Conclusion This study showed that the intervention including activating extensor muscles and widening base of support on the hemi-side foot provided benefits on repetitive sit-to-stand and walking positively. Key words Extensor Activation, Sit-to-stand, Walking 책임저자 Bae-Young Song(oper0600@naver.com) 논문접수일 2015 년 4 월 30 일수정접수일 2015 년 5 월 25 일게재승인일 2015 년 6 월 20 일 I. 서론 수의적움직임은특별한환경에서움직일때선행적자세조절 (APAs) 이발생되는적절한자세조절을필요로한다. 1) 그러므로자세조절에반응하는근육은다른근육들보다먼저활성화된다. 2) 앉은자세에서일어서기 (Sit to Stand, STS) 동작은독립적인일상생활에서필수적인요소이다. STS는안정된앉은자세로부터상대적으로불안정한선자세로의전환이포함되며, 하지와몸통근육의조화로운수축이요구된다. 3) 그리고의자에서일어날때, STS움직임패턴은의자의높이와발의위치와같은환경적인매개변수에따라다양하다. 그러나앉은자세가제한된다면, 명확한 STS궤도의모델은최적화될수있다. 4) 몸의질량분배와기저면 (base of support, BO)S 에대한신체의무게중심 (center of mass, COM) 은일어서는동안균형을유지하는데에중요한요소이므로, 신경시스템이 COM의움직임을조절하는것은사실로추정되어왔고, 안정적으로일어서기동작을수행하기위해서는충분한관절회전력, 좁아진지지면 ( 두발 ) 에압력중심을안정적으로이동시키는능력, 그리고환경에따라일어나는전략을수정하는능력 이필요하다. 5,6) Cheng 등은일어서기동작을 3단계로분류하였다. 첫번째는초기단계로참가자의몸통굴곡과수직지면반발력이감소되는단계가나타나며, 두번째로실행단계는가장짧은단계로수직지면반발력이생성되고가장많은수직반동이생성되는시기이다. 7) 세번째로서기단계는가장많은수직반동이있을때시작되어마지막서기자세로몸전체의수직힘이안정화되는시기이다. 특히앞정강근과넙다리근은일어서기동작동안질량중심앞쪽과위쪽으로이동시키는데중요하며, 넙다리뒤근과가자미근은원심성수축을통해이러한움직임의정도를조절한다. 넙다리근과앞정강근은엉덩이떼기시점전에넙다리근은엉덩이떼기직후에중요한역할을한다. 8) 앉아서일어서기동작 (sit to stand) 와서서앉기동작 (stand to sit) 동안전경골근은몸이앞으로움직이기전에발을안정화시키기위해선행적자세조절에가장대표적인근육으로보이며, 상호적인활성화패턴에따르면, 가자미근의반대작용은예상되어진다. 9,10) 그러므로발의안정성에중요한전경골근의빠른활성은가자미근의활성수준에의해좌우될수있다. 7) 그리고 sit to stand 와 stand to sit에서, 하지에대한몸통의전방움직임은움직임전에전경골근의활동타이 하퇴신근촉진이반복일어서기와보행에미치는효과 1

NEUROTHERAPY 2015;19(2):1-4 밍이필요하다. 이는 CNS가움직임의방향에대한작은변화에반응하여근육의선행적활동을조절할수있다는것을뒷받침한다. 1) 상호억제 (reciprocal inhibition) 란주동근의수축에의해서수의적인운동을할때동시에길항근이억제되는현상을말하며 11, 건강한사람의경우수의적인동작을하는동안길항근의 α-운동신경원의흥분성은척수억제경로의중추변조에의해조절되는데, 근긴장이상증에서는이상호억제기전의장애로주동근과길항근의동시수축이일어나며이로인하여운동장애가초래된다. 11,12) 그리고경직형뇌졸중환자나척수손상환자는이러한억제경로의결함으로인해주동근과길항근의수축과이완이제대로이루어지지않는다. 13) 여러문헌들은뇌졸중과관절장애및신경근육질환과같은건강상태는 STS움직임을할때특별한변화양상을보인다고말한다. 14) 뇌졸중은임상적으로뇌의침범부위에따라감각, 인지, 지각, 언어기능의손상및의식수준의변화등을포함하여다양한손상을일으키며일반적으로뇌병변부위의반대편에운동결핍으로인한마비혹은쇠약을특성으로한다. 15) 특히, 뇌졸중환자의문제점은비대칭적체중지지와비정상적인신체의균형, 체중을사방으로이동하는능력의결함, 섬세한기능을수행하는특수한운동요소의상실등으로일어서기동작시체중의중심이전, 상방으로이동하는데어려움이나타나며, 앉은위치에서일어서기동작시자신의비대칭적인움직임을인식하지못하고있다. 16,17) 만성뇌졸중환자들이여전히비효율적이고불안한방법으로기능적활동을수행하고, 재활시기동안환측사지의사용을피하면서적절하지못한움직임을통해기능적활동을하기때문에, 따라서본연구에서는환측발목의길항작용을촉진하여환자가좀더나은 sit to stand를할수있도록만드는데초점을맞추었다. 8) II. 연구방법 본연구는뇌단층화촬영 (CT) 이나자기공명영상 (MRI) 에의해뇌졸중으로진단을받고연구에참여하기로동의한, 연구조건을충족한환자 1명을대상으로주 3회 1회당 30분씩총 4주에걸쳐실시하였다. 연구대상자의선정조건은뇌졸중으로인하여편마비가된발병기간이 6개월이상인환자, 호흡계및근골격계질환의과거력이없고, 연구자가지시하는내용을이해하고따를수있는환자, 수동적배측굴곡각도에제한이있는환자, Modified Ashworth Scale 경직정도가 2단계이하인환자로정하였다. 그리고환자에대한부가적인평가로 5 번앉았다일어서기동작시시간을측정하기위한 Five Times Sit To Stand (FTSTS) 와동적균형검사인 timed up go test (TUG) 또한실시하였다. FTSTS 통해 Sit to Stand (STS) 검사를하였다. 이검사는안락하고조용한검사실에서 STS 검사수행시최대한의근긴장도를줄이기위하여충분한휴식을취하도록하였다. 등받이가없는침대 (bobath table) 에앉아양팔을가슴에교차한후상지의도움없이일어서고앉는동작을 5회실시하는데소요되는시간을측정하는것이다. 하지만본연구의대상자는일어서기동작시상지의도움이필요하여 FTSTS시상지를사용하였으며환자가평소에일어나는대로편안한 STS를실시하였다. 그리고일어선자세는체간을바로세우고슬관절과고관절을완전히신전한상태로정의하였으며, 검사에앞서대상자들에게 STS 검사를정확하게수행할수있도록구두지시와 1회의시범을보여주었고, 시작 명령에따라앉은자세에서일어서는동작을 5회반복하였다. STS 검사에소요되는시간이적을수록하지근력과동적균형능력이우수하다고할수있다. 18) TUG 는평편한바닥에팔걸이가있는의자를놓고의자에서 3m 떨어진곳에표시물을설치한다. 보행방법은평상시사용하는신발을착용하도록하며보행할때보행보조도구 ( 지팡이, 워커 ) 등을사용할수있으나발목보조기또는다른사람의물리적인도움은받지않도록한다. 보행측정시간은연구대상자가팔걸이가있는의자에편안하게앉고양발은바닥에놓여있는상태에서 일어나서반환점을돌아의자에앉으세요 라는연구자의지시에따라 3회실시하여평균시간을기록하였다. 19) 치료방법은다음과같다. 1 바로누운자세에서발의내재근 (intrinsic muscle) 을활성화시켜외재근을이완시키고교각운동을통해골반주위근에협력수축및슬괵근근위부를강화시키고지면에대해발뒤꿈치를누를수있는능력을향상시켜하지에체중을입력하여감각에자극을준다. 2 앉은자세에서골반움직임과함께코어 (core) 근육을활성화시키고, 척추의선택적움직임을만들어체간을바로세운다. 그리고발의넓은접촉면을위해발의내재근활성과발외측면의체중지지능력을향상시키고, 동측하지의근활성패턴의증진을위해새끼벌림근활성화를통한발목외번 (eversion) 과발목굴곡을할수있도록유도한다. 일어서기동작에서가자미근의구심성수축에의한뒤꿈치딛기와같은형태로발뒤꿈치를바닥방향으로내리도록천천히유도한다. 발목관절의정렬향상을위해발뒤꿈치안쪽의팽팽한연부조직이충분히길어질수있도록유지하고발목의굴곡과신전동작의반복을촉진한다. 3 One leg standing을시킴으로써무릎신전근위에서발뒤꿈치방향으로압박을가하여 sit to stand를유도한다. III. 결과 FTSTS 에서대상자는치료전 64 초에서치료후 55 초로 9 초 2 Effects of Extensor Activation of Affected Lower Limbs on Repetitive Sit-to-Stand and Walking in Patients with Hemiplegia

