concluded that the functional performance tests correlate well with the daily living scores. Thus the tremor severity can be quantified on time based measures and are useful for tremor assessment.
