1.Primary Outcome
Title Posture Control of Head Position, Shoulder Position and Back Position
Hide Description Forward Head Position (FHP), Rounded Shoulder Position (RSP), and Thoracic spine (T/s)-Lumbar spine (L/s) positions were scored. Subscale scores of 0-3 for each FHP, RSP, and T/s L/s position were obtained. Score 0 was a perfect posture score, Score 1 was 0-1 inches out of alignment. Score 2 was 1-2 inches out of alignment. Score 3 was 2-3 inches out of alignment. Subscale scores were combined for a total score with a minimum value of 0 and a maximum value of 9. 0 being a perfect posture score, 9 being the worst postural score.
