Shortwave Diathermy (SWD): A Deep Heat Revolution
Shortwave Diathermy (SWD) is a pioneering electrotherapy technique that uses high-frequency electromagnetic waves to generate heat deep within the body's tissues. SWD can effectively target large muscle groups, tendons, and joints that are several centimeters below the skin, unlike hot packs and other superficial heat sources.

iStim EV-805 Troubleshooting Guide: Q&A for No Output, Pads, Channels & Settings
The iStim EV-805 is unusual among portable TENS/EMS devices because four independently controlled channels, multiple stimulation modes, and two timer groups create more troubleshooting possibilities than a basic two-channel TENS unit.
Latex-Free Hydrogel in Our TENS Electrodes: The Documentation
Our Balego® TENS/NMES/FES electrodes use hydrogel that contains no natural latex protein. For customers asking about latex-free TENS pads, this is the specific material statement we can share, together with its source.
How Deep Does NMES Penetrate? Electrode Size and Current
Surface NMES does not have a universal penetration depth in inches or centimeters. Current amplitude, electrode geometry, placement, and the tissues beneath the pads all influence which nerves are recruited. There is no dependable conversion such as “20 mA reaches one inch” or “doubling pad size doubles depth.”
Can NMES Reach the Lumbar Multifidus? Electrical Stimulation, Electrode Placement & Device Selection
Quick answer: Yes. Surface neuromuscular electrical stimulation (NMES) has been shown in ultrasound studies to produce measurable activation and thickening of the lumbar multifidus in some people. However, a surface stimulator cannot guarantee selective recruitment of the deepest multifidus fibers. Electrode position, pulse characteristics, stimulation intensity, individual anatomy, and tolerance all determine which lumbar muscles are recruited.
