Background: Degenerative arthritis accounts for a large portion of the elderly, causing a lot of inconvenience in daily life. Total knee replacement (TKR) are performed to relieve pain in the knee joint. The purpose of this study was to determine whether knee joint stabilization exercises are effective in improving balance and walking ability in degenerative arthritis patients who have undergone TKR. Methods: A total of 30 TKR patients participated in this study. They were assigned to two groups. The experimental group, the group that underwent knee stabilization exercises, joint mobilization and general physical therapy. On the other hand, and the controlled group, the group that underwent joint mobilization and general physical therapy. All exercises were conducted thrice a week, for four weeks. The main balance outcomes were evaluated using the posture balance training system, while walking ability was assessed using a wireless 3-axis accelerometer. Results: The experimental group had significantly higher scores in postural stability testing (PST), limits stability testing, and waling ability. The post-intervention evaluation, there were significant differences in all variables between the two groups. However, no significant difference was noted in the foam eyes closed test in PST. Conclusion: This study suggests that knee joint stabilization exercises effectively improve the balance and walking ability of TKR patients. Thus, it could be presented as useful in clinical practice.
Purpose: The purpose of this study was to determine the effects of contract relaxation and a combination of isotonics in proprioceptive neuromucular facilitation (PNF) on hip and lumbopelvic motions of male patients with chronic low back pain. Methods: As the subjects of this study, a total of 45 male patients with chronic low back pain were divided into groups: 15 who underwent contract relaxation (CR) of the PNF of their hip joints, 15 who underwent a combination of isotonics (CI) of the PNF, and 15 who underwent both techniques. A device for analyzing three-dimensional motion was used to measure hip medial rotation angles, lumbopelvic rotation angles, and hip medial rotation angles at the start of lumbopelvic rotation during hip medial rotation. A two-way repeated measures ANOVA was used to compare the average values. Results: There were interactions in the hip medial rotation angles, lumbopelvic rotation angles and hip medial rotation angles at the start of lumbopelvic rotation based on the methods and periods of exercise (p < 0.05). The CR and the CR+CI groups displayed more increased hip medial angles when compared to the CI group. The CR+CI group had more decreased lumbopelvic rotation angles when compared to the CR and the CI groups. The CR+CI group had more increased hip medial rotation angles at the start of lumbopelvic rotation when compared to the CR and the CI groups. Conclusion: It can be concluded that the combination of stretching and stability exercises was effective in male patients with chronic low back pain who showed limited hip medial rotation.

Purpose : The purpose of this study is to compare muscle activity after applying two muscle energy techniques (MET) to subjects with forward head posture to see if the post isometric relaxation (PIR) technique is more effective than the reciprocal inhibition (RI) technique. Methods : The muscle activity was measured using EMG after applying the PIR and RI techniques to 30 adults at K College. Subjects were selected for forward head posture whose ear center was 2.5 ㎝ front of the center of the shoulder. EMG equipment was used to measure muscle activity, and the measurement sites were measured in cervical flexor and extensor muscles. The experiment period was performed once a week for a total of two weeks, and after the pre-measurement was performed for 5 minutes PIR and RI exercise. In the PIR technique, the head is tilted back in a sitting position, and the experimenter applies resistance with the same force for 7~10 seconds and repeats 3-5 times after rest. In the RI technique, in a sitting position, the subject gives the force to bend the head forward, and the experimenter applies resistance with the same force for 7 to 10 seconds, and repeats 3 to 5 times after rest. Results : The result is same as the following. In the comparison of muscle activity, there was a significant decrease in both PIR and RI at 1 and 2 weeks. And there was a greater decrease in muscle activity in PIR. There was no difference in the comparison of decrease in muscle activity at 1 week and 2 week. Conclusion : Both PRI and RI can be said to be effective in improving the function of the forward head posture in the neck muscles. Therefore, the selection of the two techniques in clinical practice should be appropriately performed under the judgment of experts according to the patient's situation.

Purpose: The purpose of this study was to determine how a shoulder complex stabilization exercise affects ball control and ball speed in elementary school baseball players with an instable scapula. Methods: The subjects of the study were 16 baseball players attending S elementary school in Kwangju Metropolitan City. A shoulder complex stabilization exercise was conducted three times per week for one hour for four weeks. Then, the participants were divided into a scapular instability group or stability group based on their lateral scapular slide test scores. The measurement tool was measured using the target, the ball speed tester (PR1000-BC). All inspections were measured before and after the mediation period to examine the change in the subjects according to the mediation period. Results: As a result of measuring ball control, there was a statistically significant difference in the variation over time (p < 0.05), and there was no statistically significant difference in the interaction between time and group (p > 0.05). As a result of the test of effectiveness between subjects, there was no statistically significant difference found among the groups (p > 0.05). In terms of ball speed, there was no statistically significant difference found in the variation over time (p > 0.05) as well as in the interaction between time and group (p > 0.05). In terms of the effectiveness between subjects, there was no statistically significant difference found among the groups (p > 0.05). Conclusion: It was found that the shoulder complex stabilization exercise could improve ball control for elementary school baseball players. It is believed that this will help prevent and solve possible sport damages experienced during training or competitions, thereby helping athletes use training methods to improve their exercise capacity and continue their careers.

