Purpose: The purpose of this study was to investigate the effects of active abduction exercise of the great toe on the medial and lateral sesamoid bones in hallux valgus (HV) patients by measuring radiography. Methods: In this study 27 young subjects were separated into two groups (normal group and HV group). Two pictures were taken by radiography while maintaining resting and while holding maximal active abduction of the great toe in sitting position on an x-ray table. All radiographs were used to measure the distance of the medial and lateral sesamoid bone from the longitudinal axis of the first metatarsal bone, respectively. Paired t-test was used for analysis of the resting and active abduction exercise in groups. Independent t-test was used to evaluate statistical significance between normal group and HV group. The statistical significance level was p<0.05. Results: In active abduction exercise of the normal group, distance of the medial and lateral sesamoid bones was not significantly different compared to resting condition. In active abduction exercise of the HV group, change of distance of the medial and lateral sesamoid bones showed statistically significant difference compared to resting condition. The distance between the medial sesamoid bone showed a more significant decrease in the HV vs. normal group, while the distance between the lateral sesamoid bone was significantly greater in the HV vs. normal group. Conclusion: These findings suggest that active abduction exercises, to reduce or prevent deterioration of the HV angle, should be considered for sesamoid bone displacement to improve muscle balance in the great toe.

Purpose: Electrical stimulation is one of several treatments recommended for RA patients. Electrical stimulation of RA patients, reduces pain, or facilitates joint motion prior to exercises. However, there is still limited evidence on the efficacy of electrical stimulation and thus any conclusions drawn about this method remain controversial. Recently, Microcurrent Electrical Neuromuscular Stimulation (MENS) has received significant attention as a potential method of electrical stimulation. In this study, we investigated the effect of microcurrent treatment in rheumatoid arthritis rat. Methods: Subjects were allocated either to the control group or experimental group, which was subject to microcurrent stimulation. Interleukin-1 expression in the metatarsophlangeal joint and the oedema index in the ankle were used for classification and subsequent evaluation of pathology. Subjects were assessed at 1, 7 and 14 days after inducing rheumatoid arthritis through adjuvant injection. Thirty-six subjects, 18 in each group, were used in this study. Statistical analysis was performed by calculating the differences between the two groups and between each interval assessment. Categorical variables were compared between the two groups with the paired-T test. The one-way ANOVA test was performed to assess changes in ordinal variables. Results: Baseline characteristics were similar in both groups. Statistically significant differences were found between the two groups. The biological marker of pro-inflammatory cytokine and oedema index were decreased in response to this treatment. Conclusion: These data show that treatment of rheumatoid arthritis with a microcurrent stimulation device reduced the oedema index and pro-inflammatory cytokine IL-1.

Purpose: The purpose of this study was to classify patients with chronic back pain according to the degree of their back pain, and to compare the pain dysfunction index with the qualitative changes in abdominal muscles. Therefore, we aimed to provide a basis for the treatment intervention method for patients with back pain. Methods: Twenty patients with chronic back pain were purposive sample to a group of 10 patients with a back pain index of 60 % or more and a group with less than 60 % of back pain, and the subjects who voluntarily participated in the study After receiving the letter, I conducted the research the dysfunction of back pain was measured by the Korean version of the Oswestry Disability Index (KODI), and the ultrasonic wave (Ultrasound MyLabOne, ESAOTE, Italy) And the white area index, and the abdominal muscle movement was used as the exercise instrument POWER breathe K5 (Hab direct, UK), which strengthens the respiratory muscles through threshold-muscle traction. Result: In this study, patients with chronic back pain were subjected to breathing exercises, which led to the decrease in back pain dysfunction. The ultrasonographic analysis of abdominal muscles revealed that both the white area index and muscle image density in the skeletal muscle and in the outer muscle of the abdomen gradually decreased over time. Conclusion: It is thought that introducing back pain patients to abdominal muscle reinforcement training is effective in improving the functions of the patients' muscles, thus increasing their quality of life.

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.

This article a little bit lack of elements for the basis of study of health care in the respect of taking a certain expert group as the sample. However researcher chose people who is in same situation with himself and tried to make clear how to do for their behavior of health care to know that how the experts groups are taking care of their health. For the study, the main aim of this article is studying the health care situation of experts group which is taking crucial role in the economy, society and cultural field. When it comes to the experts group's health care by eating habits and exercise related program is, first, it indicates that most people are eating for their health, lives and work through the analysis of responds; they eat food for their health and their health, lives or task.(Surely they family-centered structure. Third, 78% of 40s group responded that they enjoy finding good restaurants while 20s to 30s are enjoying fastfood and instant food instead of Korean traditional foods. fourth, health care by the exercise is done in one or half one hour and the dependant exercises like jogging or swimming which can be done whenever they have time are perferred to group exercise. It's desirable that one has to take care of himself with systematic and effective way. But it's very difficult and care for most people to take care of themselves, so they have to make the program and practice it systematically. The result from this study shows that practicing the health related program rationally, at the same time increasing leisure time and doing dependant or group exercise, taking a walk, and various kind of exercise considered spending money are more common than eating foods for health care. These are regarded as a desirable phenomenon in terms of the health care.

