Walking shoes for walking and jogging have been used to enjoy lots of leisure time. Functional shoes such as walking shoes have special functions to improve body motility by changing of shoe shapes. The walking shoes could improve the motility by structural transformation of outsole as increase degrees of heel and toe. The study on insoles has not been conducted enough on the contrary of the study of outsole. The purpose of this study is to perform ergonomics analysis whether the Arch Supported insoles have an improving effect of muscle activities or not. Experiments were performed with 6 subjects who are health and haven't experienced any diseases past. EMG(Electromyography) and Foot Pressures were measured repeatedly for 5 seconds at 0 hour, after 1 hour and after 2 hours of walking. Insoles used for experiment are normal insole, insole inserted Arch Support and pad. The electrodes for EMG measurement were set on waist (erector spinae), and thigh (vastus lateralis), calf (gastrocnemius). Evaluations of EMG were analyzed by shift of MF (Median Frequency) and MPF (Mean Power Frequency). Foot Pressure was analyzed by mean pressure of feet and change of walking time. As results, Arch Support insole had larger frequency shift value than that of normal insole. Frequency shift between Arch Support insoles and normal insole showed significant difference on 95% confidence interval. And insole 1 has the highest value of frequency shift. For results of foot pressure, Arch Support insoles show continuous decreasing tendency when comparing with normal insoles by changing of times. Also, insole 1 has the highest decreasing value of foot pressure. Therefore, this study presented that the Arch Support insole can promote muscle activities and improves comfort for a prolonged walking.
BACKGROUND/OBJECTIVES: Maintaining total muscle mass in the older adults with swallowing difficulty (dysphagia) is important for preserving swallowing function. Increasing protein intake can help sustain lean body mass in the older adults. The aim of this study was to evaluate the effect of various high-protein texture-modified foods (HPTMFs) on muscle mass and perform dietary assessment in ≥ 65-yrs-old patients with dysphagia. SUBJECTS/METHODS: Participants (n = 10) received the newly developed HPTMFs (average 595.23 ± 66.75 kcal/day of energy, 54.22 ± 6.32 g/day of protein) for 10 days. Relative handgrip strength (RHS), mid-upper arm circumference (MUAC), body composition, mini nutritional assessment (MNA), mini dietary assessment (MDA), and Euro Quality-of-Life questionnaire 5-dimensional classification (EQ-5D) were assessed. RESULTS: After 10 days, an increase in MUAC (26.36 ± 2.35 cm to 28.50 ± 3.17 cm, P = 0.013) and RHS (0.38 ± 0.24 kg/kg body weight to 0.42 ± 0.22 kg/kg body weight, P = 0.046) was observed. Although MNA, MDA, EQ-5D, subjective health status, muscle mass, and calf circumference showed a tendency to increase after intervention, no significant differences were found. CONCLUSIONS: These results suggest that the HPTMFs can be used for improving the nutritional and health status in patients with dysphagia.
Purpose: The purpose of this study was to evaluate the clinical results of the old Achilles tendon rupture treated with modified flexor hallucis longus (FHL) tendon transfer. Materials and Methods: Seventeen patients with old Achilles tendon rupture treated with modified FHL tendon transfer between March 2004 and February 2008 were enrolled in this study. Technically FHL was pass through the distal portion of the ruptured tendon instead of the drilled hole made on the calcaneus. The mean age of the patients was 37 years (range, 22~67 years), mean follow-up period was 28 months (range, 12~30 months). Patients' subjective satisfaction, calf circumferential diameter, range of motion of ankle and AOFAS ankle-hind foot score and Arner-Lidholm score was evaluated. Results: The average gap between the ruptured tendon was 52 mm (range, 47~56 mm). The AOFAS score improved from 47 pre-operatively to 91 points at the last follow-up. Sixteen patients were satisfied with the result free from discomfort, a patient had mild discomfort who had DM. fourteen patients had decreased range of motion less than 5 degrees while 2 patients had more than 7 degrees decrease compared to the intact side but had no discomfort in daily activities. Nine patients had less than 1 cm calf circumferential diameter difference and 7 patients had 1 to 3 cm diameter difference compared to the intact side. One who had more than 3 cm diameter difference had deteriorated muscle strength. Conclusion: Modified FHL tendon transfer can be a useful technique for the treatment of old Achilles tendon rupture when the gap is with large gap placed too proximal.

