Purpose: We evaluated the efficacy of ultrasound-guided lower extremity nerve block in trauma patients. Methods: From July 2013 to April 2014, 17 patients with multiple trauma had lower extremity nerve block for immediate management of open wound in the lower extremity. We evaluated the patient satisfaction of the anesthesia and any complications related to the block. Results: During the lower extremity nerve block, incomplete nerve block occurred in one patient. This is the second case, the reason for this was the lack of technique. There was no anesthetic complications. Conclusion: Ultrasound-guided lower extremity nerve block in trauma patients is an effective anesthesia technique in the immediate management of open wound in lower extremities.

We need to study about lower extremity alignment because the structure dictates the function of lower extremity. Through lower extremity alignment assessment in static posture, we recognize abnormal structural conditions which could affect dynamic motion such as gait. To evaluate of lower extremity alignment provide so many useful information, but method of measurement is so limited. Therefore, this review will assist understanding for measurement of lower extremity alignment in static posture. From now on study about the objective measurement method must be achieved much more in physical therapy.

Purpose: The purpose of this study is to examine the effects of sit-up exercise using gym ball unit on lower extremity strength. Method: Subjects consisted of 12 G University student (Male:6/Female:6) aged 23~26 years. The experiment progressed with 2 groups according to different size gym balls. and diameter of each gym ball is 45cm / 65cm. The measurement of strength of lower extremity was taken by isokinetic exercise machine(Biodex Medical, Inc, USA) Result: The results of this study were as follow. There were not different of Peak torque and Average Power between 65cm gymball and 45cm gymball. in other words using the 45cm gym ball and 65cm gym ball sit-up exercise were both effective for strengthening of lower extremity. Conclusion: Sit-up exercise on all of less than 65cm gym ball was effective for strengthening of lower extremity, furthermore it was helpful for keeping uprighting posture also it is affect on abdominal strengthening. As a result sit-Up Exercise Using Gym Ball is effective for a person with weak lower extremity and a person need uprighting posture.

Purpose: The aim of this study was to determine the effects of isokinetic eccentric training (IET) on lower extremity muscle activation and walking velocity according to slow velocity and fast velocity of isokinetic eccentric training in stroke patients. Methods: Thirty subjects were randomly divided into three groups: experimental group I (n=10), group II (n=10), and control group III (n=10). Each group was provided intervention under three conditions, as follows: isokinetic eccentric training + slow velocity (group I), isokinetic eccentric training + fast velocity (group II), and sit to stand training (group III). The training program was conducted for eight weeks (five times per week; 30 minutes per day). Subjects were measured on lower extremity muscle (vastus lateralis, vastus medialis, gastrocnemius) activation and walking velocity. Analysis of covariance (ANCOVA) were performed for comparison of lower extremity muscle activation and walking velocity between different intervention methods. Results: Significant difference in lower extremity muscle activation and walking velocity was observed in experimental group I and group II compared with the control group III (p<0.01). Results of post-hoc analysis showed a significant in lower extremity muscle activation and walking velocity in group I compared with group II and group III. Conclusion: Findings of this study suggest that slow velocity and fast velocity using isokinetic eccentric training may have a beneficial effect on improvement of lower extremity muscle activation and walking velocity in stroke patients.

Purpose : The purpose of this study was to investigate muscle activity of affected lower extremity by unaffected lower extremity exercise and tried to examine muscle activity of affected lower extremity of hemiplegic patients were caused by stroke according to wearing single strap hemisling or non-wearing. Methods : We measured muscle activity of affected lower extremity when wearing single strap hemisling to affected lower extremity or non-wearing according to unaffected lower extremity used MP 150 Eletromyogram. Results : 1) Muscle activity of gluteus medius muscle was the highest D1 before wearing single strap hemisling. 2) Muscle activity of hamstring muscle was the highest D3 after wearing single strap hemisling. 3) Muscle activity of quadriceps muscle was the highest D5 after wearing single strap hemisling. 4) Muscle activity of tibialis anterior muscle was the highest D1 after wearing single strap hemisling. 5) Muscle activity of soleus muscle was the highest D2 before wearing single strap hemisling. Conclusion : Wearing single strap hemisling of hemiplegic patients had effect on muscle activity of gluteus medius but didn't effect gluteus medius, hamstring, quadriceps, tibialis anterior muscle and soleus muscle.

