From these Considerations I cannot but be induc’d to think, that in all obstinate Pains, caus’d by the irregular Motions of the Spirits, and in the true Hysterick Colick, one of the most frequent of those sort of Pains; it would be more natural, and in no wise absurd, to recommend to the Patient, the Use of a Chaise, or light Calash, even in the Paroxysm it self, than the Fatigue of Medicines; the best of which, except Opiates, so often prove delusive. That Exercise is convenient for Women, with Liberty to sit or lie; and tho’ the Motion at first may seem a little troublesome, and the Shocks too rude; yet I think, upon what I have hinted before, there is great Reason to expect, that after a little Patience the Spirits would be brought to relent, and disengage themselves from the _Plexus’s_, where they occasion so great Pain. I am the more confirm’d in this Opinion, because there is a Pain which seems more deeply rooted, even in the Tendons of the Muscles, _viz._ the Cramp, which will frequently go off, by changing the Posture the Part was in, when it was first seiz’d; and especially by getting out of the Bed, and walking a little while, when no Pressure or Ligature will remove it, unless the Person rise; by which undoubtedly the Spirits are call’d back into some of the superiour Muscles, or some way or other put into a new sort of Motion. This Opinion may be corroborated likewise by what has been experienc’d by some Hysterick People, who when they have lain perhaps half a Night restless and disturb’d, and without the least Inclination to Sleep, upon getting out of their Beds, and walking a turn or two about the Room, shall find themselves quite alter’d, and when they come into the Bed again, sleep well; so that if so sudden and short an Alteration of the Posture of the Body, can produce so good an Effect, much more may be expected from the Exercise I have above mention’d; wherein the sick Person may at once enjoy the Convenience of a Cradle, and the Vehemence of a Exercise. I might pursue this Notion, in considering the _Scorbutick Rheumatism_; in which Case the Persons afflicted are generally strong, and able to undergo any sort of Exercise; and therefore all the sorts of Exercise which I shall hereafter mention, will agree with ’em: But it will be needless to multiply words, that Distemper being chiefly seated in the Nerves, what I have said already will serve to illustrate the Advantage, which Persons griev’d with that Distemper might receive from a resolute and prudent Use of Exercise.
