“…The rationale for the use of wavelet reconstruction is due to its ability to perform a pattern-oriented analysis [35]. In Methods C and D, the selection of the type of mother wavelet Coiflets is performed by resemblance process [36].…”

“…Interest in pose estimation has increased rapidly in the machine learning and neuroscience communities (9)(10)(11)(12)(13)(14)27); however, clinical applications in humans are limited (18,(22)(23)(24)28). The pros and cons of using currently available pose estimation algorithms for measurement of human movement have been discussed at length (29), and we will discuss our own impressions and suggestions below.…”

“…In this study, we used OpenPose (a freely available human pose estimation algorithm (11,15,16) to measure the frequencies of repetitive upper and lower extremity movements using smartphone videos. Previous studies have used OpenPose to study human gait (17)(18)(19)(20)(21) and quantify tremor severity in persons with PD (22). Other pose estimation algorithms have been used to measure the degree of levodopa-induced dyskinesias (23) and finger tapping frequency in PD that correlated well with clinical ratings (24,25).…”

“…They tracked hand localization points (including fingertips and thumb tips) by evaluating network capabilities, and extracted amplitude, distance, and rhythm to quantify finger tapping. Pang et al [23] used discrete wavelet transform (DWT) to extract the (3D) motion features of each finger joint. The severity of each finger joint tremor was quantified by analyzing the frequency of motion changes.…”
