The effect of iliopsoas muscle dry needling technique on the clinical symptoms of subject with non-specific low back Pain

Investigate the effect of dry needling on the trigger points of the iliopsoas muscle in patients with non-specific chronic back pain.

Clinical trial with control group, with parallel groups, Tow-blinded, randomized, without phase on 40 patients, randomization allocation software was used for randomization

Patients will be divided into two groups by the table of numbers. The first group will receive dry needling of the iliopsoas muscle during 6 sessions. At the same time, they will also benefit from conventional physiotherapy treatment, but the control group will only use conventional physiotherapy treatment. The location of the project will be at the Physiotherapy clinic of Asadabadi Hospital.

Inclusion criteria: 1) People between 30 and 65 years old 2) Chronic back pain that lasts 3 months or more 3) People with a disability score of >40 in the QBPDS questionnaire) 4) Not receiving any other physiotherapy treatment while participating in the study. 5) The presence of a trigger point in the iliopsoas muscle

The intervention group includes patients with non-specific chronic back pain, whose conventional physical therapy includes continuous ultrasound treatment with a frequency of 1 MHz and intensity of 1.5 for 6 minutes, TENS burst electric current with a frequency of 2 Hz and diversion of 100 µs for 20 minutes, and the use of hot packs at the same time. Apply with current. Exercises are taught in the clinic under the supervision of a physiotherapist. 6 sessions of dry needling treatment are also done for them. The control group includes patients with non-specific chronic back pain who only receive conventional physiotherapy.

I want to change the expected start date of the patient intake to 2024-10-22 due to the university's inability to solve the problems encountered in order to prepare the tools needed to measure this plan, and subsequently change the expected end date of the patient intake to 2025-03-05.

Randomization is done by someone outside the research team with a 1:1 parallel allocation method, which uses a computer randomization program to assign participants to groups, using blocks of four and six. Then he uses opaque sealed envelopes and hides the allocation of groups with the method pre-labeled with the letters A and B.) They will be placed in two control and intervention groups.

Double-blind, participants: In the control group, patients are told that routine physical therapy is the only treatment. Outcome assessor: The person who assesses the patients does not know whether they belong to the control or intervention group Data analyst: The person who evaluates the data of the two groups does not know whether they belong to the contr
