Most of the outcome question naires had a mixed content reflecting various constructs such as pain and symptoms , sleep disturbances , psychological dysfunctions , physical impairments , and social functions .
STUDY DESIGN A systematic literature review of outcome question naires design ed for assessing functional status or disability in patients with low back pain .
OBJECTIVES To provide a comprehensive overview of all functioning/disability question naires used in recent years and to explore how the main concept(s ) was described or defined in the original paper , the content or the domains of disability , and the measurement properties of the question naires .
SUMMARY OF BACKGROUND DATA A number of clinical tools design ed for evaluating the functional status of patients with low back pain have been developed .
Only a few have been review ed earlier , and there has been little focus on the content reflected in the question naires .
Isokinetic Measurement of Trunk Muscle Strength in Women with Chronic Low-Back Pain
Bayramoğlu M , Akman MN , Kılınç Ş , Çetin N , Yavuz N , Özker R : Isokinetic measurement of trunk muscle strength in women with chronic low-back pain . Am J Phys Med Rehabil 2001;80:650–655 . Objectives : To investigate the relationships among chronic low-back pain and obesity , total spinal range of motion , and trunk muscle strength . The short-term impact of trunk muscle strengthening exercises on this condition was also examined . Design : A controlled , prospect i ve study of trunk muscle strengths of patients with chronic low-back pain and the short-term impact of exercise on strength . The study group consisted of 25 female patients who had been experiencing low-back pain for at least 3 mo , and the control group included 20 age-matched women without known low-back trouble . The Davenport Index was used to calculate the body mass indexes of all subjects . The Oswestry Disability Question naire was used to assess pain in the study group . Full flexion and extension ranges of motion were measured , then isokinetic measurements of trunk muscles were performed at 60- , 120- , and 180-degrees/sec velocities . Isometric measurements were also recorded for both flexors and extensors at a 60-degree angle . Results : Increased body mass index and decreased trunk muscle strength were found to be directly associated with chronic low-back pain ( P < 0.05 ) . After a 15-day st and ard trunk strengthening exercise program in the patient group , trunk muscle strength was found to be increased ( P < 0.05 ) . Conclusions : Obesity and decrease in trunk muscle strength are important factors in chronic low-back pain , and a trunk muscle strengthening program will be helpful in reducing the pain
