Aim: The objective of this study was to evaluate whether musculoskeletal (MS) ultrasound (US) can be useful in helping medical students to detect joint inflammation through physical examination. Material and methods: The study was performed by two groups of four 6 th year medical students. None had received any previous training in the clinical examination of joints or the use of ultrasound. Students were put through a 5-session training programme on the clinical detection of either knee [group 1] or metacarpophalangeal (MCP) [group 2] inflammation. After an initial training session on physical examination of normal and inflamed joints, the students examined 170 joints from 41 patients attending the hospital outpatient clinic in 4 separate sessions. The same joints were assessed for synovitis with US with the ensuing data compared to that of the students and analyzed for concordance with Cohen's unweighted kappa. Results: In total 60 knees [group 1] and 110 MCP [group 2] were evaluated. The agreement between the presence of arthritis detected by the students in the four sessions and the presence of synovitis detected by US improved from the session I to sessions III with a marked improvement in the last session. Conclusions: MSUS may be an effective technique for helping students to acquire the ability to detect joint inflammation.
