Electrical Stimulation (TENS & NMES) for FCE Recovery
Two different therapies with the same equipment — understanding which your dog needs and when
The crucial distinction: TENS vs. NMES
These two therapies use similar-looking devices and similar electrode-and-gel-pad setups, but they do fundamentally different things and are used at different stages of recovery. Understanding the difference will help you ask the right questions of your rehab vet.
TENS — Transcutaneous Electrical Nerve Stimulation
TENS targets sensory nerve fibers. A mild electrical current is delivered through skin-surface electrodes, stimulating faster sensory nerves and “overloading” the interneurons — interrupting the transmission of pain signals to the brain. The result is analgesia: pain relief.
TENS does not cause meaningful muscle contraction. It is primarily a pain management tool. For FCE dogs — who are typically painless — TENS is less central to recovery than NMES. However, it does have value for dogs experiencing compensatory muscle soreness from asymmetric movement patterns.
Effect duration is relatively short (typically under an hour), which is why it is often used during therapy sessions rather than as a standalone daily treatment.
NMES — Neuromuscular Electrical Stimulation
NMES targets motor nerve fibers and muscle tissue. The electrical current mimics the signal the central nervous system would send to cause a muscle to contract — creating actual muscle contractions in limbs that the dog cannot voluntarily activate.
This is the critically important therapy for FCE recovery. Here is why:
With NMES electrodes placed on the rear limbs to stimulate normal muscle contracture while waiting for the spinal cord to heal, loss of 50% of the muscle mass of the rear leg muscles (which occurs within 3 weeks of spinal cord injury) can be substantially prevented. The muscles that have lost neurologic function can regain up to 33% of their strength with NMES.
That figure — 50% muscle mass loss within 3 weeks — is the reason NMES matters for FCE dogs. Every week without voluntary movement is a week of atrophy. NMES provides a partial substitute for that voluntary contraction, keeping the muscle fibers active and maintaining mass while the nervous system recovers.
Additionally, NMES appears to send neurological impulses up through the contracting muscle to the spinal cord — potentially stimulating the damaged area and contributing to nerve repair at the injury site.
What the research shows
Electrical therapy can aid in the rehabilitation of pets with spinal cord injuries by supporting muscle activation and nerve function. NMES targets muscle contractions to build strength and prevent atrophy in injured or post-operative pets.
The veterinary rehabilitation textbook chapter on electrical stimulation (Veterian Key) notes that NMES has been used to increase joint mobility, decrease joint contracture, decrease edema, enhance circulation, minimize disuse atrophy, improve muscle strength, and facilitate motor relearning in patients with neurologic conditions including spinal cord injuries.
A clinical principle supported across multiple veterinary rehabilitation practices: since animals cannot use the muscle by themselves due to paralysis or nerve damage, NMES creates muscle contractions for them. Progress to function is much faster compared to allowing complete disuse atrophy during the recovery period.
What a session looks like
The dog’s fur must be clipped or parted at the electrode sites — good contact is essential, and hair prevents it. Conductive gel is applied to the skin, then self-adhesive electrode pads are placed over specific motor points (points in the muscle where the nerve triggers contraction).
The device is switched on and intensity gradually increased. At NMES settings, you will see the muscle visibly contract and the limb twitch or move. This looks startling the first time — but when delivered correctly, it is not painful. Most dogs either ignore it or become relaxed.
Typical sessions run 15–20 minutes. Frequency depends on the dog’s presentation — in the acute phase, 3–5x weekly in a clinic is common. Your rehab vet may also loan or prescribe a home NMES unit for more frequent use between sessions.
Device recommendations
Professional clinic units (for reference)
Clinical NMES units cost $1,000–5,000+ and offer precise control over frequency, pulse width, intensity, ramp, and multiple channels. Common systems in veterinary rehab include:
Globus Genesy 600 / 1000 — widely used in veterinary rehabilitation in Europe and increasingly in the US. Multi-channel, covers both TENS and NMES modes, highly programmable. Ask your rehab vet if they use Globus.
Chattanooga Intelect — standard human physical therapy unit commonly adapted for veterinary use. Reliable, multi-mode.
EMS 7500 — affordable clinical unit with good programmability. Under $1,000.
Home use options
Home NMES/TENS units are widely available — but there is a critical caveat: electrode placement matters enormously. Incorrect placement for NMES in a dog recovering from spinal cord injury can be ineffective at best and potentially counterproductive. Have your rehab vet or a rehabilitation therapist demonstrate correct placement on your dog before attempting home use.
That said, once you have been shown correct technique, home NMES between sessions is one of the highest-impact things you can do for a paralyzed or weak dog.
iReliev Wireless TENS + EMS System
~$70–90 | Amazon | Wireless electrodes, 14 modes, rechargeable
Human-grade unit that works well for dogs when electrode placement is correct. Wireless electrodes are a significant practical advantage — no cables to tangle or stress the dog. Covers both TENS (pain) and EMS/NMES (muscle stimulation) modes.

Marc Pro Plus
~$649 | Amazon | marcpro.com | Professional-grade home unit
Originally designed for human athletic recovery and muscle reactivation, the Marc Pro produces strong, comfortable muscle contractions using a waveform designed to avoid the fatigue response that shorter-duration NMES can cause. Premium build quality, used by some integrative vets for home prescriptions. Higher price but genuinely better output than budget units.

HealthmateForever YK15AB
~$35–50 | Amazon | Budget entry point
At the affordable end: a basic TENS/EMS combo unit with multiple modes and reasonable build quality. Not as precise or comfortable as higher-end units, but functional if budget is the primary concern. Good to have on hand once electrode placement has been demonstrated by a professional.

InTENSity Twin Stim III
~$80 | Amazon | Combo TENS + NMES, 3-year warranty
A reliable mid-tier combo unit. Separate channels allow simultaneous treatment of two limb groups. Good choice for owners who want more than a budget unit but aren’t ready to invest in Marc Pro.

Electrode pads for dogs
Standard human electrode pads work for dogs — but sizing matters. For large breed dogs, standard 2″×2″ pads are appropriate for most limb muscles. For smaller dogs or more precise placement (e.g., tibialis anterior), 1.5″×1.5″ or smaller pads are better. Reusable gel pads last 20–30 uses; always store them face-down on their backing sheet.

When NOT to use NMES at home
Do not use NMES:
- Over the spine directly (use laser or PROM for spinal work)
- Near the heart or cardiac devices
- Without prior demonstration by a veterinary rehabilitation professional
- If your dog shows any signs of pain or distress during stimulation
Not medical advice. NMES electrode placement for spinal cord injury rehabilitation should be demonstrated by a certified canine rehabilitation professional before home use. Always consult your rehab vet.
