Galvanic Stimulation

Galvanic Stimulation, also known as galvanic current or direct current (DC) stimulation, is a type of electrical stimulation therapy that uses direct electrical currents to stimulate nerves, muscles, and tissues for various therapeutic purposes. Unlike some other electrical stimulation modalities, such as TENS or IFC (Interferential Current), which use alternating current (AC), galvanic stimulation utilizes a constant, unidirectional current.

Mechanism of Action:

1. Galvanic Stimulation delivers a constant flow of electrical current, typically through electrodes placed on the skin over the treatment area.

2. This unidirectional current can be used to create two primary effects:

   1. Polarization of Tissues: The continuous flow of electrical current causes the positive ions to move towards the negative electrode (cathode) and the negative ions to move towards the positive electrode (anode). This polarization effect can affect the properties of tissues and may help with pain relief and inflammation reduction.

   2. Iontophoresis: Galvanic stimulation can be used for iontophoresis, a process that facilitates the transdermal delivery of medications, such as anti-inflammatory drugs, by using the electric current to drive the medication through the skin and into the underlying tissues.

Applications:​

1. Pain Management: It may be used to alleviate pain, especially for conditions like chronic pain, musculoskeletal pain, and nerve pain.

2. Inflammation Reduction: Galvanic stimulation may help reduce inflammation in tissues, making it useful for conditions like bursitis or acute injuries.

3. Wound Healing: It has applications in wound care by promoting tissue healing and reducing the risk of infection.

4. Muscle Contraction and Rehabilitation: In some cases, galvanic stimulation can be used for muscle strengthening and rehabilitation, especially in cases of denervated muscles

Galvanic Stimulation Device:

1. A galvanic stimulation device consists of a control unit and leads with electrodes.

2. Electrodes are placed on the skin over the area to be treated. There is typically one anode (positive electrode) and one cathode (negative electrode).

3. The control unit allows for adjustments in intensity, duration, and treatment settings.

Procedure:

1. The therapists determines the appropriate placement of electrodes and configures the galvanic stimulation device based on the patient's condition and objectives.

2. The patient typically undergoes galvanic stimulation therapy sessions, during which they may experience a mild tingling or prickling sensation in the treatment area.

3. The treatment duration and intensity are adjusted to meet the patient's needs.

 

Safety and Precautions:

1. Galvanic Stimulation is generally considered safe when administered correctly, with proper electrode placement and adherence to recommended settings.

2. Safety precautions should be taken to prevent skin irritation or discomfort, and individuals with certain medical conditions may have specific contraindications or require special considerations.

 

Effectiveness:
The effectiveness of galvanic stimulation varies depending on the specific condition and therapeutic goals. It can provide pain relief, reduce inflammation, and support healing in a variety of clinical scenarios.

Galvanic Stimulation is a versatile modality in the realm of electrical stimulation therapy. It can be valuable in rehabilitation, pain management, and wound care, but it is most effective when administered by trained physiotherapists and occupational therapists at CARe who can tailor the treatment to the individual's needs and monitor the therapeutic progress. If you are considering galvanic stimulation therapy, consult with our therapists at CARe to determine its suitability for your specific condition and to receive guidance on its use.
