About 2-year old northern goshawk (Accipiter gentilis) which is designated as natural monument (#323-1) in Republic of Korea was rescued by a local farmer and presented with a 2-weeks history of pain, swelling, stiffness and limping. On physical examination, plantar pododermatitis and digit IV weakness were observed. Radiographic findings also showed bone lyses with soft tissue swelling in the foot. A definite diagnosis was made as stage III bumble foot after multidisciplinary approach of the patient. Bacterial culture was performed, and concurrently antibiotic susceptibility testing is determined using wound site exudates specimen. Bacterial isolates were identified as Staphylococcus aureus, known normal skin flora. Treatment was initiated with surgical incision and necrotized tissues removal. Lavage-drainage and ball bandage were applied with topical mupirocin ointment application. Doughnut shaped pad was attached on bottom of the ball bandage to reduce weight bearing. After three weeks of intensive care, the wound site completely healed but digit IV weakness remained permanently. The goshawk returned to nature after eight weeks after treatment.

The purpose of this study was to investigate the biomechanical alterations in the punching motion of 10 elderly women after 12 weeks of taekwonaerobics training. Seven infrared cameras(Qualisys MCU-240) and 2 force platforms(Kistler-9286AA) were used to acquire raw data. The results were as follows. First, the minimum joint angles of the lower limbs had a statistically significant difference between both the dorsiflexion/plantar flexion(1eft, $p=0.001^*$) and the inversion/eversion(both, $p=0.009^*$, $p=0.04^*$) from the ankle angle. There were differences in abduction/adduction(left, $p=0.04^*$) from the knee angle, as well as internal/external rotation(both, $p=0.07^*$, $p=0.02^*$) from the hip angle. Second, the maximum resultant joint moments of the lower limbs had statistically significant differences in the inversion/eversion moment from the ankle joint(both, $p=0.05^*$, $p=0.05^*$), the abduction/adduction moment(left, $p=0.08^*$) from the knee joint, and the internal/external rotation moment(right, $p=0.09^*$) from the hip joint. Third, the maximum resultant joint powers of the lower limbs had a statistically significant difference both in flexion/extension joint powers(both, $p=0.05^*$, $p=0.01^*$) and in abduction/adduction(both, $p=0.02^*$, $p=0.00^*$) from the hip joint, as well as abduction/adduction(left, $p=0.00^*$) from the knee joint, In conclusion, the elderly women were somewhat changed after 12 weeks of taekwonaerobics training.

This study investigated gait characteristics, kinematics, and kinetics in the lower extremities between two different shoe conditions (high heeled shoes (7 cm), and high heeled shoes with a total contact insert (TCI)) after lower extremity muscle fatigue. Although TCI shave been applied in high heeled shoes to increase comfort and to decrease foot pressure, no study has attempted to identify the effects of TCI in fatigue conditions. The purpose of this study was to determine the effects of walking in high heeled shoes with TCI after lower extremity muscle fatigue was induced. This study was carried out in a motion analysis laboratory at Hanseo University. A volunteer sample of 14 healthy female subjects participated. All in fatigue conditions, the subjects were divided into two groups. The muscle fatigue was induced by 40 voluntary dorsi- and plantar-flexion exercises and 40 heel-rise exercises of the dominant foot. Surface electromyography was used to confirm the localized muscle fatigue using power spectral analysis of three muscles (tibialis anterior, gastrocnemius medialis and lateralis). The results were as follows: (1) In muscle fatigue conditions, the use of TCI decreased the peak flexion angle of the hip joint significantly in the early stance phase (p<.05) and increased the peak hip flexion moment in the terminal stance phase (p<.05). (2) In muscle fatigue conditions, the application of TCI also increased peak hip power generation in the early stance phase and peak hip power absorption in the terminal stance phase (p<.05). (3) In muscle fatigue conditions, the use of TCI reduced the impact force significantly and increased the secondary peak vertical GRF. These findings suggest that the TCI may provide beneficial effects when muscle fatigue occurs for a high heeled shoe gait. Future research employing the patient population and various types of TCI materials are required to clarify the effects of TCI.

Purpose : This study shows the movements of the ankle and the foot in walking stages, and helps to diagnose and treat the problems of the ankle and the foot. The foot in human is a mean of the transportation, body support, and shock absorber. However, the slightest changes in the anatomical position can cause a significant increase of the stress and force in the ankle and the foot. The regular compressive force in the ankle of the normal person is generated by the contraction of the gastrocnemius and popliteus muscles, and transmitted to the achilles tendon. The plantar flexion about 10 degrees occurs immediately after the heel strike, getting ready for the weight acceptance. The shear force about 80 % of the body weight is generated immediately after the heel off of the mid stance phase. In those who have a problem in the ankle, the compression force at the ankle decreased to 1/3 of the body weight, and the shear force decreased, and the compressive force was reached at their maximum level earlier than the normal people. Conclusion : Analysis of the movements at the ankle and the foot in walking phase can make the effort to diagnose and treat the ankle and foot with the problems. However, the further study is necessary.

