“…This paper builds upon the authors' previous work, where learned prototypical motions were first developed [16] and tested in a pilot [25], by looking to demonstrate trajectory control as a feasible control method to position and orient the end-effector of various prosthetic devices. A summary of the method that was used to obtain prorotypical motions is included in section II.…”

“…A; a full description can be found in [16]. The pilot study [25] indicated that trajectory control was superior to both sequential and simultaneous control on a number of criteria, however, the protocol primarily examined the execution of individual submovements rather than whole tasks, grasping was not required, and testing was limited to a 3 DOF device. In the present work we 1) expand the analysis to a more comprehensive task protocol where tasks are comprised of multiple submovements, 2) analyze 4 DOF and 7 DOF devices, and 3) address the following questions regarding trajectory control use in prosthetic devices: i) does it reduce the time it takes to position and orient the hand, ii) does it help mitigate body compensation, and iii) are there differences in user preference between control methods.…”

“…These two metrics provide different perspectives, by looking at both the maximum effects of an individual joint and the aggregate effect of multiple joints acting in unison over time. While ROM has been established and utilized by different groups as a practical quantifier of compensation [11], [16], complementing this metric with trajectory lengths provides motion information not captured using ROM alone [12], [13].…”

“…1a, that enables the study of tenodesis grasp in normative subjects, or individuals without SCI. Adaptor devices have been utilized in transradial prostheses [11], [13], [14], but the TGE is the first developed for tenodesis grasping. In order to study compensatory behaviors in response to TGE, we vary types and orientations of objects as well as location to produce a range of reach-to-grasp movements in 6 subjects, described in Section III.…”