Raine등은길항근으로써가자미근의길이단축과근약화는발목굴곡을제한하며, 과도한내번 (inversion) 을보인다고하였다. 25) 이와같은비효율적인발목정렬은전경골근의보상적인근활성화로인한것이라고하였다. 그리고신경계손상으로인한편마비환자에서나타나는현상으로일어서기동작시근력약화는동작수행의속도를저하시키게되어 3 지면반발력의변화를가져오게되며 21, 일어서기동작수행시정확한자세유지를하지못해무게중심의위치변화에어려움이발생하게된다. 또한뇌졸중으로인해편마비환자들은 STS를하는동안마비측다리의체중지지를자발적으로피하게되어균형잡힌자세를취하지못한다. 이를예방하기위해서 STS동안발의위치를후방에두는것이균등한체중지지와건측하지의과사용방지를위해바람직하다고보고되었다. 26) 이러한연구결과로보았을때발의내재근을활성화시켜발의접촉면을넓게하고하퇴신근의길항작용이 STS를수행하는동안에영향을미친다는것을알수있었다. 가감소되었고 TUG 에서는치료전 88초에서치료후 6초감소된 82초로향상된결과를가져왔다. 측정결과는 Table 1 그리고 Figure 1 과같다.

Key words Core stability Exercise, Trunk Control, Spine Alignment, Stroke 책임저자 Sang-Mi Jung(otjsm@hanmail.net) 논문접수일 2015 년 4 월 30 일수정접수일 2015 년 5 월 25 일게재승인일 2015 년 6 월 20 일 I. 서론매년전세계적으로약 1,500만명의뇌졸중환자가발생한다. 뇌졸중후생존자중 500만명은영구적으로운동장애 (50~ 83%), 인지장애 (50%), 언어장애 (23~36%), 심리장애 (20%) 등의합병증을가진다. 1) 이중 33~42% 는뇌졸중후 6 년간일상생활활동에도움이필요하다. 2) 뇌졸중으로인한운동장애는이동성제한, 자세조절저하및낙상발생율을높여뇌졸중환자의독립성, 사회참여, 전반적인건강상태에악영향을미친다. 3) 그러므로뇌졸중환자의재활운동초점은자세조절과관련된운동학습에따른기능회복이다. 4) 체간조절은뇌졸중후기능적결과의중요한초기예측인자이며, 신체를바로세우면서무게중심이동을원활하게 수행할수있도록해주는체간근의활동수준에의해좌우된다. 뇌졸중은근위조절에영향을미치는체간근의기능을양측모두약화시킬가능성이있다. 5) 체간조절저하와체간근의약화는뇌졸중환자에게서발견되고있지만, 고유감각과적절한체간조절의연관성은명확하지않다. 6) 체간근은다수의골격근으로이루어져있는데, 횡경막은지붕, 골반지지근은아랫부분, 척추주위근과둔근은뒷부분, 복근은앞부분으로구성된상자형태로이루어져있다. 체간근은사지의움직임이있을때나없을때나항상신체와척추를안정화시키는코르셋역할을하기때문에자세유지에중요한역할을담당한다. 7) 그러므로안정성과움직임은척추주변근육즉, 체간근의협응력에매우의존한다. 충분한안정성 은안정성과움직임사이의최적의균형을보여주는복잡한개념이고바람직한목표이다. 8) 체간안정성강화운동이뇌졸중환자의체간조절과척추정렬에미치는영향 13

