Tel: Fax: Sayeo@hanmail.net Acknowledgement This work was supported by a 2-Year Research Grant of Pusan National University. Objectives: The purpose of this study is to investigate the clinical trial research trends in regards to the neurofeedback training (NFT) in Korean journals. Methods: We researched articles published in Korean journals from 2000 up to 2013 and were related to the NFT. We searched six electronic databases to find relevant articles, using the term neurofeedback. Results: 1) 6 single group comparative studies and 31 randomized controlled trials were found. 2) Healthy volunteers and students were most frequently studied with neurofeedback training. Other studies included attention deficit hyperactivity disorder (ADHD), Poststroke, panic disorder, premenstrual dysphoric disorder (PDD), temporomendibular disorder (TMD), and obesity. NFT interventions were attempted in diverse training protocols and assessed with many different outcome measurements. 3) Most studies showed effective results after NFT. Conclusions: NFT is increasingly studied and used in various clinical fields. Also, there have been efforts to adopt NFT in Korean medical clinics and researches, and more rigorous and innovative studies are needed in the future.

10 280 The Review for Studies of Neurofeedback Training 구가 1편, 전두엽 Alpha 파비대칭성이동기에미치는영향에대한연구가 1편, 주의력결핍과잉행동장애아동의아형에따라서로다른뇌파대역을강화한연구가 1편이었다. 그외 6편의논문에서는뉴로피드백훈련프로그램에있는훈련방법과훈련게임에대해기술하였다. 훈련횟수나기간을정확히기재하지않은연구가 9편이었으며, 회기당훈련시간은최소 15분에서최대 60분, 훈련기간은최소 3일부터최대 9개월, 훈련횟수는최소 4회기에서최대 90회기, 훈련빈도는연구마다 1일 1회부터주당 1회까지다양했다. 5. 평가도구임상연구중가장많이사용된평가척도는뇌기능지수 (Brain Function Quotient) 로뇌기능지수를평가도구로사용된연구는 21편이었으며그중뇌기능지수만을평가도구로사용한연구가 6편이었다. 뇌기능지수외다양한설문검사및신체검사가시행되었다. 주로시행된설문검사는한국판간이정신상태검사 (Mini-Mental State Examination - Korea; MMSE-K), 한국판주의력결핍및과잉행동장애평가척도 - 부모용 (Korean-Attention-Deficit/Hyperactivity Disorder Rating Scale; K-ARS), 기분상태설문지 (Profile of Mood ; POMS), 색채누진행렬지능검사 (K-Raven CPM [coloured progressive matrices]; K-Raven CPM), 교사용유아다중지능평가검사지 (Korean Multiple Intelligence Development Assessment Scale-My Young Child; MIDAS-MYC), 자기주도학습능력설문지 (Self-directed learning ability questionnaire) 2편이었으며, 대상질환및평가대상에따라스트레스척도, 피로척도, 삶의질척도, 우울척도, 불안척도불면척도, 공황장애척도, 증상에대한시각화척도, 지능검사등이사용되었다. 