Purpose: The study examined the effects of the proprioceptive neuromuscular facilitation pattern exercise and protein intake on balance, gait ability, and lower extremity muscular strength for sarcopenia in the elderly. Methods: A total of 30 elderly people (65~74years) with sarcopenia were recruited and randomized to Group I (n=10), Group II (n=10), and Group III (n=10). Their balance ability was measured using the functional reach test. Group I performed the proprioceptive neuromuscular facilitation pattern exercise and protein intake. Group II performed the proprioceptive neuromuscular facilitation pattern exercise. Group III performed protein intake. Their gait ability was measured using the Timed Up and Go test. Lower extremity muscular strength was measured using the Five Times Sit to Stand test. Results: As a result of comparison within groups, Group I and Group II showed a significant difference in balance, gait, and lower extremity muscular strength after the experiment (p<0.05), and Group I showed a more effectively significant difference than either Group II or Group III in balance, gait, and lower extremity muscular strength before and after the experiment (p<0.05). Conclusion: This study showed that the proprioceptive neuromuscular facilitation patterns exercise and protein intake was effective in balance, gait ability, and lower extremity muscular strength for sarcopenia in the elderly.

중종근무력증 환자들에게 반복신경자극검사를 시행함에 있어서 하지의 근육들의 진단적 민감성을 파악해 보기 위하여 건강한 남녀 20명과 영남대학교 의과대학 부속병원 신경과에 중증근무력증의 특징적인 증상을 주소로 내훤한 grade 2이상의 환자 10례를 대상으로 안윤근, 소지외전근, 척측수근굴근과 하지의 내경골근, 단지선근, 내광근에서 반복신경자극검사를 시행하여 다음과 같은 결과를 얻었다. 환자에서 반복신경자극검사에서 안면근육과 상지근육은 하지근육보다 민감도에서 높은 결과를 보여 주었고, 정상인과 중증근무력증 환자사이에서 안정기, 운동 직후, 운동 후 1분, 운동 후 3분에서의 감소성반응수치는 안면과 상지근육에서 통계적으로 유의한 차이 (P<0.01 or p<0.05)가 있었으나 하지근육에서는 유의한 차이를 보이지 않았다, 중증근무력증환자에서의 반복신경자극검사 결과 안윤근에서 20례, 척측수근굴근에서 14례, 소지외전근에서 12례에서 양성반응을 보였으며, 하지에서는 전경골근에서 4례, 단지선근에서 8례, 내광근에서 3례에서 양성반응이 나타났다. 이상의 결과로 볼 때, 중증근무력증이 의심되는 환자에게 반복신경자극검사를 시행할 경우에 안면과 상지근육에 정성소견이 보이면 하지근육에서 반복신경자극검사를 시행할 필요는 없는 것으로 생각되나, 빈도는 낮지만 하지근육애서도 양성반응을 보임에 따라서 추후에 좀 더 많은 환자에 대해서 하지근육의 반복신경자극검사를 시행해 볼 필요가 있을 것으로 생각된다.

A two-dimensional static biochemical model of lower extremity in the seated posture was developed to assess muscular activities of lower extremity required for a variety of foot pedal operations. We found that the double linear optimization method that has been used for modelling articulated body segments does no predict the forces generated by biarticular muscles reasonably, so the revised double linear optimization scheme was used to consider the synergistic effects of biarticular muscles in our model, assuming that the muscle forces are distributed proportionally based on their physiological cross sectional area. The model incorporated three rigid body se- gments with six muscles to represnet lower extremity. For the model validation, three male subjects performed the experiments in which EMG activities of six lower extremity muscles were measured. Predicted muscle forces were compare with the corresponding EMG amplitudes and it showed no statistical difference. The model being developed can be used to design and assess pedal and foot-related tool design.
