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

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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
Change from baseline passive hip internal range of motion at 8 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
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,
Change from baseline hip abductors strength at 8 weeks
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).
Change from baseline pain intensity at 8 weeks
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.
Change from baseline functional disability at 8 weeks
