Mechanical device for monitoring joint motion and providing audio-haptic feedback

This device detects joint motion between the neck and shoulder using a deflectable metal beam attached with adhesive pads. It provides audio and haptic feedback upon deflection, promoting user independence and eliminating the need for constant supervision.

Background

Monitoring joint movement, particularly in therapeutic settings, presents several challenges with existing methods. Traditional approaches often involve patients performing exercises under the supervision of a clinician or in front of a mirror to correct improper movements, such as “shoulder hiking.” This process is time-consuming, requiring extensive observation and intervention from healthcare professionals, which can limit patient independence and the efficient use of clinical resources. Moreover, current solutions often lack the ability to provide real-time feedback to patients, hindering their ability to self-correct and practice independently.

While some devices aim to address these issues, they frequently rely on complex electronics, making them costly and less accessible. Also, these devices may not be user-friendly or adaptable to different joints and movement types, limiting their applicability and ease of use in various therapeutic contexts.

Technology description

This technology is a device designed to detect joint motion, specifically between the neck and shoulder, using a deflectable beam. The beam is attached to the user with adhesive pads and is typically made of metal with a curved profile. It provides both audio and haptic feedback when it deflects due to joint movement.

The device features support at each end of the beam, which are connected to the adhesive pads. As the joint moves, the distance between the pads changes, causing the beam to deflect. This deflection triggers an audible noise and a change in the beam’s stiffness, offering feedback to the user. The beam's dimensions, such as length, width, and thickness, can be adjusted for various applications, and the device is designed to be user-friendly, inexpensive, and easy to attach and remove.

This technology stands out due to its purely mechanical nature, eliminating the need for expensive or complex electronics. It provides real-time feedback through audio and haptic signals, allowing users to independently monitor and adjust their joint movements. This independence is particularly beneficial in therapeutic settings, where patients can self-correct without constant supervision. The device’s simplicity and adaptability make it suitable for a wide range of applications, from clinical therapy to personal use. Its mechanical feedback system ensures reliability and ease of use, promoting efficient and effective joint movement monitoring.
