Assessment of the normal range of the angular and linear movement at lumbo scral region in Egyptian people

ABSTRACT

The range of linear and angular movements at the lumbo-sacral region in normal Egyptian people was assessed and compared with figures with other similar works overseas. The study was conducted on 90 cases who had no previous serious lumbar problem. The assessment included history taking, clinical examination and radiological examination including antero-posterior and lateral oblique views to the lumbo- sacral region and motion films [flexion and extension] for the same region. The results denoted that the mean of lumbar movements ranged from 45 to 72 degrees and the mean of horizontal displacement at the lumbar spine ranged from 0 to 4 mm or from 0 to 10% of the antero- posterior diameter of the vertebra