The purpose of this study was to investigate the effect on the activity of the upper trapezius and erector spinae according to the length difference of the backpack using electromyogram (EMG). We also conducted a study comparing the center of pressure (COP) and weight distribution before and after using Wii® balance board. Thirty individuals were randomly assigned to the experimental group (n=14) wearing a backpack with a short right strap length and a control group (n=16) wearing a backpack with the same strap length. Data were collected by dividing into groups, carring a 15% weight backpack and walking for 20 minutes on a treadmill. As a result of analyzing the EMG data, there was no significant change in the upper extremity muscle activity of the control group, but it was significantly decreased in the right upper trapezius activity of the experimental group (p<0.05). In addition, there was a significant change of COP in the experimental group (p<0.05), but there was no significant difference of the weight distribution in both groups. Recognizing mechanical changes in the body that may occur due to the asymmetry of the strap length is thought to be helpful for systematic ergonomic intervention according to changes in the external environment in the future.

Background: This study compared the effects of trunk stabilization exercise and hip joint exercises on the range of motion of the lumbar spine, pain severity, and severity of disability in patients with chronic lower back pain. Methods: A total of 30 participants were enrolled and divided into group 1 (n=10), group 2 (n=10), and group 3 (n=10) were performed by each group thrice a week for a total of 8 weeks. Group 1 performed warm-up exercise (15 min), trunk stabilization exercise (25 min), finish-up exercise (15mins). Group 2 performed warm-up exercise (15 min), hip exercise (25 mins, finish-up exercise (15mins). Group 3 warm-up exercise (15 min), trunk stabilization and hip exercise (25 min), Finish-up exercise (15 min). Participants were assessed for the range of motion of the lumbar spine, pain severity (visual analog scale score; VAS), and severity of disability (Oswestry disability index score; ODI) before and after the interventions. Results: All three groups showed a significant increase in the range of motion of the lumbar spine, but there was no significant difference among the groups. Moreover, the severity of pain and ODI were significantly decreased in all groups; however, the intergroup differences were non-significant. Conclusion: The results from this study confirmed the effectiveness of trunk stabilization and hip joint exercise in improving the lumbar range of motion, pain severity, and chronic lower back pain in patients. Thus, trunk and pelvic stabilization exercises and hip joint exercise can be used as clinical practices to treat and prevent chronic lower back pain.

Background: This study examined the effects of adding fibular repositioning taping (FRT) to ankle mobilization with movement taping (AMT) on the ankle range of motion (ROM), balance, and gait performance in patients with chronic stroke with limited ankle dorsiflexion. Methods: The participants were randomized into the control (n=15) and AMT+FRT groups (n=15). The control groups applied only non-elastic taping on the affected ankle, and the AMT+FRT groups also applied non-elastic taping to the inferior tibiofibular joint. Both groups performed treadmill walking for 10 minutes. The ankle dorsiflexion passive ROM, balance, gait velocity, and cadence were measured before and after the intervention. Results: Both groups showed a significant difference after the intervention in the dorsiflexion ROM (p<.01), balance (p<.01), and gait performance (p<.01). On the other hand, no significant difference was observed between the two groups (p>.05). Conclusion: AMT improved ankle dorsiflexion passive ROM, balance, gait velocity, and cadence in patients with chronic stroke, but there was no difference between the two groups. Therefore, the addition of FRT to AMT does not influence the ankle dorsiflexion ROM, balance, and gait performance in patients with chronic stroke.

Background: There is still controversy as to whether hip external rotation and dorsiflexion selectively activate the vastus medialis obliquus (VMO) during straight leg raise exercise. Due to the anatomical characteristics, hip adduction must be preceded to activate the VMO. In this study, the activities of the rectus femoris (RF), vastus lateralis (VL), VMO were measured by adding the hip adduction movement to the straight leg raise exercise with hip 45° external rotation and straight leg raise exercise with hip 45° external rotation and dorsiflexion. Through this, we want to find out whether the VMO is selectively activated. Methods: Thirteen healthy participants performed straight leg raise exercise with hip 45° external rotation, straight leg raise exercise with hip 45° external rotation and dorsiflexion, straight leg raise exercise with hip 45° external rotation and adduction, straight leg raise exercise with hip 45° external rotation and adduction and dorsiflexion was randomly performed. Through this, EMG data of the RF, VL, VMO were collected. Results: During the straight leg raise exercise, hip adduction increased the activity of the VMO and VL, no significant difference was found(p>.05). However, in the VMO/VL ratio, straight leg raise exercise with hip 45° external rotation and adduction and dorsiflexion activated the VMO and the VL at a ratio of about 1:1, It showed a significantly higher rate than straight leg raise exercise with hip 45° external rotation(p<.05). Conclusion: During the straight leg raise exercise, hip adduction is considered to be an important movement that can selectively induce the activity of the VMO. Therefore, follow-up studies on this should be conducted.
