Normal range of lumbar spine flexion in adult Nigerians

One hundred patients, fifty males and fifty females, without any back pain or disease, were studied. Their ages ranged between 14 years and 70 years. The lumbar flexion measurement was taken using the MacRae and Wright modified Schober's method. The values for males were higher than females and the younger the patient, the higher was the value of the lumbar flexion, up to the third decade. The method could be adopted to show improvements during treatment of low back pain by orthopaedic and physiotherapic practices.
