ASSESSMENT OF VENTILATORY FUNCTION IN PATIENTS WITH DIFFERENT CAUSES OF CHRONIC LOW BACK PAIN

Abstract

Study objective: the purpose of this study was to assess the effect of chronic low back pain with different causes on ventilatory function. Setting and participants: One hundred and fifty patients with chronic low back pain. Their age ranged from 30 to 50 years old. Their BMI < 30 Kg/ m.

Clinical assessment was done to exclude any other pathological conditions. Evaluation of participants included body mass index, waist circumference and Visual analogue scale. Assessment of ventilatory functions were done by using spirometry. Results: The results showed that all groups of chronic low back pain a statically significant decreased in all ventilatory parameters. Conclusion: These results suggested a reduction of respiratory function in lumbar disc prolapse group more than other two groups. Because of pain and muscle spasm.