Objectives: Exercise with partially restricted blood flow is a low-load, low-intensity resistance training regimen which may have the potential to increase muscle strength in the obese, elderly and frail who are unable to do high-load training. Restricted blood flow exercise has also been shown to affect blood vessel function variably and can, therefore, contribute to blood vessel dysfunction. This pilot study tests the hypothesis that unilateral resistance training of the leg extensors with partially restricted blood flow increases muscle strength and decreases vascular autoregulation. Methods: The subjects were nine normotensive, overweight, young adult African-Americans with low cardiorespiratory fitness who underwent unilateral training of the quadriceps' femoris muscles with partially restricted blood flow at 30% of the 1-repetition maximum (1-RM) load for 3 weeks. The 1-RM load and post-occlusion blood flow to the lower leg (calf) were measured during reactive hyperemia. Results: The 1-RM load increased in the trained legs from $77{\pm}3$ to $84{\pm}4 kg$ (P < 0.05) in the absence of a significant effect on the 1-RM load in the contralateral untrained legs (P > 0.1). Post-occlusion blood flow decreased significantly in the trained legs from $19{\pm}2$ to $13{\pm}2mL{\cdot}min^{-1}{\cdot}dL^{-1}$ (P < 0.05) and marginally in the contralateral untrained legs from $18{\pm}2$ to $16{\pm}1mL{\cdot}min^{-1}{\cdot}dL^{-1}$ (P = 0.09). Changes in post-occlusion blood flow to the skin overlying the trained and the contralateral untrained muscles were not significant. Conclusion: These results demonstrate that restricted blood flow exercise, which results in significant gains in muscle strength, may produce decrements in endothelial dysfunction and vascular autoregulation. Future studies should determine whether pharmacopuncture plays a role in treatments for such blood vessel dysfunction.
An 18-year-old boy was admitted with chest discomfort, nausea, and dyspnea at rest. At the age of 3 years, he underwent muscle biopsy and dystrophin gene analysis owing to an enlarged calf muscle and elevated serum kinase level (6,378 U/L) without overt weakness; based on the results, Becker muscular dystrophy (BMD) was diagnosed. The dystrophin gene showed deletion of exons 45 to 49. He remained ambulant and could step upstairs without significant difficulties. A chest roentgenogram showed cardiomegaly (cardiothoracic ratio, 54%), and his electrocardiogram (ECG) showed abnormal ST-T wave, biatrial enlargement, and left ventricular hypertrophy. The 2-dimensional and M-mode ECGs showed a severely dilated left ventricular cavity with diffuse hypokinesis. The systolic indices were reduced, including fractional shortening (9%) and ejection fraction (19%). Despite receiving intensive medical treatment, he died from congestive heart failure 5 months after the initial cardiac symptoms. We report a case of BMD with early-onset dilated cardiomyopathy associated with deletion of exons 45 to 49. Early cardiomyopathy can occur in BMD patients with certain genotypes; therefore, careful follow-up is required even in patients with mild phenotypes of BMD.

The entrapment of the popliteal artery is a rare cause of ischemia of the lower extremities among young males. The development of local occlusive or aneurysmal changes of the popliteal artery is caused by abnormal anatomic relationships between vascular and musculo-tendinous structures in the popliteal fossa. An 18-year-old male visited our outpatient clinic with the chief complaint of claudication in his right calf. Three dimensional CT angiography showed an occlusion of the popliteal artery and less opacified arteries of the right leg. Intraoperatively, the popliteal artery was compressed by an accessory muscle band arising from the medial head of the gastrocnemius. After release of the muscle band, thrombectomy with endarterectomy was done. Three years after surgery, he is doing well without any problems.

From November 1978 to April 1979, there occurred among cows many cases of abortion, premature birth, stillbirth and congenital arthrogryposis or hydranencephaly in Kyongki-do province in Korea. Epizootics recurred between February and May, 1980 in the same area. Six calves born at 8 or 10 months of gestation were examined by means of pathology and one of the calves was examined by serological test. And a survey on local occurrence of the disease in other than Kyongki-do province, was conducted. 1. At necropsy, some calves showed distinct lesions such deformities of the limbs and the vertebrae as arthrogryposis or scoliosis. Other calves revealed arthrogryposis and partial or total deficience of the cerebral hemispheres with hydranencephaly. 2. In the calves with deformities the skeletal muscle showed histologically severe hypoplasia of the muscle fibers with cellular infiltration. In the central nervous system of the calves with hydranencephaly there were minute cystic cavitation and the decrease of ventral horn cells of the spinal cord in the number. 3. Similar epizootics were also observed in the same season in the other several provinces such as Chungoheongnam-do, Kangwon-do and Jeonrabuk-do. 4. Anti-Akabane virus antibody was detected in precolostral blood from the calf with arthroglposis and hydranencephaly syndrome. 5. On these findings of the disease it was diagnosed as Akabane disease presenting the first report on the epizootics in Korea.

