_Treatment of Acute Symptoms_.--For acute symptoms, the coal tar products may be used and usually afford distinct relief. They include all the old-fashioned salicylates as well as certain more recent compounds, such as aspirin. Phenacetin, however, though usually not thought of in this connection, is an excellent remedy for the discomfort. These drugs should be used freely so as to give relief from the painful condition. The fact that they afford relief, however, should not be taken as an argument that the condition is rheumatic.
Rheumatism, as we know it, is an acute infectious disease and there is no reason in the world for saying that the salicylates or cognate drugs are specifics in this affection. They relieve the pain, but just in the same way they would relieve the pain of toothache or of any other painful condition. After the acute symptoms are removed, the condition that remains may be treated in various ways, by ma.s.sage, by local applications, and by such manipulations as will restore the normal circulation of the part. Care must be taken, however, to distract the patient"s mind from the local condition after a time, or mental influence, by interfering with the capillary circulation, may inveterate the symptoms. It is not good to keep patients at rest, though rest, of course, is always indicated if there is much discomfort. Sometimes, however, the discomfort is really due to the fact that muscles have not been used for some time and so are easily fatigued and may ache even under ordinary use. In this case, a gradual restoration of the muscles to normal strength by progressively increased exercise is important.
_Counter-Irritation and Its Suggestive Value_.--Personally, I have found the use of turpentine particularly efficacious in connection with suggestion. The old-fashioned system of ironing seems to do more good than any ordinary application of turpentine. For this a piece of flannel wrung out in warm water has some turpentine scattered over it and then is placed on the affected loins or back of the thigh and covered by another piece of flannel, and a hot flat-iron is rubbed over it. The physical effect is a considerable hyperemia, but the effect upon the patient"s mind is especially interesting, the unusualness of the mode of application adding decidedly to the effect.
It must not be forgotten, however, that there are some people who are over-susceptible to the influence of turpentine, and its use is followed by a rash.
_Lumbar and Sciatic Psychoneuroses_.--Many cases of lumbago and sciatica are really psychoneuroses. They develop exactly as psychoneurotic conditions do in the abdomen or in joints. Not infrequently there is some accident or injury, some sprain or strain, or exposure to dampness or draft, that serves as the occasion. The Germans group all these occasions together under the word "insult."
The "insult" produces little physical effect but after some days or sometimes weeks, the slight discomfort present secures the center of {407} attention and then the patient suffers from what seems to be severe pain and often inability to move or use muscles. Even when there is true sciatica or lumbago, that is, a genuine low-grade neuritis of the lumbar or sciatic nerves, most of the symptoms may come from the a.s.sociated psychoneurosis. This is proved to be so by the fact that such patients are often cured, for the time being at least, by some shock or fright or sudden excitement, that makes them move, forgetful of the pain and inability from which they suffered just before. Besides, such cases are often cured by inert remedies of many kinds, by local applications that have no specific effect, and by various methods of treatment which cannot be responsible for the recovery. The amelioration of the condition is due to the mental influence accompanying the methods of treatment and the rea.s.surance of the patient"s mind.
_Diversion of Attention_.--Almost anything that produces a continuous succession of sensations on the surface of the affected area that attract and hold the attention of the patient may prove a valuable therapeutic suggestion and even eventual relief from symptoms that have proved obstinate to more rational treatment. Liebault, the well-known founder of the Nancy school of hypnotic therapeutics, tells in his "Therapeutique Suggestive," that he has frequently cured lumbago by the simple recommendation of a rather stiff piece of paper to be applied over the patient"s loins. The rationale of this treatment seems to be that the patient"s attention is attracted to the skin surface by the sensations constantly produced by it and attention is distracted from other feelings deeper in the muscles. It often happens that after an acute lumbago has run its course, there is left a chronic achiness only partly physical and largely psychoneurotic.
Some of it is undoubtedly due to the habit, formed during the acute period, of keeping the muscles quiet, in order to avoid the spasmodic pain that occurs on movement. Patients cannot, as it were, let go of their muscles, and their discomfort is largely due to holding them in a cramped position. The sensation produced by the paper on the cutaneous nerves distracts the attention and brings about relaxation of the muscles with decrease of discomfort and gradual relief of all symptoms.
