A buoyancy-based cervical traction system has a floatation and a head rest supported by the flotation system. The head rest is adapted to support a person's head above the neck and apply traction to the neck when the person is in a body of liquid. The system has a position adjustment system adapted to allow selective adjustment of the position at which the person's head rest will be relative to an upper surface of the liquid when the person and the cervical traction system are in the liquid, the person's head is supported by the head rest, and the cervical traction system and person are floating in the liquid at equilibrium.

A device for facilitating or enhancing proprioceptive feedback during breathing and related exercises includes a user attachment component attachable to a user about the thorax. Two elongate tensile members are connected at proximal ends to the user attachment component at points essentially just below the armpits of a user. These two elongate tensile members are connectable at their distal ends to the feet of the user. Another two tensile members are connected at their proximal ends to a back portion or strap of the harness and at their distal ends to or about the user's hands.

A headgear for neck rehabilitation and weight training includes first and second straps forming a loop for wrapping a forehead of a user, an upper strap device abutting a top of a head of the user, and a lower strap abutting a chin of the user. The second strap is coupled to the first strap and is adjustable in length to fit the head circumference of the user. The upper strap device is adjustable in length to fit the spacing between the forehead and the top of the head of the user. The lower strap is coupled to the loop formed by the first and second straps and is adjustable in length to fit the chin of the user. The headgear can be assembled with one of two rehabilitation accessories in a rehabilitation mode or assembled with a weight training accessory in a weight training mode.
