About iSTIM
iSTIM describes itself on istim.com as a medical instruments company in Los Angeles, dedicated to electrotherapy. Its range is built around TENS and EMS machines, from analog and digital two-channel units to wireless and heat-equipped models, alongside Kegel exercisers, a foot stimulator, and the electrode pads, lead wires and adapters that go with them. The company says its electrode pads use Japanese Sekisui gel, and it packs an instruction manual with each device.
Two iSTIM products stood out for us. The EV-805 is a rechargeable TENS and EMS combination unit with four independent channels and 24 preset programs. The WeTrac is a cervical neck traction device that uses a knob-turning mechanism to apply controllable force up to 50 pounds, and istim.com lists it as a patented product made in Taiwan. Together they show a brand that covers both electrical stimulation and mechanical traction for home use.