The paper acts as a constant source of suggestion for the cure of the psychoneuroses when the affection is purely psychoneurotic. The mind has become concentrated on the idea of pain and discomfort in this region and needs another thought to occupy itself with so as to neutralize this. Wearing the paper with the a.s.surance, for instance, that because of its impermeability to air it keeps the part more thoroughly protected from variations of temperature and from such possibilities of transudation as have before been possible, serves to lift patients out of themselves and affords relief. Whenever the sensation produced by the paper is noted, there is a renewal of the suggestion and its curative effects. There are many plasters that have obtained the reputation for curing lumbago. It is doubtful whether any of these have sufficient medicaments on them to be of any serious pharmaceutic significance. They are mostly rubber plaster. The presence of this and the consciousness of the sensation produced by it acts as favorably as does Liebault"s sheet of paper.
_Mechanical Agents_.--It must not be forgotten, however, that a large sheet of adhesive plaster firmly applied may act as a mechanical therapeutic agent, somewhat in the same way that strips of adhesive plaster relieve the pain of pleurisy, or are helpful in a sprained ankle or a knee. The muscles may be {408} held rather firmly together and so there is no necessity for constant attention to prevent spasmodic pain. Undoubtedly some of the newer large-sized adhesive plasters produce an excellent effect in this way. If, besides, the patient has the feeling that they must be doing him good because of materials in their composition, the psychoneurotic elements are more readily relieved. The old idea was that such plasters drew out the pathological elements to the surface whence they were dissipated.
There is no truth underlying this thought.
In the old days blisters were applied rather freely to these regions and the actual cautery was often employed. Both of these therapeutic processes are likely to do good in chronic cases, but much more from their psychic than their physical effects. The actual cautery is not used nearly so much as it ought to be in chronic muscular and neurotic conditions, for the mental effect of its application and the distraction of attention to the skin surface while the cauterized areas are healing are excellent remedies.
There are other counter-irritant procedures of the same kind that have been used with reported successes in many cases. Hot needles, for instance, if pushed deeply into the muscles, often have an excellent effect. Some years ago a distinguished surgeon insisted that both lumbago and sciatica might be cured in many cases by the insertion of needles deeply into the muscles. He argued that what happened was that these needles brought about an equilibrium of electricity in the muscular structures which had somehow been disturbed. Deep injections of water into the muscles also do good. Stretching of nerves has been applied with reported success. After a time all of these measures fail, however, because somehow after the novelty of the treatment wears off for the physician, the patient"s mind is not sufficiently impressed and then the former results are not secured. Where there are actual neuritic processes present they will almost surely fail. So many of these cases are almost pure psychoneuroses, however, that it is little wonder that anything which produces a strong impression on the mind and leaves after it some condition that attracts attention and so furnishes favorable suggestion will almost surely cure even chronic conditions for which all sorts of physical remedies, employed on rational grounds, have failed.
Anything that modifies the circulation, even to a slight degree, or by causing a reaction in the local vaso-motor state, alters previous conditions, tends to enable the patient to control the affected part.
These psychoneurotic conditions in large muscles help us to understand what happens in organic diseases. There is a physical element that must be modified, but unless a strong influence is brought to bear upon the mind so as to arouse all its capacity for control, the cure will not come. Anyone of a dozen things, however, may be used in this way and often when one fails another will succeed. In obstinate cases of lumbago and sciatica if necessary a number of these forms of treatment should be used successively.
_Hypnotism_.--How much pure psychotherapy may mean for many of these obstinate cases of lumbago and sciatica can be appreciated from the many reports of cures by hypnotism or by suggestion in a light hypnoidal state, or occasionally, under favorable circ.u.mstances, even in the waking state. One of these cases, indeed, is responsible to some extent for the French interest in hypnotism which attracted so much attention in the last quarter of the {409} nineteenth century.
Prof. Bernheim of the University of Nancy had seen a case of sciatica in which every therapeutic means at his command had failed. As the result of disuse the leg was emaciated and possessed little muscular power. It looked as though the man would never be able to regain the use of it properly. Dr. Liebault succeeded in curing the patient by light hypnotic sleep, in which the suggestion that he would be better was given while the physician stroked the limb. After the first seance the patient was able to use the leg better and the discomfort was greatly decreased. Further seances with Dr. Liebault brought further improvement until finally the condition was cured. Prof. Bernheim, who knew how intractable these cases are, had the case called particularly to his attention and naturally wanted to learn more about the method by which it had been brought about. Liebault"s methods had been quite contemned by the regular faculty before. After a series of experiences under Dr. Liebault"s direction Prof. Bernheim became enthusiastic over the use of hypnotism as a curative agent and this led to the publication of his well-known work "De la Suggestion et ses Applications dans la Therapeutique." [Footnote 34] It was the interest aroused at Nancy that led Charcot to take up hypnotism, and while he came to very different conclusions, there is no doubt that the work at Nancy meant much for our knowledge of suggestion in both waking and hypnotic state in therapeutics.

