• CuTouch is an innovative somatosensory training system aimed at improving diminished discriminative cutaneous sensitivity in the fingertips. The system employs a multimodal approach with visual, audio, and tactile cues, integrating neuroplasticity and spasticity therapy techniques to enhance attention and subsequently sensory perception. The system consists of two core components: the App and the Station. The mobile application facilitates cutaneous stimulation sessions, conducts user testing, and monitors progress. It activates specific points and patterns, simulates textures, and synchronizes vibrotactile feedback with music note onsets and frequencies. The app’s discrimination testing module is inspired by established two-point discrimination and tactile discrimination tests, enabling standardized, remote assessments with consistent pressure. The Station, a specialized hardware device, delivers precise vibrotactile stimulation, offering a comprehensive at-home training solution. Future research will explore expanding the system’s capabilities and applications to confirm its effectiveness and broader impact further.
