Condition

Musculoskeletal disorders in dentists

Intervention

1. The participants’ task was to perform scaling on upper right maxillary 2nd and 1st molars for 15 minutes
2. Participants in the experiment group received feedback on those data after finishing scaling on the 2nd molar (Feedback), while those who were in the control group received no-feedback data (No-feedback)
3. Participants were randomly assigned into a two-by-two crossover trial using a computer-generated randomization schedule to each of two sequences of working
4. Group A was assigned to an initial testing session receiving the system feedback followed by receiving no feedback in a second testing session
5. Group B was assigned to an initial testing session receiving no feedback followed by receiving the system feedback in a second testing session
