PURPOSE: This study intended to verify whether there was actual correlation between weight-bearing asymmetry and a limitation in hip joint rotation range in patients with low back pain. METHODS: Thirty five low back pain patients voluntarily participated this study. For each participant, hip joint medial rotation symmetry rate and the weight-bearing symmetry rate were calculated. The correlation between the two variables was investigated. RESULTS: A decrease in the left hip joint medial rotation range of motion (ROM) was observed more often than a reduction in the right hip joint medial rotation ROM. However, similar number between right and left side was observed in ground reaction force more weighted. The coefficient between the passive hip joint medial rotation symmetry rate and the weight loading symmetry ratio was -0.19 (p < 0.05). CONCLUSION: The present study demonstrated a weak correlation between the hip joint medial rotation ROM and the weight distribution of both feet. Such result suggests that careful evaluation by separating each element is needed in treating patients with low back pain. Future research should take into account asymmetric alignment and abnormal movement in different joints of the body as well as asymmetry in the bilateral hip joint rotation and the unilateral weight supporting posture.

Purpose : This study was conducted to investigate the effect of positive active pressure technique and active breathing technique on lung function in healthy adults. Methods : In this study, the passive lung expansion technique and active respiration enhancement technique using an air mask bag unit were conducted in 30 normal adults to observe changes in pulmonary function with forced vital capacity (FVC), Forced expiratory volume at one second (FEV1). In order to observe the change in the level of respiratory function, we would like to investigate the peak expiratory flow (PEF) and the forced expiratory flow (FEF 25-75 %). Results : As a result of this study, there was no significant difference in comparison between the passive lung expansion technique and the active breathing enhancement technique (p>.05). The passive lung expansion technique effectively increased the effortful expiratory volume and the median expiratory flow rate of 1 second (p<.05). And the passive lung expansion technique effectively increased the effortless lung capacity and the maximum expiration flow rate (p<.05). Conclusion : The passive lung expansion technique effectively increases the range of motion of the lungs and chest cages, intrathoracic pressure, and elasticity of the lungs, and the active breathing technique increases the muscle functions such as the diaphragm and the biceps muscles. It is expected that it will be able to selectively improve the respiratory function of patients with respiratory diseases or functional limitations as it is found to be effective.

We measured, with manual goniometer, the active and passive arc of motion of the shoulder in 31 healthy male subjects who were right-hand dominant and who ranged in age from twenty to thirty-one years. Among ten directions through the four motion plane, the range of motion on the dominant side were significantly smaller than those on the non-dominant side in the motion of six directions. We also measured the motion fraction of the glenohumeral and scapulothoracic movement using fluoroscope in 30-degree intervals of arm elevation in the scapular plane. The ratio of glenohumeral to scapulothoracic movement(θGH/θST) was 1.6 for the full range of motion in scapular plane. At the lower angles of abduction, scapulothoracic movement was slight compared with glenohumeral movement. The motion fraction of scapulothoracic joint was increased from 60-degree to 150 degree of arm angle especially between 120 to 150 degree. During arm elevation, scapula was also extended from 42 degrees to 20 degrees tilting as well as internal rotation. The measuring technique of glenohumeral to scapulothoracic movement(θGH/θST) with fluoroscopy could be applied to the simple radiographic measurement at the out-patient clinic in order to identify the pathology and recovery of shoulder motion after treatment.

This study aimed to determine the usefulness of classifying patients with neck pain on the basis of the results of passive scapular elevation test. We classified 21 patients with neck pain into positive (n=12) and negative (n=9) groups on the basis of passive scapular elevation test; the 2 groups then equally performed scapular stabilization exercise program for 30 min, 3 times a week, for 4 weeks. Visual analogue scale (VAS), neck disability index (NDI), and range of motion (ROM) were recorded both before and after the intervention for both groups. Paired t-test was used to determine that there were significant changes between before and after the intervention, and independent t-test was used for analyzing changes between two groups of dependent variables. After 4 weeks of training, we observed significant decrease in pain and disability (p<.05) and a significant increase in rotation, flexion, extension, and side-bending ROM (p<.05) in both groups. Further, between pre- and post-intervention evaluations, we observed a significant decrease in pain and disability and a significant increase in rotation and flexion ROM in the positive group than in the negative group (p<.05). These results indicate that passive scapular elevation test may be used to identify mechanical disorders of the cervicoscapular muscle in patients with neck pain. Therefore, we recommend the use of passive scapular elevation test to determine appropriate treatment intervention when treating patients with neck pain.

