Purpose: The purpose of this study was to investigate the effect of regularly strength exercise of spine in teenagers with tutor. Method: Study subjects were 24 middle school students. They were arranged to 2 groups(n=12, respectively). Then experimental group did regularly strength exercise of spine as the handout maneuver during 50min/day and 1day/week in 8 weeks with tutor, but control group did regularly exercise of spine as same maneuver without tutor. For muscle strength of both extensor and flexor of lumbar, the balancing ability and weight distribution index were measured before and after the intervention. Results: For muscle strength of both extensor and flexor of lumbar, there was not significant differences after the intervention, but both flexor and extensor increase mean value of muscle strength than control group. For balancing ability and weight distribution index, there were not significant difference after intervention(p>.05), but experimental group show a tendency to decrease in a few position than control group. Conclusion: When teenagers regularly exercise for spine strengthening for a long time with tutor, it may be increased muscle strength of lumbar and trunk balance.

The purpose of this study was to find the effects of the lumbar stabilizing exercise on the isometric lumbar extension strength and the range of motion of lumbar extension. 16 healthy subjects were recruited (9 males, 7 females, mean age 25${\pm}$3.2). They performed 5 types of exercises 5 times per week for 4 weeks. We evaluated isometric trunk extension strength (0, 12, 24, 36, 48, 60, $72^{\circ}$) by MedX(Ocala, FL) and measured range of motion of lumbar extension. All measurements were measured at pre-exercise and 4 weeks post-exercise. The results of this study were summarized as follows; After 4 weeks of exercise, isometric lumbar extension strength was generally increased but there were only significant differences at $12^{\circ},\;24^{\circ},\;48^{\circ}$. The range of motion of lumbar extension was increased (p<.05). The isometric lumbar extension strength correlated with the range of motion of lumbar extension. In conclusion, our results have shown that lumbar stabilizing exercise influenced both lumbar extension strength and range of motion of lumbar extension.

Purpose : The purpose of this study was to evaluate the effect of 6 weeks of sling exercises on female patients 20 years of age with low back pain according to flexibility, balance, muscle strength and pelvic tilt. Method : The 20 female patients who complained of back pain were divided into two groups. The experimental group exercised for 40 minutes, 3 times a week for 6 weeks. The control group did not. Both groups were measure for flexibility, balance, muscular strength, and pelvic tilt angle. Result : Curvature of the experimental flexibility, stretch, balance, muscle strength of the trunk forward, backward, left rotation, right rotation for the sling exercise group had significant differences. However, pelvic tilt did not show a significant difference. Control of the stretch of the flexibility, balance, and muscle strength of the trunk posterior showed significant differences for the sling exercise group. Conclusion : Although significant differences were found in flexibility, balance, muscular strength, there was no difference in pelvic tilt. When selecting subjects, we believe patients with regular patterns of pain will be more effective for statistical analysis of the changes in pelvic tilt.

Purpose : The purpose of this study is to investigate the effect of strengthening program for improving the muscle strength and body function in rehabilitation of patients with stroke Methods : We found the 15 precedent studies at online portal site of "Korea education and Research information service" and found 5 precedent studies at "Pubmed". We analyzed and describe the total 19 studies involving national and international research. Results : The strengthening exercise was adapted to lower extremities and trunk muscle of participants and the isokinetic (concentric and eccentric) exercise was most of exercise type and then manual isometric exercise, functional activities, progressive task oriented resistance exercise, PNF pattern exercise was following. The studies reported that the strengthening program increased target muscle strength and improved balance capacity and walking function for the participants positively. Conclusion : Conclusionally the several strengthening program can be the intervention to increase the muscle strength without increasing spasticity for patients with stroke. We think that the strengthening of lower extremities an improve balance capacity and walking ability and it can use the intervention to change the quality of life in patients with stroke. More than 3weeks strength program might be effectiveness, in case of acute patients with stroke, the improving of muscle strength is available but need to study for improving balance and walking capacity more in the future.

