PURPOSE: This study examined the effects of different external loads on the muscle activities around the hip during prone hip extension with knee flexion (PHEKF) exercise in healthy young men.
METHODS: Sixteen healthy adult males participated in the study. A pressure biofeedback unit was used to provide feedback to the participants during the abdominal drawing-in maneuver (ADIM) with PHEKF. Sandbags (0 kg, 1 kg, 2 kg, and 3 kg) were used to provide external resistance. The quadriceps was contracted to maintain knee flexion 90° against resistance. Each resistance condition using a sandbag weight was given in random order. Surface electromyography (sEMG) was used to measure the electrical activity of the gluteus maximus, biceps femoris, and erector spinae during PHEKF.
RESULTS: The muscle activity of the gluteus maximus was highest with the 3 kg resistance and lowest with 0 kg (F = 128.46, P = .00). The muscle activities of the biceps femoris and erector spinae were highest with 0 kg and lowest with 3 kg (F = 29.49, P = .00). The muscle activity rate of the gluteus maximus/biceps femoris was highest with 3 kg and lowest with 0 kg (F = 37.49, P = .00).
CONCLUSION: The activity of the gluteus maximus was increased using a higher external weight load during PHEKF, while the activity of the biceps femoris decreased. These findings suggest that an external weight is needed during hip extensor exercise to strengthen the gluteus maximus and inhibit the biceps femoris.

PURPOSE: This study examined the effects of posture improvement exercise using virtual reality programs on the posture and balance of patients with forward head postures.
METHODS: Thirty men and women in their 20 s, who had a forward head posture, were divided randomly into a group with posture correction exercise and a group with posture correction exercise combined with virtual reality programs. The posture correction exercise was composed of squats, XCO training, and chin-tuck exercise. In contrast, exercise with virtual reality games involved the Hot Squat, Climbey, and Baskhead programs while wearing a headset. Both groups performed the exercises 15 min a day, three times per week, for four weeks. The balance ability, distance between the acromion and earlobe, and neck joint range of motion were assessed before and after the exercises.
RESULTS: Both groups showed significant reductions in the distance between the acromion and the earlobe, along with significant improvements in the range of joint motion. The group that performed the virtual reality exercises showed a significant increase in the limit of stability. Both groups showed a significant decrease in the sway length. In contrast, the group given the virtual reality exercises showed a significant reduction in the sway speed while standing with their eyes closed.
CONCLUSION: Exercise applying virtual reality programs can be used in clinical and home programs to correct the postures of individuals with a forward head posture because they can trigger interest in inducing active participation.

PURPOSE: The purpose of this study was to examine the effects of dual-task training with cognitive tasks on cognitive functions and β-amyloid levels in the elderly with mild dementia.
METHODS: The subjects were 36 elderly inpatients diagnosed with mild dementia at S Hospital located in Gyeongsangbuk-do, South Korea. The patients were randomly divided into a dual-task training group (DTG; n = 18) or a single-task training group (STG; n = 18). DTG performed dual-task training with cognitive tasks while STG performed only exercise tasks. These groups performed their respective exercises during a 30-minute session occurring three times a week over an 8-week period. MMSE-K and GDS were used to measure the subjects' cognitive function. To assess the subjects' dementia-related factors, their β-amyloid levels were measured by blood analysis.
RESULTS: The results of the experiment were as follows: DTG showed statistically significant differences between their MMSE-K scores and β-amyloid levels before and after training (p < .05), whereas they exhibited no statistically significant differences in their GDS scores. MMSE-K scores and β-amyloid levels were significantly different between DTG and STG after training.
CONCLUSION: The present study's overall results indicate that dual-task training with cognitive tasks is more effective than single-task training in improving cognitive functions and β-amyloid levels in the elderly with mild dementia. In other words, regular dual-task training can be considered as effective in improving cognitive function and dementia-related factors in the elderly with mild dementia and thus may be suggested as an effective exercise method for the treatment and early prevention of dementia.

