A traction bed includes (a) a frame upon which an individual is supportable, (b) a first single-sided lever arm pivotably coupled to the frame at a location proximate both a first end of the frame and a first side of the frame, wherein the first single-sided lever arm is configured to be coupled to an arm of an individual, (c) a second single-sided lever arm pivotably coupled to the frame at a location proximate both a second end of the frame and the first side of the frame, wherein the second single-sided lever arm is configured to be coupled to a leg of an individual, and (d) a control system operable to direct a force onto each of the single-sided lever arms to pivot the single-sided lever arms relative to the frame, wherein the force directed to the first single-sided lever arm is separately variable from the force directed to the second single-sided lever arm.
