ABSTRACT
Posture is the alignment of the musculoskeletal system at rest (static) or during movement (dynamic) (Posture Committee, 1947; Twomey & Taylor, 1987). Therefore, good posture can be defined as the optimal arrangement of body segments and supporting structures of the spine to minimise energy expenditure and injury. Kritz and Cronin (2008) defined good posture as a state of equilibrium: muscular and skeletal balance. Correct structural alignment will ensure that minimal neuromuscular activity and joint loading (economical advantage) is required to maintain body position against gravitational stresses. Additionally, a state of musculoskeletal balance allows optimal muscular efficiency for force production during locomotion and physical activity (Kritz & Cronin, 2008).
