Abstract
In this study of polymyalgia rheumatica, no primary abnormality in muscle was found. The muscle pains appeared to be largely referred from central joints, tendons, and ligaments. Giant-cell arteritis was found a high proportion of the patients, and those with and without arteritis had the same manifestations in the loco-motor system. Those with arteritis were usually older, had more constitutional illness, higher erythrocyte sedimentation rates, and raised alpha2 globulins. Synovitis of central joints and arteritis may coexist, and it is suggested that they may be manifestations of a single disease process.
