Fig. 3From: Reach-to-grasp kinematics and kinetics with and without visual feedback in early-stage Alzheimer’s diseaseForce analysis for reach-to-grasp kinetic performance. a The force components applied by the thumb and index finger upon the apparatus; b the phases of reach-to-grasp kinetics and the GF and LF curves during grasping, lifting and holding the apparatus. The lifting phases can be further divided into the preload phase (in green) and the load phase (in pink)Back to article page
