The purpose of this study was to examine the effects of the thoracic spine manipulation on spinal alignment (Cobb angle), pain, and trunk range of motion (ROM) in a patient with mild thoracic scoliosis. The Cobb angle was 11.0° and there was a right deviation of the thoracic spine. The subject had thoracic and lumbar pain, and had felt stiffness during turning of the trunk for about 3 years. Thoracic manipulation was applied at the upper thoracic spine as a therapeutic intervention three times per week for 5 weeks. After intervention, the Cobb angle decreased from 11.0° to 5.5° and the pain score decreased from 4.0 to 1.5, and the trunk left rotation ROM increased from 30.0° to 41.5°, and trunk right rotation ROM increased from 26.0° to 39.0°. These results suggest that the thrust thoracic manipulation technique had a positive effect on the spinal alignment, pain and trunk rotation ROM in patients with mild scoliosis.
The main focus of this study was to create canine skeleton modeling files and real-world structures for canine kinesiology and physical rehabilitation education. Firstly, 3-dimensional (3D) modeling was conducted with additional reverse engineering process, and then directly fabricated the files. In other way, we made multi-joint based canine structure using conventional corrugate tube. This study indicated that the final real-world structures could contribute to improve initial movements of canine rehabilitation or academic filed of kinesiology in Korea.
The purpose of this study was to investigate the effects of squat exercises with an upper limb resistance movement on the vastus medialis oblique, vastus lateralis, and gluteus maximus. This study recruited 16 healthy men. All subjects performed squat exercises with and without upper Limb resistance movements by using elastic tubing band. Electromyography (EMG) activity of the vastus medialis oblique, vastus lateralis, and gluteus maximus was recorded using a surface EMG system during these isometric squat exercises in both experimental conditions. The different muscle activation of the vastus medialis oblique, vastus lateralis, and gluteus maximus between the squat exercises with and without the upper limb resistance movement was analyzed using a paired t-test or Wilcoxon signed rank test. Our findings showed that the vastus medialis oblique, vastus medialis oblique/vastus lateralis ratio and gluteus maximus muscle activity was significantly increased during the squat exercise with upper limb resistance movements, as compared to the squat exercise without this component (p < .05). Based on our findings, the additional upper limb resistance movement may be a useful strategy to facilitate the vastus medialis oblique and gluteus maximus muscle activation during a squat exercise.
The purpose of this study was to measure the mean peak mobilization forces to the cervical spine 3-5 with grade III and grade IV of posteroanterior (PA) mobilization. Asymptomatic 25 college subjects were participated in the trial and eligible physical therapists performed cervical mobilization. The mean peak mobilization force was measured during the PA mobilization with grade III and grade IV by attaching a flexible force transducer over the C3-C5 spinous process. Three cycles of PA mobilization were performed in each spine and the therapist took approximately 2.5s to complete mobilization. After applying the grade III mobilization to the C3-C5, 30 minutes later, the grade IV mobilization was applied to the same area again. There were no significant differences between C3, C4 and C5 during grade III as well as grade IV. Upon comparing the mean peak force of grade III with mean peak force of grade IV at the C3, C4 and C5 respectively, an insignificant difference was also observed. The mean peak mobilization force was 4.53±1.79 N at the C3, 5.10±1.91 N at the C4, and 5.17±2.63 N at the C5 during grade III force was applied. The mean peak mobilization force was 4.40±1.56 N at the C3, 5.53±2.01 N at the C4, and 5.38± 2.73 N at the C5 during grade IV force was applied. This study suggested that the mean peak force of the grade III and grade IV mobilization in the C3-C5 was similar each other, also there was no difference between mean peak force of grade III and grade IV on C3, C4 and C5.
