Its inclusion in the undergraduate clerking reper- toire could improve junior doctors' awareness and recognition of rheumatic disease and general disability. It could also provide a valuable screening test for use in general practice.

This requirement is likely to increase as the proportion of elderly patients in the community expands, and as patient percep- tions alter with respect to treatment and health care availability. on October 2, 2021 by guest.

A screening procedure to detect problems in defined areas is therefore desir- able.8 If the screen is positive then targeted regional examination is undertaken to define the problem.
