The modified pen grip has been developed to provide human dental
hygienists with a grip that provides good control of the blade whilst
preventing fatigue during long procedures.
the Modified Pen Grip (8 seconds, no audio)
Long term, it should protect against "Carpal Tunnel Syndrome"
(CTS), which is an occupational hazard for those occupations that
work with close control of hand instruments.
Hold the instrument between the thumb and index finger, then bring
the other fingers down so that the shaft lies on the second finger
and under the index finger. The normal pen grip is not recommended
due to reduced control and, potentially, the development of CTS.
