PURPOSEWe have reported that there are scapulo-humeral rhythms in the horizontal planes with flexion and extention of the shoulder joint as well as with the elevation of arms and decrease in movements of scapulo-thoracic joint by ageing. Now we wish to propose that there also exists a scapulo-humeral rhythm in the rotation of the shoulder.SU BJECTS AND METHODSWe measured the scapular inclination in seven normal volunteers ranged from 23 to 37(mean: 31), using an X-CT and setting it at a neutral position with the shouldes in abduction 0 ° and flexion 0° and the elbow in flexion 90 ° . The scapular inclinations were measured:1)from neutral to 30° and the maximal rotatio nal position (internal and external)2)at neutral and 30 ° rotation (internal and external) when maximal rota tion isotonic motion were performed.
