Radiography and photogrammetry-based methods of assessing cervical spine posture in the sagittal plane: A systematic review with meta-analysis

There are numerous radiography and photogrammetry-based methods of assessing the cervical spine posture in sagittal plane. The choice instrument should be based on scientific parameters such as validity reliability, thus avoiding restrictions to applicability instrument. What used assess plane valid and/or reliable? Systematic searches were conducted following Meta-analysis Observational Studies Epidemiology guidelines. Methodological quality was assessed according Brink & Louw appraisal tool. Twenty-one studies included qualitative analysis. Twenty different calculating found. Two validation measures, 16 inter-rater 17 intra-rater reliability. Fourteen for quantitative meta-analysis shows that arrow lordosis present very high In radiography, also showed Cobb method (inferior C2 - inferior C7), (middle C1 absolute rotation angle, Gore angle (C2-C7) C7) This systematic review presents an overview respective information panorama facilitates when conducting or assessment addition, it need new investigate accuracy precision these their possible use larger studies.