객관적인신체검사로는신경가소성예측인자 (BDNF, NGF), 심박변이도, 면역세포, 신체계측, 혈액생화학적분석이사용되었다. IV. 고찰 본연구에서는국내학술지에발표된뉴로피드백훈련을시행한임상연구를선별하여그결과를분석하였다. 국내 데이터베이스에서본연구목표에합당한연구 37편을선정하였으며, 이중단독치료 ( 뉴로피드백훈련 ) 군과대기군을대조군으로하여비교한연구가 23편으로가장많았으며, 단일군전후비교연구 6편, 병행치료 ( 뉴로피드백훈련군과다른치료를결합 ) 를실시하거나다른치료군과비교한연구가 8편이었다. 선정된임상연구논문중뉴로피드백훈련시행전후비교연구와대기군을대조군으로한연구에서는모두뉴로피드백훈련이유의한효과를보인다고보고하였다. 뉴로피드백훈련을시행한결과, 공황장애증상의호전, 월경전불쾌감증상감소, 주의력결핍및과잉행동충동성척도점수감소, 비만환자에서의체지방량감소와식사행동의변화, 주의력상승, 좌우뇌균형상승, 창의력척도점수상승, 피로, 스트레스척도점수감소, 면역력이증가하고, 뇌기능지수의개선이보이고각종정서, 건강척도, 뇌파활성화, 인지기능척도상승, 자기주도학습능력, 통증, 수면질, 삶의척도개선, 바둑수행력, 사격수행력상승이나타났다 19-22,24-27,29-39,43-46,49-52). 가짜뉴로피드백훈련을대조군으로한논문이 2편있었는데대조군의피험자에게는뇌파상태와무관하게무선으로변화하는시각적자극을제시하였다 18,40). 호흡명상과뉴로피드백훈련을병행한연구 18) 에서는가짜뉴로피드백훈련을시행한대조군에서집중력과인지강도에서유의한향상을보였으며, 초등학생을대상으로뉴로피드백훈련후회상기억과재인기억수행변화를관찰연구 40) 에서는뉴로피드백훈련집단이유의하게우수한수행결과를보였다. 또한뉴로피드백훈련과다른치료방법을병행하거나다른치료방법과비교한 8편의연구 18,21,23,41,42,47,48,54) 중, 근력복합트레이닝과뉴로피드백훈련을함께한실험군의혈중 BDNF 수치가근력복합트레이닝훈련군보다유의하게높았으며 54), 주의력결핍과잉행동장애아동의부주의와과잉행동 / 충동성점수는뉴로피드백훈련집단에서약물치료집단에서보다유의하게감소되었다 21). 그러나다른 6편의연구에서뉴로피드백훈련은다른치료방법과효과면에서유의한차이를보이지않았다. 뉴로피드백훈련후긍정적효과가보고된논문은대부분훈련전후비교연구나, 대기군을대조군으로한연구였다. 가짜뉴로피드백훈련을대조군으로한연구와뉴로피드백훈련과다른치료를비교한연구들의결과가일관되게나타나지않아 Fuchs 등의연구 55) 에서제기된바와같이뉴로피

11 JH Lim, WY Seong 281 드백훈련의플라시보효과에대한가능성이어느정도인정된다고할수있다. 또한, 보고된긍정적효과가뉴로피드백훈련에의한것만이아니라훈련자의의무감, 새로운치료법에대한기대감, 치료사에대한신뢰, 기타생활변화등이모두반영된결과일수도있다. 향후피험자의기대와같은사회심리학적요소가뉴로피드백훈련의치료효과에공헌하는측면, 다른치료방법과구분되는뉴로피드백훈련이갖는차별적인효과에대해서연구가이루어져야할것으로사료된다. 본연구는뉴로피드백훈련을다양한질환과대상에적용한연구결과를모두취합하였기때문에다양한훈련방법과평가도구가사용되었다. Bata-SMR 모드를사용한연구가 4편, bata-smr 모드와 alpha-theta 모드를사용한연구는 3편, Alpha 파강화훈련을시행한연구 2편, 전두엽 Alpha 파대칭성훈련을한연구가 1편, 전두엽 Alpha 파의비대칭성을유도한훈련을한연구가 1편이었고, 두뇌이완훈련, 집중력훈련, 알파파의전두엽에서의좌우균형훈련을사용한연구가 1편이었다. ADHD 아동을대상으로한연구에서는연구대상자의증상에따라훈련모드를달리하였고, 그외 15편의연구에서훈련전피험자의자기조절능력을분석후피검자가피드백한뇌파중상대적비율이낮은주파수를피검자의훈련모드로선택하였다. 뇌영역에따라출현하는뇌파가다르고특정활동에따라주된활동을보이는뇌파가다르므로, 훈련자가뉴로피드백훈련으로활성화하거나억제하려는뇌파는관련질환과연구목적에따라차이를지니게된다 56). 대표적인뉴로피드백훈련모드중 bata-smr 모드는집중력장애, 불안, 우울, 간질, 통증, 뇌졸중등두뇌손상후유증등의치료에주로이용하며 57), 체성감각을억제시켜근육의긴장도를낮추고 58), 수면의질을개선시킨다는보고가있다 59). Alpha-theta 모드는편도를포함한변연계를안정화시키는효과가있는것으로알려져있으며대개무의식영역에서기원하는공포증, 외상후스트레스장애등의증상치료및치유되지않는감정적기억의완화, 깊은명상의유도등을위해사용된다 57,60). 전두엽비대칭은정서와밀접한관련이있어우울증환자에게서전두엽에서의알파파의비대칭이우울증환자에게서나타나고 61), 좌반구전전두엽은접근체계로서의욕구행동및긍정적정서를발생시키고우반구전전두엽은철수체계로서혐오적인자극에서철수하 려는경향성과부정적정서를발생시킨다는보고가있다 62). 