Purpose: The purpose of this study was to investigate the effects of extracorporeal shock-wave therapy (ESWT) on pain, grip strength, and upper-extremity function in patients diagnosed with lateral epicondylitis and to provide an effective intervention method for lateral epicondylitis. Methods: Twenty patients with lateral epicondylitis were randomly assigned to the ESWT group (n = 10) and the stretching exercise group (n = 10). Interventions in both groups were performed six times twice a week for three weeks. The visible analog scale (VAS) was used to measure pain change. A dynamometer was used to measure grip strength (GS). Patient-rated tennis elbow evaluation (PRTEE) was used to measure the upper-extremity function. Results: There were significant differences in pain, grip strength, and upper-extremity function in both groups before and after intervention (p < 0.05). There were also significant differences in pain, grip strength, and upper-extremity function between the groups after intervention (p < 0.05). Conclusion: This study showed very positive improvement in pain, grip strength, and upper-extremity function after ESWT in patients with lateral epicondylitis. Therefore, ESWT can be recommended for patients with lateral epicondylitis.
The purpose of this study was to investigate a relationship among Taekwondo, soccer and gymnastic athletes their balance ability and lower extremity muscle strength, muscle endurance and also whether these variables show differences by sports type. For this purpose, 10 Taekwondo athletes, 10 soccer athletes and 10 gymnastic athletes that is a high school in I area were selected and their balance ability, isokinetic muscle strength and muscle endurance were measured by using force platform (AMTI) and isokinetic measurement (HUMAC NORM). Then the following results were obtained by conducting pearson product-moment correlation analysis and one-way ANOVA. In case of both right and left foot one-leg standing with open-eyes, there was a relation between both knee extension maximal muscle strength of Taekwondo, soccer, gymnastic athletes and balance ability, and in case of right foot one-leg standing with open-eyes, there was a relation between that is right plantar flexion and dorsi flexion maximum muscle strength and muscle endurance of Taekwondo, soccer, gymnastic athletes and their balance ability. Furthermore, in case of left dorsi flexion maximum muscle strength, there were significant differences in order of Taekwondo, gymnastics and soccer, and for isokinetic plantar flexion maximum muscle endurance, both right and left showed significant differences in order of Taekwondo, gymnastic and soccer.

Purpose : The purpose of this study was to evaluate the effect of 6 weeks of sling exercises on female patients 20 years of age with low back pain according to flexibility, balance, muscle strength and pelvic tilt. Method : The 20 female patients who complained of back pain were divided into two groups. The experimental group exercised for 40 minutes, 3 times a week for 6 weeks. The control group did not. Both groups were measure for flexibility, balance, muscular strength, and pelvic tilt angle. Result : Curvature of the experimental flexibility, stretch, balance, muscle strength of the trunk forward, backward, left rotation, right rotation for the sling exercise group had significant differences. However, pelvic tilt did not show a significant difference. Control of the stretch of the flexibility, balance, and muscle strength of the trunk posterior showed significant differences for the sling exercise group. Conclusion : Although significant differences were found in flexibility, balance, muscular strength, there was no difference in pelvic tilt. When selecting subjects, we believe patients with regular patterns of pain will be more effective for statistical analysis of the changes in pelvic tilt.

Objective : The purpose of this study was to verify the differences of expressed character strengths graded as per the Korean Strength Scale, based on the type of work. Methods : A total of 2,444 conglomerate workers were classified into two groups: 1,356 office workers and 1,088 production workers. The subjects were examined through a web or mobile application based on the Korean Strength Scale. The Korean Strength Scale consists of a total of four top entries and 25 sub-items with appropriate validity. Results : The difference in the average score of sum of character strengths between the two groups was not significant. In the office worker group, character strengths such as love of learning, creativity, perspective, curiosity, facilitation, judgment and faith had significantly high scores. On the other hands, modesty, hope, gratitude, sincerity, magnanimity and self-regulation were high in the production worker group. The results remained unchanged in additional analysis of covariants as sex, age and education level, except for self-regulation and faith. Conclusion : Our results suggest significant differences in the character strengths between the two types of work; however, the average of sum of character strength score remains unchanged. These results may help to understand differences between work environments and thus help to establish a positive foundation.

Purpose : Several studies have investigated the effects of dynamic stretching (DS) and self-mobilization (SM), however, studies comparing the two interventions are rare. Therefore, the purpose of this study was to compare the effects of DS and SM on ankle strength, dorsiflexion range of motion (DFROM), and balance to determine which is superior. Methods : Thirty-two healthy young adults participated in this study. Participants were randomly assigned to two groups (SM and DS). DS was performed for the purpose of stretching the medial gastrocnemius muscle. For the SM group, ankle joint SM was performed in three ways. For all participants, the following measurements were performed as pre- and post-tests: isometric strength of dorsiflexor and plantar flexor, weight-bearing lunge test (WBLT) to evaluate DFROM, Tetrax system to evaluate static balance, and y balance test (YBT) to evaluate dynamic balance. Differences before and after the intervention within each group were compared using paired t-test. Also, the variable's variation was compared between groups using an independent t-test. Results : Significant differences were found in ankle dorsiflexor strength, WBLT, YBT, weight distribution index (WDI) (pillow and opened eyes; PO), and stability index (ST) (normal and closed eyes; NC) before and after intervention in the SM group (p<.05). In the DS group, significant differences were found in ankle dorsiflexor and plantar flexor strength, WBLT, YBT anterior, WDI (normal and opened eyes; NO, PO), and ST (NO, NC, PO, pillow and closed eyes) before and after the intervention (p<.05). Ankle plantar flexor strength and WDI (PO) were significantly different between groups. Conclusion : Based on the results of this study, DS or SM can be considered as a possibility for selective use according to variables for improving ankle joint function (DFROM, muscle strength, balance).
To examine the blood lipids, muscle strength and flexibility at low back, and muscle strength in the knee joint, 44 women, who were diagnosed as chronic low back pain patients and aged between 40 to 50 years old, were recruited as the subjects.

