Objective: Eversion of the foot is created with internal rotation of the shank, and inversion of the foot is created with external rotation of the shank. The purpose of the study was to investigate the effect of continuous changes in the angle of the subtalar joint on lower extremity alignments. Design: Cross-sectional study. Methods: Seventeen healthy young adult subjects recruited. The subjects were asked to stand up in a natural standing position on a footplate with eye open and equal weight on each foot for 10s in two different conditions: The right subtalar joint was everted continuously $0^{\circ}-20^{\circ}$ and in separate segments of $0^{\circ}$, $5^{\circ}$, $10^{\circ}$, $15^{\circ}$, $20^{\circ}$. The averages of three trials were used. The observation of the changes in the lower extremity was performed with the use of 3-dimensional motion analysis. For data analysis, the SPSS 18.0 software using paired t-test and repeated measures analysis of variance (ANOVA) was applied. Results: The angle was significantly increased at the horizontal rotation angle of the shank, thigh, and ankle without anterior rotation of the pelvis (p<0.05). The maximum horizontal rotation angle at the thigh on $20^{\circ}$ was $-4.52^{\circ}$ in static, and $-3.10^{\circ}$ in the dynamic conditions compared to $0^{\circ}$. Conclusions: Increased unilateral foot pronation, thigh, shank, ankle horizontal rotation variance was significantly effective. The observation of the changes in foot abduction with the use of a 3-dimensional motion analysis augmented in predicting the angle values of each segment of the lower extremity. In further studies, a comparison of the right and left subtalar joints need to be investigated.

Objective : The purpose of this study was to investigate the characteristics of Gam-ki (double-arm winding) depending on the emotion being expressed. Gam-ki is one of the basic movements of Korean traditional dance. Method : We selected three Korean traditional dancers who belong to National Dance Company of Korea. They were asked to express four different emotions (anger, joy, sadness, and neutral) while performing Gam-ki. We analyzed elapsed time and time ratio, size of movement, ground reaction forces and ground impulses. Results : During Gam-ki the elapsed time for each phase as well as for one cycle was longest when "sadness" was expressed then followed by "neutral" and then "angry" and "joy." Except for the ankle in/eversion, the ROMs of the lower limb joints seem not to be an emotion-characteristic factor. The ROMs of the upper limb joints were largest when "anger" was expressed. Neck rotation is associated with expressing negative emotions ("angry" and "sadness"). For medial-lateral GRF "angry"> "joy" > "neutral" > "sadness" was in order. Therefore, it can be regarded as a factor indicating the activity of the emotion.

Objective: This study investigated the different in isokinetic peak strength of the knee joint, and kinetics and kinematics in drop landing pattern of lower limb between the patellofemoral pain syndrome (PFPS) patients and normal. Method: 30 adult females were divided into the PFPS (age: 23.13±2.77 yrs; height: 160.97±3.79 cm, weight: 51.19±4.86 kg) and normal group (age: 22.80±2.54 yrs, height: 164.40±5.77 cm, weight: 56.14±8.16 kg), with 15 subjects in each group. To examine the knee isokinetic peak strength, kinematics and kinetics in peak vertical ground reaction force during drop landing. Results: The knee peak torque (Nm) and relative strength (%) were significantly weaker PFPS group than normal group. In addition, PFPS group had significantly greater hip flexion angle (°) than normal group. Moreover, normal group had significantly greater moment of hip abduction, hip internal rotation, and left ankle eversion than PFPS group, and PFPS group had significantly greater moment of knee internal rotation. Finally, there was significant differences between the groups at anteroposterior center of pressure. Conclusion: The PFPS patients had weakened knee strength, and which can result in an unstable landing pattern and cause of more stress in the knee joints despite to effort of reduce vertical ground reaction force.

Purpose: This study evaluated the clinical results of surgical treatment with minimally invasive plate osteosynthesis for treating displaced intra-articular fractures of the calcaneus in comparison with conventional lateral extensile approach plate osteosynthesis. Materials and Methods: Of 79 cases of Sanders type II or III calcaneus fractures, 15 cases treated with the minimally invasive calcaneal plate (group M) and 64 cases treated with lateral extensile approach calcaneal plate (group E) were identified. After successful propensity score matching considering age, sex, diabetes mellitus history, and Sanders type (1:3 ratio), 15 cases (group M) and 45 cases (group E) were matched and the demographic, radiologic, and clinical outcomes were compared between the two groups. Results: The median time of surgery from injury was 2.0 days in group M and 6.0 days in group E (p=0.014). At the six months follow-up, group M showed results comparable with those of group E in radiographic outcomes. In the clinical outcomes, group M showed better postoperative American Orthopaedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS) scores than did group E (p=0.001, p=0.008). A greater range of subtalar motion was achieved at the six months follow-up in group M (inversion 20.0° vs. 10.0°, p=0.002; eversion 10.0° vs. 5.0°, p=0.025). Although there were no significant differences in complications between the two groups (1 [6.7%] vs. 7 [15.6%], group M vs. group E; p=0.661), there was only one sural nerve injury and no wound dehiscence and deep infection in group M. Conclusion: Minimally invasive plate osteosynthesis showed superior clinical outcomes compared with that of the conventional lateral extensile approach plate osteosynthesis in Sanders type II or III calcaneus fractures. We suggest applying minimally invasive plate osteosynthesis in Sanders type II or III calcaneus fractures.