Purpose : The purpose of this study was to assess the effects of the trunk muscle activity on bridging exercise according to the knee joint angle. Methods : Twenty-five healthy adults volunteered to participate in this study. Subjects were required to complete following four bridging exercises; knee joint flexion $120^{\circ}$, $90^{\circ}$, $60^{\circ}$, $45^{\circ}$. Surface electromyography from selected trunk muscles was normalized to maximum voluntary isometric contraction. Muscle activity was measured by QEMG-4 system(LXM 3204, Laxtha Korea). A repeated measures of one-way ANOVA with post-hoc Bonferroni's correction was used to determine the influence of bridging exercise on muscle activity for each muscle and descriptive statistics was used to determine local/global muscle ratio. Results : The internal oblique of bridging exercises $120^{\circ}$, $90^{\circ}$ showed significantly(p<.05). The erctor spinae of all bridging exercises showed significant excepted between $60^{\circ}$ and $45^{\circ}$(p<.05). Median of internal oblique/rectus abdominis ratio of $120^{\circ}$ was 4.41, $90^{\circ}$ was 3.94, $60^{\circ}$ was 3.58, $45^{\circ}$ was 3.39. Median of internal oblique/external oblique ratio of $120^{\circ}$ was 2.66, $90^{\circ}$ was 2.43, $60^{\circ}$ was 2.87, $45^{\circ}$ was 2.64. Conclusion : Angular motion decreasing with knee joint flexion made erector spinae activation increase. on the other hand, as decreasing abdomen muscle activation, the more performing motor learning is required for abdomen muscle strength and co-contraction for the trunk stabilization.

Purpose : This study aims to present a rehabilitation exercise and physical education program (REPEP) for local community stroke patients by examining an exercise program provided from traditional physical therapeutic perspectives. Methods : The subjects were 40 stroke patients residing in a local community and managed by a public health center (the group-exercise group: 20, the individual-exercise group: 20). In the case of the group-exercise group (GEG), the subjects were divided into small groups composed of five members each to participate in the program. The individual-exercise group (IEG) took part in the program individually. The subjects received a REPEP that included a warm-up exercise, an elastic band exercise, a leg exercise, a balance and gait exercise, an arm and trunk exercise, and a cool-down exercise twice per week for 20 weeks. They had their gait function, balance index, and muscle strength in the bilateral knee joints tested before and after the experiment. Results : Compared to before the experiment, both groups' gait function, balance index, and muscle strength in the knee joints increased after the experiment. After the experiment, the GEG experienced more improvement in their gait function, balance index, and muscle strength in the bilateral knee joints, excluding their gait velocity and $300^{\circ}/sec$ flexion and extension, than the IEG (p<.05). Conclusion : An exercise program provided from the traditional physical therapeutic perspectives may be applied to stroke patients as their REPEP. In addition, a REPEP was more effective in improving their gait function, balance index, and muscle strength in the knee joints when the subjects formed a group and took part in the program than when they partook in it individually.

The purpose of this study was to analyze the effect of different types of rehabilitation training program on the kinetic and kinematic parameters during sit-to-stand movement(STS) in chronic stroke patients. Two groups of hemiparetic patients, experimental and control, participated in the study. The experimental group participated in a 10-week training program (three sessions/wk, $1{\sim}1.5\;hr/session$) consisting of a warm-up, aerobic exercises, lower extremity strengthening. and a cool-down. The control group participated in an aerobic exercise. Three dimensional kinematic analysis and force platform; were used to analyze the duration of STS, lower extremity angle, and weight bearing ability. The experimental group which had more strength of lower extremity displayed decrease in duration of STS. However, the control group showed increases in duration during sit-to-stand movement. The control group flexed their trunk more than the group did Therefore, it took more time to extend their trunk during STS. The duration in sit-to-stand was affected by the strength of lower extremity and the angle of trunk movement. The angles of ankle and knee joint had an influenced on duration of STS. The post experimental group performed with their feet near the front leg of the chair during sit-to-stand, therefore the duration was decreased. The repetitive sit-to-stand movements as a resistance exercise was effective to hemiparetic patients in learning mechanism of sit-to-stand. The control group showed decreased differences in the vertical ground reaction forces between paretic and non-paretic limbs. Their training program included strengthening exercise that may help improving weight bearing ability. The control group showed increases in the center of pressure in the anteroposterior and mediolateral displacement. This means that the stability of movement was low in the control group. Their training program which combined aerobic and strengthening exercises that are more effective to improve the stability of movement.