The purpose of this study was to measure the mean peak mobilization forces to the lumbar spine 1-3 with grade III and grade IV of posteroanterior (PA) mobilization. Twenty subjects with no history of Lumbar back pain (LBP) (10 female, 10 male) with a mean age of 24.1 years (SD = 6.0) were recruited for the study and PA mobilization were performed in each spine and the therapist took approximately 2.5s to complete mobilization. In the results, applied grade IV force showed no different according to each segment in LS1, LS2, LS3, however, there are distinct differences between LS1 and LS2, LS1 and LS3 during mobilization with grade III force. This study suggested that the mean peak force of the grade III and grade IV mobilization in the L1-L3 was almost similar each other.

This study investigated the effects of myofascial release therapy and massage on upper trapezius myalgia and sleep quality in 60 female and male individuals employed at casinos between the ages of 20-49. Subjects were divided into three groups: a myofascial release therapy group (n=20), a massage group (n=20), and a control group (n=20). Each intervention lasted 15 minutes and was performed 4 times a week for 4 weeks. Pain was significantly decreased after the application of myofascial release therapy and massage (p<.05), however slightly increased in the control group, and myofascial release therapy reduced pain a little more than massage. Sleep quality was also significantly increased by myofascial release and mass (p<.05), however only slightly in the control group. The findings of this study suggest that myofascial release therapy and massage are effective in improving upper trapezius myalgia and sleep quality in casino employees.
Purpose of this study is to describe the treatment, surgery, rehabilitation and return to daily life subject pectoralis major muscle rupture. The in patient with was a 26 years old, injured in training due to hyperextension and external rotation. Physical examination, manual test, and MRI were used to diagnose pectoral muscle rupture and operation took for the pectoralis major muscle rupture with allograft. The subject was referred for rehabilitation from 3 weeks. Range of motion (ROM) exercise was mainly performed until 3 months, strength was performed with tubing band, body weight, machine training and proprioceptive exercise. Shoulder range of motion (external rotation, flexion) were measured with goniometer and muscle strength (flexion, adduction, internal rotation) were measured with dynamometer. At 6momths, external rotation ROM was 50° (unaffected side 60°), and flexion almost recovered at 3 months. Muscle strength was gradually increased to 6.2kg, 15.7kg, and 27.0kg in flexion, while internal rotation The pain remained slightly after 9 months. The present results suggest that ROM exercise and strengthening exercise increase the muscle power and ROM, and decrease the pain.
The purpose of this study was to identify the effects of shoulder stabilization exercises and stretching on shoulder height and muscle activity in young adults with rounded shoulder posture. The subjects were young adults with rounded shoulder posture, and divided into two groups: shoulder stabilization exercises and stretching exercises. The shoulder stabilization exercise group performed Thera band exercises and stretching exercises. The stretching exercise group performed stretching exercises. The groups performed the exercises for 40min, three times a week for four weeks. Shoulder height was measure by Vanier calipers and muscle activity was measured by electromyography. Shoulder height was significantly decreased in both groups after intervention, however there was no difference between groups. There was a significant difference in muscle activity between the two groups after the intervention, however there was no difference between the groups. This study suggests that shoulder stabilization exercise and stretching affect shoulder height and muscle activity.

In the results of this study, posterior superior iliac spine (PSIS) alignment decreased significantly after use of the foot position adjuster and center pressure was significantly increased after use of the foot position adjuster. This study suggests that foot position adjuster influences body alignment and weight distribution.
The aim of the study was to investigate the effects of incentive spirometry and Ujjayi breathing technique on the pulmonary function of smokers. Subjects were individuals who had a smoking habit of at least a year. Subjects were randomly divided into 3 groups: the incentive spirometry group (n=8), Ujjayi breathing technique (n=9), and a group applying both incentive spirometry as well as Ujjayi breathing technique (n=8). Each intervention was performed twice a day, 5 times a week, for a total of 8 weeks whereupon the change in pulmonary function was evaluated. A spirometer was used to measure FVC, FEV1, and FEV1/FVC. The survey used for this study included the Fagerström Test of Nicotine Dependence (FTND) and the Shortness of Breath Questionnaire (SOBQ). Study results for the comparison within groups showed that in the group that performed both the incentive spirometry and Ujjayi breathing technique, FEV1 improved with statistical significance (p<.05). Furthermore, within this comparison the FEV1/FVC improved with statistical significance. Comparison amongst the groups showed no statistically significant differences in all areas. Following, to effectively increase pulmonary function in young adult smokers, both incentive spirometry and Ujjayi breathing technique should be employed together.

