Comparison of effect of strengthening exercises and core stability exercises on lumbopelvic kinematic and disability while lifting among patients with non-specific chronic low back pain

The aim of this study was to compare the effect of strengthening exercises and stabilization exercises on disability and lumbopelvic rhythm in patients with chronic non-specific low back pain.

Randomized controlled trial, 2 parallel intervention groups and a control group, single blinded, including 60 patients, randomization will be done by the random blocks.

The place of accuring the study is the Neuromuscular Rehabilitation Research Center of medical university of Semnan. The patients will be assessed by the Oswestry questionnaire and motion analysis device at the beginning and the end of the study. intervention will be done as strengthening and core stability exercise therapy in two groups. The assessor and the analyzer are blinded and the analysis and the assessment will be done without bias.

Including criteria contains at least 18 years and at most 45 years old for paitients, chronic low back pain (at least 12 weeks long) and visual analogue scale of at most 3 units. Excluding criteria contains any exercise therapy contraindications, neoropathic lesions, acute and subacute involvements, fractures, surgeries, cancers and pregnancy.

This study has two groups of intervention and a group of control. One group receives strengthening exercises, the other receives core stability exercises and the control group doesn't receive interventions. After warming up using stretching exercises, each patient receives 8 exercises during 3 sets and 10 repetitions. At the end patient does the cool down exercises. Exercises result in increasing strength or stability in abdominal or lumbar region. Each treatment session lasts about one hour and each patient has 18 sessions of exercise therapy .The duration is six weeks and the interval is one day.

Disability, kinematic of lumbopelvic rhythm

The study will be conducted randomly using block randomization method. Steps of block randomization: 1-Block Design: First, the blocks are designed. For each block size (in this study we have 3 groups and we consider the block size to be 3) we create all possible states. Initially, random blocks consisting of 3 groups are designed in different allocation orders, which include 6 different modes: {Control, Stability, Strengthening} {Control, Strengthening, Stability} {Stability, Control, Strengthening} {Stability, Strengthening, Control} {Strengthening, Control, Stability} {Strengthening, Stability, Control}  2. Allocation of participants: Then, one of the above blocks will be randomly selected by lottery. We then determine the allocation of the intervention or treatment to the groups based on the order in that block. For example, if your chosen block is {Control, Stability, Strengthening}, then the first participant will be assigned to the control group, the next two participants will be assigned to the stability and strengthening group, and this will continue until all the people are assigned to the groups.

This study is single-blinded. The assessor which in this study is the researcher, does the assessment of patients before and after the intervention. She's not aware of the group that each patient is in. Also the data will be given to the analyzer as first, second and third group and she is not informed which groups are the intervention groups.

Data related to the main outcome such as tables of before and after of variables can be shared.

Beginning of the access period will be six months after the results are published

The data will be available to both researchers working in universities and people working in physiotherapy clinics.
