Design outcomes

Primary

MeasureTime frame
Visual analog scale (VAS): Rated zero (painless) to 10 (most severe imaginable pain) of lumbar. Timepoint: The visual analog scale of pain is measured by the assessor before the intervention and every three sessions until the end of treatment, and one month after the end of treatment. Method of measurement: In this study, pain is determined on a visual analog scale with a score of zero (painless) to 10 (the most severe pain imaginable for patients). The average pain in the last 7 days is the number of VAS.

Secondary

MeasureTime frame
Functional disability. Timepoint: Before the start of treatment by the assessor and the end of treatment and one month after the end of treatment. Method of measurement: In this study, the functional disability of the score obtained from the localized and Persianized Oswestry questionnaire, which was validated by Mousavi et al. In 2006.;Pressure pain threshold. Timepoint: Before the start of treatment by the assessor and the end of treatment and one month after the end of treatment. Method of measurement: In this study, an algorithm will be used to measure the pressure threshold of pain. The algometer will record each point three times and an average of numbers per point will be written finally. 2 and 5 cm outside the first lumbar vertebra, 2 and 5 cm outside of the third lumbar vertebra,2 cm outside of the fifth lumbar vertebra bilaterally, on the common peroneal nerve (which comes from behind the fibula bone and reaches the front of the neck bone) and tibial nerve (outside the tibial artery) and the sciatic nerve (between the ischial tuberosity and the large trochanter deep in the gluteus maximus muscle), obtained at the moment of pain onset by participants, by algometer, in Newtons per square centimeter.;Range of motion. Timepoint: Before the start of treatment by the assessor and the end of treatment and one month after the end of treatment. Method of measurement: In this study, the range of motion is the active movement of the lumbar region forward (using Schubert test) and the SLR range of motion of the affected lower limb (using a goniometer).
