[Work capacity of patients with neurasthenia].

Clinical and experimental examination of 127 patients suffering from neurasthenia, performed during three stages of the disease development (hyperasthenic, irritative weakness, hypoasthenic++), enabled one to identify an appreciable decrease of a number of the parameters of tolerance to isometric exercise. Thus, force decreased 1.3--2-fold, endurance 2.4--3.4-fold, and work fitness 3.8--6.8-fold as compared to normal persons. Isometric exercise tolerance that increases progressively by the hyposthenic disease stage can be instrumental as an objective diagnostic criterion for evaluation of work fitness during carrying out the rehabilitation measures in neurasthenic patients.
