More Information

  • Caution:
    - Federal law (USA) restricts this device to sale by or on the order of a physician so licensed by the State.
  • Contraindications:
    - TENS devices can affect the operation of demand-type cardiac pacemakers. TENS is not recommended for patients with known heart disease without a physician’s evaluation of risk. Do not stimulate over the eyes or carotid sinus nerves. Do not apply TENS for 1. undiagnosed pain syndromes until etiology is established, 2. electrode placement that causes current to flow transcerebrally (through the head).
  • Warnings:
    - This device should be used only under the continued supervision of a physician. TENS is ineffective for pain of central origin, (i.e. appendicitis, hepatitis). TENS is of no cura­tive value; it is a symptomatic treatment which suppresses pain sensation which would otherwise serve as a protective mechanism on the outcome of the clinical process. Safety of TENS devices for use during pregnancy or delivery has not been established. For external use only. Electronic equipment such as EKG monitors and EKG alarms may not operate properly when TENS is in use. The user must keep the device out of the reach of children.
  • Precautions:
    - Avoid adjusting controls while operating machinery or vehicles. Turn the stimulator off before applying or removing electrodes. Long-term stimulation at the same electrode site may cause skin irritation. Use only for the specific pain problem prescribed by the physician. Effectiveness is dependent upon patient selection.
  • Adverse Reactions:
    - Possible allergic reaction to tape or gel. Possible skin irritation or electrode burn under electrode.