This study measured and analyzed pressure at each measurement part of imported compression stockings sold in Korea to provide basic information to establish a pressure standard and grade ranking. This study used 40 medical compression stockings imported from 6 countries. Pressure measurements were taken at 11 points: front side and back side of ankle, end-point of the gastrocnemius muscle, front, inner side, back, and outer side of calf, back side of below knew girth, inner side, and outer side of mid-thigh girth, and inner side of thigh girth. AMI 3037-10 and AMI 3037-2 were used for measurements taken inside an environmental chamber at a temperature of $21^{\circ}C$ and a relative humidity (RH) of 65%. For the measurements, 11 air pack sensors were attached to a wooden model leg (Hohenstein) and three measurements were taken at each measurement point in three minutes. The average of these measurements was used for analysis. The findings of this study were as follows. As for the front side of the ankle, of the 40 products, 14 products (6 USA, 2 Swiss, 3 Italian, and 2 Taiwanese) were within the pressure range indicated on the product label; however, no German products fell within the pressure range. A total of 8 products (5 USA, 1 Swiss, 1 Italian, and 1 German) were gradient compression type; however, no Japanese or Taiwanese product were of this type. The majority of products had the highest pressure at the end-point of the gastrocnemius muscle. Only 3 products, 1 USA (Jobst Opaque 30-40mmHg), 1 Swiss (Sigvaris Cotton 34-46mmHg) and 1 Italian (Jobstocking 25-32mmHg), had measurements that met the indicated standard pressure, were a gradient compression type, and met the overall standard for compression stockings.

Background : Hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome is a rare, autosomal recessive metabolic disorder which is caused by genetic mutations that disrupt the urea cycle. It is characterized by variable clinical presentation and the age of onset. Patients may present with gait disturbance and progressive paraplegia and muscle tightness in the lower extremities. The use of botulinum toxin in metabolic disease has rarely been discussed. We describe a case of a 14-year-old-boy with HHH syndrome, who presented with a several - month history of gait disturbance and lower extremity weakness. Case presentation : A 14-year old male had a history of recurrent upper respiratory tract infections, occasional vomiting, loss of appetite, and general weakness, all of which started since he was 10 months old. He was diagnosed with HHH syndrome at one year of age. At the age of 14, he was referred for the assessment and treatment of his gait disturbance and aggravated weakness of the lower extremities. Brain MRI, electrodiagnostic study and blood test were performed to exclude any lesions related to neurologic dysfunction. Botulinum toxin type A were injected into muscles of adductor longus, adductor magnus, lateral and medial hamstring, and lateral and medial gastrocnemius muscle heads under needle electromyography guidance to reduce lower limb spasticity. Intensive physical therapy including gait training and stretching exercise of adductor and calf muscles were also provided. After intensive physical therapy and botulinum toxin injection to reduce lower limb spasticity, he was able to ambulate for 20 meters independently without any walking aids. There were no adverse events after the injection. Conclusion : Botulinum toxin injection is a safe and effective therapy for patients with HHH syndrome who suffer from gait disturbance.
[Purpose] We aimed to identify the effects of marine oligomeric polyphenol (MOP) intake in elderly individuals with sarcopenia. [Methods] Older adults (aged 65 years or older) were recruited based on the diagnostic criterion for sarcopenia and were randomly assigned to the MOP intake group (n=10) or the placebo (PBO) intake group (n=10). To determine the effect of MOP intake received for four weeks, the pre- and post-intake body composition (weight, skeletal muscle mass, and bone density) and senior fitness tests were assessed. [Results] Our results showed there were significant differences in the skeletal muscle mass (p=0.039), bone density (p=0.020), fat-free mass index (p=0.026), and 2.4 m up and go test (p=0.001) between pretest and post-test. There was a significant difference between the pre-test and post-test and an interaction effect for the one-leg stand test (p=0.010 and p=0.049, respectively). However, there were no significant differences in body fat percentage, calf circumference, grip strength, or the chair rise test. [Conclusion] Some variables exhibited significant differences in the pre- and post-assessments, and there was an interaction effect for the one-leg stand. However, this was insufficient to prove the effectiveness of MOP intake in improving sarcopenia. Therefore, additional studies are essential to examine the effects of MOP intake and exercise intervention on the body composition and fitness of patients over a longer period.
