BACKGROUND AND AİMS: Sustained Natural Apophyseal Glide (SNAG), when indicated, can provide immediate pain relief and improvement in range of motion (ROM). The aim of this study was to investigate the outcomes of adding lumbar SNAG to a conventional physiotherapy program (CPP) for chronic nonspecific low back pain (CNSLBP).
METHODS: Thirty-six female participants with CNSLBP were randomly divided into 2 groups. The study group (aged 40.56 ± 5.97, 18 subjects) received a CPP consisted of hotpacks, ultrasound and TENS applications (5 times per week) plus lumbar SNAG (3 times per week) and the control group (aged 39.44 ± 5.08 7.7, 18 subjects) received the same CPP without SNAG for 3 weeks. Outcome measures were pain, range of motion, fear avoidance behaviour and function measured by Visual Analog Scale, Back ROM II, Fear Avoidance Behaviour Questionnaire (FABQ) and Rolland Morris Disability Index (RMDI). Measurements were recorded before, after and 3 month after the end of the treatment. 
REULTS: Comparing test scores indicated that the study group had significant improvement in all measurement parameters (p< 0.05) and control group in pain intensity at extention activity, extention ROM, FABQ and RMDI scores (p=0.02, 0.016, 0.006,0.029) respectively. Acording to delta scores, adding SNAG to the conventional program resulted in higher improvement in terms of all measurement parameters (p< 0.05) accept extention ROM (p=0.197).
CONCLUSSIONS: This study indicated that adding SNAG to conventional physiotherapy program in the treatment of CNSLBP may result in greater improvement of pain intensity, flexion ROM, fear avoidance behaviour and function.
