Background: Patients with stroke have limited ankle range of motion (ROM) due to soft tissue abnormalities around the ankle and thus experience functional impairment. Increased muscle tension and reduced ankle ROM impair gait and hinder the activities of daily living. Joint mobilization and stretching are effective interventions that improve gait performance by enhancing the ankle ROM. Objectives: To investigate the effects of ankle joint mobilization and calf muscle stretching on gait speed and gait performance in patients with stroke. Design: This was a randomized controlled trial. Methods: Twenty patients with stroke patients were randomized into two groups. The joint mobilization group (JMG) underwent anteroposterior mobilization of the talocrural joint and the joint mobilization stretching group (JMSG) underwent calf muscle stretching in addition to joint mobilization. Gait speed and gait parameters were measured using the 10-meter walk test and the GAITRite. Results: Both the JMG and JMSG groups showed significant improvements in gait speed, affected-side step length, and cadence after the intervention (P<.05). Conclusion: Joint mobilization and stretching were effective interventions for improving gait performance by enhancing ankle function in patients with stroke.

The modern convenient life formed by industrial development becomes lack of exercise and takes an interest in diet. Specially, professional walking shoes is developed as people take an interest in jogging, Those shoes, professional walking shoes or Dietshoes, increase exercise effects by change of heel types. Therefore, this study investigated motility effects by EMG experiment in order to measure Muscle Activities (MA) while wearing diet shoes (backless). Experiment was conducted by EMG measurement, from calf (gastrocnemius muscle), thigh (vastus muscle) and waist (erector spinae muscle), of 12 high school students. Exercise effects between the two shoes were analyzed by EMG (MF; Median Frequency, MPF; Mean Power Frequency, ZCR; Zero Crossing Rate). Results showed that the Dietshoes(MF: 48.21Hz, MPF: 65.0Hz, ZCR: 100.6Hz) had larger EMG value than that of Normal shoes(MF: 40.47Hz, MPF: 58.04Hz, ZCR: 82.09Hz). Also, in MA, the highest activities are showed in the calf, the second one is in waist, and last one is in thigh during gate. ANOVA between shoes in measurement parts showed significant effects in MF (gastrocnemius: p-value=.022, vastus laterals: p-value=.037, erector spinae: p-value=.082), MPF (gastrocnemius: p-value=.032, vastus laterals: p-value=.046, erector spinae: p-value=.090), and ZCR (gastrocnemius: p-value=.000, vastus laterals: p-value=.004, erector spinae: p-value=.134). And MA of Dietshoes is higher than that of Normal shoes, and decreasing rate of MA in Dietshoes is less than that of Normal shoes. Thus, this study validates exercise effects of Dietshoes.

The activity of lactate dehydrogenase in plasma and various tissues(skeletal muscle, cardiac muscle, liver, lung, kidney and spleen) of Korean native cattle in a Chonju abattoir, the Breeding Stock Farm and Animal Farm of Chonbuk University was determined by using ultra violet method. Using polyacrylamide gel electrophoresis, the lactate dehydrogenase isoenzyme distrimution of plasma and various tissues in Korean native cattle was studied. The plasma lactate dehydrogenase activity of Korean native cattle was $554.80{\pm}92.70IU/l$ and the lactate dehydrogenase activity of male plasma was $543.96{\pm}97.89IU/l$, which was lower than that of female plasma, $579.19{\pm}78.09IU/l$. The plasma lactate dehydrogenase activity of calf was $557.31{\pm}110.27IU/l$ and was no significantly different from that of adult Korean native cattle. But the range of calf lactate dehydrogenase activity was larger than that of adult Korean native cattle. In tissues, the lactate dehydrogenase activity was decreased in order of lung, kidney, spleen, liver, heart and skeletal muscle. The lung had the greatest activity and the skeletal muscle had the least. Lactate dehydrogenase isoenzymes in plasma and tissues were found to have a characteristic distribution and quantitative isoenzyme patterns. In plasma, the LDH1 usually had the greatest activity and other isoenzymes showed a decreasing tendency in order of LDH2, LDH3, LDH4 and LDH5. The distribution of lactate dehydrogenase isoenzymes had a wide variation in tissues. But the distribution of LDH isoenzymes in plasma was similar to that in kidney, and also cardiac muscle and spleen had similar pattern in LDH isoenzymes distribution.

