Posture Training is instruction in the correct biomechanical alignment of the body to reduce undue strain on muscles, joints, ligaments, discs, and other soft tissues. There is an ideal posture, but most people do not have ideal posture. Therapists educate patients about the importance of improving posture with daily activities. Stretching and strengthening exercises may be prescribed to facilitate postural improvement and to prevent further disability and future recurrences of problems.
