=Stroking.=—This procedure may be given with two or three fingers or the palmar surface of one or both hands. The movement should be gentle, and the contact made as lightly as possible. Stroking should be done always in one direction, and, as a rule, in the direction of the blood currents in the arteries. The physiologic effects when properly applied should be sedative, as the purpose should be to diminish the blood-supply to the part. It produces a certain effect upon the cutaneous nerves which is very quieting. It is often found useful when applied about the forehead for sleeplessness. Nervous headache may be relieved by the same procedure. Neuralgic pains and the vague, but nevertheless uncomfortable, sensations complained of by neurasthenic patients are often relieved by this measure. =Friction.=—In this procedure the whole or part of the palmar surface of the hand is moved over the surface of the body with considerable pressure. The principal effect of friction is upon the superficial blood-vessels and the lymphatics. In the lower extremities the movement should be from below upward in the direction of the venous flow. The same may be said of the upper extremities. The thumb may be made to follow the course of the larger veins, in this manner stimulating the venous circulation. Some patients object to friction applied by the dry hand, in which case some lubricant may be used; pure vaselin, cocoa-butter, and talcum powder are among the best for this purpose. Friction should always be used in the beginning of massage, especially if the surface of the body is cold. It is not the intention here to give minute instruction as to the methods of procedure with all the different parts of the body; only general instructions can be here given, and those requiring further information should consult text-books upon this subject. _Physiologic Effects of Friction._—First, reflex effects upon the vasomotor nerves producing dilatation of the peripheral blood-vessels with increased circulation, aiding the venous and lymphatic circulation. It is useful in all conditions accompanied by poor peripheral circulation. It not only stimulates the circulation, but aids materially in elimination and increased nutrition. It aids in the relief of general dropsy and hastens the absorption of inflammatory exudates resulting from sprains and various joint affections, etc.
