Uncontrolled LBP may impact on the activities of daily living of the PD patients. However, study on the LBP in PD has been rarely reported. Methods: Sixty three PD patients with LBP were included, between October 00 and April 005. We investigated the clinical characteristics of LBP and response to the management prospectively. Results: Eleven male and 5 female patients were included and the mean age was 6. years. On lumbar MRI and/or X-ray, degenerative spondylosis was detected in patients, bulging discs in 30, and fractures in 9. Fourteen patients reported improvement of LBP after levodopa therapy. Young age at onset and abrmally flexed posture correlated with the responsiveness of LBP to levodopa therapy (p<0.05, respectively). These responders were more frequently experiencing motor fluctuation and dyskinesia than the n-responders (p<0.05, respectively). Conclusions: LBP in PD has diverse etiologies and clinical features. Some PD patients with LBP show response to levodopa therapy. We suggest that the prudent evaluation and proper management of LBP are important to achieve the better activities of daily living in PD patients.

있으며, 환자에게우울증도일으킬수있다는보고도있다. 9,11-1 그러나, 파킨슨병환자의허리통증에대한연구는극히드물다. 따라서본저자들은파킨슨병환자들이경험하는허리통증의임상적인양상과이를호전시키기위하여시행된치료, 레보도파치료에호전을보이는허리통증을지닌환자의특성에대하여알아보고자하였다. 대상과방법 1. 대상 00 년 10월 1일부터 005 년 월 30일까지서울아산병원신경과를방문한파킨슨병환자중허리통증으로인하여독립적인일상생활수행에어려움이있는 63명을대상으로하였다. 파킨슨병의진단은 UK Parkinson's disease society brain bank 의임상기준에근거하였으며, 13 다계통위축 (multiple system atrophy) 이나진행성핵상마비 (progressive supranuclear palsy) 등의비특이성파킨슨증후군 (atypical parkinsonism) 이의심되는환자나약물에의하여파킨슨병증상이초래된환자는제외하였다.. 방법 1) 일반적및임상적특성환자의연령, 성별, 환자의파킨슨병발병연령, 유병기간, 일일레보도파투여용량, 운동변동 (motor fluctuation) 유무, 이상운동증 (dyskinesia) 유무, modified Hoehn and Yahr 단계를병력기록지와면담을통하여조사하였다. ) 허리통증과관련한특성허리통증발생연령, 허리통증의유병기간, 허리통증의발생시기 ( 파킨슨병발병과관련한 ), 통증의양상, 자세에따른통증의변화, 약물치료, 수술치료, 물리치료, 스테로이드주사치료여부및이에대한효과, 이외의시행한기타치료, 레보도파치료후허리통증의호전유무를병력기록지와면담을통하여조사하였다. 3) 방사선학적결과허리통증으로인하여시행된요추자기공명영상 (lumbar magnetic resonance imaging; Lumbar MRI) 과요추 X선사진 (Lumbar X-ray) 을분석하였다. ) 통계및분석통계학적분석을위해 SPSS 11.5 를이용하였고, 허리통증특성의분석은기술통계를이용하였으며성별에따른허리통증, 임상적특성과레보도파치료에대한허리통증의호전의관계는 t-test와 chi-square (χ ) 를이용하였다. 레보도파치료에대한허리통증의호전에영향하는요인은로지스틱회귀분석을이용하였다.

김성렬정선주성영희김미선이명종 으므로이에대한추후연구가필요하다. 16,1 레보도파치료로허리통증이호전된그룹은호전되지않은그룹보다운동변동과이상운동증이많은것으로나타났다. 이는파킨슨병의비운동성증상인통증이운동증상처럼변동을보여통증의호전을보다잘인식한결과라고생각된다. 비운동성증상변동에대한이전연구들은통증이나이상감각증, 정좌불능 (akathisia) 등의감각증상, 과도한땀이나호흡곤란, 빈뇨등의자율신경계증상, 우울이나기분의상승 (euphoria), 환각과같은정신과적인증상이운동성증상의변동과함께변동을보일수있다고보고하였다. 이중조이거나저린감, 통증등의감각증상은 0% 의환자에게서변동을보였다. 1,19 따라서, 통증이레보도파치료에대하여변동을보이는환자는다른비운동성증상변동이있는지면밀한관찰이필요할것이다. 본연구에포함된환자중 3 명은골밀도검사 (bone densitrometry) 를시행하였다. 이중 5명은요추부위의골밀도가정상이었고 명은감소하였으며 (osteopenia) 16명에게는골다공증이나타났다. 이전의한보고는파킨슨병환자의골밀도가일반인과비교하여유의미한차이가없다고하였고, 0 파킨슨병없이만성허리통증을지닌환자를대상으로한다른보고에서는허리통증이있는환자의골밀도가일반인보다낮다고하였다. 1 그러나, 만성허리통증을동반한파킨슨병환자의골밀도에관한보고는아직없으므로추후연구가필요하다. 허리통증을호전시키기위한주사치료와물리치료는각각 5%, 0% 의환자가증상호전을보였고이중 50% 의환자는그효과가수일이내로일시적이었다. 이러한치료로증상호전을보이지않는환자뿐아니라호전된일부의환자도통증호전을위하여뜸, 부황, 한약, 카이로플락틱 (chiropractic), 스포츠마사지를처방된치료와함께병행하였고, 이로인하여상당한수준의비용을소요하고있었다. 따라서, 이러한허리통증으로인한치료비용과사회적손실에대한추후연구도필요하다. 이상과같이파킨슨병환자의허리통증은다양한임상양상을지니며병변을동반하지않은일부환자의허리통증은레보도파치료에대하여호전을보일수있다. 허리통증은그자체만으로환자에게고통을안겨줄수있으며때로는증상을호전시키지못하는수술을초래할수있고, 증상의호전을보이지않는보완대체요법등으로상당한경제적인부담을안겨줄수있다. 따라서, 의료인들은파킨슨병환자의허리통증을신중하게평가하고적절히치료함으로써환자가보다나은독립적인일상생활을영위할수있도록하는것이중요하다. 마지막으로본연구의제한점은연구에포함된환자중방사선학적소견이정상이며허리통증을동반한파킨슨병환자가 3 명밖에되지않아이에대한정확한분석이이루어지지않은점이다. 또한파킨슨병이 50세이상에서호발하는퇴행성질환임을감안할때허리통증이동반되지않은환자에서도방사선학적소견이정상이아닐수있으므로방사선학적소견을해석하는데에어려움이있었다. 따라서, 본저자들은방사선학적소견이정상이며허리통증이동반된파킨슨병환자에대한추후연구를제언하는바이다.
