Twin Stim Plus 3rd Edition uses



  • Symptomatic relief of acute or chronic pain.
  • Reduction in inflammation.
  • Post-traumatic acute pain and edema.
  • Post-surgical acute pain and edema.
  • Pain relief for back, foot, shoulder, neck, virtually any acute or chronic pain.
  • Relaxation of muscle spasms.
  • Increasing local blood circulation.
  • Muscle re-education.
  • Immediate post-surgical stimulation of calf muscles to prevent deep vein thrombosis (DVT).
  • Prevention of retardation of disuse atrophy.
  • Maintaining or increasing range of motion.



The long-term effects of chronic electrical stimulation with TENS units are not known. However, unlike prescription opioids, TENS unit supplies have only a couple possible adverse effects; namely, skin irritation and electrode burns.


·         This unit should not be used for symptomatic local pain relief unless a pain syndrome has been diagnosed.

·         This unit should not be used where there are cancerous lesions in the treatment site.      

·         Stimulation should not be applied over swollen, infected, inflamed areas or skin eruptions.   

·         Electrodes must not be applied to areas that might cause current/stimulation to flow through the anterior neck or through the head.     

·         Do not use if you have a demand-type cardiac pacemaker or any implanted defibrillator.   

·         This device should not be used over poorly enervated areas.

·         TENS unit supplies should not be used on patients with epilepsy, people with serious arterial circulatory problems in the lower limbs, or patients with abdominal or inguinal hernias.