Purpose: The purpose of the present study was to compare the effects of both general hold-relax techniques and hold-relax techniques using pumping on pain due to delayed muscle pain and on the range of motion (ROM) of joints. Methods: Thirty-nine young adult males and females were randomly assigned either to a hold-relax technique application group of 20 subjects or to a group of 19 subjects with hold-relax techniques applied using a pumping application. Tenderness thresholds, the ROM of joints, and pain intensities were measured on the biceps of the nondominant arm of the subjects in both groups before exercises were performed to induce delayed muscle pain. Tenderness thresholds were again measured 24hours, 48hours, and 72 hours after inducing delayed muscle pain. The relevant intervention methods were applied to the two groups after conducting the measurement at 48hours. As a statistical analysis method, repeated measure ANOVAs were conducted to examine the tenderness thresholds, ROMs of elbow joints, and pain intensities in the individual groups at the time points. Results: At 48 hours and 72 hours after application of the interventions, the general hold-relax technique application group showed greater changes in the tenderness thresholds, the ROMs of elbow joints, and the pain intensities than did the group applying hold-relax techniques using a pumping application (p>0.05). Conclusion: Based on the results of the present study, the application of hold-relax techniques is thought to have beneficial effects on pain resulting from delayed muscle pain and on limited ROMs of joints.

Purpose: The aim of this study was to investigate the effects of coordinative locomotor training in a chronic stroke patient. Methods: A left hemiplegic patient diagnosed with a right middle cerebral artery stroke participated in this research. The patient's functional conditions were assessed, and a coordinative locomotor training program was initiated to resolve the problems identified. A set of movements deemed difficult based on the brief International Classification of Functioning, Disability and Health core set for stroke and d4501 (long-distance walking) were agreed as improvement targets. The program comprised warm up, main, cool-down, and home exercises. Repeated measurements were obtained, as follows: five times at baseline (A), 10 times during the intervention (B), and five times after the intervention (A). The study period was 7 weeks, and the intervention period was 1 h per day, twice a week for 5 weeks. Various tools, including the community walking test (CWT), 10-m walking test (10 MWT), 6-min walking test (6 MWT), and timed up and go (TUG) test, were conducted to assess the patient's walking ability. Changes in functional domains before and after the ICF Qualifier were compared. The mean values of the descriptive statistics were calculated, and a visual analysis using graphs was used to compare the rates of change. Results: The results showed that the CWT, 10 MWT, 6 MWT, and TUG test scores during the intervention period improved and that this improvement remained, even during the baseline period. In addition, the ICF Qualifier before and after the comparison decreased from moderate to mild. Conclusion: Based on the results, we propose that coordinative locomotor training can have positive effects on community ambulation of chronic stroke patients.

Background: Many previous studies recommended the side-lying hip abduction (SHA) exercise for targeting the gluteus medius (Gmed) and gluteus maximus (Gmax) muscle activity while the decreasing tensor fasciae latae (TFL) activation. Mischoice of hip position and angle in SHA may increase the risk of lower extremity injuries and undesirable muscle activation. However, information is limited on the effect of composite hip flexion angles and hip rotation on the gluteal muscle activity during SHA. Objects: This study aimed to compare muscle activity (Gmed, TFL, and Gmax) and activity ratios (Gmed/TFL, Gmax/TFL, and Gmed/Gmax) using surface electromyography (EMG) during SHA exercise at three different hip flexion angles either with or without internal rotation (IR) in subjects with Gmed weakness. We hypothesized that applying hip flexion and IR during SHA would increase gluteal muscle activity and decrease TFL activity. Methods: Muscle activity and activity ratios in 20 volunteers with Gmed weakness during 6 different SHA were investigated with surface EMG. One-way repeated-measures analysis of variance was used to determine the statistical significance. Results: Significant differences were found among the six different exercises for Gmed ($F_{2,41}=11.817$, p<.001) and Gmax ($F_{3,52}=5.513$, p=.003) muscle activity, and Gmed/TFL ($F_{3,54}=8.735$, p<.001) and Gmax/TFL ($F_{2,37}=4.019$, p=.028) activity ratios. Conclusion: Applying hip flexion is an effective method for increasing gluteal activity, and it elicits great Gmed/TFL and Gmax/TFL activity ratios during SHA in subjects with Gmed weakness.
