Conventional neck traction is provided manually by experienced physical therapists who maintain a desired orientation of the head-neck relative to the trunk while applying the traction. It is postulated that innovative designs of neck exoskeletons can provide the same function both flexibly and accurately. This article presents a novel architecture of a parallel mechanism whose base sits on the human shoulders with 4 parallel chains, each chain having a revolute-revolute-universal-revolute (<jats:italic>RRUR<\/jats:italic>) structure, while the end-effector is connected rigidly to the human head. Each chain has five degrees-of-freedom (DOF) and applies a constraint on the motion of the end-effector. As a result, this parallel mechanism allows two DOFs to the end-effector. These are (i) forward flexion or lateral bending of the head and (ii) vertical translation. An important motivation for the current design with <jats:italic>RRUR<\/jats:italic> structure is to characterize the range of forward flexion\/lateral bending of the head-neck with this structure and the vertical translation to the end-effector. A physical prototype was constructed and tested to evaluate the performance of this mechanism in hardware for the proposed application.<\/jats:p>","DOI":"10.1017\/s0263574724000882","type":"journal-article","created":{"date-parts":[[2024,9,18]],"date-time":"2024-09-18T06:32:40Z","timestamp":1726641160000},"page":"4136-4149","source":"Crossref","is-referenced-by-count":3,"title":["Design
