Ankylosing spondylitis (AS) is a sickness that affects young people, men are more frequently affected than women. Progression of AS pain, stiffness, postural changes including loss of normal lumbar lordosis, forward positioning of the neck and exaggerated kyphosis. Here researcher described a 40-year woman who had complain of gradually progressive low back pain which awoke her at night, stiffening in the morning and deformity of the spine and hip. From subjective and objective evaluation and investigation the case was diagnosed as ankylosing spondylitis with physical impairment, social disturbance and depression. The multidisciplinary team then referred case to the Department of Physiotherapy at KC Hospital & Diagnostic Center Ltd. In Daskhinkhan, Uttara, Dhaka. The physiotherapist assesses the case through different clinical reasoning process and set a management plan with proper education and advice. Initially the patient was markedly handicap with severe pain and various disability. After the 8th week of intervention, there was an improvement in pain reduction both at rest and during movement, as well as improved range of motion. In addition, disability status also progressed from 60% to 20% and now patients can participate in daily activities. The clinical reasoning process with evidence- based physiotherapy plays a vital role to find out the biopsychosocial factor and the management of Ankylosing Spondylitis.
