PURPOSE: The purpose of this study was to examine the immediate changes in the weight-bearing ankle dorsiflexion range of motion (ROM) and the dynamic balance in asymptomatic subjects using the modified Star Excursion Balance Test (SEBT) after ankle balance taping (ABT) and placebo ABT with kinesiology tape METHODS: A total of 23 active participants (11 men, 12 women) volunteered for this study. Ankle flexibility was assessed using the weight-bearing lunge test, and dynamic balance was assessed using the modified SEBT. Participants were asked to respond to questions regarding their perception of stability, reassurance, and confidence when performing modified SEBT. RESULTS: The weight-bearing ankle dorsiflexion ROM did not show a significant decrease after real ABT or placebo ABT compared to the ROM prior to ABT. The anterior, posterolateral, and posteromedial reach distances of SEBT did not increase significantly after real ABT or placebo ABT compared to the distances prior to ABT. However, the participants' perception of stability, reassurance, and confidence, when performing SEBT with real ABT, was increased compared to that during the control trial. CONCLUSION: This study showed that although real ABT did not immediately improve the reach distances in the 3 directions during modified SEBT, it improved the participants' perception of stability, reassurance, and confidence without decreasing weight-bearing ankle dorsiflexion ROM.

Background: Alignment of the lower limb is an important factor, influencing balance and gait in kinematics and kinetics, in patients with and without a flat arched foot. Flat arched foot are associated with the range of motion (ROM) of the hip and alignments of the knee joints, is strongly influenced. Objects: The purpose of this research was to investigate the relationship between hip joint ROM and quadriceps angle (Q-angle), by dividing them into two groups according to the presence or absence of flat feet, using a navicular drop test (NDT) and resting calcaneal stance position (RCSP). Methods: Forty elderly patients were allocated to the experimental group (flat foot group, n1=20) or the control group (non-flat group, n2=20). Universal and digital goniometer, tractograph and tape measure were used to determine the related changes in the hip ROM, Q-angle, NDT and RCSP. Results: Data were analyzed using the Pearson correlation coefficients. Active internal ROM of the hip joint (right, r=.803, p<.001), (left, r=.951, p<.001) were highly correlated with NDT, and also, was moderately correlated with Q-angle (right, r=.562, p=.019), (left, r=.757, p<.001). Passive internal ROM of the hip joint (right, r=.742, p=.001), (left, r=.922, p<.001) were highly correlated with NDT, and also, was moderately correlated with RCSP (right, r=-.530, p=.029) and with Q-angle (right, r=.710, p=.001), (left, r=.698, p=.002) in the flat foot group. However, no strong correlation among the hip ROM, NDT, RCSP and Q-angle were found in the non-flat foot group. Conclusion: This research may provide evidence of the correlations between hip internal ROM and flat foot.

Stroke is a major cause of death and long-term disability. Because muscle weakness is one of the most prominent consequences of stroke, it was considered important to determine whether exercise in order to improve muscle strength and range of motion could have an effect in limiting the learned disuse of the affected side. The purpose of the study was to identify the effects of an 8 week rehabilitation program on physical and cognitive ability in stroke patients. A total of 18 patients who were admitted to the oriental medicine unit of a K medical center in Seoul were recruited : ten for the experimental group and eight for the control group. The rehabilitation program consisted of three level's of active and passive exercises for prevention of muscle contracture and at range of motion. Muscle strength, flexibility of the upper and lower extremity, perceived balance, functional independence, depression, and quality of life for the two groups were compared at the pretest and 4 and 8 weeks after the rehabilitation program. The results are as follows : 1) When measuring muscle strengths of shoulder abduction and elbow flexion, hip flexion and knee extensor, ankle dorsi-flexor and muscle strength of knee flexor. Muscle strength of knee flexor for the experimental group was significantly higher than the comparison group at the 4 weeks. 2) Muscle strength and flexibility of the ankle dorsi -flexor for the experimental group was significantly better than for the control group at 8 weeks. 3) Functional independence, perceived balance, and Tinetti balance for the experimental group as measured at 4 and 8 weeks were better than for the control group. Also, there were changes over time in physical balance and functional ability, but there was no significant differences between the groups. 4) The experimental group showed a higher quality of life and lower depression than the control group at 8 weeks. 5) Muscle strength and flexibility of ankle dorsi -flexor were significantly changed over time and an interaction between group and time. The findings suggested that the rehabilitation program would improve the physical and psychological status of the stroke patients. Thus, the gains in actual or perceived ability to perform physical activities was marked.

