Navigated transcranial magnetic stimulation (nTMS) is a sophisticated, non-invasive technique utilized to map motor function in both the upper and lower extremities. This procedure is particularly important in the context of therapeutic treatment planning or surgical interventions. The process involves the application of transcranial magnetic stimulation (TMS), which generates electrical activity in the brain's cortex, subsequently leading to a response in the peripheral nerves. By integrating magnetic resonance imaging (MRI) with TMS, clinicians can achieve real-time, three-dimensional visualization of the induced electric field, enhancing the precision of the mapping process. This advanced mapping technique is crucial for surgeons as it provides a detailed framework that helps minimize the risks associated with procedures performed near the motor cortex, such as paralysis or functional impairment. Consequently, nTMS facilitates more effective surgical outcomes, allowing for the complete resection of tumors or the targeted removal of areas responsible for epileptic triggers while safeguarding the patient's motor function.

The procedure of motor function mapping using navigated transcranial magnetic stimulation (nTMS) is indicated for various clinical scenarios where precise mapping of motor function is essential. The following conditions and situations warrant the use of nTMS:
The procedure of motor function mapping using nTMS involves several critical steps that ensure accurate mapping of motor functions. Each step is designed to maximize the effectiveness of the procedure while ensuring patient safety.
After the completion of the nTMS procedure, patients are typically monitored for any immediate adverse effects, although the non-invasive nature of the technique generally results in minimal side effects. Patients may resume normal activities shortly after the procedure, as there is no significant recovery time required. However, it is essential for healthcare providers to review the mapping results with the patient and discuss any further steps in their treatment or surgical planning. Continuous follow-up may be necessary to assess the effectiveness of the therapeutic strategies developed based on the nTMS mapping results.
