METHODS: Thirsty-eight physical therapists working in rehabilitation settings volunteered to record the components of physical therapy interventions used during 894 treatment sessions for 179 children with spastic diplegia presenting with difficulties in postural control and mobility. Descriptive statistics were used to analyze the general characteristics of the therapists, the patients, and the frequency of the Corresponding Author : Duck-Won Oh odduck@cju.ac.kr, This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License ( which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. interventions. A one-way analysis of variance (ANOVA) and chi-square test were used to describe the components of the interventions and the goals of treatment. RESULTS: In clinical practice, physical therapists primarily used methods including Hands-on: facilitation (n =1990, 36.47%) and Hands-off: practice (n=1355, %). Only 13.96% (n=762) of the interventions allowed patients to be independent or active outside of the treatment sessions. Interventions reflecting the therapeutic aims were performed for sitting (17.53%), standing (18.25%), and walking (27.39%). CONCLUSION: Physical therapists mostly used therapistled interventions to treat impaired postural control and mobility in children with spastic diplegia. Interventions to facilitate independent activity or practice outside the treatment sessions are infrequently used. These types of interventions were used regardless of the aims of treatment.

2 76 J Korean Soc Phys Med Vol. 13, No. 2 Ⅰ. 서론뇌성마비란태아혹은영아의뇌에발생하는비진행성손상으로운동및자세의장애를초래하여활동의제한이발생하는영구적인장애이다 (Rosenbaum 등, 2007). 뇌성마비의감각및운동증상은평생관리하여야하는것으로, 학교및일상생활에큰영향을미친다. 그러므로뇌성마비는많은건강및교육서비스가필요하며, 기능, 삶의질, 교육적성과를높이기위해서는일상생활활동을수행하는동안직면하게되는기능적과제들을극복할수있도록전문적인중재를계획하여시행하는것이중요하다 (Schiariti 등, 2015). Oskoui 등 (2013) 의메타분석보고에따르면, 뇌성마비유병률은 1,000명출생당 2.11명으로보고되었으며, 이중만삭아는 1,000명당 1명이며, 재태기간 32-36주의중도미숙아는만삭아보다 6-10배뇌성마비가더발생하고, 32주미만의극도미숙아는중도미숙아보다 10배더높은것으로알려져있다. 