(20) This is a similar movement by the opposite thigh. If desired, additional movements of flexion, extension, androtation of the hands and feet may be devised. In carrying outthese exercises care should be taken that movements involvingthe use of the same groups of muscles do not succeed each otherdirectly, but are interrupted by exercises made by different setsof muscles. The purpose of this precaution is the avoidance ofundue muscular fatigue of weak patients. Given with requisitedeliberation, and with sufficient pauses for rest between move-ments, such a series of resistance gymnastics ordinarily takes about. 4G4 DISEASES OF THE HEART half an hour. If after a rest of ten to fifteen minutes the patientdoes not feel or evince fatigue, he may then repeat the are generally given daily, an hour or more after a whose condition is fairly good may be allowed to per-form them twice a day—that is, in the forenoon and again in theafternoon. These exceedingly simple exercises are a powerful agent forgood or a means of great harm, depending on the manner in whichthey are given and the condition of the heart. I do not believethey should be given to patients whose compensation is whollygone. In this opinion I differ, I think, with Schott and BezlyThorne, who have written so much in praise of them.
