![]() Kappa statistics showed high inter-rater agreements and high agreements between estimated scores derived from the accelerometer signals and the mean Clinical Tremor Rating Scale evaluated in every session. ![]() The under-rating tendency was then repeated by other uninformed neurologists in Session III. The participating neurologists corrected this tendency in Session II after being informed of it. Neurologists tended to under-rate the less affected hand in resting tremor when the contralateral hand had severe tremor in Session I. The tremor measured by accelerometer was compared with clinical ratings. The videotaped tremor was rated by neurologists using clinical rating scales. ![]() Tremor amplitudes were measured objectively using tri-axis-accelerometers for both hands simultaneously in 53 patients with Parkinson’s disease during resting and postural tremors. This was observed through objective tremor measurement with accelerometers. The objective of this study was to report clinicians’ tendencies to under-rate Parkinsonian tremors in the less affected hand. This is, therefore, a subjective rating that is dependent on clinical expertise. ![]() Abstract The standard assessment method for tremor severity in Parkinson’s disease is visual observation by neurologists using clinical rating scales.