Background : Although plank exercises is reported to the changes in muscle activity of the deep muscles and superficial muscles among the core muscles. However, no study has examined the effects of forearm plank exercise on tone and stiffness in the superficial back line muscle. Objective: To compare the effects of sling forearm plank exercises and mat forearm plank exercises on the superficial back line muscle tone and stiffness. Design: Randomized controlled clinical trial (single blind) Methods: The subjects were randomized to sling forearm plank exercise group (N = 8) or mat forearm plank exercise group (N = 8). The measurements were taken for each research group following exercises: the muscle tone and stiffness of upper lumbar muscles, lower lumbar muscles, long head of biceps femoris, and medial part of gastrocnemius among the superficial back line muscles. Results: Sling forearm plank exercise group Indicated statistically significant increases in stiffness of medial part of gastrocnemius (p<.05). However, mat forearm plank exercise group reported no statistically significant in muscle tone and stiffness of all measured muscles. No significant differences in measured variables were found between the groups. Conclusions: These results suggest that the forearm plank exercise performed with an unstable surface in the defined sling can increase the stiffness of calf muscle, but it is unlikely to achieve increases in muscle tone and stiffness of the overall superficial back line muscles.

PURPOSE: The aim of this study was to compare the effects of different loading swimming exercises on muscle recovery after sciatic nerve crush injury in rats. METHODS: For this study, thirty-one Sprague-Dawley male rats were randomly divided into five groups. There were the negative control group (NCG, n=5), the positive control group (PCG, n=7), the low intensity swimming exercise group (LISEG, n=7), the moderate intensity swimming exercise group (MISEG, n=7) and the high intensity swimming exercise group (HISEG, n=5). Each rat was weighed to determine the lead weight to be attached to the base of its tail. Subsequently, the PCG, the LISEG, the MISEG and the HISEG were underwent standard unilateral sciatic nerve crush. The LISEG (no load), the MISEG (lead weight equivalent to 2% average body mass) and the HISEG (lead weight equivalent to 4% average body mass) were received the 10 minute swimming exercise in a day for 10 days. The NCG and PCG were not received with any therapeutic intervention. The diameter of the calf muscle and the level of serum lactate dehydrogenase (LDH) were measured to detect the effects of the swimming exercise. RESULT: The maximum diameter of the calf muscles was significantly increased after seventh swimming exercise in the LISEG, the MISEG and the HISEG compared with the PCG (p<0.05). However, there was no statistically significant difference between the LISEG, the MISEG and the HISEG. Also, the level of the serum LDH was significantly decreased in the LISEG, the MISEG and the HISEG compared with the PCG (p<0.05). CONCLUSION: Taken together, these results suggest that swimming exercise could accelerate muscle recovery processes after crush injury, but the different intensity of the swimming exercise does not affect healing processes.

Purpose: Glomus tumors are uncommon benign neoplasms arising from the neuromyoarterial apparatus, usually seen in the nail bed of fingers. Most of this mass presents typical symptoms such as severe pain, point tenderness and hypersensitivity to cold like neuroma, gout or causalgia. Concerning about the origin, there were few written reports about extra-digit glomus tumor, especially that occurred in the skeletal muscule. Methods: A 48-year-old female complained of painful tender mass in her right calf aggravated several months ago. Her MRI and femoral angiogram showed a well defined hypervascular tumor such as hemagioma or hemagioendothelioma in the right calf. Surgical treatment was performed, and it proved glomus tumor in soleus muscle histologically. Results: After the operation, patient didn't complain of her symptoms any more and there was no evidence of recurrence during 1 year follow-up period. Conclusion: Authors have found only eight cases of intramuscular glomus tumor reported in the literature and present here the ninth case of an intramuscular glomus tumor and first case of soleus muscle.

