The purpose of this study is to investigate the longitudinal effects of different trigger point acupuncture stimulation conditions on pressure pain threshold and subjective pain intensity in individuals with chronic low back pain, and to identify stimulation conditions associated with sustained analgesic effects following a single acupuncture intervention.
Efficacy
Change in Pressure Pain Threshold (PPT)
Assessment time points:Baseline, immediately after intervention, 1 day, 3 days, and 1 week after intervention
Subjective pain intensity assessed using the Numeric Rating Scale (NRS)
Tissue stiffness
Assessment time points:Baseline, immediately after intervention, 1 day, 3 days, and 1 week after intervention
Interventional

Intervention 1: Single-needle trigger point acupuncture in the lumbar multifidus muscle with 10-minute needle retention.
Intervention 2: Multiple-needle trigger point acupuncture within the trigger point region of the lumbar multifidus muscle with 10-minute needle retention.
