Electroanalgesia
Electroanalgesia is a form of pain management that uses electric current to relieve pain. It is a type of electrotherapy specifically used for pain relief in various medical conditions and post-surgical recovery.
Mechanism of Action[edit | edit source]
The mechanism of action of electroanalgesia involves the application of electrical stimulation to the skin or tissues, which interferes with the transmission of pain signals in the nerves. This is based on the gate control theory of pain, which suggests that non-painful input closes the "gates" to painful input, preventing pain sensation from traveling to the central nervous system.
Types of Electroanalgesia[edit | edit source]
There are several types of electroanalgesia, including:
- Transcutaneous Electrical Nerve Stimulation (TENS): This is the most common form of electroanalgesia. It involves the use of a small, battery-operated device that delivers low-voltage electrical currents through the skin via electrodes.
- Percutaneous Electrical Nerve Stimulation (PENS): This involves the insertion of thin needle electrodes in the skin near the area of pain. The electrodes deliver electrical currents that stimulate the nerves.
- Spinal Cord Stimulation (SCS): This involves the placement of a small device in the body that sends electrical currents to the spinal cord to control pain.
Uses[edit | edit source]
Electroanalgesia is used to manage pain in a variety of conditions, including chronic pain, neuropathic pain, arthritis, fibromyalgia, and migraine. It is also used in post-surgical pain management and in physical therapy for muscle pain relief.
Risks and Side Effects[edit | edit source]
While electroanalgesia is generally safe, it may cause some side effects such as skin irritation at the site of electrode placement. It is not recommended for individuals with pacemakers or other implanted electronic devices, or for those with certain heart conditions.