Objective: The purpose of this study was to evaluate the effect of passive-acute temperature therapy of the femoral muscle and dynamic warm-up on the countermovement jump performance. Method: Twenty male track and field athletes from national team underwent three treatments applied on the femoral muscles; cold temperature treatment, thermal treatment and dynamic warm-up. The variables extracted at 2 time points (pre-measurement and post measurement) were the temperature of the left and right femoral muscle, displacement & velocity of centre of mass, peak power out, range of motion and moment & power of the knee joint. Results: There was a statistically significant difference in the temperature of the femoral muscle according to measurement time which was high in the order of thermal treatment, dynamic treatment and cold treatment. The jump height was the highest in the dynamic warm-up with no statistically significant difference for the range of motion of the knee joint. The peak power out at dynamic warm-up and the power of the knee joint were statistically significant according to the treatment and measurement time. Conclusion: Local cold and thermal treatment of femoral muscles at ambient temperature did not improve jump performance, while dynamic warm-up was considered to be effective for maintaining the performance of the activities that require strong muscular power.

The purpose of this study was to determine the outcome of distal femoral osteotomy for distal femoral varus and medial patellar luxation (MPL) grade 4 in small-breed dogs. Radiographs and medical records were reviewed to collect data and plan the surgery in small-breed dogs with MPL grade 4. Computed tomography (CT) imaging was also performed in cases of severe bone deformities. Signalment, weight, medial patellar luxation and lameness grade, radiographic bone union, complications, pre- and postoperative femoral varus angle, passive range of motion, static weight bearing distribution and visual analogue scale scores were recorded. Thirteen corrective distal femoral osteotomies were performed with ancillary and additional procedures in 9 dogs; 4 dogs had staged bilateral procedures; and four stifles were suspected to have partial or complete rupture of the cranial cruciate ligament. One stifle underwent patellar groove replacement. The mean ± SD pre- and postoperative femoral varus angles were 109.15°± 3.71° and 96.30°± 2.97°, respectively. Significant improvements in passive range of motion, thigh circumference and visual analogue scale (VAS) scores were observed. There was no reluxation of the patella. This study suggests that distal femoral osteotomy with traditional and additional procedures provided satisfactory outcomes in patient healing and functional recovery in small-breed dogs with excessive femoral varus angles.

Objective: Musculoskeletal neck pain have many symptoms which include decreased range of motion (ROM) and muscle strength, and increased pain. However, the management methods are controversial. The purpose of this study was to examine the effects of three interventions on ROM, strength, and pressure pain threshold (PPT) with musculoskeletal neck pain. Design: Pretest-posttest design. Methods: Thirty subjects participated in this experiment. They were randomly assigned to thefollowing groups: passive stretching (PS) group (n=10), massage (MASS) group (n=10), and muscle energy technique (MET) group (n=10). The treatment were applied bilaterally on the upper trapezius. The PS was applied 3 times for 30 seconds each time. The MASS was applied using two different techniques for 2 minutes per technique. For MET, the subjects performed 2 sets of 3 repetitions of isometric resistance exercise that was maintained for 10 seconds, followed by 10 seconds of rest. ROM, strength, and PPT parameters were measured after intervention. Results: In the MASS group, there was a significant improvement in all outcomes except for muscle strength (p<0.05). In the MET group, ROM and strength significantly improved compared to the pre-treatment results (p<0.05). As result of measuring the amount of change in each group, there was a significant difference in ROM (flexion) in the PS group compared with the MASS and MET group, a significant difference in strength in the MET group compared with the PS and MASS groups, and a significant difference in PPT in the MASS groups compared with the PS and MET groups (p<0.05). Conclusions: This study showed that PS, MASS, and MET are effective methods for improving ROM, strength, and PPT for musculoskeletal neck pain. Therefore, various therapeutic interventions for improving ROM, strength, and pain are suggested.

The purpose of this study is to report the effect of oriental medical treatments with exercise therapy on the frail elderly patient with gait disturbance and cognitive decline. The frail elderly patient with gait disturbance and cognitive decline was treated by oriental medical treatments combined with exercise therapy during 3 months. The improvement of clinical symptom was evaluated by Manual Muscle Test (MMT), Passive Range Of Motion (PROM), Mini Mental State Examination-Korea (MMSE-K). After 3 months, all of both lower extremity Manual Muscle Test (MMT) improved to Grade 4. Both knee extension Passive Range Of Motion (PROM) and Mini Mental State Examination-Korea (MMSE-K) also increased from -30/-30 to 0/-5, from 7 to 25 respectively. It could be suggested that oriental medical treatments with exercise therapy were effective on the frail elderly patient with gait disturbance and cognitive decline. And further research is encouraged to confirm the effectiveness of this treatment with a larger number of patients.
