Golf is low demanded activity and becoming more popular. But it often occur problems in back, shoulder, elbow and wrist. Golf injuries in professional golfer are related overuse and frequency, while in amateur are related wrong swing technique. Also muscle activities in swing are different between professional and amateur. We report partial tear of pronator teres in middle aged amateur golfer with literatures.

The stress fracture of the femoral neck is an uncommon injury and delay in diagnosis occurs occasionally. It is generally classified as the compression type and the tension type. The compression type fracture of the femoral neck is stable, and could be treated nonoperatively. Tension type fracture is potentially unstable, and could require operative stabilization. The displacement of the femoral neck stress fractures has potential complications such as osteonecrosis of femoral head, malunion and nonunion. We have experienced two cases of compression type fractures that progressed to entire femoral neck despite conservative treatment with avoidance of weight bearing. These two cases shows even compression type of femoral neck fracture could further progress to entire femoral neck after conservative treatment, which could require operative treatment.

Lateral ankle sprains are one of the most common injuries to the lower extremity. Most of them well respond to conservative treatments. However, simultaneous peroneal nerve injuries may occur rarely following lateral ankle ligamentous injuries. We report a case presents superficial peroneal nerve injury with dorsal foot pain lasting for more than 2 months after lateral ankle sprain and review the literature.

Acute cervical myelopathy is usually caused by fracture or fracture-dislocation of vertebra due to high energy trauma, not ruptured disc material. However, in this report, we present an unusual case that lead to severe neurological symptom such as motor weakness of upper and lower extremity during leisure sports activity in adjacent segment of previous anterior cervical fusion.

The stress fracture is a disease which results from the repeated application of an abnormal stress to the normal bone, typically occurs in metatarsal bone, tibia, fibular and femur, but medial malleolus is rare. We report a case of stress fracture of medial malleolus in 22-year old wrestler.

The glenohumeral bone deficiency plays an important role in the failure of arthroscopic shoulder stabilization procedures. Recently, several authors have described more novel approaches to treat the engaging Hill-Sachs lesion. Presented the 'Remplissage' technique that consists of an arthroscopic posterior capsulodesis and infraspinatus tenodesis to fill the Hill-Sachs lesion in addition to an arthroscopic Bankart repair. We report an arthroscopic technique in recurrent shoulder instability with large Hill-Sachs lesion with posterior capsulodesis and infraspinatus tenodesis.

The purpose of this study was to investigate effects of combined treatment with high intensity exercise and (-) epigallocatechin-3 gallate (EGCG), a potent free radical scavenger on a transcriptional level of hemoxygenase-1 gene in the large intestine. Sprague-Dawley rats were randomly divided into control group (CON, n=7), high intensity exercise group (HIE, n=7), EGCG group (EGCG, n=7), and EGCG plus high intensity exercise group (HIE + EGCG, n=7). Animals were given an intraperitoneal injection of EGCG with 50 mg of dosage per kg for four weeks 30 minutes before exercise. In order to induce HIE animals were allowed to ran on a treadmill with 0 degree of slope at speed of 28 m/min for 30 minutes. The exercise was performed four times a week for four week. The results of this study were as following; The expression level of hemoxygenase-1 mRNA of the high intensity exercise group was 15.21 times higher than that of the control group. The EGCG plus high intensity exercise group showed 5.98 times increased expression level of hemoxygenase-1 mRNA than control group. These results suggest that treatment of EGCG decrease the expression level of HO-1 mRNA through the removal of oxygen radicals produced by a high intensity exercise.

The purpose of this study was to analyze the muscle activities and gait pattern in lower limb depending on the orthotic type. Using electromyography (EMG), we evaluated muscle activities in 12 healthy men volunteered for this experiment. Surface electrodes were used to record the level of muscle activities in the tibialis anterior (TA), gastrocnemius (GCM), rectus femoris (RF), vastus lateral (VF), biceps femoris (BF) muscles during the gait. These signals were compared with % reference voluntary contraction (%RVC) which was normalized by integrated EMG (IEMG). The Gait cycle were divided into seven phases: loading response (LR), mid stance, terminal stance, pre swing (PS), initial swing (IS), mid swing, terminal swing. The results can be summarized as follows; there were increase of TA and GCM muscle during loading response phase & mid stance phase. There were increase of TA and BF muscle during terminal stance phase, pre swing phase, initial swing phase, mid swing phase and terminal swing phase.

Decline in muscle mass and muscle strength characterizes normal aging. As clinical studies show a relationship between high C-reactive protein (CRP) level and low muscle mass. The aim of this study was to investigate whether CRP level of inflammatory markers is associated with muscle strength in older persons by cross-sectional analysis with a sample 170 elderly men. We measured CRP levels, included isokinetic knee extensor strength and isometric back extensor strength among the subjects. Lower extremity strength (Isokinetic test) and lumber extensor muscle strength (Isometric test). From the result of this study, higher CRP level was generally associated with lower muscle strength and was significantly correlated with knee extensor strength and knee flexor strength (r=-0.353, r=-0.342, respectively). It was moderately correlated with lumbar extensor muscle strength (r=-0.233, p=0.05). After adjustment for covariates, higher CRP level was associated with knee strength and back extensor strength. Higher CRP level were generally associated with muscle strength in older men. Higher CRP level may contribute to the loss of muscle mass and strength that accompanies aging.

The purpose of this study was to investigate the physiological effects of forward and backward walking training on lower extremity muscle strength before and after exhausting exercise. Fourteen healthy male adults were randomly divided into backward walking (BW, n=7) and forward walking (FW, n=7) training groups. Each group took part in pre-test consisted of knee extensor and flexor isokinetic peak torque (PT), total work (TW), electromyography (EMG) before and after exhausting exercise. Exhausting exercise was used to measure lower extremity endurance, which is incremental treadmill running using the Bruce protocol. The BW and FW training groups participated in a 6 weeks training program, consisted of 3 sessions per week for a total of 18 sessions. After finishing the training program, the post-test was performed using the same method. BW training group showed significant increases in knee extensor/flexor PT (4.6%/13.9%), TW (17.34%), EMG (35.9%) before exhausting exercise and PT (23.9%/18.8%), TW (46.7%), EMG (59.8%) after exhausting exercise. But FW training group did not show a significant increase in knee extensor/flexor PT (0.1%/3.2%), TW (1.8%), EMG (10.9%) before exhausting exercise and PT (2%/1%), TW (5.6%), EMG (17.2%) after exhausting exercise. BW training has positive effects on lower extremity muscle strength, especially muscle endurance that is important to prevent muscle weakness during competitive sports.
