Electrolysis in Physiotherapy: An Innovation in the Treatment of Musculoskeletal Injuries
Percutaneous electrolysis has become an advanced and effective technique in the field of physiotherapy, especially for treating chronic injuries. Within this approach, EPI (Percutaneous Intratissue Electrolysis) stands out as an innovative method transforming the way healthcare professionals address the rehabilitation of damaged soft tissues.
This article will explore in depth the EPI treatment, its applications, benefits, contraindications, and how it can be an essential tool for physiotherapy clinics and rehabilitation centers.
What does Percutaneous Intratisular Electrolysis consist of?
EPI is a minimally invasive technique that uses galvanic current applied through an intratissue needle. This procedure causes controlled inflammation that stimulates regeneration of the affected tissue. Therapeutic percutaneous electrolysis is ideal for treating chronic tendinopathies, plantar fasciitis, muscle injuries and more. Although we will delve more into this topic later.

The Great Relevance of the EPI Technique in the Medical Field
The EPI method is recognized in physiotherapy for its precision and efficacy in tissue regeneration. Unlike other treatments, this EPI technique acts directly on the injured tissue, accelerating the healing process.
This technique has proven to be particularly effective in the treatment of tendinopathies and muscle injuries, positioning itself as a key tool for clinics seeking to offer advanced solutions.
According to several physiotherapists with experience in the treatment of tendinopathies, this technique has proven to be differential in the improvement of chronic pain, accelerating the rehabilitation of affected tissues. All clinics and medical centers that adopted this technique reported higher patient satisfaction and better results in relatively short periods of time. Hence its relevance.
Advantages of Percutaneous Electrolysis in Physiotherapy Practice
Implementing intratissue percutaneous electrolysis in a clinic can set it apart from competitors by offering advanced therapeutic treatments that improve patient outcomes. Additionally, using EPI enables physiotherapists to treat complex cases more effectively, increasing patient satisfaction and, in turn, the clinic’s reputation. Key advantages include:
- Pain reduction: Helps alleviate both chronic and acute pain from various musculoskeletal injuries.
- Tissue regeneration stimulation: Speeds up the recovery of damaged tendons and muscles.
- Chronic injury treatment: Effective for tendinitis, plantar fasciitis, and other persistent conditions.
- Mobility improvement: Helps restore function and flexibility in affected joints.
- Minimally invasive: No surgery or significant side effects are involved.
What PPE resources and materials are indispensable in a health center?
To offer effective percutaneous electrolysis treatments, healthcare centers must have the right materials and resources. Additionally, ensuring that staff are trained in its use and protocols is crucial to guarantee treatment safety and efficacy for patients.

- Function: The main component of the EPI treatment, through which the galvanic current is applied to the affected tissue (e.g., tendon or muscle).
- Characteristics: The needle should be stainless steel, sterilized, and appropriately sized for the area being treated.
Galvanic Current Generator (APSe4)
- Function: This APSe4 device supplies the continuous galvanic current necessary to induce electrochemical effects in the damaged tissue.
- Characteristics: Allows the current’s intensity to be regulated based on the needs of the treatment and type of injury.
Reference Electrode (or Ground Electrode)
- Function: Placed on a different part of the body to close the electrical circuit and allow the current to flow properly.
- Function: Although the EPI treatment is minimally invasive, the use of disposable gloves and protective equipment is crucial to maintain hygiene and prevent cross-contamination.
- Characteristics: Gloves should be latex or a similar material to ensure safety for both the patient and the physiotherapist.
Areas of Application: Where is EPI Used Most Frequently?
There is a wide range of musculoskeletal disorders that can be treated with percutaneous electrolysis. Its primary application is in both chronic and acute conditions affecting tendons, ligaments, and muscles.
Some of the most common conditions treated with EPI include tendinitis, plantar fasciitis, and generalized muscle pain. Its ability to stimulate tissue regeneration and reduce pain makes it a relevant and popular therapeutic option in physiotherapy clinics.
Highlighted Treatments:
- Shoulder: Used for rotator cuff injuries, tendinitis, and other painful conditions in the shoulder joint.
- Elbow: Ideal for treating epicondylitis (tennis elbow), reducing inflammation and pain in the tendons.
- Wrist: Used for wrist tendinitis or tendon injuries associated with repetitive movements.
- Knee: Treatment for patellar tendinitis and other knee-related injuries, such as patellofemoral pain.
- Achilles Tendon: Effective for treating Achilles tendinopathy and fasciitis, promoting tendon regeneration.
- Heel: Used for plantar fasciitis, helping to relieve heel pain and improve mobility.

How to inform patients about the contraindications of EPI without losing their trust
Although electrolysis therapy offers multiple benefits, it is essential to understand its contraindications. These include patients with pacemakers, pregnant women, or individuals with local infections in the treatment area.
It is crucial for clinics to perform a thorough evaluation before proceeding with the treatment.
Cases that require special caution:
- Pain hypersensitivity: The technique may be painful, so it is important to evaluate each case individually.
- Pacemakers or implanted electronic devices: The electrical current could interfere with the functioning of these devices.
- Infections in the treatment area: Active infections, open wounds, or severe inflammatory processes should prevent the application.
- Coagulopathies or anticoagulant treatments: The use of anticoagulants may increase the risk of bruising or bleeding during the procedure.
- Pregnancy: While there is no conclusive evidence regarding risks, it is usually avoided as a precaution.
- Allergic reactions to materials: Hypersensitivity to the needle material or any component used.
- Weakened general health: In cases of severe systemic diseases, the patient’s ability to recover may be compromised.
- Uncontrolled epilepsy: Electrical stimulation could trigger seizures.
Clearly explain that EPI is a safe and effective treatment when performed under the right conditions, and that evaluating contraindications is a responsible measure to protect the patient’s well-being and ensure the best possible results.
How to manage common patient concerns about EPI: “Does the treatment hurt?”
One of the most common concerns among patients is whether the treatment is painful. While there may be some slight discomfort during the procedure, the pain is minimal and temporary.
Most patients report significant improvement in chronic pain after just a few sessions, which outweighs any initial discomfort.
Final Thoughts
Percutaneous electrolysis, particularly the EPI treatment, is revolutionizing the field of physiotherapy. Clinics and professionals adopting this innovative technique will be better equipped to offer effective solutions to their patients, increasing retention and attracting new clients.
Don’t forget to always have dry needling Electrotherapy in your clinic for the EPI treatment. They are essential for properly applying the galvanic current and ensuring effective tissue regeneration
Understanding its applications, benefits, and contraindications, the EPI method in physiotherapy represents a strategic investment for any business in the healthcare sector.