Purpose: To evaluate the results and prognosis of operative repair to acute rupture of achilles tend on associated sports injury. Materials and Methods: 21 cases were surgically treated and average follow-up period was 1 year and eight months. The forth decade was most common with $55\%$ and soccer was most common in sports with 5 cases. End-to-end suture of ruptured achilles tendon was performed, and paratendinous structure was wrapped sufficiently. Postoperatively. ankle was plantarflexed for 6 weeks with longleg cast. And then 2 weeks interval, short leg cast with equinous position was conversed to functional position. About 10 weeks after operation, ankle was recovered to right angle. Hooker scale was used to evaluate the results. Results: Compared to normal side, heel-floor distance of ruptures side was decreased 0.7 cm in average, and 0.8 cm was deceased after 20 times weight loaded dorsiflexion. Mid-calf circumference was deceased 0.3 cm, and active dorsiflexion and plantar flexion of ankle was decreased each 3 and 5degree. 16 cases showed ‘excellent’result and 5 cases showed ‘satisfactory’. There was no complication, such as re-rupture or infection at operation site. Conclusion: After end-to-end operative repair to achilles tendon, sufficient wrapping of paratendinous structure is efficient for healing and prevention of postoperative adhesion. And serial dorsiflex-ion cast change is considered to be a successful treatment for preventing residual equinus deformity.

Purpose: To evaluate the compensatory mechanism in vivo and develop the treatment guide by performing the comprehensive functional tests of the posterior cruciate ligament (PCL) deficient subjects. Material and Methods: 10 PCL deficient subjects and 10 healthy control group were evaluated. Performed functional tests were range of motion, posterior drawer test, Telos, 30$^{\circ}$ flexion wt-bearing view, KT-1000 arthrometer, gait analysis, EMG test and isokinetic tests. Results: Physical, KT-1000, Telos posterior tests showed significant differences, but 300 full weight bearing lateral view, muscle strength test revealed no difference between two groups. Less knee flexion at initial contact and reduced maximum valgus moment were observed in PCL deficient group. In vertical drop landing, PCL group had increased plantar flexion angle at initial contact. Conclusion: Compensatory mechanisms such as reduced unstable components and absorbing the maximal load of the joint were occurred after PCL insufficiency, which result in good clinical and functional outcomes. Further investigations would be needed to understand the functional adaptations of PCL deficient subjects.

Background: Ginseng has been used to manage various types of pain in folk medicine. This study characterized the effect of treatment with intrathecal ginsenosides, the active components of ginseng in a postoperative pain model. Methods: Male Sprague-Dawley rats were implanted with lumbar intrathecal catheters. An incision was made in the plantar surface of the hindpaw. Withdrawal thresholds following the application of a von Frey filament to the wound site were measured. To determine the role of the opioid or GABA receptors following treatment with the ginsenosides, naloxone, bicuculline (a $GABA_A$ receptor antagonist), and saclofen (a $GABA_B$ receptor antagonist) were administered intrathecally 10 min before the delivery of the ginsenosides and the changes of the withdrawal thresholds after application of the von Frey filament were Observed. Results: Treatment with the intrathecal ginsenosides increased the withdrawal threshold in a dose dependent manner. Pre-treatment with intrathecal naloxone reversed the antinociceptive effect of the ginsenosides. However, pre-treatment with intrathecal bicuculline and saclofen failed to have an effect on the activity of the ginsenosides. Conclusions: These results suggest that ginsenosides are effective to alleviate the postoperative pain evoked by paw incision. The opioid receptor, but not GABA receptors, may be involved in the antinociceptive action of the ginsenosides at the spinal level.

Muscle fatigue often induces deterioration of postural balance and muscle contraction, such as strength or maximal voluntary contraction(MVC). This study was to investigate the effects of transcutaneous electrical stimulation(TENS) applied to the fatigued muscles on postural imbalance and decline in muscle strength following fatigue of triceps surae. For the 4 months from March, 2010, twenty healthy subjects without vestibular disease and visual disturbance were recruited and induced muscle fatigue of triceps surea performed by repeated voluntary contraction. TENS was applied to gastocnemius immediately after development of muscle fatigue. Postural sway length, velocity and MVC were recorded under these conditions: pre-fatigue, post-fatigue, and TENS application to fatigued muscle during post-fatigue. Muscle fatigue increased postural imbalance as expressed by sway length and velocity and decreased muscle contraction(p<.05), while TENS improved the postural imbalance and MVC following muscle fatigue during stance(p<.05). The results suggested that fatigue on plantar flexor is associated with postural balance and muscle contraction, and TENS application to fatigued muscle was effective in improving postural imbalance and decline in muscle strength following muscle fatigue. TENS will be an effective method in exercise, working environment and daily life.

The purpose of this study was to investigate the body's strategy through kinematic variables of the lower extremities and ground reaction forces to maintain the club-head speed and ball accuracy despite the three stances during the golf swing. Ten male golfers who official handicap two were participate in the experiment. All subjects performed swing after maintaining the address posture according to stance conditions(square; SS, open: OS, closed: CS). Using a 3D motion analysis system and force plateform, the results were calculated with the 7-iron full swing each stance. In result, there was no difference in center of displacement, and left and right hip and knee joint angle displacement. Left ankle joint was largely plantar-flexed in OS, and right ankle joint was largely performed in CS from the address to the downswing. From address to take-back, right foot had a large left direction and the left foot had a right direction were greater in OS than in CS. Therefore, despite various stances, maintaining the same posture at impact is thought to have a positive effect on club head speed and ball direction.
