The time domain variables were derived from the sensor signals. Additionally, the frequency domain variables were derived from the power spectrum of the angular velocity signal. Spearman correlation analysis was employed in the relationship between the variables and clinical score.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>The RMS angular velocity of roll and yaw directions at the hand joint were strongly correlated with the clinical rating scale ([Formula: see text] 0.7, [Formula: see text] 0.01). Similarly, the peak power of roll and yaw directions at the hand joint were moderately correlated with the clinical rating scale ([Formula: see text] 0.61 and [Formula: see text] 0.67, [Formula: see text] 0.01). In contrast, no significant correlation coefficients were observed in the peak frequency ([Formula: see text] 0.05).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION:<\/jats:title>\n                    <jats:p>These results indicate that hand tremor of roll and yaw directions are more associated with assessment of severity of ET compared to other joints.
