A randomized controlled educational study to evaluate an e-learning module to teach the physical examination of the temporomandibular joint in juvenile idiopathic arthritis.

BACKGROUND

The aim of the study was to evaluate the effectiveness of a novel e-learning module in teaching the physical exam of the temporomandibular joint (TMJ) in Juvenile idiopathic arthritis (JIA.).

METHODS

An e-learning module was developed to convey the TMJ physical examination maneuvers that are considered to be best practice in JIA. Pediatric rheumatology fellows were randomized to two groups. One group received an article describing the physical examination skills while the second group received both the article and module. All participants completed a written pre-test, an in-person objective structured clinical examination (OSCE), a written post-test, and a follow-up survey.

RESULTS

Twenty-two pediatric rheumatology fellows enrolled, with 11 per group. Written test: The two groups improved equally, although there was a trend toward improved defining of maximal incisal opening (MIO) in the module group. OSCE: The mean OSCE score was 11.1 (SD 3.3) in the article group and 13.5 (SD 1.9) in the module group (p = 0.06); significant differences were seen in measuring MIO (p = 0.01), calculating maximal unassisted mouth opening (MUMO; p = 0.01), and assessment of facial symmetry (p = 0.03), all favoring the module. Enjoyment scores in the module group were higher than in the article group (mean 7.7/10 vs. 5.9/10, p = 0.02). The two groups self-reported performing TMJ examinations at comparable rates three months following the intervention.

CONCLUSIONS

The study demonstrated that a formalized educational program improved knowledge of the physical exam of the TMJ in JIA. Learners viewing the module were more adept at obtaining quantitative TMJ measurements.
