When using electrical muscle stimulation on a trigger point, what polarity should be used?

• A. Positive polarity
• B. Neutral polarity
• C. Negative polarity
• D. Variable polarity

Answer: (C)

Using electrical muscle stimulation on a trigger point typically involves applying a negative polarity. Trigger points are hyperirritable spots in skeletal muscle that can cause pain and discomfort. The application of negative polarity helps in reducing pain, facilitating muscle relaxation, and promoting healing in the affected area. This is due to the way electrical stimulation interacts with muscle tissue and nerves; negative polarity can assist in attracting positive ions and promoting increased circulation, which is beneficial for alleviating discomfort associated with trigger points. Positive, neutral, and variable polarities may not provide the same therapeutic benefits specifically associated with alleviating the condition of trigger points. Thus, utilizing negative polarity is a targeted approach to maximize the effectiveness of electrical muscle stimulation in this context.
