Plain English summary of protocol
Background and study aims:
Work related musculoskeletal disorders (WMSD) have become increasingly common among dentists during the past decades. Repetitive movements and prolonged awkward postures of neck and upper back have been identified as major risk factors for WMSD. Generally, dentists do not have any guidance to assist them with correct neck and upper back positions and movements. No previous study has shown what kind of solution the dentists could employ for monitoring their own neck and upper back movements to help them self correct the extreme posture and movements in order to minimize the risk of acquiring WMSD. There is a need for a reliable and valid observational instrument that can be used to document and assess risk factors for musculoskeletal disorders. This study aims to create an electronic instrumentation for predicting WMSD among dentists, and to evaluate the system performance in assisting dentists with correct neck and upper back positions and movements.
Who can participate?
Dentists aged between 25 to 30
What does the study involve?
Participants are randomly allocated to one of two groups that determined their schedule of working. The participants are tasked to perform scaling on a upper right maxillary 2nd and 1st molars for 15 minutes. Those in the first group received feedback data after the scaling before a second testing session. Those in the second group did not receive any feedback data before a second testing session.
What are the possible benefits and risks of participating?
There are no notable benefits or risks with participating.
Where is the study run from?
Thammasat University Faculty of Dentistry (Thailand)
When is study starting and how long is it expected to run for?
March 2011 to June 2011
Who is funding the study?
Thailand Research Fund (Thailand)

| Scientific title | An electronic instrumentation for predicting musculoskeletal disorders among dentists: a randomised controlled trial |
| Study objectives | Trial to to compare the effectiveness of using an electronic instrumentation for predicting musculoskeletal disorders over the routine dental work. The dentists that received feedback from an electronic instrumentation for predicting musculoskeletal disorders, will decrease the extensions of neck and upper back |

| Health condition(s) or problem(s) studied | 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 |
| Intervention type | Other |
| Primary outcome measure | 1. The angle at 10th percentile of Headx, Heady, Backx and Backy 2. Recorded two times: after finishing scaling on the 2nd molar (Pre-test) and finishing scaling on the 1st molar (Post-test) |
| Secondary outcome measures | The log likelihood for classifying the movements as Work-Related Musculoskeletal Disorder (WMSD) likelihood |