NEUROTHERAPY 2015;19(2):13-21 최적의체간안정성은일상생활의기능적활동이나고위수준의과제를수행하는동안사지사용을가능하게하는균형을위하여필수적인요소이다. 또한체간의동적안정성은충분한유연성, 근력, 신경조절및고유감각을필요로한다. 8) 하지만뇌졸중환자는체감각및근긴장도저하로인해체간안정성을유지하기어렵다. 9) 신체분절이올바른정렬상태에서의고유감각은신체동작의정보를중추신경계에전달하여동작을최적의상태로만든다. 10) 체감각및근긴장도저하상태에서뇌졸중환자는불안정한환경에적응하기위해체간의비대칭적자세를형성하게된다. 편향된체간조절은불균형한근육사용, 정적또는동적균형능력저하, 다양한과제수행에어려움을초래한다. 11) 또한높은피로감과비효율적인에너지소비를증가시킨다. Garland 등 (2003) 은뇌졸중환자의자세정렬후균형과제수행시, 부정렬상태보다양측하지의근활성도가증가되었고, 에너지소모가감소했다고보고하였다. 12) 따라서뇌졸중환자의기능적재활에서이상적인목표는비대칭성을감소시키는데있다. 13) 뇌졸중환자에게일어나는신체정렬의변화를고려하지않고기능해결만을추구하는치료프로그램은환자의신체정렬의변화를심화시켜환자의기능수준을향상시키고자하는치료목표를성취하기힘들어진다. 14) 낙상은노인들에게서흔히발생하며특히뇌졸중환자는낙상의고위험군에속한다. 15) 임상적인관점에서대부분의뇌졸중환자는자세조절장애로인한낙상의두려움, 과제수행시불안감그리고위험성을많이호소한다. 16) 실생활에서환자가느끼는낙상의두려움으로인하여활동이제한된다면다양한환경에서의자세조절이어려워질것이다. 낙상의두려움으로인한활동제한은자세조절을더악화시키기때문이다. 따라서자세조절과관련된낙상에대한두려움과위험률을최소화하고, 기능적이고독립적인생활을유지하는것이매우중요하다. 17) 이는결과적으로뇌졸중환자의자세조절향상을위한다양한연구로이루어졌는데중재방법으로는측방체중이동, 공을이용한방법, 일정높이의발판에발을올리는방법, 시각적되먹임훈련및청각적되먹임훈련, 고유수용성운동조절프로그램, 트레드밀을사용한보행훈련등이있다. 18-24) 그중여러선행논문에서체간조절증진을위해체간안정성운동이효과적이라고보고되어지고있으며체간안정성운동을요통환자를대상으로실시한결과통증감소, 관절가동범위증가, 일상생활활동개선, 근력과균형능력증가가이루어진다. 25,26) 하지만아직체간안정성운동이뇌졸중환자의척추정렬에미치는영향에대한연구는아직미흡한실정이다. 따라서이논문은체간안정성강화운동이뇌졸중환자의 체간조절과척추정렬에미치는영향, 그리고체간조절과척추정렬의상관관계를대해알아보고자한다. II. 연구방법 1. 연구대상및기간본연구는천안시에소재한 D병원에서입원및통원치료를받고있는뇌졸중환자중본연구의목적에충족되는조건을가진대상자 22명 ( 연구군 13명, 대조군 9명 ) 을선정하여 2013년 8월부터 2013년 10월까지주당 3회, 10주간실시하도록하였다. 운동프로그램중재및평가측정은중추신경계치료경력 5년이상의물리치료사 2명과작업치료사 1명이시행하도록하였다. 대상자선정조건은다음과같다. 1) 뇌졸중을진단받고 6개월이상경과한자 2) 의사소통이가능한자 3) 근골격계질환을가지고있지않는자 4) 30분이상훈련이가능한사람 2. 연구방법 (1) 목안정화운동먼저경부의안정성높여주는운동을선행하며, 머리를들어배주위를본다는기분으로배에힘을넣어자세를유지시킨다. 이때목을아래로당겨경부의과도한굴곡이일어나지않게한다. 경부의다열근과굴근이동시에수축되도록유도한다. 27) (2) 수정형호흡운동환자의복부에치료사손을올려섬세하게누른다. 흡기하는동안환자가복부를들어올리게만들고, 호기하는동안배꼽이아래로향하도록이동한다. 치료사의두손은아래쪽갈비뼈로이동한다. 흡기하는동안환자의갈비뼈의확장시키고호기하는동안은좁힌다. 이운동을통한복횡근수축의물리적효과는복부용량을조절할수있는복횡근을촉진시키고호기의공기흐름의속도를증가시켜호흡에기여한다. (3) 체간의대각선운동목을굴곡시키지않는자세를정확히유지하면서머리와상부체간을바닥에서들리게하고복근이충분히수축할수있도록자세를유지하고천천히내려온다. 상부체간을들어올린후에몸을대각선으로왼손이오른쪽무릎을향하도록유도하고자세를유지하고천천히내려온다. 이때환측팔은정열이유지되도록지지해주고복근이약 14 The Effects of Core stability Strengthening Exercise for Trunk Control and Spine Alignment in Patients with Stroke

이지혜, 황병용, 정상미 해서시행하기어려운경우에도환자가스스로조절할수있도록치료사가다양한방향을유도하며최소한의도움을준다. 특히복횡근과복사근의강화를촉진하는복근할로윙운동을기초로하여체간안정성을만든다. 28) 3. 측정방법및측정도구 (1) 체간손상척도 (Trunk Impairment Scale) TIS는뇌졸중환자가가지고있는체간의운동손상에대한임상적검사방법으로서앉은자세에서의정적, 동적균형능력과체간의협응능력을측정한다. 앉은자세에서의정적균형능력 3개항목, 동적균형능력 10개항목, 체간의협응능력 4개항목으로서총 17개의항목을가지고있고최소 0점에서최고 23점까지로점수를산정할수있다. 검사자간신뢰도는 r = 0.87에서 r = 0.96이고검사자내신뢰도는 r = 0.85 에서 r = 0.99 사이로높은신뢰도와내적타당도를보이고있다. 29) TIS 는체간활동의질적인수준및치료에대한평가지침서가될수있다. 30) (2) 자세조절평가척도 (Postural Assessment Scale for Stroke) PASS는 FM-B로부터수정된측정도구로서심각한자세조절장애가있는뇌졸중환자에게도쉽게적용할수있기때문에뇌졸중환자의상태를진단할수있는유용한임상적도구이다. PASS는 3가지의기본적인자세로 ( 눕기, 앉기, 서기 ) 이루어져있으며, 자세유지능력 5항목과자세변환항목 7항목으로총 12항목으로구성되어있다. PASS는 FIM과의상관관계에서높은구성타당도 (r = 0.73) 와내적신뢰도 (k = 0.88), 검사- 재검사신뢰도 (k = 0.72) 를보였다. 31) (3) 낙상효능감척도 (Falls Efficacy Scale) FES는낙상방지와관련된자신감정도를측정하는도구로 13 개항목으로구성되어있다. 1 6번항목은기본적일상생활동작과관련된균형능력을평가하고, 8 13번항목은도구적일상생활동작과관련된균형능력을평가하며, 7번항목은이동능력을평가한다. 각항목평가시 0점은전혀두렵지않은경우, 5점은어느정도자신이있는경우, 10점은매우두려운경우이며, 숫자가클수록낙상에대한두려움이크고낙상관련자기효능감이낮은것을의미한다. 한국어로번안된 FES-S의만족할만한신뢰도와타당도가입증되었으며뇌졸중환자의낙상관련자기효능감을평가하는임상적인도구가될수있음이확인되었다. (4) 3차원척추구조분석기 (4D Formetric) 본연구는독일의뮌스턴의과대학생체공학연구소에서개발 한 3차원척추구조분석기 (4D Formetric) 를이용하여측정하였다. 형태를앞, 뒤, 아래또는위에서, 그리고시상면에서바라보는것처럼척추의모양과위치, 골반의틀어진정도등을비교적정확히측정하여분석한다. 측정방법은대상자의상의를탈의하고촬영을위한발판에올라서서등을카메라쪽을향하게하고속옷을뒤쪽만꼬리뼈가보일정도로내리게하고측정한다. 사진의분석은자동적으로이루어지는데, 먼저등표면의굴곡을분석하여대칭선을찾아낸다. 이선은척추의돌기를이은선과거의유사하다. 그다음에는등표면이분석되고이에따라 4개의해부학적인정점, 즉 VP(vertebrapromonence: C7) 과 SP(sacrum point), 2개의딤플 (PSIS) 이찾아지는데좌우의딤플의중앙을 DM이라하고이를근거로체간의기울기상태를분석한다. 이장비의특징으로는빠르고정확한측정시간 (0.04~6 초 ), 할로겐램프사용으로인한방사선피폭위험이없으며, 40 여가지이상의다양한데이터를볼수있다. 또한높은재현성과객관적데이터제공그리고측정결과를통한자세및척추측만증진단이가능하다. 정확도는표면분석에대한평균편차가 0.15mm이며, 척추만곡의평균편차가 3 이다. 32) 4. 분석방법본연구에서수집된자료는 SPSS(Statistical Package for the Social Science) version 16.0 프로그램을이용하여분석하였다. 연구대상자의일반적특성, 의학적특성을평균및표준편차와빈도분석을하였다. 두그룹간의체간조절, 낙상효능감, 척추정렬을비교분석하기위하여비모수검정방법인맨휘트니 (Mann-Whitney) U검정을이용하였으며, 체간안정성강화운동후연구군과대조군의전 후를비교분석하기위하여윌콕슨부호순위 (Wilcoxon Signed-ranks) 검정을실시하였다. 또한뇌졸중환자의체간조절, 낙상효능감, 척추정렬의상관관계를알아보기위하여스피어만 (Spearman) 상관관계분석을실시하였다. 모든자료처리의유의수준은 α=.05로하였다.

