II. Personality Maladjustment of Physically Handicapped There exist in the litct*;tturt? two scl~ot~l~ of thought cottccrttittg the route by which personality tttitlatl,jttst.tttt~ttt occurs it1 the l~ltysit~;tlly ltsttdicapped. One group of authors feels that thtl tnort~ ~~rrsewt~ 01’ ;1 physical handicap is, in itself, sufficirttl to ~~rotlut~c personality disorder. Others tnaintain that poor family emotional environment is the prime factor in causing maladjustment. Phelps says, “. . . the presence of t.he cerrlwal palsy itself is not the basic 1factor] for the type of response to sit.uat.iotts, hut. rather [it is] ihc specifici t.ype of motor disturbance which is the detertninittg .factnt*. ” Responses arc considered psychologic varia.tions ot’ first,. the early acquisition ol’ t.he hantliAthetoid cap, and second, the result of t,he various t,ypes of t.he involremenl. paGent.s, for esample, Phelps foutttl t,o show almormn.1 displays of both anger 1122
and affection alternately, these iiswings” being so constant. as to constitute part of the athctoid picture.4 Wile.L believes that. crippling af’fscts intelligence, stability, and social equilibrium through interference with I~OYII~;~ (I(~vclopment, afleeting the ’ ‘ ornotional. evolution. ” The appearance of an inferiority complex in childhood as the result of crippling has l)ecn studied in conditions other t.han cc!rcbral palsy.” lmd’~ feels that the parent relationship is the decisive factor when personality maladjust.ment occurs in children with cerebral palsy. The child’s atljustmcnt depends on t.he emotional sbahi1it.y rai.her than t.he intellectual or mxrly normal mental attainment of the parents. Children of nom:~l development presented the major adjustment problems, “. . . some of t.his group [being] in practical control of the &nation through domination over slaves who ea.nnot cope with the demands of a dotheir parents ,-willing mestic tyrant who is physically helpless. ” I

This behavior seyuc~r~ewas Npeated at several visits over a long period. Alth~mgh the use of local anesthesia helped to diminish the reaction slightly? this patient has never been al)le to control the hyperkinetic effect to the extent of hecoming a fit. subject. for dental treatment. 1’1)the boy, t.hr dentist soon l~camc “Hitler.” and epithet he had fomc~~ly appliccl to an anthoritativr l)hysiothel.;l.pist who~t~ he ’ ’ hated. ’ ’ IV The manifestation of emotional conflict through yhysiologic mechanisms of the body has been widely observed. It does not seem unusual to find such reactions first evidenced through a particularly unstahlc ph,vsiologic system, if one is present. .Est.rcme emotional tension is a ul)iquitous experience in indivitluals whose fear of dental procedures is uncommonly exaggerated. This condition has With paCents who have had been described specifically as dentd nn.~iaty.~ no previous experience with dent.al l)rocedures, awl mow lx~rticularly with rest.ora.tive dentist.ry, tlental ansisty is amplified by fear of an unknown danger. It WRYbe said of both of the cases cit,ed that a tlental i\lGety. ol)erat.ing on an already labile neuromuscular system, produced the psyehomot.or effects tlescrihed. That the anxiety esl)erienced by 1)ot.h patients was largely of an unconscious nature may he deduced from the fact that, both espressctl :I. willingiicss to cooperate in treatment. procedures : their inability t.o do so as the result of unconscious anxiety was translated itlto violent i~lcoortlin;ttc ttlovements via the neuromuscular system. When more closely esamined a pertiuetlt difference is found to esist. hetween the two ca.ses. Case .1 resl)ontletl well to the use of local :lnest.hcsia. I II the absence of pain he eshibited little or no hyperkinetic reaction during treatment. It may lx inferred that a discreet fear of pain was the underlying ca,use ot’ this paGent’s dental anxiety, and that, other factors played little 01 no part in producing 6he psychomotor effects. Case 2, however, did not show any a.pprecial)le reduction in the hyperkinetic reaction over a, long period, despite at.tempts at reassurance and reeducation. and the use of local anesthesia. 111(~ontraat to C’ase1, the adjustment of t.his patient. to his halldi~a.1) was l)oor, as W:ISthe emotional environ-

V The occurrence of similar motor reactions to attempts at dental treat.ment ha.s been described in IWO (*ilses of athetosis. 1t does not sc\?mpossible to explain the violence of the transition from the usnnl dyskincsia of t.hese patients to the sevel;e hyperkinrtic cffecia observed on the basis oCthe physical condition alone. Emotional environment has hecll suggested as ;I likely ailditional factor to t.he at.hetosis. Social requirements inv;~1*ial)ly ~lcman- ~hc demantls placed upon them. IJnquestionably much of the insecurily evident in athctoid pAient.s results directly from t,he neul’orllllsclll;lr disability, illltl may be cow&lerecl ill1 unavoidahle consequence of it. It. is clearly apparent. however, that the emc~Conal environment. of such patients has a clerl) and I)ervatling eff ccl on the personality. In varying degrtae 1x)t.h faef(>rs opcratc to prodncr the anGty and insecurity. In the first case descril)thd the cwaellent. filmily emotional background and high morale permitted rapid adjustment to a ~mparativtly discreet. manifestation of anxiety. A reverse condition existed in the second G~SC.in which an unhealthy family emotional environment resultetl in a iliffnse x1siet.y and acl.justmcnt an overwhelming insecurity which prerentccl il ny S:ltiSfilctOr;y when dent.al treatment Was attpmptecl. From the foregoing it. may 1~ coneMet tll;lt. ;I.tht>tosis,present to a Momparable degree in both patients. Was not the tlecisivr factor in t,he production of the estreme hyperkinetip reactions. Early emotional environmenl: had created anxiet,y st.nt.es which woe apparent.
