Two TENS units in one: The InTENSity Twin Stim III
Technically the InTENSity Twin Stim III is not two TENS units in one, but a TENS unit plus an EMS unit. Nevertheless, the point remains valid. This is a twofer that provides Transcutaneous Electrical Nerve Stimulation and Electronic Muscle Stimulation in order to both relieve chronic and acute musculoskeletal pain and re-educate, massage, and build muscle.

As is the case of most TENS units, this one is ideal for relieving the symptoms of chronic intractable pain, as well as post-traumatic and post-surgical pain, relaxing muscle spasms, preventing muscle retardation of disuse atrophy, increasing local blood circulation; re-educating muscles, immediate post-operative stimulation, and maintaining or increasing range of motion. But, and this bears repetition, the most important characteristic about this product is that it combines TENS and EMS therapy. Well, it doesn’t literally combine them; it’s not as if you’d be getting TENS and EMS stimulation at the same time, though you may easily switch between one and the other. You get the idea.
You may be in a hurry to use this device to relieve pain, but keep in mind that the pain must be diagnosed by a physician first. TENS units should not be used for pain syndromes of unknown origin, or for pain of central origin on which it has no effect. Also, patients with epilepsy, serious arterial circulatory problems in the lower extremities, or abdominal or inguinal hernia should not use it either.
· Do not use in areas where there are cancerous lesions, or over swollen, infected, inflamed areas or skin eruptions.
· Do not use over poorly enervated areas.
· Consult your doctor before you use TENS units if you have heart disease or are pregnant.
· Use under the supervision of a doctor.
· Do not use near shortwave or microwave therapy equipment.
· Do not use in a highly humid environment like a bathroom.
· Do not use in areas lacking normal sensation.
· Keep electrodes separate during stimulation to avoid burns.
· Do not operate the device with sharp objects like pencil point or ballpoint pens.
· Turn unit off before applying or removing electrodes.
· Read the full manual for more warnings and contraindications.
