InTENSity Twin Stim IV Digital TENS & NMES Therapy Device

The InTENSity Twin Stim IV is the latest standard in portable multifunction electrotherapy, offering patients two proven modalities in one ergonomic device: TENS (Transcutaneous Electrical Nerve Stimulation) for pain relief and NMES (Neuromuscular Electrical Stimulation) for muscle re-education, strengthening, and spasm reduction.

Equipped with pre-set, body-part-specific programs and a fully customizable mode, the Twin Stim IV guides patients step-by-step through their treatment to ensure safe and effective therapy throughout the healing cycle. Users can easily adjust treatment time, pulse rate, pulse width (duration), cycling time, and contraction/relaxation/ramp settings for a tailored experience.

The device includes a powerful rechargeable lithium-ion battery, making it ideal for use at home, at work, or on the go.
