CTS-Guard: a wearable smart device for prevention of carpal tunnel syndrome

Abstract

Carpal Tunnel Syndrome (CTS) is a common repetitive strain injury caused by prolonged wrist deviation from nonneutral positions [1] and pressure on the median nerve. Individuals affected by CTS often experience numbness, tingling, pain, and reduced dexterity in their hands and fingers, which can significantly impact productivity in daily tasks and professional activities. In severe cases, the condition may require surgical intervention. Early detection of risky wrist postures - before permanent nerve damage occurs – is therefore crucial to prevent the onset or progression of CTS. This paper presents CTS-Guard, a wearable that tracks wrist and finger posture, detects prolonged wrist positions, and provides real-time alerts. Unlike existing solutions focused on rehabilitation, CTS-Guard emphasizes prevention and ease of use.
