  • Page 4: Introduction

    1. INTRODUCTION 1.1 General The Twin Stim Plus OTC is a portable electrotherapy device featuring two therapeutic modes: Transcutaneous Electrical Nerve Stimulator (TENS) and Neuromuscular Electrical Stimulation (EMS), which are used for pain relief and electrical muscle stimulation. The stimulator sends gentle electrical current to underlying nerves and muscle group via electrodes applied on the skin.
  • Page 5 How TENS Works There is nothing “magic” about Transcutaneous Electrical Nerve Stimulation (TENS). TENS is intended to help relieve pain. The TENS device sends comfortable impulses through the skin to stimulate the nerve (or nerves) in the treatment area. In many cases, this stimulation will greatly reduce or eliminate the pain sensation the patient feels.
  • Page 6: Indication For Use

    1.3 Indication for Use The Twin Stim Plus OTC Stimulator is designed to be used for temporary relief of pain associated with sore and aching muscles in the shoulder, waist, back, neck, upper extremities(arm)and lower extremities(leg) due to strain from exercise or normal household work activities.

  • Page 10 CAUTION (CONTINUED) CAUTION WHILE USING THE STIMULATOR • If the stimulator is not functioning properly or you feel discomfort, immediately stop using the device. If any type of shock or burn should occur, stop using immediately and consider seeking medical attention (if necessary). •...
  • Page 11 GENERAL PRECAUTIONS • The long-term effects of electrical stimulation are unknown. • Apply stimulation to only normal, intact, clean, dry, and healthy skin. • TENS is NOT effective in treating the original source or cause of the pain, including headache. •...
  • Page 12 POSSIBLE ADVERSE REACTIONS • DO NOT use to treat one region for extended periods of time (more than 30 minutes a session, up to 2 times/day) or muscles in that region may become exhausted and sore. • You may experience skin irritation and burns beneath the stimulation electrodes applied to your skin.
