Researchers modified the original carpal stretch test and prospectively performed that version on 48 patients with a total of 49 unstable intra-articular distal radial fractures. The average sensitivity of the modified carpal stretch test was 78 percent.
The average specificity of the tests was 72 percent, average predicted value was 60 percent, average negative predictive value was 87 percent and the average accuracy was 74 percent. The intraclass correlation coefficient for interobserver agreement was 0.73.
