Does continuous passive motion during keyboarding affect hand blood flow and wrist function? A prospective case report.

The purpose of this prospective case report was to evaluate the use of a keyboard platform device that uses continuous passive motion (CPM) on vascular flow to the hand for clerical employees who perform daily keyboarding tasks. Subjects were two female volunteers, one symptomatic of carpal tunnel syndrome (CTS), who were employed in clerical positions and perform daily keyboarding tasks for most of their workday. Data collection consisted of baseline and follow-up measurements at 6 weeks, including: 1) screening for symptoms based on the Carpal Tunnel Function Disability Form, 2) evaluation using standard physical therapy examination and assessment techniques, including modified Semmes- Weinstein monofilament testing, 3) a typing productivity test, and 4) Doppler ultrasound examination to quantify vascular flow at the wrist.

Interpretive biomicroscopy.

Slit lamp biomicroscopy provides invaluable diagnostic information as to the nature of ocular abnormalities and disease processes. As such, the emphasis to be presented in this discourse is biomicroscopic interpretation, as opposed to simple observation, with each major ocular structure discussed in turn.

Essentials of slit lamp biomicroscopy.

Biomicroscopy is an indispensable part of the ocular health examination performed on every patient. The purpose of this paper is to briefly review the basic illumination technique so that the examiner thoroughly understands their uses and develops for himself a specific investigative procedure. This testing may progress from the lids and lashes to the anterior vitreous in a coordinated manner.
