The purpose of this study was to identify vital capacity (VC) in relation to the changing position of 19 patients with spinal cord injury (SCI) and 20 normal controls. Among the 19 SCI patients, there were 9 quadriplegics and 10 paraplegics. The vital capacity was measured in each subject during sitting, standing, lying, and head down position of 30 degrees. The data were analysed by the Kruskal-Wallis test, Mann-Whitney test, and Wilcoxon signed rank test. For the SCI, significant difference of VC accoring to the 4 positions between quadriplegics and paraplegics. In the control group, significant difference of VC according to the 4 positions. In 4 positions the VC of men were significantly larger than that of women between two groups. No statistical significant difference was shown in VC by the postural change between quadriplegics and paraplegics.

Patients with hemiplegia usually show different body weight distribution as compared with normal subjects. Asymmetrical posture during static stance has been identified as a common problem in patients with hemiplegia. The purpose of this study was to identify the effects of vision and visual feedback on body weight distribution while standing under three conditions: eyes-closed, eyes-open and visual feedback condition. Fourteen patients with hemiplegia participated in the study. Their body weight distribution during standing for 20 seconds was measured by Limloader. The data were analysed by repeated measure of one-way ANOVA. The weight bearing on the paretic limb in the eyes-open condition was significantly higher than that of the eyes-closed condition. The weight bearing on the parietic limb in the visual feedback condition was significantly higher than that of the eyes-open condition. These results suggest that patients with hemiplegia can improve their symmetrical stance ability using visual feedback.

The objective of this study was to identify pulmonary functional variations in relation to postural changes, lapse after changing position, and the use of abdominal band in the cervical cord injured. The subjects of this study were 19 quadriplegic patients who had been admitted to the department of the Rehabilitation Hospital, College of Medicine, Yousei University, from April, 1997 through May 3, 1997. A spiroanalyzer was used to measure pulmonary function in supine, standing, time after changing position, and recording to the position, application method, and tightness of the abdominal band. The data were analyzed by the repeated measure one-way ANOVA, and Wilcoxon signed rank test. The findings were as follows: 1. All phase of the patients' pulmonary function improved significantly in supine posture in contrast to standing (vital capacity by and expiratory reserve volume by ). 2. The longer the time lapsed from supine posture to standing, the patient's expiratory reserve volume, maximum ventilation volume, vital capacity, and forced expiratory volume increased. 3. When the patient lay in supine position, the maximum ventilation volume, vital capacity, and the forced vital capacity increased then the center line of the abdominal band was placed along iliac crest; on the other hand, when the patient was standing, placing the bottom line of the abdominal band along iliac crest increased the maximum ventilation volume, vital capacity, and forced expiratory volume. 4. In placing the abdominal band in the patients, leaving space between the top and bottom lines of the band helped increased in maximum ventilation volume, vital capacity, and forced vital capacity for patient in supine as well as in standing. 5. When placing the abdominal band to patients in supine posture, reducing the length of the band by 2.5% along the patient's waist line increased the patients' vital capacity, while reducing the length by 10% to patients in standing increased the maximum ventilation volume. The abdominal band should be placed in such a way that the bottom part of the band should be more tightly fastened while leaving enough room for a hand to be placed in between the body and the band for the top part of the hand. It should also be noted that in a supine position, the bottom line of the band should be placed along the iliac crest, while in standing, the center line should be placed along the iliac crest. The length of the band should also be reduced by 2.5% of the waist line in supine position, and in standing, the length should be reduced by 10%. It should also be noted that the pulmonary function of the patients should be measured at least 10 minutes after one position change.

Asymmetrical posture during static stance has been identified as a common problem in persons with hemiplegia. This study examined the effect of a purposeful exercise training program on symmetrical weight bearing in three adult persons with hemiplegia. Multiple baseline design was used. The intervention program, including ball throwing and catching, rolling ball catching and throwing, and Swiss ball pulling and stopping was introduced for 15 minutes each day during each intervention phase. Quantitative measurement of the weight distribution was taken with the Limloader. Visual inspection and mean of data revealed a significant improvement in symmetrical weight distribution. This result suggests that a purposeful exercise training program can be effective in helping persons with hemiplegia achieve symmetric stances.

Weight bearing training on the involved leg is impotant for ambulation and activities of daily living in ambulatory hemiplegic patients. Traditionally, physical therapists have relied on exercise therapy and subjective evaluation. The goal for this study was to measure lower extremity weight distribution in standing with ten hemiplegic pations(M:8, F:2) and to determine the traing effect on symmetrical standing posture using a "Limloader". The Limloader is a machine designed for training symmetrical weight bearing posture. The results showed that the ability to keep the center of gravity within the limits for balance was improved significantly but the ability to adjust weight bearing on the involved leg was not (p<0.05). This study demostrated that hemiplegics can improved their symmetrical weight bearing ability using sensory biofeedback.

