RESUMEN
A search of the literature in this area shows that there is little national or international documentation available on the effect of physical activity on the development of disease in inflammatory rheumatic disorders. Low capacity for physical work has been demonstrated and is based on poor circulation and reduced muscle strength in rheumatism: several studies from Norway and elsewhere have documented the value of physical training, especially in improving the rheumatic patient's physical condition (1--2, 8). No investigations have been able to document any arrest of progress of the disease, but physical training seems to be able to maintain existing joint function and also to some extent prevent progressive deterioration in condition. There is therefore no disagreement about the significance of physiotherapy, but the intensity and duration of training are more controversial.
