The Evaluation of adding tecar therapy effect on routine physiotherapy treatments compared to placebo tecar and routine physiotherapy treatments on pain, disability and electrical activity of erector spine muscles in patients with non-specific chronic low back pain

The evaluation of adding tecar therapy effect on routine physiotherapy treatments compared to placebo tecar and routine physiotherapy treatments on pain, disability and electrical activity of erector spine muscles in patients with non-specific chronic low back pain

Clinical trial with a control group, with parallel groups, three blinded, randomized, on 32 patients. The rand function of Excel software was used for randomization.

In this study, 32 patients with non-specific chronic back pain are divided into two groups of 16, treatment and control. In the treatment group, 20 minutes of Tecar therapy, 35 minutes of routine physiotherapy (20 minutes of TENS and 15 minutes of IR and exercise therapy) and the control group (placeboTecar and routine physiotherapy) are performed.

Inclusion criteria: Patients with back pain who do not have documentation of discopathy or disc herniation Patients with symptoms of chronic back pain who are between 20 and 60 years old Diagnosis of chronic back pain for at least 12 weeks Visual pain index 4-7 Exclusion criteria: Contraindication of tecar therapy: neoplasm, regional infection, patients with cardiac pacemaker and pregnancy. Active vertebral fracture previous spine surgery Rheumatoid diseases such as rheumatoid arthritis infectious diseases Systemic diseases that affect pain perception, such as diabetes and... Local injection such as (local anesthesia, corticosteroid...) Taking medicines and doing physiotherapy in the last 4 weeks

The intervention group includes Tecar therapy, routine physiotherapy (IR, TENS and exercise therapy). The control group is the same as the intervention group, but Tecar will be done as placebo.

The sampling method in this research is done in the form of simple sampling. Allocation of samples (into two groups) is done randomly using the Stratified Permuted Block Randomization method with 5 blocks of 4 and 8 assigned to two groups 1 BBBAABAA 2 ABAB 3 AABBAABB 4 AABBBABA 5 AABB. Considering A as the routine physiotherapy treatment group and B as the exercise group, the methodologist randomly selects a number between 1 and 5 after each patient enters. The result of the lottery result of the corresponding block number is determined. In the next step, by referring to the above table, the type of intervention (whether it is A or B) is determined. For example, let's assume that the number 3 appears at some point in the lottery, by referring to block three, we can see that before AAB choices were made and now it is the turn to perform intervention B, then, the expert is asked for this patient exercise and Takar should be done together. In the image that the block number appeared in the lottery that all the previous options were completed, the lottery is completed again until the number of duplicate samples is completed.

The main researcher will not divide the samples into two groups, and this work will be done by the research assistant who is a physiotherapy expert, and the information obtained from the data will be provided to the statistical evaluator in a coded and non-recognizable form. And the evaluator will not know about the grouping of people. Also, the intervention is done by another person, and the evaluation before and after the treatment is done by the main researcher, so this study is a thriple-blind one.
