Laser Acupuncture and Acupressure for Low Back Pain

Participants received laser acupuncture on the six selected acupuncture points bilaterally twice a week for 4 weeks. A seed was taped onto each of the three points of the unilateral ear (initially, the left ear), where it remained for five days. Pressing on each of the seeds for one minute three times a day was required, but the stimulation intensity was adjusted depending on the participant's individual tolerance. The de qi sensation appears to be an established intervention efficacy indicator during auricular acupressure. After five days, the seed was removed, and a new seed was taped on the other ear.
