  • based on suggested frequency of involvement25, feasibility8, orrepresentative value of target joints9, or were developed in alogistic regression model26. Two reduced joint counts seemedto present good validity issues: the 12-joint count proposed byNaredo, et al26 and the 7-joint count by Backhaus, et al25.Joints selected in the proposed 12-joint count are wrist,MCP-2, MCP-3, knee, ankle, and elbow evaluated bilateral-ly26. Examining the other proposed joint counts, we found thatsome of them included a minimal number of 7 joints in theirscoring systems and, in particular, joints featured in the 7-jointcount25 combination [i.e., wrist, MCP-2, MCP-3, PIP-2, PIP-3,metatarsophalangeal (MTP)-2, and MTP-5] were included inthe global synovitis scores of 50% (7 of 14) of the articles. Inorder to evaluate the applicability of the 7-joint count in anoth-er dataset, we analyzed data from Naredo and colleagues byusing the proposed selection of 7 joints from Backhaus25.Comparative results on responsiveness by using the 2 jointcounts are presented in Table 4. The use of the 7-joint count inthe new dataset also showed good responsiveness; however,the application of this joint count bilaterally (14 instead of 7

    joints) was characterized by higher sensitivity to change,which was closer to that observed with the evaluation of all ini-tially evaluated joints (i.e., 44 joints).


    The prospect of developing a global ultrasound joint score isattractive, in that it might potentially be able to more objec-tively reflect the real level of synovitis, and hence diseaseactivity of patients with RA, compared with conventionalclinical measures, i.e., disease activity indices. In order to beaccepted as an objective tool, ultrasound must demonstratereliability and sensitivity to change, and the evaluation of several joints must also appear feasible. This review hasdemonstrated that ultrasound is a worthwhile tool for assess-ing global joint inflammation in RA.

    This review has highlighted that discrepancies were pres-ent among studies, relating to the definition and detection ofsynovitis, and in the composition of joints included in theglobal evaluation of disease activity. The variability of defini-tion and detection of synovitis at joint level within the studies
