Electricity will often be found an important adjuvant in this as well as in an earlier stage, not only in improving the nutrition of the muscles, but in promoting absorption, allaying pain, and subduing excitability of the peripheral structures, removing muscular contractions, and probably modifying the local inflammatory processes. It appears also in some cases to improve the general health. The constant current is generally the most useful, and should have an intensity of about ten to fifteen milliampères, and be applied daily for ten or fifteen minutes. The positive pole, terminating in a large flat moistened sponge, is applied to the spinal origin of the brachial or lumbar plexus, according as the superior or inferior members suffer, while the negative pole is immersed in a vessel of warm salt water in which the hands or feet are placed. Some apply the negative electrode to the joints and the positive to the limb higher up.[264] The faradic current may also be employed on account of its action upon the muscles and small vessels. In the advanced stage attended with marked thickening of the articular and periarticular tissues, with contractions of the muscles and greater or less impairment of movement, the above measures are still our chief resources; but they may be employed more vigorously. We have little fear now of lighting up inflammation; we indeed desire to excite a more active circulation in the part with a view of removing the congested state of the capillaries and venules, so favorable to the development of fibroid growths. In this stage especially vigorous active and passive movements of the affected joints, and massage of the muscles which move them, and gymnastics, are imperatively needed, and it is sometimes almost marvellous what an amount of mobility and usefulness may thereby be restored to apparently helplessly crippled and deformed articulations and members. Persons who have not walked for years are frequently so much improved as to be able to leave their sofa or bed, and with or without crutches or mechanical aids walk about, while their abiding pains depart, and this notwithstanding the permanent deformity of the articular surfaces. (For the various mechanical appliances that are sometimes necessary in this advanced stage works upon surgery may be consulted.) [Footnote 264: Homolle, _lib. cit._, p. 710.]
