This study was conducted to investigate the effect of the active exercise program using sling on the pain and balance of total knee replacement patients. Subjects were 20 patients who received total knee replacement and are hospitalized, 10 patients in each group were randomly assigned to a group (CPM group) that applied only CPM (Continuous passive motion) and a group (CSG) that combined CPM with a active exercise program using sling. CG was performed CPM 5 days a week, CSG performed CPM 2 days a week and a active exercise program using sling 3 days a week, and each intervention was performed for 40 minutes a day for a total of 4 weeks. Pain was evaluated using VAS (Visual analog scale), and balance was measured using BT4 (Balance training 4) to measure C90 area, trace length, and Sway average velocity with eyes open and closed. As a result, there was a significant decrease in pain in both groups, and there was also a significant difference in the amount of change between groups. In balance, all variables except C90 of CG showed significant changes after intervention, and there was a significant difference between C90 and Vel with eyes closed in the amount of change between groups. Therefore, we believe that CPM and active exercise program using sling are effective interventions to reduce pain and improve balance in total knee replacement patients.

Background: This study aims to examine the effects of sling exercise and common exercise on the pain level of various body parts. Methods: This study divided the subjects into a sling-exercise group and a common exercise group to for each group across the measurement times after practicing exercises twice per week for 8 weeks (total 16times). To compare the means of the experimental group and the control group on each variable, the ANOVA for repeated measure was used and if there was any significant difference across the measurement times, post-hoc comparisons were conducted for the difference. The T-tests for group difference according to exercise type on each of the variables showed the results as follows. Results: The results of this study suggest that there were significant difference in pain in shoulder pain, but no significant difference could be found in the Thoracic pain & Knee joint pain. There was no significant difference to distinguish between the sling exercise and the common exercise. Conclusions: Currently the sling exercise is not spread out widely in Korea, so that the recognition and studies of the sling exercise is still lacking. Hence, this study can hopefully facilitate popularity of the sling exercise and systematic prospect studies on it in the near future.

Chronic progressive external ophthalmoplegia (CPEO) is a complex slowly progressive mitochondrial disorder characterized by extraocular muscle weakness with or without multisystem involvement. The mainstay of therapy in a patient with CPEO is supportive. However, in moderate cases, surgery might be indicated including surgeries for ptosis and strabismus. In this article, we report a Saudi patient with CPEO due to compound heterozygous variants in the DNA polymerase gamma (POLG) gene c.2246T>C p.(Phe749Ser) and c.1735C>T p.(Arg579Trp), which are classified as pathogenic. Proper diagnosis with genetic testing confirmation is important to guide the management and counsel the patient about the prognosis and the management options. The patient was successfully managed with bilateral frontalis sling and illustrates the importance of surgical intervention to improve vision and cosmetic appearance in patients with CPEO. We emphasize the importance of multidisciplinary care in the management of cases of mitochondriopathy, especially CPEO.

This study examines the effects of different types of bridge exercises on the thickness of trunk muscles through ultrasound fusion imaging on 32 students. The thickness of the internal oblique (IO), external oblique (EO), transverse abdominis (TrA), and multifidus (Mf) muscles were measured in three different bridge exercises. The exercises included a supine bridge exercise, which was performed on a fixed support surface (Exercise A), a gym ball bridge exercise (Exercise B), and a sling bridge exercise (Exercise C). There were significant differences among the three bridge exercises in the IO, TrA, and Mf muscles. The IO was thickest in Exercise B followed by Exercise A and C. In contrast, the TrA and the Mf muscles were thickest in Exercise C followed by Exercise A and B. Therefore, the sling bridge exercise may be a more effective method of enhancing trunk muscle thickness than the exercises performed in other positions. Until recently, no previous studies had observed substantial changes in muscle thickness using ultrasound fusion imaging. This study suggests that sling bridge exercises contribute most to the activation of trunk muscles. Therefore, the research can contribute to the prescription and application of bridge exercises in clinical practices.

PURPOSE: The purpose of this study was to investigate the change of triceps surae activation during heel raise test in standing among knee flexion angles($0^{\circ}C$, $30^{\circ}C$, $45^{\circ}C$, $60^{\circ}C$). METHODS: Twenty healthy individuals performed unilateral plantarflexion in standing with $0^{\circ}C$, $30^{\circ}C$, $45^{\circ}C$, $60^{\circ}C$ knee flexion. Activity of medial gastrocnemius(MG), lateral gastrocnemius(LG), soleus(Sol) was recorded with surface electromyography(EMG). RESULT: The muscle activations induced the four different positions were compared and results showed that was significant difference MG and LG while the angle increase from $0^{\circ}C$ to $30^{\circ}C$, $45^{\circ}C$, $60^{\circ}C$ but Sol did not show significant differences in every angle. CONCLUSION: This study suggest that $30^{\circ}C$ knee flexion is required to induce a significant mechanical disadvantage of gastrocnemius.

There is a method for stringing conductors which is connected to a wire over transmission towers by helicopter or human power and the wire and conductors are pulled by an engine puller. The length of one string section is usually 4-6 km and 2-4 conductors are strung at the same time with a single wire. A tensioner is used to maintain the sag and a running board is installed between the wire and conductors to prevent the rotation of conductors but the variance in topology, the line angle and unequal wiring tension between conductors causes conductor rotation damage or the conductor connection point to breakaway when the pulley is passed. This paper presents a method to prevent conductor rotation during stringing by inserting a pulley in the running board and equally maintaining conductor tension by sling wire after developing and testing.
