Dear friend,
John Z Wu, Ph.D., National Institute for Occupational Safety and Health,
Morgantown, WV, USA, will be giving a free webcast presentation on Thursday
May 22nd:
Simulating the dynamic muscle force in an index finger during tapping.
Since musculoskeletal disorders of the upper extremities are believed to be
associated with repetitive excessive muscle force production in the hands,
understanding the time-dependent muscle forces during key tapping will help
to explore the mechanisms of disease initiation and development. In the
current study, we analyzed the dynamic muscle forces in an index finger
during typing using a universal finger model developed on a platform of
AnyBody. Seven muscles were included in the proposed model: flexor digitorum
profundus (FP), flexor digitorum superficials (FS), extensor indicis (EI),
extensor digitorum communis (EC), radial interosseous (RI), ulnar
interosseous (UI), and lumbrical (LU). The time histories of impact force at
the fingertip in the published studies are applied to drive the model. Our
analysis indicates that the power generated by FP, EC, and EI muscles are
predominant among all muscles, while the power generated in MCP joint is
predominant among all three joints. The predicted time-histories of muscle
forces agree well with the EMG measurements in the literature. Our results
suggested that the muscle force is mainly induced by the impact force at the
fingertip during tapping, rather than due to the mass moment inertia of the
finger section.
To accommodate viewers from different sides of the planet we are running the
presentation twice with 12 hours interval:
First show: Thursday May 22nd 07:00AM EDT (New York) - 1PM Berlin - 7PM
Beijing.
Second show: Thursday May 22nd 07:00PM EDT (New York) - 4PM San Francisco -
9AM Friday Sydney - 11AM Friday Auckland.
The duration of the webcast is approximately one hour including Q&A. The
event is free but it is necessary to sign up to participate. Please do it
