HANS for Pain and Addiction
Pain is a major symptom in many medical conditions, significantly interfering with a person's quality of life. An acute pain may become intractable and develop into a chronic pain in which pain is no longer considered a symptom but an illness by itself. Repeated use of narcotic pain killers often leads to the development of opioid addiction which is a complex and protracted health problem.
Choice of acupoints
To treat pain, place one pair of electrodes on the area with pain (the "Ah shi" point, meaning "Ouch, there". The electrodes from the same outlet should be at least 2 inches apart when placed side by side). Place the other pair either on HeGu and LaoGong for upper body pain or on ZuSanLi and SanYinJiao for lower body pain.
Choice of wave forms
For pain, tightness of muscles, and opioid withdrawal syndromes, the default wave form 2/100Hz is the best choice. The wave form 2Hz is found to be more effective for craving. For muscle spasms due to spinal cord injury, AM100Hz is recommended.
Intensity
Use the A+/- and B+/- keys to slowly bring up the stimulation intensity. At the intensity of 5mA, most users start to feel the electric pulse. Users are encouraged to take a higher intensity. The specific intensity level will depend on the acupoint location and the individual's sensitivity.
Dosage
For acute pain or opioid withdrawal symptoms, the recommended maximum total stimulation time is no more than 2 hours (4 standard 30 min sessions) per day for the first 3 days, and then reduce to 30-60 min of total stimulation time per day for the first two weeks. No more than twice a week is recommended. Afterwards, a maintenance treatment of every other day is beneficial. For chronic pain, every other day or twice a week is recommended.
The above recommendations are based on our past clinical experiences. For a better theraputic effect, we encourage users to find their own optimal conditions through experimentation. For more information, please refer to the Frequently Asked Questions.