It is difficult for the movement detection of an object through a camera to detect exact movement because of unnecessary noises and changes of the light. It can be recognized as a background, when there is no movement after the inflow of an object. Therefore, It is necessary to fast search algorithm for tracking and extract of object that is realtime image. In this thesis, we evaluate the difference of the input vision based on initial image and replace some pixels in process of time. When there is a big difference between background image and input image, we decide it is the point of the time of the object input and then extract boundary point of it. The extracted boundary point detects precise movement of the object by creating minimum block of it and searching block that maintaining distance. The designed and embodied system shows more than 95% accuracy in the performance test.

Purpose: Soft tissue defect can occur on the posterior aspect of the elbow after trauma or fracture fixation. To cover the defect and maintain elbow functions, various flap surgeries including latissimus dorsi muscle flap, lateral arm flap and radial forearm flap can be performed. We present the clinical results of transposition lateral arm flap for coverage of the elbow defect and discuss the cause of posterior soft tissue necrosis after fracture fixation. Materials and Methods: Two patients who had posterior soft tissue defect of the elbow after open reduction of the fractures around the elbow were treated with transposition lateral arm flap. The mean size of skin defect was 20 $cm^2$. The flap was elevated with posterior radial collateral artery pedicle and transposed to the defect area. Donor defect was covered with split thickness skin graft. The elbow was immobilized for 1 week in extended position and active range of motion was permitted. Results: All two cases of transposition lateral arm flap survived without marginal necrosis. The average range of motion of the elbow was 10~115 degrees. Mayo elbow performance score was 72 and Korean DASH score was 23. Conclusion: When elbow fractures are fixed with three simultaneous plates and screws, skin necrosis can occur on the posterior aspect of the elbow around olecranon area. If the size of skin defect is relatively small, transposition lateral arm flap is very useful option for orthopaedic surgeons without microsurgical technique.

Background: Shoulder horizontal adduction (HA) is performed in many activities of daily living. The limited range of motion (LROM) of HA is affected by the tightness of the posterior deltoid, infraspinatus, teres major, and posterior capsule of glenohumeral joint. The LROM of shoulder HA contributes to excessive scapular abduction. Objects: The aim of this study is to compare the scapular abduction distance and three-dimensional displacement of the scapula during shoulder horizontal adduction between subjects with and without the LROM of shoulder HA. Methods: 24 subjects (12 people in LROM group and 12 people in normal ROM group) participated. Subjects with less than $115^{\circ}$ of HA ROM were included in LROM group. Shoulder HA was performed 3 times for measuring scapular abduction distance and three-dimensional displacement of the scapula. Tape measure was used for measuring scapular abduction distance. Scapular abduction distance was normalized by dividing the scapular size. Polhemus Liberty was used for measuring the three-dimensional displacement of the scapula. Results: Normalized scapular abduction distance was significantly greater in LROM group than normal ROM group (p<.001). Three-dimensional displacement of the scapula during shoulder HA was greater in LROM group than normal ROM group (p<.05). Conclusion: LROM group had a greater scapular abduction and three-dimensional displacement of the scapula during shoulder HA compared to normal ROM group.

