Purpose: This study investigated the effect of plantar-flexor muscle fatigue on the force sense and joint reposition sense of ankle joints in the healthy adults. Methods: Fifteen healthy subjects (male: 9, female: 6) participated in this study. A digital dynamometer was used to measure the force sense error while a wireless motion capture device was used to measure the joint reposition sense error. To induce plantar-flexor muscle fatigue for a dominant lower extremity, the subjects were asked to perform plantar flexion until exhaustion while barefoot. The differences in force sense error and joint reposition sense error for the ankle joint were measured immediately. The Wilcoxon test was used to compare these values before and after inducing plantar-flexor muscle fatigue. Results: The force sense error and joint reposition sense error of ankle joints after inducing plantar-flexor muscle fatigue increased significantly compared to the values before inducing muscle fatigue. Conclusion: This study suggests that plantar-flexor muscle fatigue could degrade the force sense and joint reposition sense in ankle joints. In addition, it could deteriorate ankle proprioception.

The radiant floor heating system is traditional heating system in korea. Radiant floor heating is small in vertical temperature difference, air stream and radiant heat distribution is uniform. And radiant floor heating system provide thermal comfort conditions to the a resident. This study was undertaken to evaluate the physiological-subjective responses of the resident's posture change such as sitting and standing. The experimental investigations were carried out in climate chamber, and subjects were 4 college-age students in good health. The physiological response was skin temperature and subjective response was undertaken survey of TSV and CSV. The results were summarized as follows; The comfortable temperature range of plantar surface was $35.1{\sim}38.9^{\circ}C$ and buttock surface was $37.8{\sim}39.3^{\circ}C$.

신이는 전통적으로 비염 등의 치료에 사용되어 왔는데, 신이 에탄올 추출물은 그람 양성균인 Staphylococcus aureus 그람 음성균인 Pseudomonas fluorescens균 및 곰팡이균인 Aspergillus niger에 대하여 모두 항균활성을 보였으며, proteinase로 활성화된 receptor-2에 의한 흰쥐 뒷발바닥 부종모델에서 신이 에탄올 추출물을 경구투여한 경우 typsin이나 $tc-NH_2$로 유발된 발바닥 부종, 혈관투과성, myoloperoxidase 활성도에서 유의성 있는 억제율을 보여 항염증 활성이 뚜렷함을 나타냈다.

다시 강조하지만 신경관절병증의 수술 목표는 정상발을 만드는 것이 아니라 보조기 착용이 가능하고 발바닥을 이용한 체중 부하 보행이 가능하도록 하는 것이라는 것을 늘 유념하여 치료 계획을 세워야 한다. 따라서 적절한 수술 방법을 선택하기 위해서는 병의 진행 경과와 특성을 이해하여 적절한 술 전 계획을 수립하는 것이 가장 중요할 것이다.

본 연구에서는 OpenGL 프로그램으로 4족 보행로봇인 TITAN-VIII의 가상로봇을 설계한 후, 실제로봇의 관절각도, 본체 자세각을 가상로봇에 입력하고 벡터 회전과 평행이동을 이용하여 보행 중 본체를 수평으로 유지하는 제어를 10[ms]마다 행하였다. 디딤율 $\beta$를 0,5로 일정하게 하고, 주기가 1.5, 2.0, 3.0[sec]일 때 한주기당 이동거리를 0.2, 0.3[m]로 변경하여 좌우요동보행을 시키면서 가상로봇의 ZMP, 실제로봇의 ZMP 무게중심의 이동경로를 구하고 발바닥 좌표 변화와의 관계를 비교 분석하였다.

자기장 자극시스템을 통하여 순간펄스 고자기장을 손바닥과 발바닥 그리고 무릎에 인가한 후 체열진단시스템을 통하여 모세혈관을 포함한 인체의 혈관 자극에 의한 혈류개선 효과를 연구하였다. 연령별, 성별 구분을 통하여 자극 후 체열진단을 통해 공통적으로 자극부위에 온도가 상승하는 결과를 얻었으며, 자기장 자극기 코일에서 발생하는 자체 발열량을 제거하기 위해 플라스틱 재질의 성형물로 신체와의 직접적인 접촉을 차단시켰으며 일정거리를 유지하여 실험하였다. 그 결과 비접촉을 통하여 순수하게 자기장의 펄스파형이 피부에 가까운 혈관을 자극하여 내부 전자기 에너지가 피부에 온도상승을 가져온 것으로 고찰된다.

