Summary

Trigeminal neuralgia (TN) is the most common cause of facial pain. Medical treatment is the first therapeutic choice whereas surgery, including Gamma Knife radiosurgery (GKRS), is indicated in case of pharmacological therapy failure. However, about 20% of subjects lack adequate pain relief after surgery. Virtual reality (VR) technology has been explored as a novel tool for reducing pain perception and might be the breakthrough in treatment-resistant cases. The investigators will conduct a prospective randomized comparative study to detect the effectiveness of GKRS aided by VR-training vs GKRS alone in TN patients. In addition, using MRI and artificial intelligence (AI), the investigators will identify pre-treatment abnormalities of central nervous system circuits associated with pain to predict response to treatment. The investigators expect that brain-based biomarkers, with clinical features, will provide key information in the personalization of treatment options and bring a huge impact in the management and understanding of pain in TN.

Interventions

PROCEDURE

GKRS-VR training

One month after radiosurgery, GKRS-VR subjects will receive neuromodulation treatment twice a week (30' per time), for 8 consecutive weeks followed by 9 months of remote rehabilitation. GKRS-VR group will perform neuromodulation based on VR sensorimotor rehabilitation using an immersive system developed ad-hoc. Treatments will include voluntary mimic movements reinforced by VR augmented feedback, consisting in the reflection of a real-time avatar animation, multiplied when needed, associated with different targets to reach based on specific facial gestures. The execution of motion multiplier on avatar will be allowed in order to personalize treatments, emphasizing a graded exposure to pain perception. In addition, the investigators will develop a dedicated mobile-application for remote rehabilitation with the aim of prescribing VR augmented feedback home exercises and immersive VR pain neuromodulation.

PROCEDURE

Control Group

Control Group will undergo only radiosurgery with no rehabilitation and they will perform only clinical evaluation at study entry, after three months and one year.