출생시체중 1kg 미만의극도저체중아는생존율이낮기때문에 1-1.5kg 중도저체중아에비하여뇌성마비발생률이낮은것으로알려져있다. 뇌성마비는신경운동의형태에따라강직형 86.5%, 무정위운동형 5.9%, 운동실조형 5.3%, 저긴장형 2.2% 로나타나며, 침범된부위별로는편마비 38.8%, 양하지마비 37.5%, 사지마비 20.9%, 삼지마비 2.8% 로보고되고있다 (Smithers-Sheedy 등, 2016). 대운동기능분류시스템 (gross motor function classification system, GMFCS) 에따른비율은 1단계 35.5%, 2단계 24.5%, 3단계 10.7%, 4단계 12.2%, 5단계 14.1% 로보고되었다. 일반적으로, 강직성양하지마비는신생아또는조산아동들에게서나타나는뇌실주위백질연화증 (periventricular leukomalacia) 으로인해발생하며, 또한두개내출혈, 질식 (asphyxia), 독소등의원인에의해서도발생한다 (McMichael 등, 2015; Shevell 등, 2003). 강직성양하지마비는기능손상이주로다리에서심하게나타나며, 팔의근육은전반적으로영향을덜받거나전혀영향을받지않는다. 다리에서의과도한강직은걷는것을어렵게만들기때문에, 대부분의강직성양하지마비 아동들은무릎의굴곡과요추의전만이증가하여발가락으로서고걷는발끝보행 (tip toe gait) 형태가나타나며, 또한내전근의과도한수축으로인해다리가교차하며걷는가위보행 (scissor gait) 형태도나타난다 (Piña-Garza, 2013). 지난 10년간, 뇌성마비에대한기초적인정보와치료근거는급속하게확장되었으며지속해서변화되어왔다 (Novak 등, 2013). 이러한경향은최신의전문정보를취합하고수렴하기어렵게만드는요인이되었으며, 이때문에물리치료사는종종적합한평가와치료방법을선택하기위한임상의사결정과정에어려움을느끼고있다. 최신의치료적근거에기초하지못한중재를적용하는물리치료로인하여 10-40% 의뇌성마비아동들은효과가입증된치료중재를제공받지못하고있으며, 20% 의아동들은효과적이지못할뿐만아니라종종유해한중재를제공받고있는것으로나타났다 (Flores-Mateo와 Argimon, 2007; Rodger 등, 2005; Saleh 등, 2008). 그러므로임상현장의물리치료사들은강직성양하지마비아동들에게새롭고, 안전하며, 더욱효과적인중재를제공해줄수있도록최근의치료적근거를탐구하여적용하는노력이필요하다. 강직성양하지마비아동들의건강과기능을증진시키고이차적인문제를예방하기위하여체력훈련 (fitness training), 보톡스, 전기자극치료등이임상적으로사용되고있다. 또한, 아동들의신체발달과기능증진을위하여신경발달치료와함께목표- 지향적훈련 (goal-directed training) 과상황-초점치료 (context-focused therapy) 등이효과적인중재방법으로소개되고있다 (Novak 등, 2013; Novak, 2014). 그러나적용되고있는물리치료중재의구체적인내용과절차의기록에대한명확성과세밀함이결여되어있어중재와관련된다양한측면의효과성을분석하는것이매우어려운실정이다 (Pomeroy와 Tallis, 2002). 또한강직성양하지마비아동들의물리치료분야에서사용되고있는여러가지종류의중재들이있음에도불구하고, 중재정의에대한통일성부족과중재적용의기초적인틀과체계성의결여로인하여중재과정을세부적이고정확히조사하는것이현실적으로어렵다 (Marsden과 Greenwood, 2005).

Ⅱ. 연구방법 1. 연구대상자본연구는소아전문물리치료사 38명을대상으로강직성양하지마비아동 179명의물리치료중재기록을취합여진행하였다. 본연구에서자료수집은강직성양하지마비아동을 1주일에한번이상치료하는소아전문물리치료사들의중재기록을통해이루어졌다. 각설문지는개별봉투에넣은후소아치료전문병원의소아담당물리치료사에게보내졌다. 총 49명의치료사에게아동 245명을대상으로 1225부의기록지를배부하였으나이중 239부가회수되지않아 986부의자료가취합되었다. 그리고회수된자료중답변오류가있는 61부와대상자선정조건에부적합한 31부를제외한 894부의기록지를최종분석에이용하였다. T able 1은본연구의대상의물리치료사들과강직성양하지마비아동들의일반적인특성을설명하는것이다. 