Motion characteristics of subclinical tremors in Parkinson’s disease and normal subjects

Abstract: The characteristics of the Parkinson’s disease tremor reported previously are not applicable to the full spectrum of severity. The characteristics of high- and low-amplitude tremors differ in signal regularity and frequency dispersion, a phenomenon that indicates characterisation should be studied separately based on the severity. The subclinical tremor of Parkinson’s disease is close to physiological tremor in terms of amplitude and frequency, and their distinctive features are still undetermined. We aimed to… Show more

“…Nine studies used two sensors of which the majority placed one on the thumb and one the index finger [54, 58, 64, 70, 71, 73, 85, 88, 101], while Martinez-Manzara et al used one sensor on the hand and one on the finger [67], Samotus et al and Rahimi et al put one on the wrist and one on the index finger [95, 111] and Shawen et al put one on the hand and one on the wrist [86]. In the studies where three sensors were used, the most frequent locations for PD and tremor were hand, forearm and upper arm [74, 92, 102, 116], index finger, hand, forearm [105, 110] or index finger, forearm and upper arm [132, 135]. In children with CP, Newman et al attached one sensor on the sternum and two on both upper arms [12] and in HD, Bennasar et al placed one sensor on the sternum and two on the wrists [29].…”

“…Tasks from the ARAT were included in two studies [28, 123]. Finally, following tasks were included once: the monkey box test [29], the box and block test [90], holding a weight with the wrist [96], wrist extension [75], wrist ab/adduction, flexion/extension, elbow flexion/extension and pro/supination [92], and following a bent wire shape with a wand loop [104]. One study included wrist supination/flexion, hand behind back and wrist flexion/pronation [15].…”
