Wounded: Recurrent stammering: Reëducation.
Case 582. (MacMahon, August, 1917.)
A young English officer, previously cured of stammering while a boy, fell to stammering again after being twice wounded. The impediment was of the laryngeal type. When spoken to he was often quite speechless. In Shell-shock stammering, the chief difficulty according to MacMahon is in the production of voice consonants and vowel sounds. In mild cases the trouble is best left alone.
This officer was anxious to pass into the regular army from the reserve to which he was attached. The stammering prevented this. He was treated nine months and improved rapidly. He passed through the trying ordeal of the medical board successfully and went to his regiment.
In severe cases the patient is taught how to fill his lungs properly. He is taught to acquire an inferior lateral costal expansion in inspiration. During expiration the abdominal muscles are trained to contract slowly and strongly, pressing the diaphragm upwards and drawing the lower ribs downwards and inwards. This steady breathing produces a sensation of repose in the stammerer. He is not to raise the upper chest and not to tense the throat, tongue or jaws.
The main vowel sounds are now taught. The main vowel sounds are oo, oh, au, ah, a and ee. They combine in six ways, oh and oo in the word wound, ah and ee make the long i, au and ee in boy, oh and oo in road, a and ee in rain and fair, ee and oo in new and you. There are also words in which no main vowel or compound sounds appear, which may be placed either on the open ah position or the closed ee position. Such words as long, abbot, among, which are on the position of ah and such words as it, sister, minister which are in the position of ee. The voice consonants are b, d, g, j, l, m, n, r, v, w, y, z, w being oo sound and y the ee sound. The breathed consonants are c, f, h, k, p, q, s, t.
The treatment of stammering intensified by Shell-shock is more difficult than that of Shell-shock stammering de novo.
