Purpose: This study attempted to understand health behaviors and analyze the association of the health behaviors with musculoskeletal diseases in adults. Method: The subjects of this study were 6,946 adults aged between 20 and 65 who had participated in the 2001 National Health Nutrition Survey. The instrument was composed of Health Interview Survey (HIS), Health Behavior Survey (HBS) and Health Examination Survey (HES), which were used in the 2001 National Health Nutrition Survey. Data were analyzed using SPSS 10.1 by applying $x^2$ and multivariate logistic regression. Results: 1. The present smoking rate was 46.5% and the present drinking rate was 81.2%. 2. Of the subjects, 22.7% were overweight ($BMI{\geq}25$), and 28.1% were exercising regularly. 3. Major factors affecting musculoskeletal diseases were low education, poor economic state, smoking, and BMI. Middle school graduates were 2.54 times more likely to have musculoskeletal diseases than college graduates. The risk was 1.83 times higher in indigent respondents than in affluent ones, and 1.43 times higher in smokers than in non-smokers. Conclusion: Therefore, in order to reduce musculoskeletal diseases in adults, other various factors should be looked into, and public education about appropriate posture and exercise should be carried out in community. Additionally, concentrated intervention programs for patients with musculoskeletal diseases should be performed.

Purpose: The purpose of this study was to assess the effect of using smartphones for tele-rehabilitation on head position and neck dysfunction in workers with visual display terminal (VDT) syndromes over a four-week period. Methods: Sixteen VDT workers volunteered to participate in stretch exercise and posture education sessions. The subjects were divided into three groups as follows: five subjects in the visit group (VSG), six subjects in the video group (VEG), and five subjects in tele-rehabilitation group (TG). The subjects in all the groups performed the exercises three days per week for four weeks. Cranial rotation angle (CRA), craniovertebral angle (CVA) measurement, and neck disability index (NDI) tests were performed before and four weeks after the intervention. Results: No significant difference in the CRA and CVA variables was found among groups. No significant difference in the CRA variable was found within each group. A significant difference in the CRA variable was found in the VSG after the four-week intervention. No significant difference in NDI was found among the groups. The NDIs among all the groups were significantly decreased after the intervention when compared with the NDIs measured before the intervention. Conclusion: The use of smartphones in the tele-rehabilitation of VDT workers with neck pain was found to be as effective on neck function as the conventional intervention method. The tele-rehabilitation of VDT workers with neck dysfunctions may be presented as an alternative way.

The purpose of this study was to investigate the balance differences between skilled players and less-skilled players during Hakdariseogi motion of Keumgang Poomsae in Taekwondo. To achieve the study goal, total of 10 Taekwondo athletes; 5 skilled players(S, body mass: $67.0{\pm}5.7$ kg, height: $174.0{\pm}4.8$ cm, age: $20.0{\pm}2.0$ yrs) and 5 less-skilled players(LS, body mass: $73.0{\pm}4.9$ kg, height: $176.4{\pm}6.1$ cm, age: $20.8{\pm}1.3$ yrs) participated in this study. A three-dimensional motion analysis with 8 infrared cameras and one force plate whose sampling frequency as 30 Hz and 300 Hz, respectively, were performed. Participants' motion were divided into three phases which were preparation phase(P1), performing phase(P2) and maintaining phase(P3). The range and velocities of COP, the range and RMS of ground reaction torque and displacement between COM and center of BOS of each phase were computed. In this study, at P1 and P3 which were double and single stance, respectively, the range and M-L velocities of COP revealed significantly higher in LS compared with those of S(p<.05). At P2 which was single stance, LS indicated significantly higher in range of COP and ground reaction torque, and M-L velocities of COP than those of S(p<.05). The significantly shorter displacement between COM and center of BOS, however, was found in LS compared with that of S(p<.05). The results from our study indicated that S revealed more stable performance and a better posture control ability during performing Hakdariseogi motion.

Objective: This study aimed to identify the effects of performing shoulder and hip abduction during the V-sit exercise on abdominal muscle activity. Design: Cross-sectional study. Methods: Thirty healthy adults volunteered for this experiment. The participants randomly performed 6 types of V-sit exercises, including V-sit alone (hip 0°, shoulder 0°), V-sit with hip abduction 0° and shoulder abduction 15°, V-sit with hip abduction 0° and shoulder abduction 30°, V-sit with hip abduction 15° and shoulder abduction 0°, V-sit with shoulder and hip abduction 15°, and V-sit with shoulder abduction 30° and hip abduction 15°. EMG data were recorded from the rectus abdominis (RA), external oblique (EO), and internal oblique (IO) muscles of both sides. All abdominal EMG data during the six types of V-sit exercises were measured for 5 seconds, three times, and recorded for the middle 3 seconds excluding the 1 second at the start and end. Results: V-sit with shoulder abduction 30° resulted in significantly greater muscle activity of both RA, EO compared to shoulder abduction 0°, shoulder abduction 15° (p<0.05) and V-sit with shoulder abduction 15° showed significantly greater muscle activation of the RA compared with shoulder abduction 0° (p<0.05). The muscle activity of both EO and IO in the V-sit with hip abduction 15° was significantly greater than hip abduction 0° in all shoulder conditions (p<0.05). Conclusions: Greater angles of shoulder and hip abduction produced more abdominal muscle activity increases during the V-sit exercises. Shoulder abduction affected the RA, EO muscle activation and hip abduction affected the EO, IO muscle activation. This study showed that shoulder and hip abduction during V-sit exercises enabled effective activation of the trunk muscles.

