Trajectory formation of the center-of-mass of the arm during reaching movements

Minimum Principles in Motor Control

“…For instance, there is now ample evidence that, contrary to the theory's prediction, hand paths of point-to-point movements are not shape-invariant throughout the workspace. In numerous experiments, it has been shown that horizontal-plane point-to-point movements are essentially straight if they are performed near the workspace center and are directed along the anterior posterior axis (Flash 6 Hogan, 1984;Haggard, Hutchinson, 6 Stein, 1995;Miall and Haggard, 1995;Morasso, 1981), but if they start or end near the workspace boundaries, they are noticeably curved (Osu, Uno, Koike, 6 Kawato, 1997;Suzuki, Yamazaki, Mizuno, 6 Matsunami, 1997;Uno et al, 1989). Curved hand paths have also been found by Atkeson and Hollerbach (1985) and Flanagan and Ostry (1990) for vertical as well as for inward-and-upward diagonal movements in the sagittal plane, by Lacquaniti, Soechting, and Terzuolo (1986) for inward-and-upward movements directed toward the subjects' noses, and by Desmurget et al (1995) for outward-and-upward reach-to-grasp movements.…”

Kinematic characterization of functional reach to grasp in normal and in motor disabled children

“…At present, it is well accepted that the reaching movement in healthy adults shows a typical bell-shaped velocity profile with a single acceleration and deceleration phase [4,[9][10][11].…”

Disassembly task evaluation by muscle fatigue estimation in a virtual reality environment

“…Kinect 2 was used to measure this angle and the data are as presented in Table 2. Concerning the parameters of the arm, they are the same as in [45] presented in Table 3. The values of for each component, calculated according to equation (18) are presented in Table 4.…”
