Methods 30 patients with chronic low back pain were recruited and randomized into two groups-the embedding acupuncture group or the placebo. At baseline, the age, height, weight, visual analogue scale (VAS), Oswestry disability index (ODI) scores were measured. And surface electromyography (SEMG) data of both erector spinae at L2, L4 level were also measured on both groups and asymmetry index (AI) were calculated. The embedding or placebo acupuncture treatment was performed on the erector spinae according to SEMG values; immediately after the first evaluation and 48 hours after the first visit. After 96 hours of intervention, the VAS, ODI score and SEMG of both erector spinae were measured again. Statistical significance was determined using the Wilcoxon signed ranks test or the Wilcoxon rank sum test. Results The mean VAS, ODI score after treatment was decreased significantly compared with baseline on both groups. And the VAS, ODI score and AI of the embedding acupuncture group was more decreased significantly than the placebo (p<0.05). Conclusions The results suggest that embedding acupuncture for chronic low back pain patients was effective on the VAS pain score, ODI score and AI of the erector spinae. (J Korean Med Rehab 2015;25(4): ) Key words Low back pain, Needle embedding acupuncture, Visual analogue scale, Oswestry disability index, Surface electromyography, Asymmetry index 서론»»» 2014년 10월보건복지부의실태조사에따르면허리통증은한방의료기관에내원하는질병의 14.3% 를차지 1) 하고있으며, 더불어요통의치료기전연구, 임상실험및문헌고찰등이국제적인학술지에발표되고있는등요통의한의학적치료에대한관심은더욱높아지고있는추세이다 2,3). 이러한한방치료행위중하나인매선침치료는혈위매 장요법또는약실자입요법으로도불리며, 증상의원인이되는부위에약실을삽입하여매몰시켜지속적인자극을주는치료법이다 4). 이렇게체내에매입된약실은근처부위의근육, 인대또는건등의조직을자극하고이에따른면역반응을유도하여항상성을증대시켜치료하는데 5), 약화된근육, 인대등으로인한각종질환에응용이가능하다. 매선침치료의최근국내연구동향은안면, 성형, 비만 105

Measuring surface electromyography values of the erector spinae during repetitive trunk flexion and extension. 럽게벌린자세에서위에기술한부착지점에전극을부착하고서측정이이루어졌다. 측정시연구대상자는가볍게허리를 45도구부려 5초간허리를굽히도록시킨후다시중립자세로돌아오고바로신전을 20도시킨후 5초간유지한다음다시중립자세로돌아오는과정을한주기로하였고, 총 5회씩실시하였다. 이때, 전극을통해척추세움근의전기적활동전위를구하였다 15). 측정이끝난후양측의근긴장도와근수축력을나타내는 RMS (root mean square) 값을통해비대칭분율 (asymmetry index, AI) 을계산하였다. 비대칭분율값은좌우양측의 RMS 값차이의절대값을좌우양측의 RMS 값의합으로나누어구하였다 15-17). 이때, 시술자와평가자는서로다른사람을두고, 낮은 RMS를나타내는쪽이어느쪽인지에대한사항외에는서로의사소통하지못하게함으로써평가자맹검이이루어질수있도록하였다. 3. 통계처리 통계처리는 SPSS 18.0 R for Windows를사용하였고, 각측정값들은평균 ± 표준편차 (mean±standard deviation) 로표시하였다. 대상자각군에서치료전후의통증강도, ODI 결과및좌우척추세움근의 RMS 비대칭분율의변화의유의성여부를측정하기위하여대응표본의비모수검정에이용되는 Wilcoxon signed ranks test가이용되었고, 양쪽군의치료효과차이의유의성여부를비교하기위하여독립표본의비모수검정에이용되는 Wilcoxon rank sum test를이용하였다. 통계결과 p<0.05 인경우를유의성이있는것으로간주하였다

