Disclosed herein is a technology for automatically calibrating a reference orientation of an implantable medical device (IMD) within a patient. In one example, a sensor of an IMD senses multiple orientation vectors of the IMD relative to a gravitational field. A processing circuit system of the IMD processes the multiple orientation vectors to identify an upright vector corresponding to an upright posture of the patient. The processing circuit system classifies the multiple orientation vectors relative to the upright vector to define a sagittal plane of the patient and a transverse plane of the patient. The processing circuit system determines a reference orientation of the IMD within the patient based on the upright vector, the sagittal plane, and the transverse plane. When the orientation of the IMD within the patient changes over time, the processing circuit system can recalibrate its reference orientation and accurately detect the patient's posture.

This invention discloses a method and device for dynamic blood pressure assessment based on postural transition phases. It identifies postural transitions from postural sensor data and delineates the boundaries of the preparation, transition, and stabilization phases based on individualized reflex delay compensation. It constructs an individualized blood pressure baseline curve based on phased sampling and establishes a phased reference benchmark. It detects a continuous downward trend in the blood pressure deviation sequence and applies individualized rate constraints to form a dynamic trajectory. It removes physiological periodic components using an adaptive rhythm template and determines abnormal fluctuation ranges and completes phased risk assessment based on a joint score of non-rhythmic fluctuation amplitude and duration. It integrates the risk assessment results with the individual baseline level for adaptive weighting based on postural orientation, determines differentiated warning thresholds, and outputs blood pressure change assessment results. This achieves individualized and phased-differentiated accurate assessment of blood pressure abnormalities induced by postural transitions, improving the accuracy and adaptability of orthostatic hypotension risk assessment.

This application provides a method and system for gait and cognitive training adjustment for patients with cerebral small vessel disease. The method superimposes a preset cognitive task during the patient's normal walking process, simultaneously collecting gait and cognitive data under dual-task conditions to obtain dual-task data. Based on gait baseline data, cognitive baseline data, and dual-task data, a dual-task interference index is calculated. Postural control training is then performed on the patient using a balance training device.