목 적: 후족부의 병리학적 상태의 치료와 평가를 위해서는 관상면에서 종골과 경골이 연관된 배열상태의 정확한 평가가 필수적이다. 이전의 방사선학적 검사인 발과 발목의 전후방향, 측방향, 사방향 촬영과 종골 축방향 촬영 등의 X-선 촬영상은 관상면에서 종골과 경골이 연관된 배열상태를 증명하지 못했다. 이에 본 연구에서는 후족부 관상면 배열영상(hindfoot coronal alignment view)을 새롭게 소개하고자 한다. 검사방법 : 1) 양쪽 발을 지탱할 수 있는 방사선투과성의 스탠드형 보조기구를 제작한다. 2) 양측 발은 weight-bearing position이 되게 한다. 3) 각각의 발의 위치는 발의 종축이 보조기구 판과 수직이 되도록 자세를 유지한다. 4) silhouette tracing: 발뒷꿈치 outline과 둘째 발가락이 일직선상으로 지나도록 위치시킨다. 5) 중심 X-선: 발바닥 쪽을 향해 약 $15{\sim}20^{\circ}의 각도로 종골의 뒷쪽을 향해 입사한다. 결 과 : 1) 경골 축과 종골의 내측, 외측 결절의 영상이 함께 표출된다. 2) 종골이 회전되지 않아야 한다. 3) 거퇴관절강(talotibial joint space)이 함께 나타나야 한다. 결 론: CT나 MRI 영상에서도 관상면에서 후족부의 배열상태를 증명할 수 있지만, 환자의 체중이 주어지지 않기 때문에 발의 임상적인 증상을 보여주기에는 충분하지 못했다. 하지만 후족부 관상면 배열영상은 후족부의 inversion, eversion의 자세변화를 보여주고, 경골 원위부와 종골의 varus, valgus deformity의 치료를 위한 평가 자료로 좋은 검사방법이며, 비교적 자연스럽고 편안한 자세로 환자에게 큰 도움을 줄 것으로 사료된다.

Objective: Reacquisition of motor functions following stroke depends on interhemispheric neural connections. The intervention highlighted in the present case is an insight for augmenting motor recovery by stimulating the lesioned area and adjacent areas governing the motor behaviour of an individual. The purpose of this study was to determine the changes in the motor and cognitive outcomes through multi target stimulation of cortical areas by application of multichannel transcranial direct current stimulation (M-tDCS) in a stroke survivor. Design: A case report. Methods: The patient was a participant of a trial registered with the clinical trial registry of India (CTRI/2020/01/022998). The patient was intervened with M-tDCS over the left primary motor cortex i.e. C3 point and left dorsolateral prefrontal cortex i.e. F3 point with 0.5-2 mA intensity for the period of 20 minutes. SaeboFlex-assisted task-oriented training, functional electrical stimulation over the lower extremity (LE) to elicit dorsiflexion at the ankle and eversion of the foot, and conventional physiotherapy rehabilitation including a tailored exercise program were performed. Outcome assessment was done using the Fugl-Meyer assessment scale (FMA) for the upper and lower extremity (UE and LE), Montreal Cognitive Assessment (MOCA), Wisconsin Gait Scale (WGS) and the Stroke Specific Quality of Life (SSQOL) measures. Assessment was taken at Day 0, 15 and 30 post intervention. Results: Improvement was observed in all the outcome measures i.e FMA (UE and LE), MOCA, SSQOL and WGS across the span of 4 weeks. Conclusions: M-tDCS induced improvement in motor functions of the UE and LE, gait parameters and cognitive functions of the patient.

