=Muscular Tone.= A force that affects circulation, blood pressure, respiration, nutrition of cells, secretion, and digestion, can hardly fail to have a marked effect on the tone of the muscles, internal as well as external. When we remember that heart, stomach, and intestines are made of muscular tissue, to say nothing of the skeletal muscles, we begin to realize how important is muscular tone for bodily health. Over and over again have I demonstrated that a courageous mind is the best tonic. Perhaps an example from my "flat-footed" patients will be to the point. One woman, the young mother of a family, came to me for a nervous trouble. Besides this, she had suffered for seven or eight years from severe pains in her feet and had been compelled to wear specially made shoes prescribed by a Chicago orthopedist. The shoes, however, did not seem to lessen the pain. After an ordinary day's occupation, she could not even walk across the floor at dinner-time. A walk of two blocks would incapacitate her for many days. She was convinced that her feet could never be cured and came to me only on account of nervous trouble. On the day of her arrival she flung herself down on the couch, saying that she would like to go away from everybody, where the children would never bother her again. She was sure nobody loved her and she wanted to die. Within three weeks, in ordinary shoes, this woman tramped nine miles up Mount Wilson and the next day tramped down again. Her attitude had changed from that of irritable fretfulness to one of buoyant joy, and with the moral change had come new strength in the muscles. The death of her husband has since made it necessary for her to support the family, and she is now on her feet from eight to fourteen hours a day, a constant source of inspiration to all about her, and no more weary than the average person. Flabbiness in the muscles often causes this trouble with the feet. "The arches of the foot are maintained by ligaments between the bones, supported by muscle tendons which prevent undue stretching of the ligaments and are a protection against flat-foot."[31] Muscle tissue has an abundant blood supply, while ligaments have very little and soon lose their resiliency if unsupported. Any lack of tone in the calf-muscles throws the weight on the less resistant ligaments and on the cartilages placed as cushions between the bony structures of the arch. This is what causes the pain.[32] [Footnote 31: Grey's Anatomy--"The Articulations."] [Footnote 32: Actual loss of the arch by downward displacement of the bones cannot be overcome by restoring muscle-tone. The majority of so-called cases of flatfoot are, however, in the stage amenable to psychic measures.]
