Dataset of quantitative structured office measurements of movements in the extremities

Classification of extremity movements by visual observation of signals and their transforms

“…Thus, we developed a low-cost quantitative continuous measurement of movements in the extremities of people with Parkinson's disease [5] to provide the means to express the dysfunction of movements commonly seen in people with PD in the form of the signals of accelerometers capturing the three-dimensional position in space of the extremities during movements. Our low-cost quantitative continuous measurement of movements in the extremities of people with Parkinson's disease provides the means to assess the dysfunction of participants by ratings of the movements using visual observation of the live behaviors (in person and video) and the output of the instrumentation [5] , [6] , [7] . The goal of the current protocol is to provide the means for trained raters to remotely provide objective assessments of the signals and their transforms of the output of our low-cost quantitative continuous measurement of movements in the extremities of people with Parkinson's disease without observing the participant performance of the tasks [5] , [6] , [7] .…”

To attain this end, we sought to develop a method for 35 experts certified in the MDS-UPDRS [4] to blindly rate the signals and transforms of our quantitative continuous measurement of movements in the extremities of cohorts of people with PD and control and comparison groups [5] , [6] , [7] , [8] , [9] , [10] , [11] .…”

“…The original output from the instrumentation was stored on the laptop used for the study. The original hand-written scores of the full live in-person person ratings as well as the signals and their fast Fourier transforms (FFTs) and continuous wavelet transforms (CWTs) have been published [6 , 7] . The videos of the live assessments are being prepared for publication.…”

“…The videos of the live assessments are being prepared for publication. However, the published materials express data in varying formats that cannot be correlated for blind ratings by experts without access to the original data because the published data are in separate datasets [6] , [7] , [8] , [9] that cannot easily be combined by humans using visual observation. For this reason, we sought to develop a protocol to express the signals and the transforms of the five repetitive movements (3.4 Finger tapping, 3.5 Hand movements, 3.6 Pronation-supination movements of hands, 3.7 Toe tapping, and 3.8 Leg agility) [4 , 5] of each of the cohorts in a format suitable for blind rating by experts unfamiliar with the original data [11] , [12] , [13] .…”

“…Due to the worldwide health crisis meetings of raters in person were forbidden during the conduct of the investigation. Therefore, experts from all around the world were invited to take part in the investigation as trained raters of the signals and their transforms already generated by the cohorts in the original study[ [5] , [6] ]. To verify that each rater was qualified to participate as a rater, each potential rater was required to join the International Parkinson and Movement Disorder Society to obtain certification in the MDS-UPDRS [4] .…”