본연구는물리치료사들의중재행위에대한기록을기본자료로하는것이므로, 개인정보및치료행위에대한윤리성과관계없는것이며 (Tyson과 Selley, 2004), 이에따라윤리승인과정은생략되었다. 2. 물리치료중재기록본연구에참여한물리치료사들은총 12개병원의물리치료실에서근무하고있었으며, 각각본인이적용하는중재행위의빈도를기록지의양식에따라기록하였다. 실제로수행하는치료중재를기록하기위하여강직성양하지마비아동의나이, 심각성, 합병증유무등에상관없이모든중재행위를기록하도록요구하였다. 본연구에서강직성양하지마비아동에대한물리치료중재는사용하는중재를직접기입하여기록하는 뇌졸중물리치료중재기록 (stroke physiotherapy intervention recording tool) 의항목을사용하여기록되었다 (Tyson 과 Selley, 2004). 자료를수집하기전에물리치료사들이중재기록지에서사용된중재및용어에대해충분히이해할수있도록기록지내중재및용어에대한설명서를함께제공하였다. 사용한물리치료중재의적용시간에따라 5분미만은 1로, 5-10분은 2로, 10-15분은

Ⅳ. 고찰일반적으로, 임상현장의물리치료사들은강직성양하지마비와같은중추신경계손상을받은환자들의자세조절과운동성을향상시키기위해어떠한물리치료를시행할것인지에대해많은고민을하고있으나, 실제로사용하는중재를어떻게기록하고분석할것인지에대한연구는매우드물다 (Tyson 등, 2009). 본연구는소아전문물리치료사들이강직성양하지마비아동들의자세조절과운동성을증진시키기위하여사용되는중재를기록하여분석한최초의연구이다. 본연구의결과는물리치료사들이치료의목표와상관없이치료사중심의중재를주로적용하고있는것으로나타났으며, 치료시간이외의독립적이거나일상생활에서의수행에대한중재는거의사용하지않은것으로나타났다. 본연구에서소아전문물리치료사들이강직성양하지마비아동들의치료를위하여 촉진 의중재를가장빈번히사용 (36.47%) 하는것으로나타났다. 전통적으로사용되는뇌성마비치료방법의목적은물리치료사가수동운동치료기법을사용하여움직임의질을향상시키고근육의긴장도를정상화함으로써환자의비정상적인움직임을예방하고, 정상적인활동을가능하게하는움직임을유도하는것이다. 이러한치료의특성은물리치료중재중의하나인 촉진 으로설명되며, 임상현장에서가장많이사용되고있다 (Lennon과 Ashburn, 2000; Lennon, 2001). 물리치료사가환자를직접도수접촉하여시행하는 촉진 은수동적인중재이며, 이를표방하는대표적인치료는신경발달치료 (neurodevelopmental treatment, NDT) 이다. NDT는특별한핸들링기술을이용하여근긴장도, 반사, 비정상적인움직임패턴, 자세조절, 감각, 인지및기억등감각운동요소들을조절하는것을목적으로하는뇌성마비에대한치료개념이다 (Butler와 Darrah, 2001). 미국뇌성마비발달의학회 (American Academy of Cerebral Palsy and Developmental Medicine) 에따르면 NDT를받은환자가약간의운동범위에서즉각적인개선을보였지만, 기능적인활동의회복, 정상적인운동발달의촉진, 구축의예방, 비정상적인운동반응의억제등의효과에대한일관성있는증거는없다고하였다 (Butler와 Darrah, 2001). 또한 Novak 등 (2013) 은 NDT를더효과적인치료로볼수있는정황은없으며, 강직성양하지마비아동들에게임상에서전통적인 NDT를계속해서사용하는것을합리화하기어렵다고보고했다. 본연구에서두번째로가장빈번히사용된중재는 연습 이었다 (24.83%). 연습 은물리치료사의직접적인도수접촉없이면밀한감독하에뇌성마비아동들이활동요소들을연습하는것이다. 이에반해독립적인연습을위해환자교육하기 (10.09%), 보호자혹은건강관리전문가교육하기 (3.13%), 장비사용방법에대해교육하기 (.73%) 등과같은치료시간이외의활동을장려하려는시도는 14% 정도에불과하였다. 대부분의물리치료사들은운동패턴의개선 ( 또는 운동의질 ) 이자동으로기능향상을가져올것이라고믿기때문에, 치료시간이외의활동을관리하는것이필요하다고생각하지않을수있다 (Lennon, 2001). 그러나 Novak 등 (2009) 에따르면, 치료실에서의연습이가정프로그램으로연결되었을때운동활동, 자기관리, 기능에서의증진이나타났다고보고했다. 그러므로치료실에서의연습으로인해운동패턴의개선이보인다면, 반드시치료시간이외의활동관리도함께시작되어야한다. 본연구의전반적인결과는가동술, 촉진, 연습과같은치료사중심의중재 (therapist-led intervention) 를주로사용 (69.71%) 하는것으로나타났으며, 이러한중재