그러나뇌파와특정인지능력혹은감정에대한관련성은연구마다일관적이지않아 47) 특정질병에특정훈련을일괄적으로적용하는것은무리가있어훈련전뇌파분석을통해서훈련자의뇌파상태에맞는훈련모드를사용하는것이임상현장에서는보다실제적일것으로사료된다. 평가지표로공황장애, 주의력결핍과다행동장애, 월경전평가척도, 스트레스, 피로, 정서, 지능, 인지, 동기, 삶의질, 통증척도등의설문평가와신체계측, 혈중신경인자, 혈액학적분석, 면역세포, 심박변이도등과같이신체변화를측정하는객관적평가가사용되었다. 그중가장많이사용된평가지표는뇌기능지수인데뇌기능지수는특정뇌파의세기나주파수, 혹은뇌파간의비율을점수화한것이다 63). 임상연구에서뉴로피드백훈련후뇌기능지수가유의미하게변한것은뉴로피드백훈련이훈련자의뇌파를변화시켜원하는뇌파상태를유도하였다는것으로해석할수있으나뇌기능지수가신체적, 정서적건강과인지, 지능등의객관적지표로활용되기위해서는경험적증거의축척과관련성연구등의후속연구가필요할것으로사료된다. 뉴로피드백훈련의훈련시간과훈련횟수는 15분에서 60 분, 4회에서최대 90회로다양하였고, 훈련빈도와훈련기간도주 1회부터 1일 1회, 3일부터 9개월까지다양하였다. 몇몇의연구에서원하는뉴로피드백훈련의긍정적인효과와이를지속적으로유지하는데필요한훈련횟수를 20회이상으로보고하고있으나 64), 표준화된치료빈도및기간을확립하기위한향후연구가필요할것으로생각된다. 뇌파는인간의정서및정신의활동상태와관련을가지므로심신일여 ( 心身一如 ) 의전인적인체관에기반한한의학에서진단적, 치료적활용가능성이높으며 11), 뇌파의변화를측정하여원하는방향으로변화시키는뉴로피드백훈련또한인체항상성을유지하기위한자생력을키워가는자율적훈련이란점에서한방정신요법과일맥상통한면이있다 65). 실제한의학임상현장에서뉴로피드백훈련이사용되고있고그효과와한의학적활용에대해서관심이높아지고있으나한의학계에서의임상연구는증례보고에치우쳐있다. 이에본연구에서는먼저국내학술지에발표된뉴로피드백훈련연구동향을살펴서실제임상현장에서의치료도구로의활용과한의학연구의설계에참고하고자했다.

12 282 The Review for Studies of Neurofeedback Training 선정된연구를살펴본바주의력결핍과잉행동장애, 공황장애, 뇌졸중후유증, 월경전불쾌장애, 측두하악장애, 비만환자, 유아, 아동, 청소년, 성인운동선수등다양한집단을대상으로뉴로피드백훈련에대한연구가수행되고있었으며, 증상개선, 스트레스감소, 뇌기능향상, 수행력증가에일정한효과가있었음을알수있었다. 그러나많은수의연구가비질병인을대상으로하고있고특정질환및증상을대상으로한임상연구는상대적으로적어서특정질환에대한뉴로피드백훈련의치료효과에대해일반화하기위해서는더많은후속연구가필요하다고생각된다. 또한연구의질이대체적으로낮고치료행위외다른요소가치료결과에반영될가능성이배제되지못하였기때문에, 향후연구에서는뉴로피드백훈련의플라시보효과의가능성과환자및치료자의특성등에따른다른치료요소가미치는영향을고려한정밀하고과학적인연구설계와분석방법이요구된다. 뉴로피드백훈련은환자의뇌파상태에맞는훈련모드를설정할수있고, 환자주도하에치료자와상호협조하여치료한다는점에서한방정신요법과유사한점이많아한방신경정신과질환의치료에응용될수있는가능성을크게지닌다. 따라서한의학임상교육에뉴로피드백훈련의임상적용을확대함으로써치료과정에적극적으로도입할수있을것이며, 다양한한의학적치료와함께활용함으로써뉴로피드백훈련방식을응용하는등의다양한시도가요구되며, 그유효성에대한연구도필요하다고하겠다. 본연구에서는국내에발표된뉴로피드백훈련에대한임상연구만을대상으로분석, 고찰하였으나향후해외여러나라에서이루어지고있는연구에대해서도지속적연구가필요할것이다. V. 결론 본연구는뇌파를이용한생기능자기조절 ( 뉴로피드백 ) 훈련의한의학임상에서의활용제고를위하여 2000 년부터 2013 년까지국내학술지에발표된논문을대상으로분석, 연구동향을고찰하여다음과같은결론을얻었다. 1. 뉴로피드백훈련에대한임상연구는총 37편으로단일군전후비교연구가 6편, 뉴로피드백훈련군과대기군을비교한연구가 23편, 뉴로피드백훈련과다른치료를결합 하거나다른치료군과비교한연구가 8편보고되었다. 2. 뉴로피드백훈련의대상이비질병인인연구가 28편으로가장많았으며, 그외주의력결핍과잉행동장애혹은학습능력저하및주의력저하를호소하는아동을대상으로한연구가 3편, 만성뇌졸중환자가대상인연구가 2편, 공황장애, 월경전불쾌장애, 측두하악장애, 비만환자를대상으로한연구가각각 1편으로보고되었다. 3. 뉴로피드백훈련방법절차, 시간, 회수, 빈도및평가방법은연구대상과질환에따라다양하게나타났다. 4. 뉴로피드백훈련후, 단일군전후비교연구와대기군을대조군으로한연구에서모두뉴로피드백훈련후유의성있는효과가보고되었으나, 가짜뉴로피드백훈련을대조군으로한연구는 2편중 1편에서뉴로피드백훈련과다른치료를비교한연구는 8편중 1편에서뉴로피드백훈련의유의성있는효과가보고되었다.
