Purpose: This study was done to assess the effect of changes in forward head posture (FHP), neck mobility and headache clinical parameters on episodic tension-type headache (ETTH) and chronic tension-type headache (CTTH) who did craniocervial exercises. Methods: Twelve CTTH subjects and twelve ETTH subjects were studied. Side-view pictures of subjects were taken in both sitting and standing positions, in order to assess FHP by measuring the craniovertebral angle. Cervical range of motion (CROM) was employed to measure cervical mobility. A headache diary was kept to assess headache intensity, frequency, and duration. All subjects did three types of craniocervical exercise over 8 weeks. Measurements were done at pre-treatment, and at 4 and 8 weeks post-treatment. Results: Forward head posture and headache-related clinical parameters showed a significant improvement after craniocervical exercise (p<0.05). Flexion/extension and left/right rotation of CROM was significantly increased after the intervention (p<0.05), whereas changes in left/right bending did not reach statistical significance. Conclusion: This study indicates that craniocervical exercise may be effective in the management of tension-type headache.

Objective : The purpose of this study was to investigate the effects of landing height and knee joint muscle fatigue on the movement of the lower extremity during cutting after landing. Method : Subjects included 29 adults (age: $20.83{\pm}1.56years$, height: $172.42{\pm}9.51cm$, weight: $65.07{\pm}10.18kg$). The subjects were asked to stand on their dominant lower limb on jump stands that were 30 and 40 cm in height and jump from each stand to land with the dominant lower limb on a force plate making a side step cutting move at a $45^{\circ}$ angle with the non-dominant lower limb. The fatigue level at 30% of the knee extension peak torque using an isokinetic dynamometer. Results : The results showed that the difference of landing height increased maximum range of motion and angular velocity of hip, knee, and ankle joints in the sagittal plane, and in the angular velocity of motion of the hip joint in the sagittal plane. The maximum range of motion of the knee joint in the sagittal plane and the frontal plane decreased on landing from both heights after the fatigue exercise. The angular velocity of the hip joint in the sagittal plane, and the maximum range of motion of the hip joint in the transverse plane decreased for both landing heights after the fatigue exercise. The angular velocity of the hip joint in the frontal plane decreased for the 30 cm landing height after the fatigue exercise. On the other hand, the angular velocity and maximum range of motion of the ankle joint in the sagittal plane for both landing heights, and the angular velocity and maximum range of motion of the ankle joint in the frontal plane increased on landing from the 40 cm height after the fatigue exercise. Conclusion : Different landing heights of 30 and 40 cm and 30% fatigue of peak torque of knee extensor found a forefoot and stiff landing strategy, when cutting after landing. These results might be due to decline in the shock absorption capability of the knee joint and the movement capability related to cutting while increasing the contribution of the ankle joint, which may cause increased ankle joint injuries.

Purpose : The purpose of this study was to identify the effect of lumbar stabilization exercise (LSE) and isometric lumbar strengthening exercise (ILSE) on lumbar strength and lumbar extension range in healthy young adults. Method : Ten healthy young adults (six males and four females) volunteered to carry out the LSE and ILSE program for two weeks. The subjects were randomly allocated to two groups: the LSE group (n=5) and the LSE plus ILSE group (n=5). The LSE consisted of 20 minutes of exercise related to lumbar stabilization, and the ILSE was composed of five minutes of isometric stabilization exercise with a specific device. Each group exercised three times per week for two weeks. Assessment tools were made using the subjects' isometric lumbar strength and lumbar extension range before and after the interventions. Results : Statistical analysis revealed significant differences in isometric lumbar strength and the lumbar extension range between before and after the interventions in each group (p<.05). Also, the lumbar extension range improved significantly in the LSE plus ILSE group compared to the LSE group; however, there was no statistically significant difference in the two groups' isometric lumbar strength (p>.05). Conclusion : The findings suggest that ILSE might be feasible in clinical settings by offering benefits for lumbar function. Future studies will be continued.