MMSE-K의평균점수는연구군이 23.8점, 대조군은 22.1점이었고, K-MBI의평균점수는연구군이 64.9점, 대조군은 66.6점으로두평가모두유의한차이가없었다. 마비측은연구군에서오른쪽 6명, 왼쪽이 7명이었으며, 대조군에서는오른쪽 4명, 왼쪽이 5명으로두군간에유의한차이는없었다 (Table 1). 2. 체간안정성강화운동전 후의체간조절비교 (1) 체간손상척도체간안정성강화운동을 10주동안실시한후, 연구군과대조군의운동전후의체간능력을 TIS를이용하여비교하였다. 연구군은체간손상척도중정적균형능력, 동적균형능력, 협응균형능력, 총점모두유의하게증가하였고 (p<.01), 대조군은유의한차이는없었다 (p<.05). 두그룹간의비교에서체간손상척도중동적및협응균형능력, 총점에서유의한차이를보였다 (p.<.01)(table 2).

NEUROTHERAPY 2015;19(2):13-21 척추분절회전각최대값은자세조절평가척도와높은상관관계를보였고 (r=-0.707), 낙상효능감과중정도상관관계를보였다 (r=0.557). 척추분절회전각최소값은체간손상척도와중정도상관관계를보였고 (r=-0.477), 자세조절평가척도와높은상관관계를보였다 (r=-0.709). 또한낙상효능감과중정도상관관계를보였다 (r=0.466). 척추측만곡최대값은자세조절평가척도와중정도상관관계를보였다 (r=-0.441). 척추정렬중에서는흉추의후만각과요추의전만각은높은상관관계를보였고 (r=0.715), 나머지는상관관계가나타나지않았다 (Table 7). IV. 고찰 균형장애는뇌졸중후일반적이며, 일상생활동작회복의지연과이동성및낙상위험증가와높은관련이있다. 33) Tyson 등은뇌졸중환자 75명을대상으로균형장애의빈도를조사한결과대상자중 83% 가균형장애를가지고있었다. 34) 이와같이균형장애는뇌졸중환자의자신감및마비측사용저하를초래하여움직임을감소시키고독립적인일상생활을불가능하게하여여러가지제한점과문제점을만든다. 하지만아직까지뇌졸중후자세조절의회복정도혹은회복속도에영향을주는최고의치료적접근에관한확실한결론은나오지않고있다. Carpes 등 (2007) 은체간안정성운동이요통환자의요통및균형에미치는영향에대해연구한결과체간안정성운동후동적균형감각에유의한차이가있었다고하였다. Suri 등은이동성에제한이있는노인을대상으로체간근과균형의연관성을알아본연구에서체간근의근력과지구력모두균형과관련성이있다고하였다. 이와같이체간근이균형에영향을미친다는것은여러연구들에서확인되었다. 35) 임상에서균형을향상시키기위해체간근강화운동은중요시되며체간정렬은체간근의회복양상을판단하는기준이된다. Bobath 역시이러한신체정렬에대한재교육을통하여뇌졸중환자의균형과보행능력을향상시키고자하였다. 뇌졸중환자의체간근을평가및측정하기위한연구들이있는데그중 McMeeken 등은초음파로측정한복횡근의두께와근전도상의근육의활성화는유의한상관관계가있다고하였다. 36) 또한 Tanaka 등은등속성장비를이용한연구에서뇌졸중환자의최대근력이일반인에비해유의하게낮았다는연구결과를보고하였다. 37) Dickstein 등은표면전극근전도를이용하여체간근을측정한결과, 뇌졸중환자의척추기립근이일 반인들에비하여유의하게약한것을발견하였다. 38) 이와같이기존연구들은체간근의근력이나두께, 활성도의변화를통해체간근및체간안정성을측정하였다. 그에비해척추정렬의변화에따른체간근및체간안정성관련연구는미비하다. 따라서본연구는체간안정성강화운동이뇌졸중환자의체간조절과척추정렬에미치는영향을알아보고체간조절과척추정렬의상관관계를알아보기위해실시하였다. Verheyden 등은뇌졸중환자 33명을대상으로체간조절향상을위해골반움직임이부가된운동을시행시킨결과, 체간손상척도가 1.01점향상되었다고보고하였다. 39) 또한 Karthikbabu 등은뇌졸중환자 30명을대상으로불안정지지면과안정된지지면에서체간안정성운동을실시한결과체간손상척도가 3.06점향상되었다고보고하였다. 42) 본연구에서도체간안정성강화운동을시행한연구군의체간손상척도가 5.92점으로향상되었다. 이는체간안정성강화운동이뇌졸중환자의체간조절향상에효과적인운동방법이라고할수있다. 요추부에서입력되는체감각정보는체간조절에중요한역할을담당한다. 척추에는극간인대, 극상인대, 황색인대, 흉요추부근막, 척주근, 요추간판, 경추후관절등의감각수용기들이있다. 이러한척추조직의넓고다양한감각수용기의분포는기능적동작수행을가능하게하는필수적인고유감각이라할수있다. Sung 등은불완전척추손상환자를대상으로 12주동안복합운동프로그램시행결과척추정렬이중립이되고복근과신근이안정화되었다고하였다. 40) 복합운동프로그램즉, 체간안정성강화운동과렛풀다운운동은하체근력및척추정렬에긍정적인효과가있다는결론은얻었다. Son 등은천장관절기능장애를가진 20대여학생을대상으로관절가동법을 8주동안시행한후골반분석과정적균형을비교하였다. 40) 그결과연구군이대조군에비해골반경사도와정적균형에서유의한차이를보였다. 결론적으로골반위치정렬은정적안정성에효과적임을증명하였다. Knott 등은청소년특발성측만증을가진환자를대상으로척추정렬을측정하여균형과측만증사이의관계에대해연구한결과유의한상관관계가없다는결론을얻었다. 41) 하지만이연구에서청소년특발성측만증환자에게측정한척추정렬은흉추의후만각과요추의전만각, 척추의앞 뒤기울기, 척추의좌 우기울기였다. 본연구에서는척추분절회전각이체간조절과높은상관관계를나타난것과차이가있다. 또한 Karthikbabu 등은뇌졸중환자의체간근의활성화에대한연구에서뇌졸중환자의체간회전은체간굴곡보다어렵다고하였다. 42) 이것은뇌졸중환자의체간회전능력저하와척추정렬중에서도척추분절회전각에대한평가가체간조절의향상을위해중요하다는것으로판단된다. 본연구결과체간안정성강화운동을시행한연구 18 The Effects of Core stability Strengthening Exercise for Trunk Control and Spine Alignment in Patients with Stroke