10 84 J Korean Soc Phys Med Vol. 13, No. 2 는치료시간동안치료사가주도하여환자들에대한전반적인치료를안내하고지도 / 감독하는것을의미한다 (Tyson과 Selley, 2004). 또한, 목표에따른사용된중재의결과에서는물리치료사들이강직성양하지마비아동들의앉기자세, 서기자세, 걷기의회복을위하여이와직접적으로관련된중재를상대적으로적은빈도로사용 (21.05%) 하고있는것으로나타났다. 선행연구들의결과는 NDT와같은신경손상지향적인치료법이근거가충분하지못하고, 그효용성에대한문제를제기하고있다 (Helders 등, 2001; Damiano, 2006). 최근의치료개념은운동학습의원리를반영하여목표- 지향적으로구성된기능훈련이효과를크게강조하고있다 (Ma 등, 1999; Schmidt와 Lee, 2005). 이러한운동학습의개념으로인해최근의뇌성마비치료패러다임은기존의촉진 / 억제기술에서보다역동적이고목표-지향적훈련으로변화되고있다 (Barbeau와 Fung, 2001; Carr와 Shepherd, 2003). 또한, 최근의연구들에서기능적인활동과제를반복연습하는과제-지향훈련이나유사한프로그램의효과가매우큰것으로보고되었다 (Leroux 등, 2006; Peurala 등, 2005). Polatajko와 Cantin (2010) 은운동학습이론에근거한수행-기반 (performance-based) 또는하향식 (top-down) 접근법을설명하였으며, 이러한중재들이신체구조와기능등근본적인장애와는관련없이특정과제또는목표훈련에직접적으로초점을맞추고있기때문에기능향상에보다효과적일수있다고하였다. 그러므로강직성양하지마비아동들에대한치료적중재는목표또는과제에적합한직접적인운동과제를반복연습하는방향으로이루어져야할것이다. 본연구는향후연구에서보완될수있는몇가지제한점을가지고있다. 첫째, 본연구는뇌성마비중강직성양하지마비아동을치료하는소아전문물리치료사에국한하여진행되었다. 그러므로본연구의결과는강직성양하지마비형태이외의다른뇌성마비아동에대한결과로해석될수없다. 둘째, 본연구에서는강직성양하지마비아동에대한중재기록을위하여뇌졸중환자들의중재기록지의항목들을사용하였다. 중추신경계가손상된성인환자와아동환자의신체 특성이다를수있고중재항목간의차이가있을수있으므로중재기록에대한타당성의문제가제기될수있다. 향후의연구는이러한제한점을보완하여모든형태의뇌성마비아동의물리치료중재를기록하여분석할수있도록진행되어야하며, 또한뇌성마비에특화된물리치료중재를기록하고분석할수있는전문기록지의개발이이루어져야할것이다. Ⅴ. 결론물리치료중재에대한정확하고상세한기록은임상에서성공적인중재의적용을가능하게하고, 질높은연구의기본적인토대가된다. 본연구의목적은물리치료사들이뇌성마비중강직성양하지마비아동을치료할때어떤종류의중재를적용하는지기록하고분석하는것이다. 본연구의결과는소아전문물리치료사들이강직성양하지마비아동들의자세조절과운동성을위해치료사중심의중재를주로활용하고있는것으로나타났으며, 치료시간이외환자가일상생활에서독립적혹은능동적수행에대해장려하는중재는거의사용하지않은것으로나타났다. 이러한결과는최근의치료적인근거에적합하지않은것으로판단된다 (Novak 등, 2009, 2013; Polatajko와 Cantin, 2010). 따라서치료시간내에서의연습및훈련이과제또는목표 -지향적으로선택되어사용되어야하며, 치료시간외독립적인활동또는일상생활에서의수행즉, 가정프로그램등으로연결되어야한다고할수있다. 향후의연구는본연구에서나타난제한점을보완하여모든뇌성마비유형환자를대상으로하고, 많은대상자와다양한치료환경에서연구가이루어져야할것이다. 본연구는물리치료를받고있는강직성양하지마비아동들에게적용되고있는중재를기록하고분석한첫번째연구로, 뇌성마비아동들에게어떠한중재를사용하는지기록하고분석하여기술하였다는데큰의미가있다. 또한, 향후의뇌성마비아동에대한물리치료연구를위해유용한정보를제공해줄수있을것이다.