PURPOSE: The aim of this study is to find a more efficient intervention method through a study of the gait variables and dynamic balance of chronic neck pain patients.
METHODS: Forty subjects aged between 40 and 60 years were allocated randomly to two groups; The first group performed PA (Posteroanterior Mobilization), and the second group conducted CCF (Craniocervical Flexion Exercise). The gait variability measured the speed, cadence, and dynamic balance in the forward, leftward, rightward, and rearward directions. An independent t-test, Wilcoxon signed-rank test, and paired t-test were used for statistical analysis.
RESULTS: In the dynamic balance measurements, the variability of PA (p < .000) and CCF (p < .000) in the rightward direction, PA (p < .004) in leftward direction and forward direction increased significantly (p < .013). In an analysis of the gait variability, the cadence increased significantly in the PA group (p < .022) and not significantly in the CCF group (p < .056). On the other hand, there was no increase in the speed variable, in the PA group (p < .437). In the CCF group, the cadence increased significantly (p < .022). The differences in the PA and CCF group differences were not significant.
CONCLUSION: The PA group showed a significant increase in the forward (p < .013), leftward (p < .004), and rightward directions (p < .000). Speed was significant in the CCF group, and cadence was significant in the PA group. The dynamic Balance was effective in the rightward direction in both groups, but there was no significant difference between the two groups.

PURPOSE: This study examined the effects of integrating transcutaneous electrical nerve stimulation into treadmill gait training by applying functional electrical stimulation on the spasticity, balance, and gait ability of chronic stroke patients
METHODS: Twenty participants were assigned randomly to two groups: the treadmill gait training group with applied functional electrical stimulation (FES) with integrated transcutaneous electrical stimulation (TENS) (experimental group, EG, n = 10) and the treadmill gait training group with FES (control group, CG, n = 10). Both groups received treadmill gait training with FES for 30 minutes a time, four times a week, during five weeks. The experimental group received additional TENS on their L3, L5, and S2 dermatome for 30 minutes before the interventions. The spasticity, balance, and gait ability were evaluated before and after the training to compare the intergroup and intragroup changes.
RESULTS: Both groups showed significant improvements in the static, dynamic balance, and gait ability (p < .05), but did not show any significant changes in the muscle tone. The EG showed significant improvements in the static balance ability and gait cycle compared to the CG (p < .05).
CONCLUSION: Treadmill gait training combined with FES with integrated TENS is an effective method for improving the static balance and gait cycle. On the other hand, the effects of treadmill gait training with FES on spasticity need to be studied further.

PURPOSE: This study examined the difference in muscle activity of the trunk and legs during flat walking with or without an abdominal drawing-in maneuver.
METHODS: This study was conducted on 15 healthy males and eight females who were attending D University in Busan. This experiment was conducted after 15 minutes of abdominal drawing-in training using a pressure biofeedback unit before the experiment, and the difference in the muscle activity of the trunk and legs during flat walking with or without an abdominal drawing-in technique was investigated. Surface electromyography was used, and the electrode attachment site was the right sternocleidomastoid muscle, splenius capitis muscle, rectus abdominis muscle, external abdominal oblique muscle, transverse abdominis muscle, erector spinae muscle, vastus medialis muscle, and vastus lateralis muscle (TM DTS, Noraxon, USA). The data were analyzed statistically using a paired t-test on SPSS version 18.0 (IBM).
RESULTS: The muscle activity of the rectus abdominis muscle, external abdominal oblique muscle, transverse abdominis muscle, vastus medialis muscle were increased significantly and maintained more than walking without maintaining an abdominal drawing-in maneuver (p < .05). Moreover, muscle activity of the erector spinae muscle was decreased significantly and maintained more than walking without maintaining an abdominal drawing-in maneuver (p < .05).
CONCLUSION: Maintaining an abdominal drawing-in maneuver during flat walking is more effective during walking training.

PURPOSE: This study examined the incidence, location, and characteristics of sports injuries according to the position in Korean national Kabaddi athletes.
METHODS: Twenty-four national Kabaddi athletes (12 males and 12 females) who trained at the national training center between January 2019 and December 2019 were enrolled in this study. The event, position, and location of injury were recorded on an IOC daily injury report form. The incidence of sports injury was examined with the 95% confidence interval (CI), and the difference in the incidence of injury by position was presented as the rate ratio (RR). Moreover, the differences in the location of sports injury according to position were examined using χ2 tests.
RESULTS: One hundred and nine sports injuries occurred among Kabaddi players, with an incidence of 20.28 cases of injuries per 1,000 exposures (95% CI 16.47 - 24.08), and the incidence of injury was the highest among the competition, followed by training and weights. The most common location of sports injury was the lower extremity, followed by the upper extremity, trunk, head, and neck. In addition, no significant differences in the locations of the sports injuries were noted according to gender (p = .689). Furthermore, knee, ankle, lumbar spine/lower back, shoulder/clavicle were common sites of sports injury among Kabaddi players.
CONCLUSION: These results provide a baseline for predicting sports injuries occurring in athletes during games, and would provide useful information for developing performance enhancement as well as injury prevention programs.

