Spinal posture assessment and low back pain.

Postural assessment can help doctors and therapists identify risk factors for low back pain and determine appropriate follow-up treatment. Postural alignment is not perfectly symmetrical, and small asymmetries can instead represent norms and criteria for postural evaluation. It is necessary to comprehensively observe patients' posture in all directions and analyze the factors related to posture evaluation. The results of reliability show that in general intra-rater reliability is higher than inter-rater reliability, and inclinometers are being more reliable than other instrumentations. Some common postural problems can cause lumbar discomfort, and prolonged poor posture is a potential risk factor for lumbar spine injuries. On the basis of previous studies on posture evaluation, a unified standardized method for posture evaluation must be established in future research.
