title: [Our modification of ergograph for studying muscle fatigability in myasthenia].
abstract: The authors designed and made an ergograph of own modification and elaborated normal values of fatiguability half-time on the basis of 51 healthy subjects comparing the results with those in a group of 41 myasthenics subjected to thymectomy. The fatiguability half-time was determined in groups of muscles in the hand, axilla and popliteal area and masseters before and 14 days after thymectomy. The ergographic record was obtained without application of drugs as well as at the peak of activity of drugs and at the peak of activity of those after 5 mg Tensilon dose. The investigation made it possible to determine the muscle power before and after tymectomy. The Tensioln test at the peak activity of drugs permitted to establish the necessary dose of anticholinesterase drugs, especially after the operation.