PURPOSE: This study examined the effects of coordinative locomotor training on the physical factors for falls in the elderly with mild cognitive impairment.
METHODS: This study examined thirty subjects diagnosed with mild cognitive impairment by the radiologic findings, history, and physical examination. The subjects were assigned to a control group (n = 15) or experimental group (n = 15, coordinative locomotor training). The experimental group underwent coordinative locomotor training for four weeks, with training sessions two times per week. The control group was given a fall-prevention education for 60 minutes without coordinative locomotor training. To evaluate the physical factors for falls, the lower extremity strength and the Korean version of the Fullerton advanced balance scale and biorescue were measured for balance. These tests were conducted before and after training.
RESULTS: Significant differences were observed between the two groups after the four weeks of coordinative locomotor training for the elderly with mild cognitive impairment the experimental group had a greater degree of improvement in the physical factors for falls.
CONCLUSION: These findings suggest that coordinative locomotor training may have a functional effect on fallprevention and the mobility of the elderly with mild cognitive impairment. In addition, it is expected to provide systematic and effective data that can be used as a fall prevention program for the elderly with mild cognitive impairment in each institution.

PURPOSE: The purpose of this study was to investigate the effect of taping method using elastic tape and non-elastic tape on pain, grip strength and muscle activity in middle-aged female patients with lateral epicondylitis.
METHODS: The subjects were 40- to 50-year-old female patients with lateral epicondylitis. A total of 22 subjects were divided into two groups, and each group had 11 patients. The intervention was carried out three times a week for 4 weeks. One group applied tape using elastic tape (ETG) while the other group applied tape using non-elastic tape (NETG). The measurement factors were pain, grip strength, and muscle activity. Pain was measured using VAS. Grip strength was measured using a grip dynamometer, and muscle activity was measured using EMG in the affected extensor carpi radialis brevis. Changes in interventions were compared among the groups using a paired t-test. The comparison between groups compared delta values (Changed values) between pre- and post-intervention using an independent t-test.
RESULTS: In both groups, there was a statistically significant decrease in VAS. However, there was no statistically significant decrease in the delta value of VAS between ETG and NETG. In both groups, grip strength and muscle activity increased after intervention. There were statistically significant differences in delta values between ETG and NETG.
CONCLUSION: Taping is a good intervention method for patients with lateral epicondylitis. Both elastic tape and non-elastic tape were effective. In particular, taping using elastic tape is an effective method for improving muscle function with pain reduction.

PURPOSE: Postural and structural asymmetry due to muscle imbalances around the lower back and pelvis are the causes of back pain. Muscle imbalances in patients with chronic low back pain affect the pelvic tilt and movement, and it is necessary to assess the pelvic movement ability using the appropriate tools to determine the mediating effects of lower back pain. This paper reports the reliability and validity of the Sensbalance Therapy Cushion (STC) for pelvic movement and proprioception.
METHODS: In this study, the Wii balance board (WBB) was used as a golden standard for pelvic movement measurements. FABQ, KODI, Myovision, and Pelvic movement were measured in 50 patients with chronic low back pain. The correlation between the lower-back muscle activity and pelvic movement was checked. The pelvic movement parameter was measured twice to determine the intra-rater reliability.
RESULTS: The STC showed high test-retest reliability in the pelvic tilt measurements (ICC = .672 - .809). The testretest reliability of proprioception measurements (ICC = .588 - .859) and reaction time measurements (ICC = .542 - .836) were also high. The relationship between the WBB and STC showed a significant positive correlation with the pelvic tilt test (p < .01). The posterior pelvic tilt and lower-back muscle activity showed a significant negative correlation (p < .01). The pelvic left tilt and lower-back muscle activity showed a significant negative correlation (p < .05).
CONCLUSION: The results revealed the high reliability and validity of the STC. Therefore, the STC can be used as an objective measuring device for evaluating pelvic tilt, proprioception, and reaction time in low back pain patients.
