Effectiveness of a New Therapeutic Technique 'Functional Range Conditioning' in Treating Patients With Chronic Non-specific Low Back Pain

It will be a single blind two-arm randomized controlled trial. Saudi men and women aged between 25 - 45 years with a diagnosis of chronic non-specific low back pain will be invited to participate in this study. Subjects who will fulfill the study's criteria and who are willing to participate in this study will be asked to sign an informed consent form. The primary outcome will be the active and passive range of motion (ROM) of the hip internal rotators and it will be measured using digital inclinometer. The secondary outcomes in this study will be the maximum torque of the hip abductors (gluteus medius), concentric at a constant, low-speed, and high-speed. The peak torque and strength will be measured using isokinetic dynamometry, pain intensity will be assessed using a visual analog scale and disability will be assessed using Oswestry disability index. All participants will have their information taken by the principal investigator. Subsequently, participants will randomly be assigned to either the FRC group or the conventional treatment group by the principal investigator. Concealed randomization will be performed by means of a computer-generated table of random numbers. Outcomes will be measured at baseline, week 4 and week 8 for all participants in both groups by an assistant researcher.