Side step was significantly different between Kendo player, Judo player, Judo player and Taekwondo player, Taekwondo player and Kendo player (p<0.05). This study suggests that systemic reaction, vertical jump and side step are different for each sport.
This study aimed to investigate the effect of smartphone size and use on fatigue of the extensor pollicis longus and abductor digiti minimi, and digiti minimi deformity. The 40 people assigned to the experimental group spent at least 6 hours using the smartphone and used the digiti minimi for support. The control group spent at least 3 hours using the smartphone, however did not use digiti mini for support. Questionnaires were used to measure smartphone usage, daily use duration, and method of holding the smartphone device. X-rays of distal interphalangeal joint angle deformity of the digiti minimi were assessed. Surface electromyography was used to analyze muscle fatigue. The angle deformity was significantly different between the experimental group and the control group, and fatigue of the extensor pollicis longus and abductor digiti minimi of the large smartphone users were high. The muscle fatigue was reduced when the smartphone size fit well with the user's hand. This study suggests that the size of the smartphone influence the fatigue of the hand muscles.
The purpose of this study was to identify the effect of chiropractic treatment on the alignment of the lower extremities and plantar pressure in subjects with pelvic misalignment. The study included 20 subjects with pelvic misalignment. They were divided into two groups: the chiropractic treatment group (n=10) and stretching group (n=10). They performed the intervention for 10 minutes, twice a week, for weeks, and pelvic displacement, functional leg length, and plantar pressure were measured In chiropractic group, both pelvic displacement and plantar pressure distribution were significantly decreased and leg length difference was significantly increased (p<.05). However, in the stretching group, only pelvic displacement was significantly reduced (p<.05), and leg length difference and plantar pressure distribution decreased slightly. There was no significant difference in all variables between the groups. This study suggests that chiropractic and stretching are effective in changing pelvic displacement, leg length difference, and plantar pressure distribution.
This study was conducted to compare the difference between left and right extension and flexion isokinetic muscular strength of the knee, shoulder, and trunk to compare absolute and relative strength in lightand heavy weight Ssireum athletes. Fourteen professional Ssireum athletes were divided into the light (Taebaek and Geumgang) and heavy (Halla and Baekdu) groups according to the body weight. Anthropometric measurements and isokinetic strength (knee: 60º/sec, shoulder: 30º/sec, and trunk: 30º/sec) were assessed for the absolute and relative peak torque values. Left (227.6±48.7 vs 247.0± 23.1 Nm, p=0.05) and right knee (233.7±32.0 vs 266.1±20.5, p=0.05) extension strength in absolute values were significantly different between the groups. Trunk’s extension (318.7±37.9 vs 351.2±57.4 Nm, p=0.03) and flexion (249.8±33.0 vs 302.1±42.4 Nm, p=0.03) strength also showed significant difference between the groups. Significant differences were observed for all relative values except for the left knee and trunk flexion. As for the flexion and extension strength ratios, the shoulder extension to flexion ratios of the light group was 1.32 (p=0.02) times and the heavy group was 1.01-0.98 (p=0.34). The trunk extension strength was 3.6 times that of the body weight in the light group and 2.8 times that of the body weight in the heavy group. Heavy Ssireum athletes’ absolute flexor peak torques were higher in the knee and trunk than in the light athletes. Also, the weight per weight of light athletes had relatively higher strength than the heavy athletes. In addition, the muscle strength ratio was higher in the light athletes. This study suggests that isokinetic strength is different in heavy and light weight class Ssireum athletes.
