Brief Summary:
The aims of this study are to examine the effectiveness of functional range conditioning in patients with chronic non-specific low back pain in terms of improving hip internal rotation and strength of the hip abductors, and reducing pain and disability.

Condition or disease Intervention/treatment Phase
Chronic Low Back Pain Behavioral: FRC exercise Behavioral: Conventional Exercise Not Applicable

Detailed Description:
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.

Arm Intervention/treatment
Experimental: FRC group
This group will receive FRC exercise.
Behavioral: FRC exercise
The program will consist of hip joint controlled articular rotations (CARs) in standing position for 3 - 5 repetitions. Then, the participant will sit on the floor in what is called 90/90 position which is sitting in hip and flexion in 90 degrees for both the lead (front) and trail (side) leg. The participant will perform a Progressive and regressive angular isometric loadings (PAILs and RAILs) for the trail leg to increase the range of internal rotation, the contraction will be performed three times and the holding of the position will be for two minutes. After expanding the range, the participant will perform Progressive and regressive angular loadings (PALs and RALs) isometric contractions in form of a passive range hold for internal rotation and abduction, for 3 - 5 times.

Experimental: Conventional treatment
This group will receive conventional exercise.
Behavioral: Conventional Exercise
The conventional training program in this study will be the routine training for increasing the hip rotation. By screening the scientific literature, the conventional training found to consists of static stretching and strengthening using body weight and/or a band and the time of holding a stretch is about 30 seconds. For that the flexibility exercise will consist of progressive stretching from a prone position (leg fall in a stretch), the participant will perform 3 - 5 repetitions with 30 seconds hold or as tolerated. The strengthening exercise consists of hip abduction (hip opening) using a band or ankle weight from side lying for 10 - 12 repetitions 3 times.

Primary Outcome Measures :
  1. Passive range of motion (Hip internal rotation) [ Time Frame: Change from baseline passive hip internal range of motion at 8 weeks ]
    It will be measured using digital inclinometer

Secondary Outcome Measures :
  1. Strength of the hip abductors (gluteus medius) [ Time Frame: Change from baseline hip abductors strength at 8 weeks ]
    Strength of the hip abductors will be measured using hand held dynamometer or isokinetic dynamometry,

  2. Pain Intensitiy [ Time Frame: Change from baseline pain intensity at 8 weeks ]
    Pain intensity will be assessed using visual analog scale (VAS) (0 - 10 cm with 0 indicates no pain and 10 indicates the worst pain).

  3. Functional disability [ Time Frame: Change from baseline functional disability at 8 weeks ]
    Functional disability will be assessed using Oswestry disability index. Each item in the questionnaire is scored on a 0-5 scale with zero indicating the least amount of disability and the 5 indicating most severe disability.The scores for total items answered are summed, and multiplied by two to get the index (range 0 to 100). Zero indicates no disability and 100 indicates maximum possible disability.
