A therapeutic traction device for increasing intervertebral spaces along a cervical spine of a user includes a user interface, a controller, a neck rest section, a crossbar provided with first and second clamps, a curvilinear back pad connected to an anterior side of the crossbar, and a utility box connected to a posterior side of the crossbar. The utility box includes a rectilinear driven rod partially seated within the utility box and statically mated to the neck rest section, and a mechanism for linearly reciprocating the driven rod along a first vertical travel path defined posterior of the back pad such that the neck rest section is synchronously raised and lowered above the crossbar. In this manner, the back pad remains statically mated to the crossbar while the neck rest section is raised and lowered along a second vertical travel path defined anterior of the first vertical travel path.
