Methods:
Auricular acupressure therapy using Semen Vaccariae or magnetic pellets (Suen et al., 2007).
Semen Vaccariae: a small round seed, with the diameter of each seed about 0.13 cm. Magnetic pellet: an average of –6.58 mT (about 66 Gauss/bead) magnetic flux densities, with a diameter of 0.13 cm.
Protocol:
- Sterilize the auricle of the participant with 75% alcohol before the therapy.
- Apply Semen Vaccariae or magnetic pellets to the most sensitive area of each selected auricular point.
- Detect the sensitive point with an electrical potentiometer to measure auricular electrical resistance.
- Treat both ears alternately.
- Replace Semen Vaccariae/magnetic pellets every 3 days to avoid the possibility of local irritation.
- The full course of the treatment lasted 3 weeks.
7 auricular acupoints:
Shenmen (or Gate of Spirit): The major point for relieving the pain.
Kidney: The kidneys are connected to the low back.
Urinary bladder: To clear and activate the meridians and collaterals at the low back.
Lumbosacral vertebrae, buttock: The most tender points for patients with LBP.
Liver, spleen: To strengthen the tendons and muscles.
Clinical trial records:
60 patients, 60-years old or above, with low back pain (LBP).
Evaluation:
Treatment effects were evaluated with the Chinese Pain Intensity Verbal Rating scale (VRS).
Effects:
Auricular acupressure therapy using magnetic pellets significantly decreased the pain intensity level among the elderly patients with non-specific LBP. The therapeutic effects were sustained during the 2 and 4-week follow-up periods after the therapy.
