The purpose of this study is to investigate the effects of trigger point acupuncture and electroacupuncture applied to ultrasound-identified myofascial pain-related tissues on peripheral sensitization in patients with chronic low back pain. Pressure pain threshold will be assessed as an indicator of peripheral sensitization, and changes will be compared among acupuncture, electroacupuncture, and no-treatment control conditions.

| Maneuver |
Two disposable stainless-steel acupuncture needles will be inserted into trigger points within the lumbar multifidus muscle identified using ultrasonography and retained in situ for 10 minutes.
Two disposable stainless-steel acupuncture needles will be inserted into trigger points within the lumbar multifidus muscle identified using ultrasonography, and low-frequency electrical stimulation will be applied between the needles for 10 minutes.
