Background: The purpose of this study was to investigate the effect of pressure distribution on the both foots with gluteus medius muscle intensive strengthening exercise in 4week. Methods: The purpose of this study was to investigate the effect of gluteus medius muscles strengthening exercise on the pressure distribution of the foot in 20 healthy adults. Four gluteus medius muscles strengthening exercise programs were conducted three times a week for four weeks. The pressure distribution changed of the right and left foot parts of the experimental group and the control group were measured and analyzed. Results: There was a significant difference in F1, F2, M1, M2, and H1 among the pressure distribution of the right foot of the experimental group (p<.05). There was a significant difference in F1, M1, M2, H1 and H2 among the pressure distributions of the left foot of the experimental group (p<.05). There was a significant difference in H1 among the pressure distribution of the right foot of the control group (p<.05). There was no significant difference in the pressure distribution of the left foot region of the control group (p>.05). There was a significant difference in H1 among the pressure distribution of the right foot between the group (p<.05). There was a significant difference in M2, H1 among the pressure distribution of the left foot between the group (p<.05). Conclusions: In the healthy adults, it was confirmed that the application of the gluteus medius muscles strengthening exercise had an effect on the weight shift during the walking due to the overall foot balance and the pressure distribution change of the foot part.

Background: The serratus anterior (SA) muscle is one of the important muscles in the upward rotation of the scapula when the arm is raised. Insufficient muscle activity of the SA can cause deformation of the shoulder rhythm resulting in shoulder pathology. Objects: This study intends to compare SA and upper trapezius (UT) activity during the conventional wall-slide and push-up plus exercises for SA muscle strengthening and the scapular upward rotation (SUR) exercise. Methods: A total of 30 subjects participated in this study, and we measured the muscle activity of the SA and UT muscles during the wall-slide, push-up plus and SUR exercises. The one-way repeated ANOVA was used to compare SA and UT muscle activities during the 3 exercises. Results: During the SUR exercise, SA muscle activity was 79.88% maximum voluntary isometric contraction (MVIC), which was significantly higher than its activity during the other 2 exercises. The UT muscle activity was 47.53 %MVIC during the SUR exercise, indicating a significantly higher UT muscle activity than during the other 2 exercises. Conclusion: These findings suggest that the SUR exercise can maximize SA muscle activity to strengthen the SA while keeping UT muscle activity at an appropriate level.

Temporomandibular joint osteoarthritis (TMJ OA) causes destruction of the temporomandibular joint (TMJ) and can lead to occlusal changes such as anterior open bite in some patients. Consequently, these patients may experience difficulty in chewing food items and exhibit abnormal functional habits such as bruxism, preventing healing of the TMJ condyles. Treatment protocols include the use of traction appliances to reduce stress on the condyles. Unstable occlusions can lead to weakness of the masticatory muscles which, in turn, worsen the occlusal changes and complicate pain management. Therefore, the current study evaluated the condition of the masseter muscle using ultrasonography and educated patients on the execution of gum-chewing exercises for muscle strengthening. It also aimed to assess the effects of traction appliances and strengthening exercises on the masticatory muscles of patients with occlusal changes caused by TMJ OA.

Purpose: This study aimed to verify the effects of a swallowing training program on swallowing function and depression for nursing home residents with dysphagia after stroke. Methods: This is a quasi-experimental study with non-equivalent control group pre-post test design. The program (oro-facial muscle strengthening exercises, swallowing exercises, expiratory muscle strengthening exercises, and brain stimulation exercises) applied to the experimental group three times per week for eight weeks, 40-45 minutes for each intervention. The final data from 42 people (21 experimental and 21 control) were analyzed by SPSS/WIN 25.0 using descriptive statistics. 𝜒² test, t-test, Wilcoxon rank sum test, and Friedman test. Results: The experimental group was significantly improved than control group in oro-facial muscle strength, swallowing symptoms (Z=-2.22, p=.026), and oral intake function level (Z=-2.00, p=.046). However, there was no significant difference between two groups in depression. Conclusion: This study is meaningful in that it reorganized and mediated a swallowing training program as a safe, non-invasive exercise that nurses can implement in a nursing facility with limited medical personnel and it could be easily followed by older adults.

