[How to manage occupational cramp].
The article deals with some diagnostic traits of local dystonia (dyscoordination neurosis) in musicians, which is caused by occupational strain. Unsatisfactory biomechanics of the musicians fingers and hands appeared to be negative effects, the special role in occupational crasp formation was proved for imperfect flexibility of the hands. Other risk factors could be overload of the hands, resulting from higher motivation for success and improvement, false position of the hands and consequent static strain of the participating muscles, trauma to the hands. Occupational crasp and local dystonia are considered to differ from hysteria manifestations in musicians. Some recommendations are given for musicians and their teachers to prevent possible occupational crasp and local dystonia.
