A low-cost quantitative continuous measurement of movements in the extremities of healthy men with typical development

Detection of movements in the extremities of people with Parkinson disease was developed to enhance the gold-standard structured assessment of people with Parkinson’s disease assessed by the visual observation by the examiner of the person with Parkinson’s disease (Goetz, et al., 2008). This data represents the administration of a low-cost quantitative continuous measurement of movements in the extremities of people with Parkinson's disease by examiners certified in the Movement Disorders Society-sponsored revision of the Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) (Goetz, et al., 2008) to healthy men with typical development in person. The examiner instructed the participant how to perform each task. The examiner demonstrated the movements. The examiner did not continue to perform the task while the participant was performing the tasks. The examiner instructed the participant to perform each movement as quickly and fully as possible. The examiner encouraged the participant to execute each motion with the maximal speed and range of motion. The examiner sought to capture at least 60 optimal repetitions for each motion. A technologist recorded the output of the instrumentation of each assessment (Harrigan, et al., 2020) and operated a video camera to record the movements of the participants during the testing session. A second (retest) assessment of the protocol was performed after a month for each participant.

Two experts certified in the MDS-UPDRS (Goetz, et al., 2008) then edited the original videotapes to extract only the administration of each task. One expert had participated as examiner and participant in the videotaped segments. The videotape segments correspond to the tasks of the protocol (3.17RTU: 3.17 Rest tremor amplitude upper limbs, 3.17RTUC: 3.17 Rest tremor amplitude upper limbs counting, 3.15PT: 3.15 Postural tremor of the hands, 3.4FT: 3.4 Finger tapping, 3.5HM: 3.5 Hand movements, 3.6PS: 3.6 Pronation-supination movements of the hands, 3.9ACU: 3.9 Arising from chair upper limbs, 3.9ACL: 3.9 Arising from chair upper limbs, 3.17RTL: 3.17 Rest tremor amplitude lower limbs, 3.17RTLC: 3.17 Rest tremor amplitude lower limbs counting, 3.7TT: 3.7 Toe tapping, 3.8LA: 3.8 Leg agility) (McKay, et al., 2019). The participants are identified by their original identification number (Harrigan, et al., 2020). The first (test) session was designated with "F." The second (retest) session was designated with "S."
