AKINESIA ALGERA

Arch NeurPsych. 1933;30(4):843-847. doi:10.1001/archneurpsyc.1933.02240160155008
Abstract

Akinesia algera was described and named by Möbius in 1891.1 He spoke of it as the loss of voluntary motion because of pain produced by motion, and considered that it lacks an organic basis. It occurs in patients of a neurotic type, the déséquilibrés or the mentally maladjusted. At first only the more intense movements produce pain leading to paralysis, but later all or almost all movements cause pain. The pain may occur simultaneously with or after the movements, and may occur not only in parts of the body which have been moved but may extend to other parts which have not been moved. Finally, almost complete immobility may result, simulating general paralysis. Signs of a psychoneurosis may be found, namely, hypochondriasis, hysteria, neurasthenia, etc. Möbius described two cases. He expressed the strongest conviction that he was dealing with a functional disturbance only, and spoke of hallucinations of pain.
