The subject of occupation in connection with T.B., is not only an extremely important one but an extremely difficult one to administer, particularly in the large government institution, and especially in connection with the psychology of the ex-service man, which has been referred to a number of times. He is apt to misunderstand and to be resentful toward any application of work; and yet at the same time, if we are going to measure the results of the sanitarium treatment of T.B. by the functional restoration to activity and usefulness, we still find that it results in a great many failures. That has been one of the complaints on the part of T.B. workers not only in government but in civil institutions as well. We still find relapses occurring after the patient has been discharged from the sanitarium or T.B. hospital. Men go into training, and in a short time undergo another course of treatment, and so on. The reason for that is that they have not been given the necessary physical rehabilitation while still in the sanitarium, while under institutional protection and medical supervision. The question of occupation is so broad that it is impossible to take it up extensively here today. We can point out one or two of the basic principles in connection with its application in the treatment of T.B. One very important feature brought out this morning is the psychotherapeutic object,—the point of view of relaxation or recreation, that is, giving the man something to occupy his mind and improve his morale, helping him to forget his home anxieties and anxiety about compensation. The second point, or 2 A, deals with muscular reconstruction,—conversion of recently acquired adipose tissue into working force by rebuilding flabby muscular tissue which has resulted from the long period of rest. 2 A is the acquiring of a tolerance for T.B, toxins. This is important. We do know that in the recently toxic stage, exercise or work does produce a reaction which is shown by a rise in pulse rate. We know that if exercise is begun in small doses and gradually increased, the time will come when the patient can be made to take a fairly large amount of exercise continuing over a fairly long period of time, without manifesting the symptoms of reaction. Formerly we gave Tuberculin in gradual doses until we reached the point where the man could take an injection which surely would have killed him at the beginning of the course. The main point is if a man leaves the sanitarium before he reaches this toxin tolerance, he is more likely to break down. This is the reason for the man’s frequently returning to the sanitarium for treatment.
