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

Dataset of quality assurance measurements of rhythmic movements

“…Although this dataset was obtained to identify deficits in the performance of rhythmic processes by humans, the general framework also constitutes the basis for the quality assurance of rhythmic processes by machinery and technology utilizing a vast spectrum of rhythmic activities. The sequential publications of the procedure dealt with the measurement of movements by humans conducting repetitive tasks [ 1 , 12 , 17 , 21 ]. The goal of the current manuscript is to provide the means to generalize these data for worldwide use to assess the qualities of general rhythmic processes.…”

“…An electronic framework was constructed in Urbana, Illinois, United States, to represent the signals from the accelerometers attached to the extremities of participants in Baltimore, Maryland, United States, and their transforms so that international raters could access the images and submit rating scores to the administrator for future analysis [15] , [16] , [17] . The electronic framework provided the means for 35 trained rates around the world to independently visualize and score the random representation of accelerometer signals and their fast Fourier [5] and amor and bump continuous wavelet [6] transforms.…”

“…The team of international raters completed ratings of the signals and their transforms independently using criteria like the scoring systems for live assessments of movements in human participants [ 1 , 2 ]. The raters scored signals and transforms for deficits in the sustained performance of rhythmic movements (interruptions, slowing, and amplitude decrements) often observed in people with Parkinson's disease [15] , [16] , [17] , [18] , [19] , [20] . Raters were first presented the images of the signals and transforms of a man with multiple system atrophy as a test and a retest in a different random order.…”

“…After the raters completed the assessments of the man with multiple system atrophy, they were presented random test and retest panels of the images of signals and transforms of ten participants with Parkinson's disease who completed a single rating session. After the raters completed the assessments of the participants with Parkinson's disease who completed one set of ratings, they were presented random test and retest panels of the images of signals and transforms of (A) ten participants with Parkinson's disease and (B) eight age- and sex-match healthy participants with typical development who completed two rating session separated by a month or more [15] , [16] , [17] , [18] , [19] , [20] . The data provide a framework for further analysis of the acquired information.…”
