Purpose: The purpose of this study was to investigate the effects of whole-body vibration stimulation on proprioception and tactile in patients with spastic cerebral palsy. Methods: This study was conducted on 9 children diagnosed with spastic cerebral palsy. Of the single case study methods, the ABAB design was employed in this study. Out of a 12-week study period, three weeks were allocated to each of two baseline periods and two intervention periods. The exercise was performed twice a week for 30 minutes. A general trunk stabilization exercise was performed during the baseline period and a trunk stabilization exercise accompanied with whole-body vibration was performed during the intervention period. Evaluation was performed five times in total: before the experiment, after baseline 1, after intervention 1, after baseline 2, and after intervention 2. To determine the effect of the exercise method, a skin sensory evaluation tool (monofilament kit) and a trunk proprioception sensor (digital dual inclinometer) were used. To compare the effects of the exercises at baseline and after intervention, an analysis of variance on repeated measures (repeated ANOVA) was performed to analyze the data. Results: The results showed that there were statistically significant increases from baseline in the means of proprioception and tactile during the intervention period with whole-body vibration (p <.05). Conclusion: Whole-body vibration can be proposed as an effective intervention method for improving the proprioception and tactile in children with spastic cerebral palsy, and this exercise method is expected to be actively used in clinical practice.

본 연구는 맞춤형 착석장치를 통한 자세지지가 뇌성마비 아동의 상지 마우스 사용 능력에 미치는 영향을 알아보고자 실시하였다. 단일대상 연구방법의 하나인 ABAB 설계를 실시하였고, 경직성 사지마비로 진단받은 13세 뇌성마비 남아가 참여하였다. 대상자의 중재 전 휠체어 앉기 자세와 자세지지를 통한 중재 자세에서 마우스 클릭을 위한 반응시간과 정확도를 비교하였다. 중재 자세는 현행 임상지침과 상지 운동을 촉진하는 것으로 밝혀진 연구결과를 참고하였고, 대상자의 전형적인 휠체어 앉기 자세에서 도수 평가 후 맞춤형 착석장치를 통해 교정하였다. 연구 결과는 기초선 자세보다 중재 자세에서 마우스 클릭을 위한 반응시간이 감소한 것으로 나타났다. 마우스클릭의 정확도는 모든 단계에서 높게 나타나 분석을 실시하지 않았다. 이는 맞춤형 착석장치를 통한 기능적인 앉기 자세가 뇌성마비 아동의 상지 마우스 사용 능력에 긍정적인 영향을 미친다는 경험적 증거를 제공한다. 향후에는 다른 장애 유형과 더 많은 대상자를 상대로 맞춤형 착석장치가 사용자의 컴퓨터 접근성 향상 등 상지 기능에 효과적이라는 결과를 일반화할 수 있는 연구가 필요하다.

The effects of token and social reinforcement on inappropriate study behaviors of nursery school children were investigated. The subjects were three nursery school boys, and the target behaviors were : 1) out-of-seat behaviors, 2) bothering other children, and 3) disruptive behaviors. The ABAB(Reversal) design was used in this experiment. It consisted of four periods : baseline, reinforcement I, reversal, and reinforcement II. During the reinforcement period, social reinforcement as well as token reinforcement was applied. In all three subjects, inappropriate study behaviors decreased during the reinforcement periods (I, II), and increased during the reversal period, showing the effects of token and social reinforcement. The subjects showed stability in three post-experimental tests, indicating that modification of inappropriate study behaviors was being maintained.

목적 : 본 연구는 편측 무시를 가진 뇌졸중 환자에게 불빛 자극을 주었을 때 편측 무시가 얼마나 완화되는지, 또 그러한 자극이 MVPT 구성 항목에 어떠한 영향을 미치는지를 알아보고자 한다. 연구방법 : 본 연구를 위하여 청주 성모병원에서 뇌졸중 진단을 받고 입원치료를 받고 있는 환자 중 왼쪽 무시가 있으면서 연구방법을 이해하고 동의한 60세 남자환자를 대상으로 하였다. 대상자의 편측 무시정도는 MVPT를 이용하여 측정하였다. 단일사례연구 방법 중 반전설계(ABAB설계)로 A는 기초선(baseline)을 설정하는 기간으로 5일 동안 동일한 시간과 장소에서 선 나누기 검사(line bisection)를 실시하고 B는 중재기간으로써 4일 동안 불빛 자극을 주기 전과 후, 각각 1회씩 선 나누기 검사를 실시한다. MVPT 구성 항목의 변화를 보기 위해 3회 실시 하였다. 결과 : 기초선 기간 중 선 나누기 검사의 평균값은 12.19mm 불빛 자극 후의 평균값은 9.15mm로 24%의 오류감소를 보였다. 두 번째 치료기간 중 불빛자극 후의 평균값은 6.37mm로 처음 치료기간보다 43%의 오류감소를 보였다. MVPT 점수는 반응 행동이 13개에서 18개로 증가하였고, 수행시간은 16.14초에서 7.52초로 향상되었다. 결론 : 본 연구 결과는 편측 무시를 가진 뇌졸중 환자에게 불빛 자극이 편측 무시를 감소시키는 효과가 있음을 알 수 있고 치료기간이 중첩되어 일어날수록 치료효과도 좋아 진다는 것을 알 수 있다. 또 불빛 자극이 MVPT 수행 시간 향상에 영향을 준 것을 알 수 있었다.

