1. Indications

The procedure of transcutaneous magnetic stimulation is indicated for the management of chronic pain conditions, particularly those arising from traumatic injuries. It is specifically utilized when there is a need to target peripheral nerves that are associated with pain, especially in cases where the pain is localized to the trauma site or near a palpable neuroma.

• Chronic Pain Management This procedure is performed to alleviate chronic pain that persists following a traumatic injury.
• Identification of Painful Nerves It is indicated when there is a need to identify and treat specific peripheral nerves that are contributing to the patient's pain.

2. Procedure

The procedure involves several key steps to ensure effective treatment of the targeted nerve. Initially, the clinician identifies the location of the nerve pain, which may be at the site of trauma or adjacent to a palpable neuroma. This identification is crucial for the subsequent steps of the procedure.

• Step 1: Identification of Pain Location The clinician begins by assessing the patient's pain and determining the specific area where the pain is most pronounced. This may involve palpation and patient feedback to locate the nerve associated with the pain.
• Step 2: Mapping the Treatment Location Once the general area is identified, the clinician uses a coil head of the stimulator device to move along the area while applying low-frequency electromagnetic impulses. The goal is to pinpoint the exact location of the nerve that is causing pain.
• Step 3: Patient Feedback and Adjustment As the coil head is moved, the patient is asked to provide feedback on the sensation experienced. When the patient indicates that the precise point of pain is being stimulated, the clinician incrementally adjusts the amplitude of the impulse to enhance stimulation at that specific site.
• Step 4: Marking the Treatment Site Once the optimal stimulation point is identified, the clinician marks the location on the skin with permanent ink. This marking is essential for future reference and subsequent treatments.
• Step 5: Documentation A photograph is taken to document the position of the coil head in relation to the marked treatment site. This serves as a visual reference for future sessions.
• Step 6: Application of Electromagnetic Pulses The clinician then applies the electromagnetic pulses to the identified painful nerve for a duration of approximately 15 to 20 minutes, providing the therapeutic effect aimed at pain relief.

3. Post-Procedure

After the procedure, patients may experience immediate relief from pain, although the full effects may take time to manifest. It is important for patients to follow any post-procedure care instructions provided by the clinician. This may include recommendations for follow-up treatments, monitoring of pain levels, and any necessary adjustments to the treatment plan based on the patient's response. The clinician may also schedule additional sessions as needed, particularly if multiple nerves require treatment, ensuring that each treated nerve is properly documented and marked for future reference.
