TENS / E-stim
Electrical stimulation is a treatment used in physical therapy to support pain relief and recovery for a variety of conditions. It typically uses small, self-adhesive electrodes placed on the skin near the area being treated. These electrodes connect to a unit that delivers a gentle electrical current designed to interact with sensory and/or motor nerves.
At iMotion Physical Therapy, electrical stimulation may be recommended as one part of your personalized plan of care.
What is electrical stimulation used for?
Electrical stimulation may be used to support recovery and function in a variety of situations, including:
- helping reduce pain (acute or chronic)
- decreasing muscle tightness or spasm
- improving tolerance to movement and daily activity
- supporting muscle activation and retraining (when appropriate)
What’s the difference between TENS and NMES?
We may use different types of electrical stimulation depending on the goal of treatment.
TENS (Transcutaneous Electrical Nerve Stimulation)
TENS is most commonly used for pain relief. It works by stimulating sensory nerves to help reduce the sensation of pain and improve comfort during movement.
NMES (Neuromuscular Electrical Stimulation)
NMES is sometimes used to help activate a muscle that is weak or difficult to engage, especially during rehabilitation or after injury.
What does electrical stimulation feel like?
Most patients describe electrical stimulation as a mild sensation, such as:
- tingling
- buzzing
- a light pulsing feeling
When used for muscle activation, the sensation can feel stronger and the muscle may visibly contract. It may be slightly uncomfortable at times, but it should not be painful. Intensity can be adjusted to your comfort level throughout treatment.
What happens during electrical stimulation treatment?
Electrical stimulation is typically performed while you’re seated or lying comfortably, with settings adjusted based on your goals and tolerance.
How will I know if electrical stimulation is helping?
Many patients notice changes such as:
- less pain during activity
- improved tolerance to exercise or therapy
- reduced muscle tightness or spasm
- improved ability to use or activate a muscle during rehab (when NMES is used)
Your response may be immediate, gradual, or vary depending on what is being treated
Is electrical stimulation safe?
Electrical stimulation is generally safe when used appropriately. Before treatment, we screen for contraindications to make sure it is a safe option for you.
Electrical stimulation may not be appropriate for individuals with certain medical conditions or implanted devices. Your provider will review your health history and determine whether electrical stimulation is appropriate for your plan of care.
Electrical stimulation is one part of your plan of care
Electrical stimulation may be used alongside other physical therapy treatments such as:
- hands-on therapy (when appropriate)
- mobility and strengthening exercises
- movement training
- patient education
Electrical stimulation can support recovery, and it works best as part of a complete plan of care.
Frequently Asked Questions