Purpose: The purpose of this study was to obtain detailed and quantified data concerning the effects of plantarflexor muscle fatigue induced in the non-paretic side on the spatial and temporal gait parameters of the bilateral lower extremities during walking in stroke patients. Methods: This study was conducted on 20 patients with chronic stroke. The load contraction fatigue test was applied to induce muscle fatigue in the non-paretic plantarflexor muscle. Step length, stride length, double support, gait velocity and cadence, and functional ambulatory profile (FAP) score in the bilateral lower extremities were measured using a gait analysis system in order to investigate changes in temporal and spatial gait parameters caused by muscle fatigue on the non-paretic side. The statistical significance of the results was evaluated using a paired t-test. Results: A review of the results for gait parameters revealed a significant increase in double support (p<0.05) and a significant decrease in step length, stride length, gait velocity and cadence, and FAP score (p<0.05). Conclusion: These results indicate that the muscle fatigue in the non-paretic side of the stroke patients also affected the paretic side, which led to a decrease in gait functions. This implies a necessity to perform exercise or training programs in a range of clinical aspects not causing muscle fatigue.

Objective: In this case report, we address the case of a 68-year-old woman with numbness in both soles due to restless legs syndrome. Methods: A patient was treated with Korean medicine including herbal medication Gyejibokryeong-hwan during 73 days as an outpatient. We evaluated the improvements of symptoms by use of the International Restless Legs Scale (IRLS) and checking subjective symptoms of patient. Results: After 73 days of Korean medicine treatment, there was improvement in patient's symptoms. IRLS score improved from 12 to 8, and subjective symptoms improved to about 30% compared to the first time. Conclusions: This study suggested that Korean medicine treatments might be effective in RLS patient recovery.

Purpose : This study was to investigate the effectiveness of ESWT and plantar fascia-specific stretching exercise vs ESWT and high-load strengthening exercise in patients with chronic plantar fasciitis. Methods : The subjects were randomized to extracorporeal shock wave therapy ( ESWT, for 3 weeks) and daily plantar-specific stretching (Group I: Stretch group) or ESWT and high-load progressive strength (Group II: Strength group) performed every second day. The main outcome measures were ultrasound, visual analogue scale (VAS), and Korean Foot Function Index (KFFI). The ultrasound (plantar fascia thickness), pain intensity I, II (the most painful of the day?, the pain when you first step in the morning?) and KFFI (functional performance) were compared between the groups. Results : No significant difference was observed between the groups in the plantar fascia thickness but pain intensity I, II was significantly lower in Group 2 than in Group 1 at only 12weeks and functional performance was also significantly increased in Group 2 compared to Group 1 at only 12 weeks. Conclusion : The high-load strengthening exercise consisting of the progressive exercise protocol, resulted in superior after 12 weeks compared with plantar-specific stretching. High-load strength exercise may aid in a quicker reduction in pain and improvements in functional performance.

Objective: The purpose of this study was to identify the effect of reduced plantar cutaneous sensation on gait kinematics during walking with and without CAI. Method: A total of 20 subjects involved in this study and ten healthy subjects and 10 CAI subjects participated underwent ice-immersion of the plantar aspect of the feet before walking test in this study. The gait kinematics were measured before and after ice-immersion. Results: We observed a before ice-immersion on plantar cutaneous sensation, CAI subject were found to reduced ankle dorsiflexion, knee external rotation, hip adduction, and internal rotation compared to control subject. After ice-immersion, CAI subjects were found to reduce knee external rotation, hip adduction. However, no significant ankle joint kinematics. Conclusion: While walking, gait pattern differences were perceived between groups with and without plantar cutaneous sensation. The results of the study may explain the abductions in the hip angle movements in CAI patients at initial contact compared to healthy subjects in the control group when plantar cutaneous sensation was reduced. A change in proximal joint kinematics may be a conservative strategy to promote normal gait patterns in CAI patients.
