Methods: Seventeen stroke patients having problems with motor and somatosensory deficits were selected in Bobath Memorial Hospital adult rehabilitation center. he patients were divided into two groups; the sensorimotor deficit group (SMDG) and motor deficit group (MDG). Somatosensory stimulation on the UL, physical therapy and occupational therapy were carried out three times a week over a six week these treatments were performed in both group period. o compare each group, the following assessment tools were used: such as tactile detection thresholds (D), two point discrimination on the affected side (PDas), unaffected side (PDus) stereognosis (S) manual function test, hand function on the affected side (Has) and unaffected side (Hus), Postural Assessment Scale for Stroke (PASS) and Korean version Modified Barthel Index (K-MBI). Results: In the SMDG, somatosensory stimulation on the UL was statistically important for D, PDas, PDus (except for the thener), S, hand function on Has, on Hus, PASS length of displacement with foam (LDSEO), and K-MBI. In the MDG, somatosensory stimulation on the UL was important for D, PDas, PDus (except index finger) length of displacement with the eyes open, LDSEO, Has, Hus, PASS and K-MBI. In addition, there was a significant difference in the PASS between SMDG and MDG. Conclusion: Somatosensory stimulation on the UL affects the sensory, hand function, postural control and ADLs performance.

7 송보경 : 뇌졸중환자의상지체감각자극을통한감각, 손기능, 자세조절및일상생활수행력의변화 월에서 12개월사이에감각회복변화가일어났다고보고하였다. 하지만 Yekutiel 과 Guttman 26 은감각손상을동반한만성편마비 20명의환자를대상으로체계적인감각기능회복훈련을시행한결과촉각, 두점구별인식, 입체인식등의감각기능에유의한차이가있다고보고하였다. 이는연령, 손상부위및발병후기간이감각회복에중요한요소이지만체계적인감각자극이감각회복에중요한요소로작용한다고할수있다. 이는본연구에서진행한어깨와손부위의체계적인체감각자극이감각기능향상에기여하였다고여겨진다. 상지와손기능은 1차로손뻗기요소와물건조작에필요한손의쥐기, 조작요소로설명할수있다. 이러한기능요소는우선적으로시각정보와체감각정보의처리과정이필요한데특히공간내물체의위치와물체의특성의구별하는시각정보와손의접촉감각, 두점구별및입체인식은과제를정확하게수행하는데필수적인요소로설명할수있다. 27 본연구에서는뇌졸중환자를운동및감각손상유무를따라환자의감각기능및손기능에어떠한효과를알아보고자하였고, 6주간의체감각자극은접촉감지, 접촉구별및지각력증진과손의외, 내재근과어깨복합체주위근육의고유감각를활성화에중점을두었다. 이러한 6주간의치료과정은 1차적으로두치료군의접촉감지, 두점구별향상, 물체인식의감각기능이향상되었고 2차적으로마비측과비마비측의 M 및 PASS 에향상을보였다. 손의접촉감각은신체인식력과항중력기능에도작용하는데정상인을대상으로진행한연구에서선자세에서딱딱한표면에손끝접촉은신체요동을감소시키는데도움을주었다. 이는손의체감각정보가자세조절요소에있어공간내신체위치를인식하는공간인식에강력한도움요소로작용함을의미한다. 28 또한반복적인구심성정보를받은중추신경계는감각정보를조직화하여체간및신체의동작을정교하게이루게하여자세조절을가능하도록하고입력되는감각정보를통합하여중력선에대하여움직이는방향에따라신체를유지하도록인식하는신체인식력을증진시킨다. 29,0 뇌졸중으로인한편마비는체감각, 상지기능의저하뿐만아니라자세조절과관련된근활동의손상으로보행, 옷입기동작, 이동과같은과제수행및일상생활수행력에도영향을미친다. 1 Dickstein 등 2 은편마비환자의마비측광배근, 외복사근및복직근의선행성근활동의감소로인하여자세조절의어려움뿐만아니라체간의항중력기능저하로나타나며이는이차적으로어깨뼈, 어깨관절의해부학적정렬과생역학적특성의변화, 근약화로인한신경근활동변화로어깨의비효율적인동작을만든다고하였다. 따라서본 연구에참여한치료군의감각기능향상은일차적으로신체의움직임에인식하는도움요소에영향을주었을것으로사료되며특히감각운동치료군의손기능의변화는손의사용증가로이어져공간인식과체간의안정성에도움이되고감각되먹임과손기능향상을통해신체의안정성에상호작용하여 PASS 점수에도영향을주었을것으로생각된다. 4 이는연구에서의실시한상지체감각자극을통해두치료군의 PASS, 감각운동군의 LDSEO 와운동손상군의 LDEO 와 LDSEO 의유의한결과는손의감각및손기능의향상과자세조절간의연관성을설명할수있는결과라할수있다. 마지막으로신체기능중에서상지및손의기능은일상생활활동수행과작업능력을위해가장중요한부분으로설명된다. 뇌졸중으로인한상지기능의저하는대부분일상생활동작을어렵게하고체간의안정성을방해하여물체에대한뻗기, 조작의어려움을준다. 5 그리고손의기민과민첩성은일상생활활동에중요한요소로설명할수있다. 6 본연구의체감각자극은감각운동손상군과운동치료군의마비측뿐만아니라비마비측손기능에도변화를주었는데이러한결과는두치료군의일상생활수행능력에도움을주었을것으로사료된다. Lee와 Kim 7 은입원중인뇌졸중환자의일상생활활동에영향을미치는여러요인중건측상지와손기능이일상생활동작수행간에상관성이있다고하였다. 따라서뇌졸중으로인한편마비는한손의과도하고지속적인사용은민첩성을저하시키고일상생활의의존성과과제수행을어렵게한다. 7 따라서손의감각및손기능향상은과제의난이도를쉽게하고사용의빈도를증가시켜일상생활의습득을촉진하고향상시킨다. 하지만뇌졸중환자의일상생활활동수행향상을위해서는보상기술의습득능력, 지각과인지의손상유무및회복상태, 효과적인훈련프로그램등이고려되어야할사항이라고보고하였다. 8 따라서일상생활의활동력을증진하기위하여환자의여러가지요소중운동기능뿐만아니라지각기능, 인지기능및체계적인운동학습과정이고려되어야한다. 본연구는뇌졸중환자의감각손상유무로치료군을분류하여상지체감각자극이손감각, 손기능, 자세조절및일상생활수행력증진에어떠한효과가있는지를알아보고자 17 명의뇌졸중환자를두치료군으로분류하여 6주간의체감각자극을실시하였다. 감각운동손상군은접촉감지, 마비측모든부위와무지구제외한비마비의두점구별, 입체인식, M, PASS, LDSEO, K-MBI 에서유의한차이를보였고 (p<0.05), 운동손상군은접촉감지, 마비측모든부위, 엄지손가락끝을제외한비마비의두점구별, PASS, LDEO, LDSEO, K-MBI 에서 J Korean Soc Phys her 2012:24(5):
