Aim of this study was to develop an anatomical calibration procedure for wearable Magnetic and Inertial Measurement Units to assess Reach-To-Grasp kinematics in the stroke unit. A calliper hosting a MIMU was used to measure the direction of axes identified by pairs of selected Anatomical Landmarks and the inter-ALs distance along these axes. The upper limb was modelled as a two-link open kinematic chain and forward kinematics was used to estimate the position of the end-effector on six subjects wearing three MIMUs on the thorax, upper arm and forearm while performing fifteen RTG cycles.

Abstract

Aim of this study was to develop an anatomical calibration procedure for wearable Magnetic and Inertial Measurement Units to assess Reach-To-Grasp kinematics in the stroke unit. A calliper hosting a MIMU was used to measure the direction of axes identified by pairs of selected Anatomical Landmarks and the inter-ALs distance along these axes. The upper limb was modelled as a two-link open kinematic chain and forward kinematics was used to estimate the position of the end-effector on six subjects wearing three MIMUs on the thorax, upper arm and forearm while performing fifteen RTG cycles. The proposed procedure showed a low bias and good levels of agreement with respect to reference positional data.
