Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Patients with chronic nonspecific low back pain will be randomly divided into two groups: Experimental group (dry needling and routine physical therapy) and control group (sham dry needling and routine physical therapy). Primary outcomes will be pain intensity and functional disability. Postural control and pain pressure threshold will be considered as secondary outcomes.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The aim of this study will be to investigate the effectiveness of dry needling on pain, functional disability, postural control and pain pressure threshold in patients with chronic nonspecific low back pain.
This study will be a double-blind randomized controlled trial. Forty patients with chronic nonspecific low back pain will be randomly divided into two groups: Experimental group (dry needling and routine physical therapy) and control group (sham dry needling and routine physical therapy). Primary outcomes will be pain intensity and functional disability. Postural control and pain pressure threshold will be considered as secondary outcomes. Outcomes will be assessed before and one week after the intervention.
All of the participants will be identified and recruited by posters and word-of-mouth from the university and the surrounding local communities. Eligible participants will be explained about the purpose and the examination involved in this investigation, and all eligible participants will sign a written informed consent before entering the study.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Experimental group
The experimental group will comprise 20 participants with chronic non-specific low back pain. The treatment will include dry needling of the lumbar multifidus muscle and routine physical therapy. The needles will be inserted to obtain local twitch response, and this process will continue until no more local twitch response occurs in each session. Then the needles will be left in place for 20 minutes. Routine physical therapy will include low level laser therapy and motor control training. The treatment will last 3 weeks, 6 sessions, twice a week.
dry needling
The patients will be placed in a prone position with a pillow under their belly to accommodate lumbar lordosis. Two lengths of sterile, disposable, 0.30 mm x 75 mm and 0.30 mm x 50 mm solid filament needle (Tony, China) will be used in this study. The length of the needle for each participant will be selected based on the size of the participant. The needles will be inserted into the lumbar multifidus muscle, 1.5 - 2 cm lateral to the spinous process of two or three painful segments, perpendicular to lamina (after piercing the skin, needles are directed inferomedially). The needles will be inserted to obtain local twitch response, and this process will continue until no more local twitch response occurs in each session. Then the needles will be left in place for 20 minutes.
Control group
The control group will comprise 20 participants with chronic non-specific low back pain. The treatment will include "sham" dry needling of the lumbar multifidus muscle and routine physical therapy. The sham dry needling method consists of the insertion of the needles subcutaneously and no local twitch response will be obtained. The needles will be left in the place for 20 minutes. Routine physical therapy will include low level laser therapy and motor control training. The treatment will last 3 weeks, 6 sessions, twice a week.
sham (placebo) dry needling
The sham dry needling method includes the insertion of the needles subcutaneously and no local twitch response will be obtained. The needles will be left in the place for 20 minutes.
