Sharp instruments are essential to the elimination of fatigue and stress on the clinician's hand, wrist, arm, and shoulders, which cause repetitive stress injuries (RSIs). Dull instruments that deviate from their original design cause the clinician to apply additional force, resulting in increased lateral pressure, excess stroke repetitions, and a tightened grasp.

Question

Quizplus · Accepted Answer

Sharp instruments minimize the amount of lateral pressure used by the clinician, the tightness of the grasp, and the number of working strokes needed. Dull instruments that deviate from their original design will ultimately promote unsound ergonomic motions by the clinician during treatment.
