In Fig. 5, the patient is so seated beside the machine that he can insert one thigh between the pads of the rubber, and also control the lever with the hand. It is sometimes more convenient to suspend a movable weight from the lever. While the machine is running, he can withdraw the leg gradually, as each portion receives its proper amount of action, till the whole, including the foot, becomes glowing with the effect. The boot or shoe affords no impediment to the effect, and should remain on.
Sometimes, especially in the beginning, or when the feet are habitually cold, it is better to apply the action only from the knees down.
The rubbing-pad (d) may be attached to either side of the machine, according to convenience or effect sought. The action derived from the right end of the rock-shaft is much less severe than that from the left, on account of the shape of the rubber appendage, and at the beginning should be used in preference. In Fig. 6, the patient sits on an ordinary stool, or, if feeble, in a chair, and presents any portion of the chest or abdomen to the action of the rubber. The instrument is raised or lowered to suit convenience, while the patient gently presses portions of the trunk successively upon the rubbing-pad. The degree of the effect is thus always under the absolute control of the one receiving the action. This operation, like the preceding, produces great heat, reddens the skin, relieves pain, and greatly stimulates the functions, not only of the skin, but of the organs contained in the cavities of the chest and the abdomen.
The same operation may be applied also to the legs while the patient is standing.
In Fig. 7, the back is presented to the action of the rubbing-pad. The action will, if desired, be made to reach from the neck to the hips, and even to the thighs. All sensitive portions of the back should at first be omitted, in order that they may be benefited by the counter-irritation or drawing away of the blood. This is easily produced by those familiar with the use of the machine. The rubbing of the back should be deferred till the close of each application, in order that the spinal centers may be relieved of hyperæmia, or excess of blood.
The machine, as represented by Fig. 8, is brought to the desired elevation, about as high as the shoulders, and the hand-holder is attached. One arm is extended horizontally, and the hand grasps the hand-holder, while rapid motion is given by turning the wheel. An alternate twisting motion is communicated to the arm, which causes corresponding pressure and relaxation of all the soft tissues of the limb, combined with slight rubbing or attrition. The action is increased by contracting the muscles, and also by grasping at greater distance from the center. Both hands may grasp at the same time, or the two sides may receive the motion in turn. The effect is similar to that of the rubbing before described, but it is less limited; by grasping firmly, it may extend to the whole chest.
