Electrical stimulation (often called e-stim or ESTIM) is a commonly used therapeutic tool in physical therapy that helps support pain management, muscle activation, and recovery when used appropriately. It is often integrated into a broader rehabilitation program to help patients move more comfortably and regain function.
At OSI Physical Therapy, electrical stimulation is used selectively and intentionally, guided by licensed physical therapists as part of a personalized treatment plan—not as a stand-alone solution.
What Is Electrical Stimulation in Physical Therapy?
Electrical stimulation involves the application of controlled electrical currents through surface electrodes placed on the skin. These currents interact with nerves or muscles to support specific therapeutic goals, such as pain reduction or muscle activation.
In physical therapy, electrical stimulation may be used to:
- Help activate muscles that are weak or inhibited
- Support early strengthening after injury or surgery
- Reduce pain to allow better participation in therapy
- Improve awareness and control of targeted muscles
Electrical stimulation is always applied and adjusted by a licensed physical therapist based on individual needs and tolerance.
Electrical Stimulation in Physical Therapy
At OSI Physical Therapy, electrical stimulation is guided by licensed physical therapists who understand anatomy, neuromuscular function, and injury patterns. Treatment is tailored to your body to help reduce pain, activate muscles, and support recovery—working with your body, not against it.

How Electrical Stimulation Works
Electrical stimulation delivers gentle electrical pulses that mimic signals normally sent by the nervous system. Depending on the settings and purpose, this may:
- Encourage muscles to contract
- Influence the sensory nerves involved in pain perception
- Improve circulation in targeted tissues
The goal is to support healing and movement—not to replace active rehabilitation.
Common Uses of Electrical Stimulation in Physical Therapy
Electrical stimulation may be incorporated into care for:
- Muscle weakness or inhibition
- Post-surgical rehabilitation
- Acute or chronic musculoskeletal pain
- Joint injuries involving reduced muscle activation
- Conditions where pain limits active movement
Not every patient requires electrical stimulation. Your physical therapist determines whether it is appropriate based on evaluation findings and treatment goals.
Types of Electrical Stimulation Used in Physical Therapy
Physical therapists may use different forms of electrical stimulation depending on the intended outcome.
Neuromuscular Electrical Stimulation (NMES)
NMES is used to stimulate muscle contraction and support muscle activation, particularly when muscles are weak or not firing efficiently.
Transcutaneous Electrical Nerve Stimulation (TENS)
TENS is commonly used for pain modulation by stimulating sensory nerves to reduce pain signals.
Other forms of electrical stimulation may be used selectively in clinical settings based on therapeutic goals. Your therapist will explain the purpose and expected response before treatment.
What Does Electrical Stimulation Feel Like?
Most patients describe electrical stimulation as:
- A light tingling or buzzing sensation
- Gentle rhythmic muscle contractions (with NMES)
Electrical stimulation should not be painful. Intensity levels are always adjusted to ensure comfort and safety.
Benefits of Electrical Stimulation When Used in Therapy
When integrated into a comprehensive treatment plan, electrical stimulation may help:
- Reduce pain and discomfort
- Improve muscle activation and control
- Support early strengthening
- Enhance circulation to targeted tissues
- Improve tolerance to movement and exercise
Electrical stimulation is most effective when combined with hands-on therapy, movement retraining, and guided exercise.
Safety and Clinical Considerations
Electrical stimulation is generally well tolerated, but it may not be appropriate for everyone.
Possible Side Effects
- Mild skin irritation at electrode sites
- Temporary muscle soreness
- Sensitivity to stimulation intensity
These effects are typically mild and resolve quickly.
Who May Not Be a Candidate
Electrical stimulation may not be recommended for individuals with:
- Pacemakers or implanted electrical devices
- Certain neurological or cardiac conditions
- Open wounds or skin irritation at electrode sites
Your physical therapist will review your medical history to ensure safe use.