CHAPTER VII
PAINFUL KNEE CONDITIONS
Most of the painful knee conditions of which patients complain are not directly due to true pathological conditions either of the knee joint itself or of its neighboring structures, but rather to affections of other portions of the leg that set a special strain upon the knee and, above all, to various kinds of foot disturbances. The erect position is maintained princ.i.p.ally by a nice balance of nervous and muscular energy in the knee joint and its surrounding structures. Any irregular sensory or motor impulses to the knee-joint or to the muscles of the thigh will disturb the absolute equilibrium of the flexors and extensors and will make standing painful or even impossible. Whenever a morbid condition requires a different use of the muscles and tendons around the knee from that to which they are accustomed, fatigue readily ensues, and aches and even tenderness in muscles and tendons develop as the result of the over-exertion. These collateral conditions must not be overlooked in the diagnosis and treatment of painful knee conditions.
Etiological Factors.--Even a slight sore on one foot will give rise to considerable achy fatigue of the knee of the opposite leg, because, consciously or unconsciously, we stand much more on that leg, use it more in walking, and spare the other because of the pain induced by use of the foot. Above all, throwing more weight on the other leg causes us to use muscles a little abnormally with consequent soreness.
This painful fatigue is most likely to be felt around the knee, though it may extend to the hip and even the lumbar {410} region of the well side if the foot continues to be spared for a number of days.
Particularly will this be true if there is anything the matter with the big toe, on which so much of the use of the foot depends. An ingrowing toenail will not infrequently give so much discomfort to the well knee and hip as to make the patient sure that there must be some rheumatic or other condition at work in these joints. The serious affection of the joint which the patient apprehends is found to be no more than a sympathetic fatigue induced by having to use his feet, or one of them, a little differently from usual, perhaps because of some condition that leads him to spare them. To call the patient"s attention to this is of itself therapeutic.
_Inequality of Legs_.--The effort required for standing and the accurate balance of the muscles involved in it is such that any mechanical disturbance of the feet or legs or even a trivial pathological condition causes painful fatigue. It must not be forgotten, for instance, that the presumption that human limbs are of exactly the same length is not confirmed by accurate measurements.
There is an average difference of probably half an inch in length between the limbs of normal persons, and there may be even a difference of more than an inch before deformity is said to be present. The longer limbs are likely to do more work and are, therefore, more subject to fatigue and consequent complaint. One of the reasons why we can distinguish persons by their gait even at a distance is that the difference in the length of their limbs makes noteworthy characteristics in their walk.
_High Heels_.--People who are used to walking in a natural manner and who don a pair of high-heeled shoes for the first time are sure to complain of pain in the calf and knee, because the high heels require them to hold the knee more rigid and in a somewhat different position from that required when the persons stand under ordinary circ.u.mstances. It is the unusual in muscular effort that gives rise to the extreme fatigue which becomes positive pain if it is allowed to continue. It is curious how small a raising of the heel will cause discomfort. Over and over again I have known the careless putting on of rubber heels to be responsible for pains around the knee, which in damp weather were the source of so much discomfort that it was hard to persuade the patient that he was not suffering from rheumatism or some serious incipient pathological condition.
_Unusual Occupations_.--Joint pains often develop after the patient has been doing something quite unusual and putting an unaccustomed strain upon his muscles. I have often seen dispensary patients whose knee pains began after there had been a family moving. In the course of the removal of household goods, both men and women are likely to help in hanging pictures, in taking them down, in moving heavy furniture and other occupations of this kind which make them extremely tired. If there is any tendency to relaxation of joint structures the tiredness may manifest itself as a sense of painful discomfort. The knees are particularly likely to suffer if there is a relaxed condition anywhere in the leg. It must be remembered that the laxity of tissue which predisposes a patient to weak or flat feet will have a tendency to produce some looseness of fiber, at least, also in the tissues around the knee. The patient may not have a wabbling knee, nor may he be able to overextend the limb, but still there will usually be some noticeable relaxation of the tissues which will help in the production of the painful condition by {411} making exaggerated calls upon the muscles in order to keep the joint in proper position in spite of the over motion in it.
The disturbance is most frequent in waiters, store clerks, tailors"
cutters and fitters, bench men in the trades, and in all those who have to spend much time on their feet. I have seen many such ready to give up their occupations, though they had no other resource and the future looked very blank, indeed, away from their work. It was difficult at first to persuade them that a slight yielding of the arch had so changed mechanical conditions in the use of the muscles of the leg as to produce such pains. But as soon as they were put in a condition where their arch was not allowed to sink, they were at once relieved of their discomfort to a great extent. The question of treatment is discussed more fully in the chapter which follows on Foot Troubles.