Background: Squatting is one of the best functional exercises to strengthen the quadriceps muscle in independent gait and activities of daily living. Although the use of a gym ball during squat exercise is the most common way of strengthening the vastus medialis oblique (VMO) muscle, published data on this subject are limited. Objects: The purpose of this study was to compare the sequential muscle activation of the VMO and vastus lateralis (VL) muscles during squat exercise using a gym ball at different knee flexion angles. Methods: Forty healthy adults were randomly divided into experimental (squat exercise using a gym ball) and control (squat exercise alone) groups, in which squats were performed at $45^{\circ}$ and $90^{\circ}$ knee flexion. Electromyographic (EMG) activity data were collected over 10 seconds under the 2 angles of knee flexion ($45^{\circ}$ and $90^{\circ}$). Results: There was significant group and time interaction effect for VMO and VL muscle activation at $45^{\circ}$ knee flexion. This was similarly demonstrated at $90^{\circ}$ knee flexion. No significant group main effect and time main effect for VMO and VL muscle activation were noted at $45^{\circ}$ knee flexion, respectively. In contrast, there was significant group main effect and time main effect for VMO and VL muscle activation at $90^{\circ}$ knee flexion. These significant differences were demonstrated through two-way analysis of variance over repeated measurements, suggesting that the EMG activity of the VMO muscle during squatting with a gym ball showed remarkable improvement compared to that of the VL muscle. Conclusion: This research suggests that squat exercise using a gym ball may be more beneficial in improving the activity of VMO than of the VL muscle at both $45^{\circ}$ and $90^{\circ}$ of knee flexion, respectively. We highly recommend squat exercises with a gym ball for selective strengthening of the VMO muscle in knee rehabilitation.

Purpose : The purpose of the study was to examine if a respiratory muscle strengthening training in patients with stroke can improve their pulmonary function. Methods : Volunteers were included for the study if a patient diagnosed stroke more than 6 months and had 24 points or higher in MMSE-K scores. Twenty-eight subjects participated in this study and were randomly divided into two groups; a breathing exercise group(n=14) and a control group(n=14). The intervention for all subjects was conducted for 20minutes, three times a week for 4 weeks. Subjects for the breathing exercise group had the respiratory muscle strengthening training using spiro-tigers, where-as subjects in the control group got their usual treatment ie a postural training. The six-minute walking test(6MWT) and the pulmonary function tests(FVC, $FEV_1$, $FEV_1$/FVC, VC, Vt, IRV and ERV) were employed to assess treatment effects at baseline and after their intervention. Results : Twenty-four subjects finished their 4-week treatment programs. The general characteristics between groups were found to be similar (p>0.05). The pulmonary function between groups were also observed no difference across groups at the baseline measurement (p>0.05). In the post treatment group comparison, subjects in the breathing exercise group showed an increase in lung function with VC ($2.73{\pm}0.80{\ell}$) and Vt ($0.87{\pm}0.38{\ell}$) than those in the control group ($1.91{\pm}0.80{\ell}$ and $0.48{\pm}0.22{\ell}$ respectively) (p<0.05). However, there was no difference found in 6MWT, FVC, $FEV_1$, $FEV_1$/FVC, IRV, and ERV across groups (p>0.05). Conclusion : A significant increase in VC and Vt was found in subjects with stroke, who had four-week training on respiratory muscle strengthening. However, respiratory muscle strengthening showed no effect on walking speed and FVC, $FEV_1$, $FEV_1$/FVC, IRV, and ERV in patients with stroke.

Purpose: This study examined the effects of a shoulder-strengthening exercise on muscle strength of shoulder flexors and extensors of caregivers. Methods: The study consisted of 19 caregivers (2 males and 17 females) employed by Medical Center B. All the participants took part in an 8-week shoulder muscle strengthening exercise, based on previous studies. In the first week, the subjects took part in a stretching exercise enhance the range of motion. In the second week, they participated in an exercise aimed at improving shoulder blade stability. From the third to seventh weeks, a resistance exercise of different intensities was applied in a phased manner. Finally, in the eight week, the subjects took part in plyometric exercise. Peak torque, average power, and total work of shoulder flexors and extensors in both sides were measured before and after the exercise at an angular speed of 120deg/sec using an isokinetic device. Wilcoxon's singed-ranks test was conducted to analyze differences in muscle strength before and after the intervention. Results: After the exercise, there was a significant improvement in peak torque and average power of flexors of the right arm. After the exercise, peak torque, total work, and average power showed a significant improvement in the flexors of the left arm (p<0.05). However, there was no statistically significant difference in extensor muscle strength in either arm after the exercise. Conclusion: Shoulder flexors of caregivers are utilized frequently in the workplace. Implementation of extensor-strengthening exercises, in addition to flexor-strengthening exercises, can contribute to reducing the incidence rate of shoulder injuries among caregivers.