Brain Perfusion CT는 시간적 제약을 많이 받는 허혈성 급성뇌경색 환자의 관류 상태에 대한 정보를 정확하고 신속하게 제공함으로써 적절한 치료를 하는데 유용한 촬영 기법으로 임상에서 많이 촬영되고 있다. 그러나 이런 장점에도 불구하고 수정체의 피폭선량이 아주 많다는 단점이 있다. 본 연구에서는 Brain Perfusion CT 검사 시 수정체 피폭선량을 최대한 감소시키기 위한 방법으로 Bismuth 차폐체와 Position의 변화를 통하여 수정체 피폭선량의 최소화 방안을 알아보기 위한 목적으로 본 실험을 진행하였다. 팬텀(PBU-50)을 사용하여 양쪽 수정체에 TLD(TLD-100)를 올려두고 IOML에 평행, IOML에 평행(Bismuth 차폐), SOML에 평행, SOML에 평행(Bismuth 차폐)의 총 4가지 Position으로 각각 5회씩 Brain Perfusion scan을 실시하여 수정체의 선량을 측정하였다. 그리고 각각의 Position에 따른 화질 변화를 측정하기 위해 4군데에 관심영역을 정하여 CT Number와 Noise의 변화를 측정하여 비교하였다. 측정된 선량을 일원배치 분산분석한 결과 유의확률 0.000으로 Position에 따라 수정체의 피폭선량에 차이가 있다고 나타났으며, Duncan 사후검정결과에서 IOML에 평행 scan을 기준으로 SOML에 평행 scan과 SOML에 평행 scan(Bismuth 차폐)에서 각각 89.16%, 89.66%로 수정체 선량이 많이 감소하였으며, IOML에 평행 scan(Bismuth 차폐) 에서 37.12%순으로 감소하여 나타났다. 연구 결과 피폭선량은 SOML에 평행한 scan과 Bismuth를 차폐하여 SOML에 평행한 scan이 동일하게 감쇠효과가 가장 크게 나타났다. 수정체의 등가선량 선량한도와 비교하여 IOML에 평행한 scan에서 종사자와 공중의 선량을 기준으로 비교하면 각각 39.47%, 394.73%로 나타났으나, Bismuth를 차폐하여 SOML에 평행한 scan에서 각각 4.08%, 40.8%로 현저하게 줄어 들었다. 화질평가에서 모든 영상의 CT Number와 Noise측정에서 팬텀 영상검사 평가기준에 적합하게 나타났다. Brain Perfusion CT 촬영 시 차폐체를 사용하고 수정체가 조사야에 들어오지 않도록 환자의 position을 조절하는 것이 수정체 피폭을 줄이는 가장 유용한 방법이라 사료된다.

본 연구에서는 통증제어가 거의 불가능한 급성요통 환자를 대상으로 바로 누운 자세를 할 수 없는 환자에게 불가피하게 자기공명검사를 받아야할 환자를 위해 기존촬영방법인 정상 체위 바로 누운 자세 대신 변형된 옆으로 누운 자세를 취하게 하여 기존 척추 전용 코일과 복부 전용 코일을 이용하여 요통을 경감시키고 불안정한 자세 보정과 움직임에 의한 인공물을 줄여 장시간 검사를 받는 환자에게 피로감을 감소시켜 자기공명검사의 성공률을 높이고자 한다. 평가방법으로는 영상의 질을 정성적 평가로 하였으며 결과로는 정상인 연구대상자 기존촬영방법인 바로 누운 자세의 평균 점수는 4.64점, 정상인 연구대상자 옆으로 누운 자세(A군)는 3.44점, 극심한 요통을 호소하는 비정상인 연구대상자 옆으로 누운 자세(B군)는 3.40점으로 나타났다. 결론적으로 정상인 연구대상자의 기존촬영방법인 바로 누운 자세에서 검사한 정성적인 평가는 예상대로 높게 나타났으나 정상인 연구대상자 옆으로 누운 자세와 극심한 요통을 호소하는 비정상인 연구대상자 옆으로 누운 자세로 검사한 영상의 정성적 평가는 거의 비슷하게 나타났다. 또한 극심한 요통을 호소하는 비정상인 연구대상자 옆으로 누운 자세(B군)의 영상평가에서 영상의학과 전문의의 영상판독에도 문제가 없는 것으로 나타났다. 이에 바로 누운 자세에서 검사를 진행함에 불편을 겪는 환자에게 이러한 기법이 보편화 된다면 임상에서 많이 활용될 것으로 사료된다.
