In patients in the first stage of ataxia the most striking result of incoördination is the impairment of station. We therefore begin with balancing lessons. The patient is directed to stand at "Attention," head up and chest out, not looking at his feet, as the ataxic always wishes to do. At first this is enough to require; it will not do to be too particular about how his feet are placed, so long as he does not straddle. He can repeat this effort for himself a dozen times a day, for a minute or two each time. Next we try the same position with a little more care about getting the feet pretty near together and parallel, or with the toes turned out only a very little. In another couple of days a little more severity may be exercised about maintaining the correct attitude,--heels touching, hands hanging down, and eyes looking straight forward,--and until he is able to do this _easily_ it is best to ask nothing more. Then he is requested to stand on one foot, being permitted just to touch a chair-back or the attendant's hand to give confidence. This is practised until he can keep his erect station for a few seconds without difficulty. This point of improvement may be reached in three days or a week or may take a fortnight. Women, as I have before observed, although rarely in America the victims of tabes, when they do have it have far less disturbance of balance than men, and this is to be attributed to their life-long habit of walking without seeing their feet. I have found in the few cases of ataxia in women that I have seen that they benefited much more quickly by these balance instructions than did men, though their other symptoms were in no way different. Continuing every day the practice of all the previous lessons, movements are rapidly added as soon as station is better. A brief list of them follows. When the exercises grow so numerous as to take overmuch time, the simpler early ones may be omitted. When the learner is able to stand on one foot, let him slowly raise the other and put it on a marked spot on the edge of a chair. This, like all the other exercises, must be practised with both feet. Stand erect without bending forward and put one foot straight back as far as possible. Do the same sideways. Stand and bend body slowly forward, backward, and sideways, with a moment's rest after each motion.
