Electromyography (EMG) is a diagnostic procedure used to assess the health of muscles and the nerve cells controlling them (motor neurons). It involves recording the electrical activity produced by muscles during contraction and at rest. Here are key points about electromyography: 1. **Purpose:** EMG is used to evaluate muscle and nerve function. It helps diagnose conditions such as muscle disorders, nerve disorders, and neuromuscular junction disorders. 2. **Procedure:** During EMG, a small, thin needle electrode is inserted into the muscle being tested. The electrical activity detected by the electrode is displayed on an oscilloscope or recorded for analysis. 3. **Types of EMG:**  - **Surface EMG:** Electrodes are placed on the skin over the muscles.  - **Needle EMG:** Involves inserting a needle electrode directly into the muscle tissue. 4. **Muscle Activity:** EMG provides information about the electrical activity of muscles, including the timing and pattern of...