6 유덕주 정재영 정석희 능장애점수 (oswestry disability index, ODI), 그리고표면근전도의비대칭분율 (asymmetry index, AI) 을이용한평가지표가사용되었다. 이중 VAS 와 ODI 는일반적으로요통연구에서많이사용된다. 하지만이둘은환자의주관적느낌과경험이섞여객관적인평가가부족하다는단점이있다. 그리하여기존평가방식에더하여좀더객관적인수치로확인할수있는평가를위해표면근전도를대안으로선택하였다 21). 표면근전도는근육으로부터나오는전기신호를피부에표면전극을부착하여통증없이감지하여측정하는방식이다. 따라서한개의개별근육만을평가하는침근전도방식과는다르게특정운동시반응하는모든근육군에대한기능을종합적으로측정하고수치화하여나타낼수있다. 이러한표면근전도는근골격계질환관련재활분야의평가에있어서새로운가능성을열어주고있다 23). 표면근전도의주요한결과값으로 RMS (root mean square) 와 MEF (median edge frequency) 가있다. RMS값은근육들로부터측정된전기적파형에서양수값과음수값을취하여제곱한후그평균을낸값에제곱근을하여계산하는방식 15) 으로일반적으로값이높아질수록근수축력과긴장이있음을의미한다. MEF는근육의피로도를나타내주는값 15) 으로값이낮아질수록피로도가높음을나타낸다. 이번연구에서는표면근전도의결과값중 RMS 값을이용하여진행되었는데, 양쪽의척추세움근의 RMS 값의차이가크다면양쪽의근긴장도가다름을나타내는것이고, 결국이는비특이적만성요통과연결시킬수있을것이다. 표면근전도에대한기존연구에서요통은주로표면근전도값의좌우비대칭의정도와비교가많이되었는데대표적으로요통환자에서표면근전도값을이용해좌우비대칭을도식화하여평가하는데응용할수있다고발표한연구 12) 가있었으며, 그외에요통환자들에있어표면근전도를통한복부근육의좌우비대칭이나타남을보고한문헌 24) 이있었다. 최 15) 역시이러한점을들어척추세움근기능의비대칭분율을통한임상연구 16) 를진행하였고, 본연구에서도이를바탕으로응용하였다. 본연구에서는매선침치료군과거짓매선침치료군으로나누어치료전후로통증강도, 일상생활기능장애정도와함께표면근전도상의비대칭분율을조사하였다. 세가지의평가결과모두매선침치료군에서치료전보다 치료후에유의한감소를확인할수있었으며, 군간비교에서도매선침치료군이거짓매선침치료군에비해더유의한감소가나타난것으로확인되었다. 또한연구결과를살펴보면거짓매선침치료군에서도치료전보다치료후에 VAS, ODI의유의한감소효과가나타났는데이는크게두가지관점에서해석해볼수있다. 첫째로거짓매선침치료에있어서도눈가림을위한단자가시행되었기때문에이에의한위약효과가나타난것으로생각되고, 둘째로는단자로인한근육과근막자극으로실제로어느정도의효과가났을가능성을생각해볼수있었다. 실제로이두가지원인이같이작용한것으로생각되며, 다만위의첫번째요인을어느정도배제시킬수있는표면근전도분석에서는거짓매선침치료군에서치료전후로유의한효과가관찰되지않았기때문에실제단자에의한효과보다는위약효과가더크게작용한것으로판단된다. 위약효과에대해고찰해보았을때이전의일부연구 25) 에서는요통환자의침치료전후를평균 VAS 를통해분석한결과최대 65% 정도의비율로위약효과에의한통증감소가있었다고보고된반면, 본연구를 VAS 를통해살펴보았을때는약 27% 의위약효과로인한통증감소가나타났다. 이는단시간유침시키는침과는달리매선실은장기간삽입되어있어상대적으로긴시간동안근막에작용하여실제치료의효과가크게작용하였기때문으로판단된다. 또한실험군의 ODI의감소에대하여세부항목에따른고찰이이루어졌는데, 상대적으로 앉기 항목에대해서평균 1.73점의감소를보여가장큰점수의감소폭을보였다. 그리고 통증정도 나 수면 에대한항목역시평균 1.47점의큰감소폭을보였다. 따라서매선침치료를시행하였을때안에들어간약실이근육을강화시키고지지하는효과가있어조금더오래앉아있을수있게해주었고, 동시에지속적으로통증제어를해줌으로써수면의질을향상시킨다고판단된다. 이번연구로만성요통환자들에게서매선침치료는양척추세움근의비대칭분율을줄여주고, 이로써요통의정도를감소시켰다는것을확인할수있었다. 아직까지는매선침의근골격계질환에의적용이나표면근전도를이용한평가에대한연구가많이이루어져있지않은상태이다. 하지만본연구를초석으로이에대한연구가활발히진행된다면임상에서보다널리사용되면서한의학에서 110 J Korean Med Rehab 2015;25(4):

7 척추세움근매선침치료가만성요통환자에미치는효과 사용되는치료및평가에있어그지평을더욱더넓혀갈수있을것이라기대한다. 결론»»» 본연구는만성요통을주소증으로하는환자 30명을매선침치료군혹은거짓매선침치료군으로나누어 5일간총 2회의치료를실시한다음시각적상사척도 (visual analogue scale, VAS), 요통기능장애점수 (oswestry disability index, ODI) 및표면근전도값의비대칭분율 (asymmetry index, AI) 을분석한결과다음과같은결론을얻었다. 1. 시각적상사척도를이용한요통의통증강도는매선침치료군과거짓매선침치료군모두유의한감소를보였으나매선침치료군에서보다나은통증강도의개선이나타났다 (p<0.05). 2. 요통기능장애점수는매선침치료군과거짓매선침치료군모두유의한감소를보였으나매선침치료군에서보다낮은기능장애점수를보였다 (p<0.05). 3. 표면근전도를이용한양쪽척추세움근의비대칭분율은매선침치료군에서만유의한감소를보였고, 매선침치료군에서대조군보다낮은비대칭분율을보였다 (p<0.05). 이상의결과를종합하였을때, 만성요통환자에게매선침치료와거짓매선침치료모두효과가나타났지만매선침치료군이유의성있게보다나은효과를보여주었다.