이지혜, 황병용, 정상미 군과일반적운동치료를시행한대조군모두척추정렬에유의한차이가없었다. 하지만체간조절과체간정렬, 특히척추분절회전각에서높은상관관계를보였다. 척추분절회전각과체간조절은서로상관관계가높다는결과를통해뇌졸중환자의체간조절을향상시키기위해서는척추정렬이중요하다고판단된다. 뇌졸중환자는중추신경계손상으로인해감각수용기의활성화가저하되어있다. 그러므로체간의감각수용기의활성화를통한체간조절의향상이뇌졸중환자에게중요하다. 본연구에서시행된체간안정성강화운동프로그램은안정성에필요한체간근만을강화시키기위해자세변화없이누운자세에서운동을시행하였다. 하지만감각수용기의활성화나기능적인측면에서이러한제한은정적선자세에서의체간정렬을바꾸기에는부족하였다. 황병용은뇌졸중환자의균형과보행능력증진을위해서는마비측하지의중둔근을포함한항중력근의근긴장도증진이필수적이며체간조절이나기능적인동작시항중력근의효율적인활동을위해서는골반과대퇴부, 그리고대퇴부와발사이의정상적인정렬이되어야한다고하였다. 23) 하지만본연구의운동프로그램이체간에만제한되어있어하지근력이나정렬에대한접근이없었다. 근활성도증가와감각수용기의활성화를위하여누운자세보다하지정렬및근력을함께고려한기능적인자세에서의운동프로그램시행이효과적일것이다. 이와같이본연구에서시행한체간안정성강화운동프로그램의제한점으로인해척추정렬에긍정적인영향을미치지못하였다고판단된다. 앞으로도척추정렬을향상시키는연구가더필요할것이며, 척추정렬을위한운동프로그램을지속적으로연구하여뇌졸중환자의척추재정렬과체간조절의연관성을알아내기위한노력이필요할것이다. 이연구는체간안정성강화운동이뇌졸중환자의체간조절과척추정렬에미치는영향을알아보기위하여실시하였다. 이연구는 2013년 8월부터 2013년 10월까지천안시에소재한 D병원에입원및통원치료를받고있는뇌졸중환자를대상으로연구군 13명과대조군 9명으로선정하여 10주동안의체간안정성강화운동프로그램이뇌졸중환자의체간조절과척추정렬에미치는영향과체간조절과척추정렬의상관관계를알아보았으며, 연구결과의요약은다음과같았다. 첫째, 체간손상척도를통한동적및협응능력에서체간안정성강화운동프로그램실시전 후유의한차이가있었으나, 대조군에서는유의한차이를볼수없어체간안정성강화를시행한연구군이체간활동의질적인수준향상을위한동적및협응능력에효과적임을알수있다. 둘째, 자세조절평가척도를통한자세유지및변환능력모두체간안정성강화운동프로그램실시전 후유의한차 이가있었으나, 대조군에서는유의한차이를볼수없어체간안정성강화를시행한연구군이자세유지및변환능력에효과적임을알수있다. 셋째, 낙상효능감척도를통한기본적일상생활및도구적일상생활동작능력에서두그룹모두전 후유의한차이가있었고, 그룹간의비교결과유의한차이가있었다. 따라서체간안정성강화를시행한연구군이자세유지및변환시낙상에대한두려움감소에효과적임을알수있다. 넷째, 척추정렬를통한흉추의후만각, 요추의전만각, 척추분절회전각, 척추측만곡에서두그룹모두전 후유의한차이가없었고, 그룹간의비교결과유의한차이가없었다. 따라서체간안정성강화프로그램만으로척추정렬이바뀌지않았다는것을알수있다. 다섯째, 체간손상척도, 자세조절평가척도, 낙상효능감은서로상관관계를보였다. 또한척추분절회전각은체간손상척도, 자세조절평가척도, 낙상효능감과의상관관계를보였고, 측만곡역시자세조절평가척도와상관관계를보였다. 척추정렬중에서도흉추후만각과요추전만각에서상관관계를보였다. 이상의결과를통해 10주간의체간안정성강화운동프로그램이뇌졸중환자의체간조절향상에효과적이었으나체간안정성강화운동프로그램만으로척추정렬이바뀌지않는다는것을알수있었다. 하지만체간조절과척추정렬에높은상관관계가있다는결과가나왔다. 이러한결과를바탕으로뇌졸중환자의체간안정성과척추정렬에효과적인운동프로그램에대한여러연구들이필요할것이고이러한노력들은뇌졸중환자의건강증진과삶의질을향상시키는데도움이될것이라사료된다. 참고문헌 1.

Methods This study targeted 30 physical therapists working in a general hospital and rehabilitation hospital. Multidimensional fatigue scale(mfs) and Pedometer(Yamas SW 650, Yamax Coporation, Tokyo, Japan) were used to measure fatigue and gait cycle. MFS consist of 19 questions and was constructed on 7 point Likertis scale to answer. Physical therapists wore Yamas Digi-walker electronic pedometer during their work hours except for the lunch time. Results In general condition and fatigue did not show significant difference all(p>.05). There is significant difference that Hospital type and House work In comparison of General condition and Gait cycle counting(p<.05). But sex, employment type, working department, educational background, exercise, alcohol availability, and past accidents, that were not significant different(p>.05). Relevance of the comparison for general status and gaitcycle counting about age, work experience, and number of patients treated had a higher negative correlation. Conclusions Physiotherapists in the work-related correlation with gaitcycle counting are considered to be higher. In the future to reflect the characteristics of physiotherapists of physical therapists work gaitcycle counting, fatigue and research on factors affecting the various aspects of management and in seeking to fatigue analysis continue to be done is needed.

이상용, 박정서, 한슬기, 이대희 많은젊은연령층일수록가사노동시간이짧았기때문이라고생각한다. 한편, 피로도는두그룹간에유의한차이가없었다 (p>.05). 또한정기적인운동에따른피로도도유의한차이가없었으며 (p>.05) 에너지소모량을대표하는보행계수와피로도간에도유의한상관관계를확인할수없었다 (p>.05). 이러한결과로보아물리치료사들의피로에대해육체적인요인은제한적이라고생각된다. 이에대해 Gandevia(1992) 는피로는단순하게일어나는것이아니라신체적인요인뿐만아니라정신적, 기타요인등이복합적으로작용한결과라고하였다. 14) 본연구에서보행계수는연령과근무경력그리고일평균환자수와다소높은음의상관관계를나타냈다 (-.70<r <-.40, p<.05). 이것은연령과근무경력그리고일평균환자수가많을수록활동량이적다는것을의미한다. 반면, 업무형태 ( 열전기치료실, 운동치료실 ) 에따른피로도나보행계수는유의한차이를확인할수없었다 (p>.05). 이러한사실로보아이것은연령과근무경력이많을수록환자를치료하는시간보다사무업무시간이상대적으로더많기때문이라고생각된다. 본연구는물리치료사의직무관련특성이피로도및보행계수에미치는영향을알아보고물리치료사들의근무조건개선및직무만족도를향상시키기위한기초자료를제공하였다는점에서의의가있다고생각한다. 그러나작업환경이나업무특성에차이가있는준종합병원이나의원에종사하는물리치료사들은대상에포함되지않았으므로전체물리치료사에적용하여일반화하기에는한계가있고, 물리치료사대상의선행연구가거의없는관계로연구결과를비교하기곤란한점이있었다. 그러므로향후물리치료사의업무특성을반영하여피로와보행계수에영향을주는요인에대해연구하고관리방안을모색하며다양한측면에서의피로도분석이지속적으로수행되는것이필요할것으로사료된다. V. 결론 본연구는물리치료사의직무관련특성들이피로도및보행계수에미치는영향을알아보고물리치료사들의근무조건개선및직무만족도를향상시키기위한기초자료를제공하고자실시하였다. 서울지역에소재하고있는병원에근무하는 21명의물리치료사를대상으로피로도를알아보기위해다차원피로척도설문조사를실시하였고보행계수를알아보기위해보행계수기를사용하여측정하였다. 본연구의결과는다음과같았다. 1. 피로도는근무형태, 업무형태, 학력, 운동유무, 가사노동정도, 과거사고경험에따라유의한차이가없었다 (p>.05). 2. 보행계수는근무형태, 가사노동정도에따라유의한차이가있었으나 (p<.05) 성별, 업무형태, 학력, 운동유무, 과거사고경 험에따라유의한차이가없었다 (p>.50) 3. 보행계수는연령, 근무경력, 일평균환자수와다소높은음의상관관계를보였으나 (-.70<r<-.40, p<.05) 신장, 체중, 근무시간, 피로도와는유의한상관관계를보이지않았다 (p>.05). 참고문헌 1.

