An operator is seated, scaling the mandibular arch with elbows raised to his or her own shoulder level. Which of the following should be done?

Question

Quizplus · Accepted Answer

The client's chair should be lowered to an operator's waist level to lower the elbows less than 20 degrees from the waist. The operator should adjust the client's chair first to remain seated using a hip hinge and not bend over with a standing position. Raising the client's chair will not improve access and will cause elbows to be raised higher. Raising the shoulder higher will not resolve the problem and contribute to RSI.
