Abstract: The present invention discloses an Adaptive Neural-Biofeedback Orthosis (ANBO), which is a wearable closed-loop electromechanical system configured for predictive suppression of pathological tremors associated with neurological movement disorders including Parkinson’s disease, essential tremor, cerebellar tremor, multiple sclerosis, and post-stroke motor dysfunction. The system comprises a multi-channel electromyography (EMG) acquisition subsystem, an embedded processing unit executing a Predictive-Suppression Algorithm (PSA), a Variable Stiffness Actuator (VSA) subsystem integrated into an orthotic joint mechanism, a biofeedback interface, and an ergonomic wearable orthotic frame. The EMG acquisition subsystem continuously monitors neuromuscular electrical activity from agonist and antagonist muscle groups of an affected limb and transmits the acquired signals to the embedded processor for real-time analysis. The PSA performs signal preprocessing, tremor biomarker extraction, time-frequency analysis, voluntary movement classification, and machine-learning-based tremor prediction to identify tremor-predictive neural signatures prior to overt mechanical limb oscillation. Upon detection of a tremor-predictive state, the PSA generates a Tremor Suppression Command that dynamically controls the VSA subsystem to modulate orthotic joint stiffness and apply proportional counter-impedance forces against impending tremor movement. The VSA subsystem may comprise magnetorheological fluid dampers or antagonistically coupled servo motor actuators capable of rapid adaptive stiffness modulation. A Voluntary Motion Classifier integrated within the PSA distinguishes intentional motor activity from pathological tremor and maintains the orthotic system in a compliant low-stiffness state during voluntary movement, thereby preserving natural motor function and user comfort. The invention further incorporates patient-specific adaptive calibration, wireless clinician monitoring, real-time biofeedback communication, and longitudinal tremor event logging. The present invention therefore provides a non-invasive, intelligent, predictive, and personalized tremor suppression platform capable of selectively attenuating pathological tremor before physical manifestation while maintaining unrestricted voluntary movement, thereby overcoming the limitations of passive orthoses and conventional reactive tremor control systems.
