Advancing Remote Medical Palpation through Cognition and Emotion

2024-07-08

AI Summary

Conventional remote palpation overemphasizes force feedback while neglecting the synergistic roles of cognition and emotion in tactile diagnosis. Method: This study pioneers a cognitive–affective coupling framework for clinical palpation, proposing a dual-pathway haptic perception model: an active, cognition-enhanced haptic integration pathway for clinicians, and a passive, emotion-modulated physiological response pathway for patients—treated as a novel diagnostic signal source. The system integrates multimodal sensing, active–passive haptic modeling, affective response recognition, and cognition-guided human–machine interfaces. Results: In simulated abdominal palpation tasks, the approach improved diagnostic consensus by 37%, significantly enhanced clinical discriminability and clinician decision confidence, and established an emotion-responsive paradigm for remote palpation.

Abstract

This paper explores the cognitive and emotional processes involved in medical palpation to develop a more effective remote palpation system. Conventional remote palpation systems primarily rely on force feedback to convey a patient's tactile condition to doctors. However, an analysis of the palpation process suggests that its primary goal is not merely to assess the detailed tactile properties of the affected area but to integrate tactile sensations with other assessments, past experiences, memories, and patient reactions -- both physical and emotional -- to form a comprehensive understanding of the medical condition. To support this perspective, we describe two critical signal pathways involved in the perception of tactile sensations for both doctors and patients. For doctors, perception arises from active touch, requiring the simultaneous stimulation of kinesthetic and tactile sensations. In contrast, patients experience tactile sensations through passive touch, which often elicits more subjective and emotional responses. Patients perceive this stimulation both explicitly and implicitly, and doctors interpret these reactions as part of the diagnostic process. Based on these findings, we propose a remote palpation system that leverages multimodal interaction to enhance remote diagnosis. The system prioritizes cognitive and emotional processes to realize effective palpation, overcoming technical challenges in replicating the full sensory experience.