Objective: This study is designed to examine how an application of a kinesio taping to the foot drop of a hemiplegic patient affects the functional recovery of a gait. Method: The patient was a man with left hemiplegia of about 11 months' duration. a single subject design (ABAB design) was used to investigate the timing difference at a stance phase between an unaffected side and an affected side in the gait ability of the hemiplegic patient by using the kinesio taping. The study was divided into four phase: an initial base-line, an experimental, a second base-line, and second experimental phase. Result: The timing difference at a stance phase between an unaffected side and an affected side in the gait was decreased in the case of the affected side by following the result of applying the kinesio taping to a lower extremity. Conclusion: The kinesio taping applied to the foot drop of a hemiplegic patient affects the improvement of the gait ability.

This study was to investigate the effects of a functional electrical stimulation (FES) on temporal parameters (stride length, step width and cadence) of gait patterns in a patient with right hemiparesis. A single-subject reversal (ABAB) design was used. The subject was a 25-year-old male who had foot drop and circumduction gait pattern. An ink foot-print method was used to assess the temporal parameters of gait between the baseline phase and the intervention phase. FES was applied at 8 m walkway, three times a week for 5 weeks. The results showed that stride length was increased by 4.04 cm and that step width was decreased by 3.93 cm in the intervention phase. There was no difference in cadence between the baseline phase and intervention phase.

Objectives : This study was designed to evaluate the effect of moving cupping therapy on the edema of paretic hand in stroke patients. Methods : The subjects were stroke patients with flaccid hemiplegia. Each subject's routine therapy program was maintained throughout single subject ABAB design. During the first week, baseline data were gathered. During the second and fourth week, intervention was provided(total 20minutes of moving cupping therapy, from contralateral to ipsilateral, distal to proximal). During third and fifth week, data were gathered with treatment withdrawn. Edema was measured with hand volumeter and measuring tape. Basically Bayesian analysis was performed using WinBUGS(ver. 1.4), for addition, visual graph and mean score were also presented for comparison between treatment(moving cupping therapy) and non-treatment. Results : The visual graph and mean score showed decrease in edema during the treatment weeks. Overall decrease in edema by moving cupping therapy was verified significantly by using Bayesian ana-lysis(95% credibility intervals). Conclusions : This study suggests that moving cupping therapy could be applicable for reducing post-stroke hand edema. Further research would be needed to establish guidelines for use.

Objective : The experiment consists of measuring functional grasp ability of a child suffering from sensory defense disability of the hands as the child is treated with sensory integration therapy. Methods : We treated two-year-old child with developmental disability to set up the reversal design(ABAB design). We used treatment equipments, free activities, and toys for sensory integration therapy. Results : A child's functional grasp ability did not show anything before the sensory integration therapy, however, after the sensory integration was applied during the first treatment(Treatment 1), the five minutes before the treatment, it averaged 1.87 times(ranges=0 to 5 times), the five minutes after the treatment, it averaged 1.25 times(ranges=0 to 8 times) showing an increased. After ending the sensory integration therapy, the functional grasp ability averaged 2.5 times before the therapy and 4 times after the therapy, which showed a totally different tendency, when we reapplied the treatment during the second treatment(Treatment 2), it averaged 2.4 times(ranges=1 to 4 times) before the treatment, and it averaged 5.3 times(ranges=4 to 6 times) after the treatment, which showed a big improvement. Conclusion : The sensory integration therapy brought an increase in functional grasp ability along with improvement in daily life functions of the child. For this result, there should be more research to see more effects and results to help those in need.

12세로 추정된 시설아동의 2년간 지속된 구토행위를 행동치료 방법을 사용하여 치료하였다. 이 아동의 구토행위 형태는 바닥에 음식을 토해 낸 후 $2{\sim}3$ 차례에 걸쳐 토한 음식을 다시 먹는 것이었다. 치료 방법으로 일단 토해 낸 음식을 다시 먹지 못하도록 하기 위해 음식을 토할 때마다 즉시 토한 음식을 치웠다. 일단 위에 들어간 음식을 역류시켜 바닥에 토하지는 않았지만 입안에서 씹을때는 입을 강제로 벌려 입안의 음식물을 제거하였다. 치료는 약 3주간 지속되었는데 식사 후 2시간 30분동안 치료전에는 평균 46회($범위=30{\sim}62회$)토했고 치료 후에는 평균 1.12회($범위=0{\sim}10회$)로 감소하였다. 치료 종료 후 10개월이 지난 뒤에도 아동의 구토행위는 재발되지 않았다. 따라서 토하는 행위를 강화시키는 요인인 '토해낸 음식을 다시 먹는 기회'를 박탈한 본 연구의 치료방법은 구토행위의 치료에 매우 효과가 높은 것으로 나타났다.
