TENS Units (Nerve Stimulation)
Transcutaneous Electrical Nerve Stimulation (TENS) delivers micro-current signals to block pain signals to the brain and stimulate endorphin production for chronic back, joint, and nerve pain relief.
EMS Machines (Muscle Stimulation)
Electrical Muscle Stimulation (EMS) targets motor nerves to cause muscle contractions, helping prevent muscle atrophy, improve circulation, and re-educate muscles during post-injury recovery.
Replacement Electrodes (Pin & Snap)
Ensure optimal conductivity and treatment comfort with reusable self-adhesive electrode pads, available in standard 2mm pin connection and snap-style formats.
Lead Wires, Gels & Accessories
Keep your electrotherapy setup operational with replacement lead cables, conductive skin gels, carrying cases, and long-lasting unit batteries.
What to Check Before Ordering
Confirm whether you need a standalone TENS unit for pain relief, an EMS unit for muscle active recovery, or a combination TENS/EMS device. Verify channel requirements (dual-channel units allow control of 4 electrode pads simultaneously).
For replacement accessories, check whether your device utilizes standard 2mm piggyback pin connectors or snap connectors to ensure pad and cable compatibility.
Complete your pain management protocol with topical pain gels, back braces & lumbar supports, and hot & cold therapy packs.
Frequently Asked Questions
What is the main difference between TENS and EMS?
TENS stimulates sensory nerves to block pain signals and relieve discomfort, whereas EMS stimulates motor nerves to cause muscle contractions for muscle strengthening, spasm relief, and rehabilitation.
How long do TENS electrode pads last?
Reusable electrode pads typically last 15 to 30 applications depending on skin preparation, storage, and gel quality. Clean your skin before use and store pads on their plastic film to maximize adhesion.
How do I know if I need pin or snap electrodes?
Check the end of your device's lead wire: if it has a thin 2mm male metal pin, choose pin-style electrodes. If it has a round button-like connector, select snap-style electrodes.
Can TENS machines be used every day?
Yes, TENS units are non-invasive and can be used multiple times a day as recommended by your healthcare practitioner. Rotate electrode placement slightly between sessions to avoid skin irritation.
Can electrotherapy accessories be returned?
Due to hygiene standards, opened electrode pads and skin gels are non-returnable. Please verify your device connector format before ordering, or contact TherapySupply.ca for assistance.
