Assessment of joint inflammation at the wrist of patients with rheumatoid arthritis: thermography findings closely mirror those from ultrasonography
Authors' conclusion
Thermography at the wrist appears promising in RA with its findings closely mirroring those from ultrasonography. Swollen joints (regardless of tenderness status) have higher joint surface temperatures and greater ultrasound-detected joint inflammation, findings which were not observed for tender only (non-swollen) joints.
Study context
- Population
- Right wrist of patients with RA
- Participants
- 70 wrist joints
- Exposure
- Thermography vs US for detecting joint inflammation at the RA wrist, across four clinical wrist groups
- Outcome
- Thermographic (the maximum (Tmax), Tavg, Tmin) and US (Total PD (TPD), Total GS (TGS)) parameters across wrist groups
Methodological detailsone-way ANOVA and Kruskal-Wallis test with post-hoc tests
- One-way ANOVA and Kruskal-Wallis test with post-hoc tests
Main finding
As reported in the abstract
- Significant differences between the 4 wrist groups for all imaging parameters (ANOVA or Kruskal-Wallis)
- all p<0.05
Observational data: associations, not effects.