An interesting set of painful conditions around the knee develops in a cla.s.s of people in whom it might least be suspected of being due to over-exertion connected with their occupations. These are lecturers, clergymen, teachers, and others who, for several hours each day, are on their feet in a position from which, as a rule, they do not move, but stand almost perfectly quiet. A distinguished laryngologist has pointed out that not infrequently men who come to be treated for the chronic laryngitis, which is known as clergymen"s sore throat, but which is seen so frequently in those who have to talk in the open air, auctioneers, cart-tail orators about election time, and in lecturers to large audiences who do not know how to use the voice, also complain of grievous discomfort from painful knee conditions which often makes the ascent or descent of stairs a painful task. He attributes the simultaneous occurrence of these conditions to some blood dyscrasia, uric acid, or the like, affecting the two most used sets of muscles and organs, the legs and the vocal cords. Whenever I have seen this condition--and circ.u.mstances have brought me into intimate personal relations with many clergymen and lecturers--the trouble at the knee has been due to some yielding of the plantar arch, while the laryngeal condition, if present, was due to an erroneous mode of using the voice consequent upon lack of proper training.
Sufferers of this kind must be warned not to stand absolutely immovable while addressing an audience. Some men stand without moving during a whole hour"s lecture. This is unfortunate, for it obstructs the return circulation through the tense muscles, for the venous circulation was intended to be helped by muscular contraction. Many a man finds, as he comes down from pulpit or platform, that his knees are stiff and sore, though a moment before he knew nothing about it.
The failure to notice any discomfort before is of itself an example of the influence of the mind over the body for the relief of pain.
a.s.sociated Lumbar Discomfort.--The painful condition around the knee which develops when high heels are worn is almost sure to be accompanied by pains, or at least a tired feeling, in the back. If we convince the patient that the trouble is due merely to a derangement of the mechanism involved in maintaining the erect posture we shall have scant need of medicine or even of local treatment. But as the pain is much worse on rainy days, owing to the relaxation of the muscles, we must be careful to remove the patient"s suspicion that the pain must have a rheumatic origin. The restoration of normal mechanical conditions with the removal of the cause will prevent the {412} recurrence of the affection, and if some discomfort remains, the patient will not worry, and the muscles will gradually grow accustomed to the strain upon them. Of course, these conditions of discomfort are more common in those who are not naturally strong, who are run down, who are under-weight, or whose neurotic tendency will make any irritation seem worse than it is.
Heavy and Light Patients.--Two cla.s.ses are likely to suffer more than others from these conditions. They are the people who are overweight and the people who are underweight. Those who are overweight exert much more effort to maintain the erect posture than ordinary people, and, besides, in most adipose persons the distribution of weight is such that a disproportionate amount of it is carried forward of the normal center of gravity. High heels cause a further tilting forward that has to be counter-balanced, and that, at least at the beginning, gives rise to muscular discomfort. In people who are underweight the nutrition of the muscles has suffered, and, as a consequence, they are not able to support the frame as well as before. In them the additional effort necessitated by the tilting tendency of high heels is particularly felt because such people are nearly always among the neurotically inclined.
Muscle Disuse.--Sometimes treatment of these conditions seems to lead up to the disuse of certain muscles and the over-use of others. I followed for several years an interesting case of this kind in which the course of the affection was so typical as to deserve to be recalled. A fuller account of the case occurs in my paper on "Rheumatism versus Muscular and Joint Pains" in _The American Journal of the Medical Sciences,_ August, 1903.
In that case the joint symptoms caused by the pinching of a loose cartilage within the joint occurred suddenly on two or three occasions, so that a surgeon deemed it wise to put the knee in plaster. As a consequence, some atrophy of the muscles of the leg occurred, and a halt became habitual in the gait. Through this halting gait, the muscles of the back on the same side were also spared and thus became somewhat atrophied. Painful conditions developed in the muscles of the other side of the back from the over-use necessary to compensate for the condition on the less-used side. All of the muscles on the affected side became painful, apparently because of the atrophic condition to which they were reduced.