Key Words Activities of daily living, Cerebral palsy, Massage, Range of motion 책임저자 Hyo-Lyun Roh(withtry@kangwon.ac.kr) 논문접수일 2015 년 4 월 30 일수정접수일 2015 년 5 월 25 일게재승인일 2015 년 6 월 20 일 I. 서론 뇌의발달과성장이진행되는시기에감염, 외상, 허혈, 조산등의다양한이유에의한뇌의손상이원인인뇌성마비는비정상적인근육긴장도의문제와자세및운동조절에심각한문제를지니게된다. 뇌성마비는장기적인비정상적인자세와비정상적인근긴장도의변화로인해근육의길이, 방향, 움직임의방법등에대한일련의문제를가지게된다. 뇌성마비는뇌의손상부위에따라경직형 (spasticity), 무정위운동형 (athethoid), 운동실조증 (ataxia), 혼합형 (mixed type) 으로분류되어지는데, 경직형은근육에심한긴장과수축을보이며, 운동이부자유스럽고과도하며협응이거의안된다. 1) 일반적으로경직성뇌성마비에서양마비 (diplegia), 편마비 (hemiplegia) 모두관절가동범위장애나근육단축 (shorting) 이주로발생하는것으로알려져있으므로경직형뇌성마비아동은근육의약화나경직으로인하여관절강직이강하게나타나며, 운동부전으로인한근육의단축으로상지를사용하거나하지를움직이는데어려움을갖게된다. 1) 특히하지의슬괵근 과아킬레스건의단축은경직성뇌성마비의주요한특징중하나이다. 이러한종아리근육의단축은관절가동범위의제한을가져와서비정상적인운동형태와자세이상으로인하여일상생활수행의어려움을가지게되고다양한활동을수행하는데어려움을가져와서뇌성마비아동의독립적인활동을방해하는한요인이라고할수있다. 2) 뇌성마비의치료는뇌성마비아동의보행및기능을향상시키기위한고전적인접근법들은고유수용성신경근촉진법 (Proprioceptive Neuromuscular Facilitation: PNF), 브론스트롬접근법, 신경발달접근법, 보이타법등의재활치료와약물치료, 수술적치료방법이있다. 3) 그런데, 뇌성마비의치료는집중적이고장기간의치료를요하는한편가정에서의관리도뇌성마비의재활에주요한요소이다. 그러나많은교육과가정지도에도불구하고부모들은극히전문적인물리치료법을수행하는것에큰어려움을겪게된다. 따라서, 가정에서가족들이뇌성마미아동에게쉽게적용할수있는새로운방법을모색하는것이필요한것으로보인다. 마사지는특별한의학적지식이없다하더라도일반인들이 하지의마사지적용이경직성뇌성마비아동의하지운동범위와일상생활활동에미치는영향 29

NEUROTHERAPY 2015;19(2):29-32 짧은시간동안의훈련을통하여서익힐수있는기법으로가정에서쉽게접근할수있고다양한효능을지니고있다. 마사지는손을직접상대의피부에접촉시켜어루만지거나문지르고, 두드리거나잡아당기는자극요법치료적형태로서의수세기에걸쳐서전해져오고있다. 4) 마사지처치는근육계, 신경계, 감각계, 골격계, 순환계, 면역계등의생리적효과에영향을미친다. 5) 마사지는기계적으로정맥의혈류를개선하고림프액의흐름을촉진시켜부종을감소시킬뿐만아니라, 세포막의투과성을변화시키고, 혈액순환의원활한조절을통해근육의대사기능, 근육의피로회복과근육활동도원활하게이루어질수있도록도와준다. 또한, 반복적인압력자극, 피부가자극받지않으면서자극을주면말초수용기에서척수및뇌로전달시켜근육이이완되고혈관을확장시킨다. 6) 이러한마사지를가정치료의한방법으로뇌성마비아동에게적용하여재활을향상시키는방법을모색하는것도필요한일이라고본다. 이에본연구는경직형뇌성마비아동의하지에마사지를실시한후하지의관절가동범위와일상생활동작의변화정도를살펴보고자한다. 목, 대소변조절 2개항목, 이동하기 3개항목, 장소옮기기 2 개항목, 의사소통 2개항목, 사회성 3개항목의 6개하위영역총 18개항목으로구성되어있다. 항목별로완전의존 1점에서완전독립 7점까지의 7점척도로이루어져있다.

III. 고찰 본연구는경직형뇌성마비아동의하지에마사지를실시한후하지의관절가동범위와일상생활동작의변화정도를살펴보고자하였다. 본연구에서하지에마사지를적용한결과일상생활활동의능력과무릎및발목관절의관절가동범위가증가한것으로나타났다. 뇌성마비아동은대소운동기능과같은다양한동작기술의습득의지연을보이고, 이러한지연은운동기능장애뿐만아니라일상생활의장애를유발하기도한다. 7) 본연구에서는하지마사지적용이일상생활활동증진에효과가있는것으로나타나서뇌성마비를대상으로한오미정등의연구에서경락마사지가일상생활활동, 근지구력증진시킨다고한연구와유사한결과로나타났다. 8) 뇌성마비환자들의운동기능장애는기본적인일상생활활동을영위하는데도많은장애를가져오므로, 스스로일상생활활동수행능력을높이고만족감을줄수있는지속적인중재가필요하다. 9) 함정은등은스포츠마사지가뇌성마비아동의저항과긴장, 불수의운동을크게감소시키는이완의효과가있다고하였다. 10) 본연구에서하지에적용한마사지가하지관절가동범위증진하는것으로나타났다. 라기용은마사지가뇌성마비의하지의관절가동범위를증가시킨다고하여본연구와일치하는결과를나타내었다. 11) 따라서마사지는관절의구축과변형문제를해결하는데도움을줄수있는방법이라고할수있다. Hasson 등은마사지가말초신경과자극하여혈액과림프액을순환시켜근육으로의혈류량을증가시켜주고림프의순환을증가시켜근육과관절의회복에영향을미친다고보고하였다. 12) 또한 Field 등은마사지가근육조직에직접적인압력을가해관절가동범위증진을일으킨다고하였다. 13) 본연구의결과와선행연구에따르면마사지는일상생활동작과관절가동범위를증진시킬수있으므로가정에서쉽게적용할수있는보조관리방법으로유용한것으로보인다. 따라서하지뿐만아니라다른신체부위에도마사지를적용하여그 Table 3.

