Abstract: A spinal traction device permits a user to conduct spinal traction therapies, either with or without aid by another, using the user's leg weight and/or leg muscle and/or torso muscle action to apply tensile forces to the spine. The device includes a body support portion on which the user lies in a supine position, and a movable leg support that is coupled to the body support portion. The leg support pivots and/or translates relative to the body support portion in response to the application of leg weight and/or leg muscle and/or torso muscle action to the leg support. Under-arm supports along the body support portion engage the user's underarms to keep the user's upper torso in a substantially fixed position, so that tension is applied to the user's spine in response to movement of the leg support, as it is engaged by the calves and/or backs of the user's legs.
