Purpose: The purpose of this study was to investigate the effects of passive upper arm exercise on range of motion, muscle strength, and muscle spasticity in hemiplegic patients with cerebral vascular disease. Methods: A quasi-experimental design with nonequivalent control group was utilized. According to inclusion criteria, 25 patients were assigned to the control group with routine care, followed by 25 to the intervention group with passive exercise for 30 minutes per session, twice a day for 2 weeks. Eighteen patients in the intervention group and 17 in the control group completed the posttest measurement, including range of motion for upper arm joints, manual muscle test, and Modified Ashworth Scale for muscle spasticity. Results: The intervention group had a significantly improved range of motion in the shoulder and wrist joints. No interaction effect was found for the elbow joint. No significant differences were found in muscle strength or muscle spasticity between the groups. Conclusion: Results of the study indicate that passive exercise safely applied for two weeks improves range of motion in joints of the upper arm in these patients. Further study with long-term follow-up is needed to verify the role of passive exercise in preventing muscle spasticity in this population.

The deep ocean engineering basin (DOEB) of the Korea Research Institute of Ship and Ocean Engineering (KRISO) is equipped with an extreme-environment reproduction facility that can analyze the motion characteristics of offshore structures and ships. In recent years, there have been requirements for a wide range of six-degree-of-freedom (6-DOF) motion measurements for performing maneuvering tests and free-running tests of target objects (offshore structures or ships). This study introduces the process of developing a wide-area motion measurement technology by incorporating the auto-tracking technology of the towing carriage system to overcome the existing 6-DOF motion measurement limitation. To realize a wide range of motion measurements, the automatic tracking control system of the towing carriage in the DOEB was designed as a speed control method. To verify the control performance, the characteristics of the towing carriage according to the variation in control gain were analyzed. Finally, a wide range of motions was tested using a model test object (a remotely operated vehicle (ROV)), and the wide-area motion measurement technology was implemented using an automatic tracking control system for a towing carriage.

Purpose: The purpose of this study is to acknowledge the effects that have the strength exercise done only on the neck extensor, only on the thoracic extensor, and both the neck and the thoracic extensor on forward head posture(FHP) and cervical range of motion. Also is to discover which of the exercise is the most effective. Method: This experiment will be done by selecting 40 people who have 16cm or more FHP and they will be divided into four groups: three experimental groups and a control group. The first experimental group will do only the neck extensor strength exercise(NESE). The second experimental group will do only the thoracic extensorstrength exercise(TESE) and the third experimental group will do both the NESE and the TESE. The experimental groups will make a day three times each ten sets of extensor isometric strength exercise but the time will be increased from 4 to 6 and8 seconds until it will be done the ten sets. Then after four weeks, they will be compared which had the best results for the FHP and the cervical range of motion. Result: After the experiment, it was compared the experimental groups with the control group. Every experimental group had an improvement on their FHP and cervical range of motion. However, the only NESE and the only TESE did not have a significantly difference(p>.05). Only the group who did both the NESE and the TESE had a sign ificantly improvement compared to the control group. Conclusion: 1. The only NESE and the only TESE seem that had a positive effect on FHP and cervical range of motion. However, it cannot be conclude that it is effective. 2. When both the NESE and the TESE are done, it is showed statistically a significant difference(p<.05) on FHP and cervical range of motion. The refore, it would be note worthy if this exercise is used to improve the FHP and the cervical range of motion.

PURPOSE: The aim of this study was to evaluate the concurrent validity and clinical usefulness of the universal plastic goniometer to measure the range of motion of the internal and external rotation of the hip joint using the three dimensional motion analysis which can analyze the joints and segment movements in the most objective and quantitative method. METHODS: Clinical and kinematic data were collected from thirty individuals using a universal plastic goniometer and a ten camera motion analysis system. Passive hip rotation range was obtained three trials for left and right hip joints using two measure methods simultaneously. RESULTS: There were significant differences between all matching measures of the two measures of internal and external rotation of the hip joint (p<.05). The relationship between the two tests for all measurements of the internal and external rotation of the hip was statistically significant with correlation coefficient form r=.87 to .96. (p<.01). CONCLUSION: Clinical measurement of the internal and external rotation of the hip using a universal plastic goniometer is effective to assess the hip condition. However, application of universal plastic goniometer requires careful attention in more accurate evaluation and research verification of the internal and external rotation of hip joint.
