Type of acupuncture therapy and description
Acupuncture
  An ancient healing practice with roots in Chinese medicine
  It involves inserting special needles into specific points (called acupoints) in the skin to relieve pain and other symptoms.
  Therapeutic effects of acupuncture are thought to be due to the activation of neural pathways and the release of neurotransmitters.
Electroacupuncture
  A variation of acupuncture that involves applying a small electrical current to the inserted needles.
Transcutaneous electrical nerve stimulation (TENS)
  A non-invasive technique that involves applying electrical stimulation to the skin through electrodes placed on the skin.
  Flat-surface electrodes are used. No needles are inserted.
Microcurrent electrical nerve stimulation
  A similar technique to TENS but uses a much lower level of electrical stimulation.
  Uses weak electrical currents (<1,000 µA).
Silver Spike Point therapy
  A more recent form of needle-less acupuncture.
  Uses low-frequency electrical stimulation applied to the acupuncture points using special electrodes.
  It uses “pointed” cone-shaped electrodes made of silver.
  The treatment typically lasts between 15 and 30 minutes, and multiple sessions are usually required.
