RENEWED interest in ophthalmodynamometry during recent years has revealed difficulties in the actual technique which may be attributable, at least in part, to the dynamometer in common use, designed by Bailliart (1917). Many of these troubles have their origin in the lack of control over the instrument that is so frequently experienced. This is especially common when the operator is in the earl...

OBJECTIVE To develop and determine the reliability of a newly -designed resistance-enhanced dynamometer for muscle strength measurement, and to test the hypothesis that enhancing the examiner's resisting force improves the reliability of manual muscle strength measurements. DESIGN An intra-examiner, inter-examiner, intra-session and inter-session reliability study. SUBJECTS Twenty-five men ...
