FDA-reported concerns

The FDA reports receiving adverse-event reports involving shocks, burns, bruising, skin irritation and pain with some electrical muscle stimulators. It also notes reports of interference with implanted devices such as pacemakers and defibrillators.

Who needs extra caution

If you have an implanted electronic device, are under medical care, are pregnant, have impaired sensation, or have another condition that could affect safe use, do not rely on a general web guide. Consult the product labeling and an appropriate healthcare professional.

Safe-use habits

  • Read the model-specific manual before first use.
  • Use only on body areas permitted by the manufacturer.
  • Stop if you experience unexpected pain, burns or significant skin irritation.
  • Keep electrodes and accessories in good condition.
  • Do not improvise around contraindications.

Medical claims

Consumer fitness use and treatment of medical conditions are different contexts. A product should not be assumed to treat pain, injury or disease unless its labeling and regulatory status support that use.