The aim of this study was to investigate the kinematics of young adults during descent ramp climbing at different inclinations. Twenty-three subjects descended four steps at four different inclinations (level, $-8^{\circ}$, $-16^{\circ}$, $-24^{\circ}$). The 3-D kinematics were measured by a camera-based Falcon System. The data were analyzed using one-way ANOVA and the Student-Newman-Keuls test. The kinematics of descent ramp walking could be clearly distinguished from the kinematics of level walking. On a sagittal plane, the ankle joint was more plantar flexed at initial contact with $-16^{\circ}/-24^{\circ}$ inclination, was decreased in the toe off position with all inclinations (p<.001),and was decreased at maximum plantar flexion during the swing phase (p<.001). The knee joint was more flexed at initial contact with the $-24^{\circ}$ inclination (p<.001), was more flexed in the toe off position with all inclinations (p<.001), and was more flexed at minimum flexion during stance phase and at maximum flexion during swing phase with $-16^{\circ}$, $-24^{\circ}$ inclination (p<.001). The hip joint was more flexed in the toe off position with $-16^{\circ}$, $-24^{\circ}$ inclination and was deceased at maximum extension during stance phase with $-16^{\circ}$, $-24^{\circ}$ inclination (p<.05). In the frontal plane, the ankle joint was more everted at maximum eversion during stance phase with $-16^{\circ}/-24^{\circ}$ inclination (p<.01) and was decreased at maximum inversion during swing phase with $-16^{\circ}$, $-24^{\circ}$ inclination (p<.01). The knee joint was more increased at maximum varus during stance phase with $-16^{\circ}/-24^{\circ}$ inclination (p<.001). The hip joint was deceased at maximum adduction during stance phase with $-24^{\circ}$ inclination (p<.05). In a horizontal plane, only the knee joint was increased at maximum internal rotation during stance phase with $-24^{\circ}$ inclination (p<.05). In descent ramp walking, the different gait patterns occurred at an inclination of over $16^{\circ}$ on the descending ramp in the sagittal and frontal planes. These results suggest that there is a certain inclination angle or angular range where subjects do switch between level walking and descent ramp walking gait patterns.

The aim of this study was to investigate the kinematics of young adults during ascent ramp climbing at different inclinations. Twenty-three subjects ascended a four step at four different inclinations(level, $8^{\circ},\;16^{\circ},\;24^{\circ}$). The 3-D kinematics was analysed by a camera-based falcon system. Groups difference was tested with one -way ANOVA and SNK test. The different kinematic patterns of ramp ascent were analysed and compared to level walking patterns. The kinematics of ramp walking could be clearly distinguished from the kinematics of level walking. In sagittal plane, Ankle joint was more dorsiflexed at initial contact and Max. dorsiflex. during stance phase with $16^{\circ},\;24^{\circ}$ inclination and more plantarflexed at toe off and Max. plantarflex. during swing phase with $24^{\circ}$(p<.001). Knee joint was more flexed at initial contact with $16^{\circ},\;24^{\circ}$ inclination(p<.001). Hip joint was more flexed at initial contact and Max. flex. during swing phase with $16^{\circ},\;24^{\circ}$ inclination and at toe off with $24^{\circ}$(p<.001) and was more extended at Max. ext. during stance phase with $24^{\circ}$(p<.05). In frontal plane, ankle joint was more everted at Max. eversion. during stance phase with $16^{\circ},\;24^{\circ}$ inclination(p<.001). Knee joint was more increased at Max. varus. during stance phase with $16^{\circ},\;24^{\circ}$ inclination(p<.001). Hip joint was not differentiated with different inclinations. In horizontal plane, all joints were not differentiated with different inclinations. Conclusionally, In ascent ramp walking, the different gait pattern generally occurred at over $16^{\circ}$ on the ascending ramp in sagittal and frontal plane. These results suggest that there is a certain inclination angle or angular range where subjects do switch between a level walking and a ascent ramp walking gait pattern. This shows their motor control strategy between level and ascent ramp walking. Further studies are necessary to confirm and detect the ascent ramp gait patterns.

본 연구에서는 보행 시 발의 3차원 움직임에 대한 보다 정확한 동작 각도를 측정하고, 기존의 마커 방식에 의한 유선 동작 분석 시스템의 불편함을 해결하기 위해서 양상에 실제 사용 가능한 족부 진단용 우선 이동형 시스템을 개발하였다. 시스템의 주요 모듈은 3축 가속도계와 3축 자이로계로 이루어진 관성 측정 장치와 블루투스 전송 모듈로 구성되었다. 피험자는 전주 소아과 족부 임상 전문의에게 평발과 아킬레스건염을 진단 받은 소아과 환자 5명의 10족 에 대한 측정을 하였으며, 족부 전문의의 이학적 소견과 대비하여 개발 시스템에서 측정한 값과 근전도 데이터를 바탕으로 그 타당성을 평가하였다. 발목의 ROM은 외측 복사뼈에서 측정된 최대 피크와 최소 피크의 차이로 측정하였고, 이 값에 근거하여 평발이 심할수록 외번의 비율이 상대적으로 높아짐을 보였다. 근전도 측정 결과 내번근으로 작용하는 전경골근의 보상 작용으로 인해 전경골근의 근 활성도가 높게 측정되었고, 아킬레스건염에 의해 족배굴곡이 제한됨으로 인해 족저굴곡근으로 작용하는 비복근의 근 활성도가 높아짐을 보임으로서 족부 질환에 따르는 발의 비정상적인 움직임과 특정 근육의 활성 사이에 상관성이 있음을 확인 하였다.
