The correlation between ADL and the roentgenographical findings of the elbow joint was examined in 60 patients with RA involving some of the shoulder, elbow, and wrist joint. Of these patients, thirteen showed no symptoms of the elbow joint and forty-seven some symptoms of this joint.
1) When roentgenographical changes were classified by the method of Larsen, groups B and C presented a high systemic activity.
2) The frequency of involvement in the elbow joint was parallel with that in the wrist joint. The severer the changes of the elbow joint, the higher the frequency of involvement in any other joint.
3) The ROM of the elbow joint was reduced in accordance with the progress in destruction of the joint. The disturbance of the upper limbs in ADL seemed to be closely related to the restriction of pronation and supination.
