Any of a group of inherited chronic muscle
disorders marked by weakening and wasting of
muscle. Muscle fibres degenerate, to be
replaced by fatty tissue, although the nerve
supply remains unimpaired. The commonest
form, Duchenne muscular dystrophy, strikes
boys, usually before the age of four. The
child develops a waddling gait and an inward
curvature (lordosis) of the lumbar spine. The
muscles affected by dystrophy and the rate of
progress vary. There is no cure, but physical
treatments can minimize disability.