The subjects were 31 women aged between 40 and 60 who visited the out-patient department at Kang Nam St. Mary's Hospital for follow-up care. and were not under the treatment of intravenous cancer chemotherapy or radiation therapy. and had no complications. Twelve of them were assigned to the control group. while nineteen subjects to the experimental group. The aquatic exercise program was developed by the author with the assistance of exercise specialists. The program includes warming uP. aerobic and cooling down exercises in water. The aquatic exercise program for the experimental group was carried out 3 times a week with 60 minutes in each time for 8 weeks from September 20th to November 15th. 1995 in a regular swimming pool in Seoul. Changes in the range of motion of the shoulder joint. muscle strength. physical symptom. quality of life. and stress were examined after the completion of treatment. The data were collected through isokinetic muscle strength evaluation and questionnaire survey before and after the treatment. Paired and unpaired t-test were adopted to analyze the data. The results were as follows ; 1. The increment in the range of motion of the shoulder joint in the experimental group after the exercise was significantly greater than those in the control group. 2. The peak torque of shoulder girdle muscles increased significantly after the exercise in the experimental group only. 3. The physical symptom score decreased significantly after the exercise in the experimental group only. 4. The experimental group revealed significantly higher level of quality of life and lower level of stress after the exercise compared with those before the exercise. whereas the control group showed no significant changes in those levels. These findings may indicate that the aquatic exercise program is effective in increasing the range of motion of the shoulder joint and muscle strength and quality of life. and also effective in decreasing physical symptoms. and the level of stress in postmastectomy patients. Accordingly. the acquatic exercise program' can be adopted as an effective nursing intervention for postmastectomy rehabilitation.

Purpose: This study was conducted to determine the effects of motion taping on muscle activity and the WOMAC in a rehabilitation exercise program for elderly women with knee joint osteoarthritis. Methods: The subjects were 28 elderly women aged over 65 years with knee joint osteoarthritis. The subjects were divided into two groups: one experimental and one control group. During the study period, a total of 26 patients completed the experiment, with one drop each from the experimental group and control group. The experimental group applied motion taping and conducted a rehabilitation exercise program. The control group experienced a rehabilitation exercise program without motion taping. The rehabilitation exercise program consisted of warm-up exercises, maximum isometric exercises, the range of motion of the joints, and leg stretching exercises. The intervention was conducted three times a week for six weeks. To investigate the effects of the intervention, muscle activity and the WOMAC were measured. The WOMAC is a tool that can be used to evaluate the pain, stiffness, and physical function of osteoarthritis patients; it has 29 items in three areas. Results: The change in muscle activity according to the intervention showed a statistically significant increase in both the experimental group and control group. The WOMAC also showed statistically significant changes in terms of pain, stiffness, and physical function in both the experimental and control groups. The experimental group showed a greater functional improvement than the control group. Conclusion: For older women with osteoarthritis of the knee, a rehabilitation exercise program is a good intervention. When motion-taping is applied, it is considered to be an intervention program that can be expected to have a better effect on knee joint osteoarthritis.

Background: The purpose of this study is to examine the effect of resistance exercise on static and dynamic proprioception by applying elastic bands to the knee flexor, which can be performed earlier than proprioception, a weight bearing pattern. Proprioceptive training may be applied to the early period of recuperation training along with resistance exercise to prevent damage to the knees and the joints in the lower body, as well as the reoccurrence of injury, which is expected to improve the effect of static and dynamic proprioceptive training. Methods: The subjects of this study were 32 men and women in their 20s who volunteered to participate in the experiment which was carried out over the course of 6 weeks from March 14 to April 24 at K Hospital located in Yongin City. They were tested in two groups: the elastic band resistance exercise group (RE: Resistance Excercise Group, n＝17) and the joint motion range exercise group(ROM: Range of Motion Group, n＝15). In this experiment, static and dynamic proprioceptive tests were given to both groups before and after the test. In this study, SPSS Win ver.12.0 was utilized to perform a T-test on the independent samples in order to validate the identical features of subjects in the RE and ROM Group and substantiate the significance as to the difference between both groups before and after the test. Also, a paired T-test was conducted to compare the static and dynamic proprioception of both groups before and after the test. The statistical significance levels were ${\alpha}$＝.05. Results: 1.The static proprioception in both groups, RE and ROM, increased in a statistically significant way after the test(p<.05). 2.The static propriocetion of the RE group increased in a statistically significant way after the test(p<.05). However, the increase of the static proprioception in the ROM group was not statistically significant. 3.Static and dynamic proprioception of the RE group increased significantly more than that of the ROM group after the test(p<.05). Conclusion: The resistance exercise using elastic bands improved the static and dynamic proprioception more than the joint motion range exercise did, reducing the risk of injury by enhancing the location sense of the joints and the sense of motion and shortening the period of recovery from injury. The outcome of the experiment may provide basic data for developing an effective way to reduce the risk of injury among ordinary people and athletes.

This paper presents a rehabilitation exercise system which utilizes a 6 DOF robot as a motion generator. This system was proposed for a stroke patient or a patient who has hemiplegia. A master-slave system was designed to exercise either paralysis or abnormal limb by using normal limb motion. The study on the human body was applied to calculate the motion range of elbows and shoulders. In addition, a force-torque sensor was applied to the slave robot to estimate the rehabilitation extent of the patient. Therefore, the stability of the rehabilitation robot could be improved. By using the rehabilitation robot. the patients could exercise by themselves without assistance. In conclusion, the proposed system was verified by computer simulations and system experiment.
