Clinical Validation

Rigorous science, real-time mental state estimation, and a calculated pathway to clinical integration.

Efficacy of Neurofeedback

A Validated Modality

Decades of peer-reviewed research demonstrate that neurofeedback is a highly effective intervention. Clinical guidelines increasingly recognize it as a robust, non-pharmacological treatment option that induces neuroplastic changes in the brain, leading to sustained, long-term improvements in attention and impulse control.

Why VR Integration Matters

Therapeutic efficacy relies fundamentally on patient engagement. Traditional 2D screen therapies suffer from low engagement and high dropout. By shifting the biofeedback loop into an immersive virtual reality (VR) environment, Attune drastically increases patient focus, adherence, and satisfaction, accelerating robust clinical outcomes.
In addition, VR enables multi-sensor integration beyond EEG. For example, the inclusion of inertial movement sensors (IMUs) enables far greater artifact rejection and accuracy in estimates.