One of the methods to improve the softness and comfortness of denture base is the use of soft denture liners. In this study, specimens were made by 2 kinds of acrylic based soft lining materials and 2 kinds of silicone based soft lining materials, and bonded to acrylic resin(Lucitone $199^{(R)}$). Then they were tested the differences of tensile bond strengths according to the materials, thickness, surface treatment and failure mode. 1. Tensile bond strength according to soft lining materials was increased in order of Coe-$soft^{(R)}$, $Mollosil^{(R)}$, $Trusoft^{(R)}$, Ufi-Gel $C^{(R)}$. The differences between groups were statistically significant at level of 0.05. 2. Tensile bond strength according to thickness of soft lining materials was increased in order of 3mm, 2mm, 1mm. The differences between groups were not statistically significant. 3. Tensile bond strength of treated surface showed higher bond strength than nontreated surface. The difference between groups was not statistically significant. 4. The failure mode of Coe-$soft^{(R)}$, $Trusoft^{(R)}$, $Mollosil^{(R)}$ were mainly cohesive failure, and that of Ufi-Gel $C^{(R)}$ were mainly adhesive failure.
Background: Prolonged standing during work causes a lower extremity pain and disorders. Patellofemoral pain syndrome (PFPS) is one of the common diagnoses of the knee pain. Although the etiology of PFPS is not completely understood, it is considered to be multifactorial. Objects: The purpose of this study was to investigate difference in strength of knee muscles, quadriceps:hamstring muscles strength ratio (Q:H ratio), asymmetry ratio of knee muscles strength and dorsiflexion range of motion (ROM) between standing workers with and without PFPS. Methods: Twenty-eight standing workers with PFPS and 26 age-, height-, and weight-matched standing workers without PFPS participated in this study. A tension sensor measured knee muscle strength, and motion sensor measured dorsiflexion ROM. The asymmetry ratio of knee muscles was calculated by a specific formula using the knee muscles strength of the dominant side and the sound side. An independent t-test was used to identify significant differences in the strength, ROM, Q:H ratio, and asymmetry ratio between the PFPS and normal groups. Results: The standing worker with PFPS have significantly lower dorsiflexion ROM (p < 0.000) and higher asymmetry ratio of the hamstring muscles strength (p < 0.000) compare to the standing worker without PFPS. No significant differences were seen in the strength of quadriceps muscle and hamstring muscles, Q:H ratio, and asymmetry ratio of quadriceps muscle strength. Conclusion: There was a significant difference in the asymmetry ratio of the isometric hamstring muscle strength. This finding suggests that the asymmetry ratio of isometric hamstring muscle strength may be more important than measuring only the hamstring muscle strength of the PFPS side. Furthermore, the results of this study showed a significant difference in dorsiflexion ROM between the standing industrial workers with and without PFPS. Dorsiflexion ROM and isometric hamstring muscle strength should be considered when evaluating the subjects with PFPS.
Background: Hip flexor muscles are very important in the hip joint structure as a mover and stabilizer. In addition, isometric hip flexor strength in the supine position needs to be considered with isometric core strength (WICS) to measure a precise strength in a clinical way. Objects: We compared isometric hip flexor strength in the supine position in subjects with and without WICS (between factors) and conditions with and without an external support (within factors). Methods: A total of 34 subjects (16 with WICS, 18 without WICS) participated in this study. We used the double-bent leg-lowering test to divide the subjects in two groups according to the presence of WICS. Isometric hip flexor strength was evaluated in the supine position both with and without an external support condition. The two-way mixed analysis of variance was applied to identify significant differences between groups (with vs. without WICS: between factors) and conditions (with vs. without an external support: within factors). Statistical significance was set at α = 0.05. Results: In subjects with WICS, isometric hip flexor strength was greater with an external support than without it (p = 0.0064). In subjects without WICS, there were no significant differences in isometric hip flexor strength in the presence or absence of an external support (p = 0.075). The isometric hip flexor strength was significantly greater with an external support condition in particular in subjects with WICS. Conclusion: The findings of this study reported that an external support condition in individuals with WICS may contribute to the improvement of isometric hip flexion strength in the supine position. Therefore, isometric core strength should be evaluated to distinguish the weakness between core region and hip flexors.

The purpose of this study was to implement a program of combined muscle stregth and proprioceptive exercises and to examine the impacts of these exercises on functional ankle instability(FAI). Experiments were conducted with 30 adult males and females in their 20s, and the exercise programs were implemented three days per week for four weeks. FAI was defined as a feeling of giving way after an ankle sprain and having a Cumberland ankle instability tool score of 24 points or less. The study subjects were randomly assigned to either a control group, a muscle-strengthening exercise group, or a combined muscle-strengthening and proprioceptive exercise group consisting of 10 subjects each. A Biodex isokinetic dynamometer was used to assess the subjects'ankle strength at selected speeds of $60^{\circ}/sec$ and $120^{\circ}/sec$. The peak torque % body weight showed significant differences in plantar flexion, dorsiflexion, inversion, and eversion. There were also significant differences in proprioception. The results suggest that applying combined muscle-strength and proprioceptive exercises to subjects with FAI is a more effective intervention than applying only muscle-strengthening exercises.
