With a ordinary goniometer, we measured the range of active motion of the wrist flexion, extension, ulnar and radial deviation in 120 normal adult subjects ranging in age from 20 to 49 years old. Normal limits were determined for the male and female groups, for the age groups, and for the right and left sides, respectively. The data were compared with the axial angles in roentgenograms that described by T.E. Keats in 1966. And we have undertaken a study of the correlation between the range of motion and the axial angles. The results were as following: 1. Range of active motion (degrees±standard deviation) Rexion; 73.9±6.386. extension; 65.9 ±5.164 unlar deviation; 28.3 ±5.124 radial deviation; 18.6±2.556 2. Axial angles (degrees±standard deviation) P-A view;73.8±3.985 lateral view;79.7±4.777 3. Males had a smaller range of motion than female in wrist joint. 4. The right side showed a smaller range of motion than the left. 5. There were no correlations between the range of motion and the axial angles.