Thoracic outlet syndrome is actually a collection of syndromes brought about by abnormal compression of the neurovascular bundle by bony, ligamentous or muscular obstacles between the cervical spine and the lower border of the axilla. First of all a syndrome is defined as a group of signs and symptoms that collectively characterize or indicate a particular disease or abnormal condition. The neurovascular bundle which can suffer compression consists of the brachial plexus plus the C8 and T1 nerve roots and the subclavian artery and vein. The brachial plexus is the network of motor and sensory nerves which innervate the arm, the hand, and the region of the shoulder girdle. The vascular component of the bundle, the subclavian artery and vein transport blood to and from the arm. the hand. the shoulder girdle and the regions of the neck and head. The bony, ligamentous, and muscular obstacles all define the cervicoaxillary canal or the thoracic outlet and its course from the base of the neck to the axilla or arm pit. Look at the scheme of this region and it all becomes more easily understood. Compression occurs when the size and shape of the thoracic outlet is altered. The outlet can be altered by exercise, trauma, pregnancy, a congenital anomaly, an exostosis, postural weakness or changes. Thoracic outlet syndrome has been described as occurring in a diverse population. It is most often the result of poor or strenuous posture but can also result from trauma or constant muscle tension in the shoulder girdle. The first step to beginning any treatment begins with a trip to the doctor. Make a list of all of the symptoms which seem to be present even if the sensations are vague. Make a note of what activities and positions produce or alleviate the symptoms and the time of day when symptoms are worst. Also, note when the symptoms first appeared. This list is important and should also include any questions one may have.

Background: Many studies have reported positive results of the various mirror training and virtual reality games in improving dynamic standing balance and posture adjustment in chronic stroke patients. However, no systematic study has been conducted to compare the effects of virtual reality games and the mirror balance training. Objects: The purpose of this study was to compare the effectiveness of Wii balance games and Mirror Self-Balancing Exercises in improving proprioception of knee joint and standing balance of people with chronic stroke. Methods: Twenty patients with chronic stroke volunteered for this study. The subjects were randomly divided into a Wii balance games group and a Mirror Self-Balancing Exercises group with 10 patients in each group. Each training was performed for 30 mins a day for 4 days. In addition to the balance training, 30 mins neuro-developmental-treatment based routine physical therapy was given to both groups. Proprioception was measured using two continuous passive motion devices, and static balance was measured using a Wii balance board. Dynamic balance assessment tools included the Berg Balance Scale, Dynamic Gait Index, and Timed Up-and-Go test. Results: All measured variables before and after the experimental results showed a significant improvement in both groups (p<.05). Only the improvement of the affected knee proprioception appeared to be significantly greater in the Wii balance game group (p<.05). However, other variables did not differ between the groups (p>.05). Conclusion: The findings suggest that both Wii balance games and Mirror Self-Balancing Exercises may be helpful for improving the proprioception of knee joint and the balance of patients with chronic stroke.

Purpose: This study examined changes in gait speed and stride length after an intervention involving simultaneous scapular and pelvic patterns of proprioceptive neuromuscular facilitation in a hemiplegic patient. Methods: A 58-year-old woman with left hemiplegia who had complained of slowness of gait speed and weakness of leg strength took part in an intervention involving scapular postdepression patterns on the affected side and pelvic postdepression patterns on the nonaffected side. The intervention was performed with the patient lying on her left side, in a half kneeling position, and in a standing posture. Rhythmic initiation was used for teaching the movements to the patient and improvement of kinesthesia, and a combination of isotonic was employed for increasing strength and irradiation of the scapula and pelvic movement. The intervention took place for 30 min. It was implemented twice a day, 5 days a week, for 3 weeks. After three repetitions, the average time taken to complete the 10-m walk test (10 MWT), in addition to stride length, was measured to determine gait speed. Results: After the 3-week program, the patient's performance in the 10 MWT improved from 21.7sec to 17.1sec, and her stride length improved from 31.4cm to 38.7cm. Conclusion: The results showed that trunk movement exercise, especially coordinative movements of the scapula and pelvis can improve gait speed and stride length by increasing trunk stability and mobility. A combination of pelvic and scapular patterns can facilitate trunk rotation, thereby improving gait speed and stride length.

Complete ruptures of the Achilles tendon were repaired in two hunting dogs of a 3-year-old, 20 kg and a 4-year-old, 14 kg with non weight bearing lameness. Both dogs were injured by wild animals and the skin defect was showed on the caudal surface of the right limb. Surgical repair involved the attachment of the ruptured tendon with a three-loop pulley method, using nonabsorbable suture materials. After surgical procedure, a bivalved cast was applied and maintained for 6 weeks. Exercise was restricted for 2 weeks more before gradually returned to normal. Gait and standing posture of dogs were returned to normal during the follow-up of 10 weeks.