The young man, though with the best of good will, was utterly unable to conquer the tendency to halt in his gait, and so the muscles remained under-exercised and were used at a mechanical disadvantage, with the usual painful result. He went to at least two prominent orthopedic surgeons, who a.s.sured him that all he needed was confidence in himself to walk straight, and that then the normal condition of the muscles and absence of pain would result. But their directions were absolutely without result. He went through the hands of ma.s.seurs, of osteopaths, of rubbing quacks of all kinds, and suffered at least two attacks of artificial eczema as a consequence of the use of turpentine liniments, but he remained after it all in what he considered to be an intensely miserable condition. These cases are practically always cured by definite exercise of the muscles of the affected limb so as to bring them back to their normal tone. It requires special attention for this purpose, however, and the patient"s mind must be brought to understand that at first the unaccustomed use of muscles will cause discomfort, but that this will disappear after a time. These patients are persuaded that they must be "cured" to get well.

CHAPTER VIII
FOOT TROUBLES
The more physicians see of affections of the feet and of painful conditions of the legs due to foot troubles the more they realize that the human faculty of the erect position becomes the source of many discomforts unless care is taken of the muscular apparatus of the legs. There are few people engaged in standing occupations who do not suffer from their feet. These achy sensations are especially bothersome if the patient is run down in health, or is in the midst of worry or irritation from physical or mental stress. Even under favorable conditions there are few who reach old age without serious foot troubles or without, at least, some deformity of the feet, which, by preventing or limiting exercise, have an important influence upon the general health. Careful a.n.a.lysis of the conditions that develop will convince an observer that yielding of the joints of the foot has much to do with the deformities and that the wearing of unsuitable shoes rather than any internal pathological condition is responsible for the foot troubles that are so common.
Foot Deformities in All Cla.s.ses.--An Englishman who visited this country, and who had ample opportunity to observe our people, declared after seeing the bathers at Newport, that there were two interesting peculiarities of American masculine anatomy--the deformity in their feet and the appearance of having swallowed a watermelon whole and retained it within them. The latter condition has doubtless much to do with the causation of the former. Inactive lives, overeating, and the overweighting of flaccid limbs that are not capable of bearing even their normal burden, complicated by tight and ill-fitting shoes, give rise to the deformities of the toes that are so common--hammer toes, over-riding toes, bunched toes, twisted toes, bent toes. Examples of most of these are sure to be seen wherever we observe our men and women bathing. The Englishman"s observation was of our so-called better cla.s.s--at least, our leisure cla.s.s. Ordinarily, it is a.s.sumed that clerks, waiters, and others, who have to stand upon their feet are the princ.i.p.al sufferers from foot deformities. They are, but they are not alone, and a goodly proportion of the population suffers in this way.
Mechanical Factors.--The most important deformity in these cases is a yielding of the arch of the foot with consequent flattening of the instep and lengthening of the foot. This overstretches especially the flexer tendons which run underneath the arch, produces bunions, and gives occasion for the development of corns. The pull upon the flexor longus hallucis which runs along the inside border of the foot, gives rise to the bunion by pulling the big toe outward--in the direction of least resistance. The pressure upon the tendons of the flexor longus digitorum pedis causes the smaller toes to bend somewhat, and this gives rise to projecting angular points on which corns readily form.
Besides, the imperfect action of the muscles of the foot consequent upon the fall of the arch gives rise to plantar corns and callouses that are often painful. The living cushion of muscle which is the best protection against injury, while walking or running, has its vitality interfered with by {414} the fall of the arch and the consequent blocking of the return circulation through the thin walled veins. This gives rise to cold feet and, in those who stand much, to the tender feet that are now so much complained of and for which so many foot powders and appliances are advertised.
Confusion of Rheumatism and Foot Troubles.--Most foot troubles are reflected up the leg because muscles have to be overused or used at a serious mechanical disadvantage. This combined discomfort of foot and leg is readily referred to rheumatism. Some of the pains produced by yielding of the arch are in the ankle, some are in the calf, some in the tissues around the knee, and some even in the muscles and tendons above the knee. It is much easier to say "rheumatism" than to investigate carefully and differentiate the conditions that may be present. Out of forty successive patients who came to the dispensary of the Polyclinic Hospital of New York complaining of rheumatism, eighteen were suffering from flatfoot. Out of twenty-four who thought they had rheumatism in the feet or legs eighteen proved to be cases of flatfoot. Of the others, one was suffering from that rare disease meralgia paresthetica, two were suffering from sciatic neuritis, one was suffering with sub-acute joint trouble consequent upon pinching of a cartilage within the knee joint, and one had a painful condition consequent upon an old dislocation of the ankle due to a fall, accompanied by considerable laceration of the soft tissues. a.n.a.lyses of the cases left no room for the so-called chronic rheumatism which had so easily covered all the cases at the beginning.
