HeadX Duo is the instrumented evolution of the HeadX system, combining the established head-mounted crosshair laser with integrated multi-axis inertial sensing to support objective assessment, rehabilitation, and performance monitoring of head and neck control. Built on the same visual feedback principles that underpin HeadX Kross, HeadX Duo adds the ability to measure and record movement in real time. This enables clinicians, practitioners, and performance specialists to retain the simplicity and immediacy of laser-guided training, while accessing quantitative data to support deeper analysis, documentation, and progression tracking. Visual precision, enhanced with data At the core of HeadX Duo is the familiar crosshair laser, providing intuitive visual feedback for cervical proprioception, gaze control, and sensorimotor training. This remains central to session delivery, ensuring continuity with established HeadX exercise programmes and clinical workflows. Alongside this, the integrated inertial measurement unit captures head movement across multiple axes, enabling objective metrics such as range of motion, movement velocity, control, repeatability, and symmetry to be recorded during live use. Data collection occurs passively in the background, without disrupting the exercise experience. Designed for clinical and performance environments HeadX Duo connects via Bluetooth to dedicated iOS and Android applications, allowing real-time visualisation of movement data during sessions. This supports guided assessment, structured rehabilitation, and performance monitoring at the point of care. For advanced use cases, captured data can be streamed or exported for offline analysis, longitudinal tracking, research, or reporting. All data is stored locally on the host device, ensuring practitioners retain full control over their information. A complementary choice within the HeadX system HeadX Duo is designed to sit alongside HeadX Kross, not replace it. While HeadX Kross remains an effective and accessible solution for laser-guided training and rehabilitation, HeadX Duo offers an additional layer of measurement for users who require objective data to support decision making, research, or high-performance applications. This modular approach allows clinics, teams, and organisations to adopt the level of capability that best fits their needs, from visual feedback alone through to fully instrumented assessment and monitoring. Key features Head-mounted crosshair laser for intuitive visual feedback Integrated multi-axis inertial sensing for objective movement capture Real-time data visualisation via iOS and Android applications Local data storage with export options for analysis and reporting Seamless compatibility with existing HeadX exercises and workflows HeadX Duo extends the HeadX system with objective insight, while preserving the simplicity, clarity, and clinical focus that define HeadX.