PURPOSE: There are several standard interventions for managing Achilles tendinitis, including eccentric exercise and calf muscle stretches, orthoses, electrotherapy, and taping. However, no study has determined the effect of non-elastic taping on deloading the Achilles tendon while vertical jumping. Therefore, this study determined the effect of non-elastic taping on ankle dorsiflexion and the triceps surae muscle activity while vertical jumping in healthy subjects. METHODS: The study recruited 17 participants. A motion analysis system was used to measure the angle of ankle dorsiflexion and wireless surface electromyography was used to measure the soleus and gastrocnemius activities while vertical jumping. Non-elastic taping was applied on randomized leg side. All subjects performed maximal effort vertical jumps without and with non-elastic taping, with three trials for each condition. The mean peak dorsiflexion and muscle activities during the three trials were calculated and paired t-tests were used to compare the mean values without and with non-elastic taping. Significance was defined as (p<.05). RESULTS: The maximum angle of ankle dorsiflexion and activity of the gastrocnemius muscle decreased significantly when non-elastic tape was applied (p<.05), while there was no significant difference in the soleus activity between no-taping and taping (p>.05). CONCLUSION: We introduce non-elastic taping as a method to decrease maximum ankle dorsiflexion and gastrocnemius activity while vertical jumping.

Purpose : This study was conducted to investigate and analyze the physical health of older Koreans with sarcopenia and locomotive syndrome and identify the related factors. Methods : In this study, the sarcopenia and locomotive syndrome evaluations were applied to 210 elderly people, and the sarcopenia group was 36, the locomotive syndrome group was 164, and the normal group was 10. After group selection, a physical health status survey was conducted. The physical health status was assessed via body composition analysis, physical characteristics survey including measurement of waist and calf circumference, investigation of diseases currently being diagnosed by a doctor, and frailty measurements. The collected data were statistically analyzed using one-way ANOVA, the Kruskal-Wallis test, and the Chi-square test. Results : There were significant differences between groups in all elements of physical characteristics including body mass index, waist circumference, and calf circumference. Among them, a consistent result was found that the normal group had the largest amount of muscle mass and the sarcopenia group had the least amount of muscle mass in the factors related to muscle mass. However, the factors relating to fat mass and obesity also showed significant differences between the groups, but the results were not consistent. Considering the group differences in current diseases, a significant difference was only detected for osteoporosis among 12 diseases. Moreover, those in the sarcopenia group had the highest rate of osteoporosis. And there was no significant difference between the groups in the total score of the frailty measurement, but there was a significant difference between the groups in the frailty measurement levels. Conclusion : This study on physical health status confirmed that muscle mass-related factors, osteoporosis, and frailty levels were significantly related to sarcopenia and locomotive syndrome.

Purpose: The study was undertaken to investigate the electromyographic activities of the gluteus maximus (GM), hamstring (HAM), and multifidus (MF) in three different sling locations during bridge exercise in the supine position. Methods: Twenty healthy male subjects participated. An electromyography device was used to measure the muscle activities of the GM, HAM, and MF muscles. Subjects were asked to perform bridge exercises with three different sling locations as follows: 1) Bridge exercise with an ankle sling; BEAS, 2) Bridge exercise with a calf sling; BECS, and 3) Bridge exercise with a knee sling; BEKS in random order. The analysis was conducted using one-way repeated ANOVA and the Bonferroni post hoc. Significance was set at α=0.01. Results: HAM muscle activity was significantly different in the three conditions (BEAS, BECS, BEKS) (adjusted p-value [p_adj]<0.01), and HAM muscle activity was significantly smaller during BEKS than during BEAS or BECS (p_adj<0.01). Muscle activity ratio (GM/HAM) during BEKS was significantly greater than muscle activity ratios during BEAS or BECS (p_adj<0.01). Conclusion: BEKS is recommended to inhibit HAM muscle activity and improve the GM/HAM muscle activity ratio.
