An OpenSim-based closed-loop biomechanical wrist model for pathological tremor simulation (dataset)

This study uses a dataset from 5 subjects, including 4 with Parkinson's Disease (PD) and 1 with Essential Tremor (ET). The data includes Inertial Measurement Unit (IMU) and surface electromyography (sEMG) signals. The dataset supports conclusions in the article "An OpenSim-based closed-loop biomechanical wrist model for pathological tremor simulation."

During the study, two electrodes were placed on the ECRL and FCU muscles of the most affected arm for sEMG recordings. An IMU was placed at the back of the hand to record angular velocity signals for IMU data. Volunteers were asked to keep their hands steady and extend both arms forward. The sEMG and IMU signals were recorded for one minute each at sample frequencies of 1925.93 Hz and 148.5 Hz, respectively.

Regarding the naming convention, each file follows the format "patientnumber_age_sex_disease_arm_timesincediagnose.mat." Additionally, the time vectors for sEMG and IMU are represented as Xs, Xs1, ... Xs17.