Methods 30 patients who consented were randomized as two group. The control group and experimental group performed conventional physical therapy. In addition control group performed gait training using on treadmill with visual auditory biofeedback and experimental group performed gait training using on treadmill without visual auditory biofeedback. Results To find out the effect, walking characteristic by Gait Trainer 2, balance ability by BBS, FRT were three times repeatedly measured at baseline before treatment and 6 weeks after treatment. Experimental group and Control group improved more significantly after six-weeks treatment in walking speed in gait characteristic. 3After a six weeks treatment, there was no significantly difference between the two groups in gait characteristic but symmetry index(stance phase, step length) in the experimental group showed a mean difference and the positive effects higher than the control group. Control group improved more significantly after six-weeks treatment in FRT in balance ability.. After a six-week treatment, there was no significantly difference between the two groups in balance ability but BBS in the experimental group showed a mean difference and the positive effects higher than the control group. Conclusion To summarize the result of this study, it is considered that gait training using on treadmill without visual auditory biofeedback contributes to improve walking speed and FRT, gait training using on treadmill with visual auditory biofeedback contributes to improve walking speed.

NEUROTHERAPY 2015;19(2):33-40 보행의대칭성이확보되어야한다. 따라서, 편마비환자의보행훈련의목적은활보장의반복적인주기의수를증가시키는것과동시에보행의대칭성을회복하는것이다. 편마비환자의특징적인보행은일상생활과사회복귀에필수요소인이동성을저해하는요소인데, 이러한보행은보행주기와보행속도에있어느린보행을보이며, 마비측보장과비마비측보장간의활보장의차이, 마비측입각기가짧으며, 비마비측의긴유각기등이나타난다. 이에보행요소를뇌졸중환자의재활에있어제일중요한목적으로삼아야한다. 4,5) 트레드밀보행훈련은뇌졸중환자의보행문제점을개선하기위해사용되는기존의물리치료이외에시도되는다양한방법중하나이며, 서기훈련과보행패턴및근력강화, 균형등의운동조절을재인식시킨다고하였고, 독립보행이가능한치료시점의환자들에게체중지지트레드밀보행훈련은보행개선에효과가있다고하였다. 6) 또한트레드밀을이용한보행훈련은편마비환자에게마비측과비마비측의대칭적인보행을촉진하여보행에대한의욕을높일수있고지면에서의보행훈련보다효과적으로보행능력을향상시키는것으로보고되었다. 7). 뇌졸중환자의균형과기능향상을위한재활에는일반적으로보바스개념을이용한방법과고유수용성신경근촉진기법을이용한방법, 시각적피드백훈련 (visual feedback training) 및마비측체중이동등의방법이많이사용되어지고있으며, 그중시각, 전정감각, 고유감각되먹임등은마비측에정상적인감각을제공하여대칭적인보행능력을회복시키는데기여한다. 8-11) 최신의연구경향들은시각또는청각바이오피드백에의한연구가독립적으로이루어져다양한바이오피드백에대한연구효과가미미한실정이다. 따라서본연구자는뇌졸중으로인한편마비환자에게다양한시, 청각바이오피드백을이용한트레 드밀보행훈련을적용하여보행특성과균형능력의변화를알아보고자한다. 12,13) II. 연구방법 1. 연구대상및연구기간본연구는 2015년 6월 1일 7월 10일까지전남순천시소재의 P 재활병원에서뇌졸중으로인한편마비로진단받은후, 아래의연구조건을충족시켜본연구를수행하는데어려움이없는성인으로 K-MMSE 24점이상인자, 트레드밀에서 6분이상보행이가능한자, 발병한지 6개월이상인자, 하지의정형외과적질환이없는자, 과거에이와같은연구에참여한경험이없는자, 본연구의참여동의서를이해하고동의한환자 30명을선정하였다 (Table 1). 2. 측정도구 1) Gait Trainer 2 Gait Trainer 2(Biodex Medical system Inc, USA) 는연구대상자가실시간으로지면에닿아진발의모습을그림자영상을모니터를통해볼수있고실시간대상자보행속도 (meter/sec), 보행시간, 보장거리 (meter/sec), 입각기와유각기의대칭지수 (%) 를히스토그램을통해저장된정상범주값과비교할수있는장비이다. 본연구에서는시청각바이오피드백을통한보행훈련이목적이기때문에모니터와스피커를통한피드백을제공한상태에서보행훈련을하였으며, 연구전 후보행속도, 보행주기, 입각기와보장의대칭지수의변화를알아보기위해사전, 사후검사도구로사용하였다. 14) 대칭지수 ( 입각기, 보장 ) 의정량화를위해 Hsu 등의연구에사용된 Table 1.

NEUROTHERAPY 2015;19(2):33-40 지수에서 -0.79±15.35 감소하였다. 균형능력에서는 FRT에서유의한향상을보였으며, BBS에서유의한향상을보이지않았지만긍정적인효과를보였다. 이러한결과로트레드밀보행훈련은보행속도와 FRT의향상에기여하는것으로여겨지고, 시청각바이오피드백을이용한트레드밀보행훈련은보행속도의향상에기여하는것으로여겨진다. 이러한결과를통해본연구에서는시청각바이오피드백을이용한트레드밀보행훈련이편마비환자의보행속도개선에기여하고보행주기, 입각기대칭지수, 보장대칭지수에긍정적인효과를보이며균형능력향상에긍정적인효과를보인것을알수있었다. 바이오피드백과보행특성에대한최근연구에서 Druzbicki 등은그들의연구에서뇌졸중환자 50명을대상으로 2주간시각적바이오피드백의유무에따른트레드밀을사용한보행훈련에서연구군환자들은입각기의단축그리고비마비측유각기길이와사이클길이증가에상당히유의한개선을보였다고하였으며또한, 두그룹간시공간매개변수또는추가적으로평가된매개변수들에서유의한차이가없었다고하였다. 12) 조남정, 이동엽은만성뇌졸중환자 21명을대상으로실시한시각리듬자극이보행과고유수용성감각에미치는영향에대한연구에서연구군은보행속도와분속수, TUG시간이유의하게증가하였고, 고유수용성감각이유의하게증가하였다. 본연구에서는시청각바이오피드백을이용한트레드밀보행훈련을 6주간적용하여보행특성중보행속도가유의하게증가하였고, 시공간보행매개변수에서는유의한차이가없었던부분이선행연구와일치하였다. 23) 바이오피드백과균형능력에대한연구에서조남정은만성뇌졸중환자 21명을대상으로 4주간시, 청각리듬자극을적용한보행훈련을실시하여기능적팔뻗기검사와 TUG에서유의한차이가있었다고하였으며, 지상구등은뇌졸중환자 26명을대상으로전신거울앞에서운동한군과거울이없는장소에서운동한군으로나누어 6주간연구를실시하여실험군과대조군모두족저압, BBS, TUG에서연구전보다연구후에통계학적으로유의한변화를보였으며, 군간비교에서훈련후에연구군이대조군에비해유의한변화를보였다고하였다. 24,25) 김연희등은뇌졸중환자 38명을대상으로정적균형훈련프로그램과동적균형훈련프로그램을적용하여시각적바이오피드백훈련이균형능력의향상을가져올수있었다고하였다. 26) 본연구에서는시청각바이오피드백을이용하여트레드밀보행훈련을실시하였으며, 균형능력을측정하기위하여 BBS, FRT를사용하였다. BBS와 FRT에서연구군과대조군모두연구전보다연구후향상되었음을알수있었으나통계학적으로유의하지않아선행연구와는다른결과를나타내었다. 본연구의결과는편마비환자의보행능력과균형능력증진을위해서는시청각바이오피드백을이용한트레드밀보행훈련이일반트레드밀보행훈련보다더긍정적인영향을미치는것을알수있었고, 충분한치료시간과치료방법이필요한것으로사료되고, 연구대상자들의유병기간이 6개월에서 60개월까지다양하였고적은수의대상자, 짧은연구기간으로인해일반화시키는데제한점이있다. 추후이러한연구의제한점을보완하여시청각바이오피드백을이용한트레드밀보행훈련이편마비환자의보행특성과균형능력의향상에있어효과적인방법을제시할수있는연구가필요하다고사료된다. 본연구는시청각바이오피드백을이용한트레드밀보행훈련이편마비환자의보행과균형에미치는영향에대해알아보고자하였다. 연구군은일반적운동치료와시청각바이오피드백을이용한트레드밀보행훈련을실시하였고, 대조군은일반적운동치료와시청각바이오피드백이제공되지않은트레드밀보행훈련을실시하였다. 운동프로그램으로인한보행특성과균형의변화를알아보기위하여 Gait Trainer 2를이용한보행속도, 보행주기, 입각기대칭지수, 보장대칭지수의변화를측정하였고, BBS, FRT의변화를알아보기위하여 3회반복측정후평균값을구하고연구전 후에평가하여결과를비교분석하였다. 연구군과대조군의보행특성변화는운동전보다 6주후보행속도에서유의하게향상되었으며, 두그룹간의보행특성변화비교에서유의한차이가없었으나입각기대칭지수와보장대칭지수의평균차이에서연구군이대조군보다높아연구군에서긍정적인효과를보였다. 두그룹간의균형능력변화비교에서유의한차이는없었으나 BBS의평균차이에서연구군이대조군보다높아긍정적인효과를보였고, FRT의평균차이에서대조군이연구군보다높은효과를보였다. 이상의결과로볼때, 편마비환자에대한트레드밀보행훈련은보행속도향상에기여하고, 시청각바이오피드백을이용한트레드밀보행훈련은편마비환자의보행속도향상과보행주기, 입각기대칭지수, 보장대칭지수, 균형능력에긍정적인효과를보이는것으로사료된다. 따라서시청각바이오피드백을이용한트레드밀보행훈련은보행특성과균형능력향상에긍정적인운동방법으로제시할수있으며, 추후시청각바이오피드백을이용한트레드밀보행훈련을통한보행특성과균형에미치는영향을보다포괄적으로적용하기위하여다양한바이오피드백적용에따른편마비환자의보행과균형능력분석, 트레드밀보행훈련시근활성도의분석으로치료적접근이필요할것으로사료된다. 참고문헌 1.

