Harnessing the Body’s Own Signals to Promote Healing

Electrical stimulation (e-stim) is a versatile, evidence-based modality used to manage pain, reduce swelling, and restore muscle function. At Healing Star PT, we use electrical stimulation as a targeted complement to manual therapy and therapeutic exercise — helping patients get more out of every treatment session.

How It Works

Electrical stimulation works by delivering controlled, low-level electrical currents through electrode pads placed on the skin near the area of treatment. These currents interact with the body’s nervous system and muscle tissue in ways that promote healing and pain relief.

Depending on the parameters used, e-stim can:

• Block pain signals traveling to the brain (similar to the mechanism behind a TENS unit)
• Stimulate muscle contractions to reduce atrophy, re-educate muscle activation patterns, and rebuild strength
• Reduce edema and inflammation by promoting fluid movement in the tissue
• Improve local blood flow and accelerate tissue healing

Types of Electrical Stimulation We Use

TENS (Transcutaneous Electrical Nerve Stimulation): Primarily used for pain management. TENS works by stimulating sensory nerves to override pain signals before they reach the brain — providing effective, drug-free relief.

NMES (Neuromuscular Electrical Stimulation): Used to stimulate muscle contractions in weakened or inhibited muscles. Particularly valuable after surgery or prolonged immobilization when the brain-muscle connection has been disrupted.

Interferential Current (IFC): A deeper-penetrating form of electrical stimulation often used to manage pain, reduce swelling, and improve circulation in larger or deeper tissue areas.

Who Can Benefit?

Electrical stimulation can be beneficial for patients dealing with:

• Acute and chronic pain
• Post-surgical weakness and muscle inhibition
• Swelling and edema following injury or surgery
• Muscle atrophy from disuse
• Back and neck pain
• Joint pain and inflammation