Background: The purpose of this study was to compare the effects of IASTM and static stretching techniques on ankle joint range of motion (ROM), static foot pressure. Methods: Twenty four subjects with gastrocnemius shortness participated in this study. The subjects were assigned randomly to one of two groups: The soft tissue mobilization technique (IASTM) group received intervention using a IASTM instrument for two minutes, and the stactic stretching group performed self stretching for 30 seconds, four times. The ROM of the ankle joint was measured by active ankle dorsi-flexion test, and a TPScan was utilized to collect the plantar foot pressure. This experiment was performed by two physical therapists. The significant level was set at ${\alpha}=.05$. Results: The results were as follows: 1) The ROM of the ankle joint and was significantly increased in both groups. 2) Plantar foot pressure was no significant in both groups. 3) There were no significant differences between the IASTM group and static stretching group for any variable. Conclusions: The results of this study suggest that static stretching is an effective and easy technique for restoring proper muscle length in subjects with gastrocnemius shortness. We recommend that static stretching technique be used for treat gastrocnemius shortness in clinical setting and home program.

Purpose: According to various medical publications, it is believed that epinephrine should not be injected in fingers. However numerous articles show the successful use of local anesthetic with epinephrine in the digits. Epinephrine-mixed lidocaine solution enables to maintain a bloodless field for operation and provides long duration of local anesthesia when patient was wide awake. Methods: From May 2009 to December 2009, ten patients underwent flexor tendon reconstruction with local anesthesia using epinephrine. No tourniquet was necessary. Before operation, all patients were injected with local anesthetics using 1% lidocaine 20 mL and 0.1% epinephrine 0.1 mL. Results: There was no case of digital necrosis nor gangrene in the epinephrine injection. All 10 patients actively could move the finger through a full range of motion. All procedures were performed without sedation nor tourniquet and we could obtain a good vision of operative field and patients were comfortable. The patient make his or her fingers move through a full range of active motion before the skin is closed. Phentolamine was not required to reverse the vasoconstriction in any patients. Conclusion: The assertation that epinephrine should not be injected into the fingers is clearly no longer valid. The epinephrine injection allowed the authors to adjust flexor tendon surgery without risks associated with general anesthesia. It also enables to ensure longer anesthetic duration and bloodless operative field, and prevent post operative complications. In case of flexor tendon surgery, the use of epinephrine injection is recommended because of the advantages of local anesthesia.

The objective of this study is to report the effectiveness of active postoperative rehabilitation on clavicular fracture by oriental medical interventions and to suggest the importance of proper rehabilitation after operation. A female patient, 43 years old, who had operation for right distal clavicular fracture was treated by oriental medical rehabilitation. We evaluated the consequence by checking numeric rating scale(NRS), shoulder range of motion and shoulder pain and disability index(SPADI). The pain of the patient was decreased and the shoulder range of motion was advanced. SPADI score was decreased. Postoperative-oriental medical rehabilitation can be effectively used for a patient on postoperative state of clavicular fracture. Further studies are needed to set up a rehabilitation protocol with oriental medical interventions after operation.

Purpose: To compare clinical and radiographic outcomes of between two and three Kirschner wire(K-wire) intramedullary fixation for fractures in the neck of the metacarpal bone. Methods: A single institutional retrospective review identified 28 cases of metacarpal fractures between March 2010 and August 2014. Each of the cases met the inclusion criteria for closed, extra-articular fractures of the neck of the metacarpal bone. The patient groups were divided by the number of K-wire. Outcomes were compared for range of motion of the metacarpophalangeal joint, radiographic parameters, and period until union. Results: The fractures were treated with either 2 Kirschner wire fixation (n=10) or 3 Kirschner wire fixation (n=18). The active range of motion of metacarpophalangeal joint and radiographic result showed no statistically significant difference between the two groups. The mean union period was 5.9 weeks. However, four cases suffered distal head perforation in 2 K-wire fixation group and one case in 3 K-wire fixation group. Conclusion: Multiple retrograde intramedullary Kirschner wire fixation is a good treatment of choice for fractures in the neck of the metacarpal bone. To prevent metacarpal head perforation, it is preferred to use three K-wires than two K-wires.
