Ideal For

These electrodes are well suited for physical therapists, occupational therapists, and athletic trainers who use TENS or NMES devices for pain management, muscle re-education, and neuromuscular rehabilitation and need a reliable, reusable electrode that maintains adhesion through multiple treatment sessions. They are a practical choice for sports medicine clinicians and rehabilitation facilities that treat athletes or active patients in warm, humid environments where standard electrodes may lose adhesion, as the Model 690 is specifically formulated for performance in high heat and humidity conditions. Home TENS users managing chronic pain conditions such as low back pain, arthritis, or neuropathy will benefit from the reusable, self-adhesive design, which reduces the cost per treatment compared to single-use electrodes. They are also appropriate for FES programs targeting upper or lower extremity muscle groups in patients with neurological conditions such as stroke, spinal cord injury, or multiple sclerosis.

Frequently Asked Questions

What devices are these electrodes compatible with?
The Axelgaard Model 690 electrodes are compatible with standard TENS, NMES, and FES devices that use a standard lead wire connector. Confirm connector compatibility with your specific device before ordering. Most clinical and consumer TENS/NMES units use a standard 2mm pin or snap connector.

How many times can these electrodes be reused?
The number of uses depends on skin preparation, storage, and care. To maximize electrode life, clean the skin thoroughly before each use, store electrodes on their original backing or a clean surface between uses, and avoid folding or creasing the electrode. Replace electrodes when adhesion is no longer sufficient to maintain skin contact during treatment.

Why are these electrodes effective in high heat and humidity?
The Model 690 uses a specialized adhesive formulation that maintains skin contact and conductivity in warm, humid conditions where standard electrode adhesives may soften or lose grip. This makes them particularly useful for treating athletes, patients in warm clinical environments, or anyone who perspires during treatment.

How do I care for and store these electrodes?
After each use, replace the electrodes on their original plastic backing or a clean, non-porous surface. Store in a cool, dry location away from direct sunlight. Clean the skin before each application to remove oils, lotions, and perspiration that can reduce adhesion and conductivity.
