Effect of a Wrist Motion Storage Biofeedback System (WMSBS) on Wrist Motion during Keyboard Typing Work

Abstract

Abstract.[Purpose] The purpose of this study was to examine the effect of a wrist motion storage biofeedback system on wrist range of motion during keyboard typing work.[Subjects] For this study, we recruited 10 computer workers as volunteers.[Methods] Wrist flexion, extension, ulnar deviation, and radial deviation angles were analyzed using a 3-D motion analysis system. [Results] The wrist flexion, extension, ulnar deviation, and radial deviation angles decreased significantly in keyboard typing work with the wrist motion storage biofeedback system. [Conclusion] We suggest that the wrist motion storage biofeedback system promotes the adoption of a beneficial wrist posture, which may be effective at preventing computer work-related wrist disorders, such as carpal tunnel syndrome.

Effect of the difficulty level of a biofeedback device for postural correction on the orbicularis oculi and upper trapezius muscle activity and trunk flexion angle during computer work

“…Recently, many studies have suggested the use of therapeutic or exercise tools with biofeedback, which provides additional information about users by detecting subtle changes in the body with sensors 1 , 2 , 3 ) . Many therapists give visual and auditory feedback, even during clinical trials 4 ) .…”

“…In particular, there is active research being conducted on the development of a biofeedback tool for people who work at a computer for long hours while sitting in a bad posture 1 , 2 , 3 ) . Researchers have been boosting the sensor capacity of biofeedback tools in order to improve the effectiveness of posture exercises and other exercises 1 , 2 , 3 ) . Such improvement in the tools offers quick feedback of subtle changes in the body 4 ) .…”

“…In particular, visual and auditory feedbacks are often used in clinical trials. Biofeedback tools with greater sensitivity are under development, and those tools will offer a greater amount of feedback at a greater frequency 1 , 2 , 3 ) . However, too much information can trigger stress for patients.…”

Effect of the release exercise and exercise position in a patient with carpal tunnel syndrome

“…Surgical treatment for CTS involves opening the carpal tunnel at the wrist. Currently, there are several non-surgical treatments for CTS, including non-steroidal anti-inflammatory drugs, injection of various medications, immobilization by splinting, rehabilitation modalities, and biofeedback devices 5 , 6 ) . While drugs, injections, and splinting relieve the symptoms of CTS, the long-term outcomes are poor 1 ) .…”
