Nexstim is a market leader company in navigated Transcranial Magnetic Stimulation. This is a non-invasive technology used for therapeutic or diagnostic purposes.
Navigated Brain Therapy (NBT) improves the rehabilitation of stroke patients. Navigation is performed by the visualization of the electric field generated by a coil in a 3D MRI image.
Calculation of stimulation intensity is based on the brain excitability and a motor threshold of the individual patient.
Navigated Brain Stimulation (NBS) is the first and only FDA cleared and CE marked nTMS method for preoperatíve neurosurgical mapping of the motor and speech cortices. Electric field of the direct cortical stimulation (DCS) is superimposed on the MRI dataset of the patient. Placing electrodes on the skin above the desired muscles, amplitudes and latencies of motor evoked potentials (MEPs) can be recorded by an EMG. Moving the TMS coil over the patient’s head the electric field location, strength and direction is visible in real-time and creates a map of a cortical somatotopy in the 3D reconstruction of MRI dataset..