TUG는시간과시간과두군간의상호작용에는유의한차이가있었으나 (p<.05), 두군간에는유의한차이가없었다 (p>.05)(table 8). 7. 단일과제운동군과이중과제운동군의 BBS 전 후비교이중과제훈련군과단일과제훈련군의 BBS 전-후변화는시간과두군, 시간과두군간의상호작용모두유의한차이가있었다 (p<.05)(table 9). IV. 고찰본연구는이중과제훈련과단일과제훈련이노인의균형에미치는영향을알아보고자하였다. 독립적인일상생활을하기위해서는근력과더불어균형능력또한매우중요한요소이다. 따라서노인의균형능력의감소는낙상의위험을증가시키고, 삶의질을저하시키기때문에균형능력향상은노인의삶의질향상에중요하다고할수있다. 20) 일상생활에서는이중과제, 즉여러가지과제를동시에수행하면서균형을유지하는능력이필요하다. 21) 그러나노인과같이균형이저하된사람들은이중과제조건의상황에놓여있을경우신체능력에감소가나타나고낙상과같은신체적손상의결과를초래한다. 22) 정적균형을측정하기위해 FRT와 OLST를실시하였으며, 동적균형을측정하기위해 TUG와 BBS를실시하였다. 정진희의연구에서뇌졸중환자를대상으로 8주간이중과제훈련을실시한결과저강도이중과제훈련군은운동전 21.44±2.96 cm에서운동후 27.63±2.39로, 고강도이중과제훈련군은운동전 23.75±3.41에서운동후 30.14±1.36으로 FRT에서시간에따라유의하게증가하였다. 23) 본연구에서는노인에게 4주간이중과제훈련과단일과제훈련을실시한결과 FRT에서두군모두시간에따라유의하게증가하였으나, 두군간에는유의한차이가없었다.

Methods Participants in this study are composed of 10 male college students. Rectus femoris and erector spinae was measured by using surface electromyography. SPSS(version 20) was used through normalization process for electromyography data collected before after taping. And a paired t-test was used for comparison between before and after taping treatment, and one-way repeated measures ANOVA was used for comparison between sets. Statistical significance level was fixed at.05. Results Statistically significant difference was not shown in comparing MVIC befor e after the treatment of taping applied on the rectus femoris and erector spinae. A statistically significant decrease was shown in muscle strength after taping in comparing %MVIC before after the treatment of taping applied on the rectus femoris and erector spinae. A statistically significant increase was shown in %MVIC value in comparison between sets before the treatment of taping applied on rectus femoris No statistical difference was shown in %MVIC value according to each set before the treatment of taping applied on erector spinae. No statistical difference was shown in %MVIC value according to each set after the treatment of taping applied on erector spinae. Conclusion In comparison between before and after the treatment of taping applied on rectus femoris in bodyweight half squat, the taping was efficacious, and the efficacy of taping was shown in comparison between bodyweight half squat sets as well. The efficacy of taping was shown in comparison between before and after the treatment of taping applied on erector spinae. However, the efficacy of taping was not shown in comparison between sets. Accordingly, a change in the muscle strength of erector spinae requires experimental design where it is loaded with weight or the number of sets is increased.

(2) 맨몸하프스쿼트동작가동범위는엉덩관절의높이와무릎관절의높이가동일해지는지점까지굴곡하여신전하였다. (3) 맨몸하프스쿼트동작간에시선에따라변인들에변화를가져오기때문에시선의처리는정면을바라보도록하였다 (4) 맨몸하프스쿼트를실시하는속도는 1회당 5초로맞춘메트로놈을사용하였다. (5) 표면전극의부착과맨몸하프스쿼트동작시구간설정을용이하기위해서실험대상자의하의는반바지를착용하여실험을실시하였다. (6) 맨몸하프스쿼트개수는 1세트당 100초간 3세트를실시하였다. 1세트당휴식시간은 30초로하였다. 2) 통계처리이연구에서는테이핑부착유무에따라맨몸하프스쿼트운동반복세트시근전도자료를 NORAXON사의 TeleMyo 2400T G2을통하여얻은후 SPSS Ver.20.0을이용하여통계처리하였다. 테이핑부착유무에따라서는대응표본 t-검정 (paired samples t-test) 을맨몸하프스쿼트반복세트분석은반복측정일원분산분석 (One-way repeated measures ANOVA) 을실시하였고, 모든통계적유의확률은 p<.05로설정하였다. III. 결과 20대남자대학생 10명을대상으로테이핑처치전 후맨몸하프스쿼트세트에따른넙다리곧은근과척추세움근근력변화를분석한결과는다음과같다. 1. 테이핑처치전 후 MVIC 비교테이핑처치전 후넙다리곧은근과척추세움근의 MVIC 비교결과는다음과같다 (Table 3). 넙다리곧은근의 MVIC는테이핑처치전 536.90±12.04, 테이핑처치후 551.00±14.07으로테이핑처치유무에따라통계적으로유의한차이가나타나지않았다 (p>.05). 척추세움근의 MVIC는테이핑처치전 545.10±15.07, 테이핑처치후 562.60±13.53으로테이핑처치유무에따라통계적으로유의한차이가나타나지않았다 (p>.05).
