Purpose: The purpose of this study was to evaluate the impact of active vibration exercise on the neck pain, disability index, and muscle activity of patients with forward head posture. Methods: A total of 24 patients were randomly assigned to an experimental group or a control group (n=12 each). The experimental group performed active vibration exercise using a flexi-bar for 20 minutes a day, five times a week for four weeks. The study measured patient neck pain using a visual analog scale, neck pain related disability using the neck disability index, and muscle activity using electromyography. Results: The intragroup comparison showed significant differences in the visual analog scale score, neck disability index score and upper trapezius, lower trapezius and serratus anterior muscle activity values among patients in the experimental group. The intergroup comparison showed that differences in the visual analog scale score, neck disability index score and upper trapezius, lower trapezius and serratus anterior muscle activity values in the control group. Conclusion: This study showed that active vibration exercise was effective in improving the neck pain, disability index, and muscle activity of patients with forward head posture.
Objective: Core training is a key exercise for conditioning and fitness programs, injury prevention, and more. This study aimed to find out the effect of adding dynamic core training, which is frequently prescribed in clinical practice, on dynamic balance and muscle activity compared to conventional static core training. Design: An experimental study Methods: This study is an experimental pilot study of prospective parallel design. Six healthy young adults were allocated to static core training group (SCG; crunch and plank) and blended group (BG; crunch, plank, and dead bug exercise) for two weeks to perform core training. Dynamic balance and muscle activity (erector spinae, rectus abdominis) were measured for all participants before and after core training. Results: All six healthy young adults enrolled completed the study. No significant difference was found before and after 6 sessions of core training in each group (P>0.05). Likewise, no significant difference was found in the results of the difference comparison between groups (P>0.05). Conclusions: In conclusion, in this experimental study, no difference was found when dynamic core training was added. Although the results before and after core training did not show improvement in dynamic balance and muscle activity, a randomized controlled trial is needed considering the results of previous studies and the limitations of this experimental study.
Purpose : The purpose of this study was to investigate the effect of applying intensity on the muscle activity and muscle hardness of the upper trapezius muscle in adult males when TENS (transcutaneous electrical nerve stimulation) was applied. In addition, this study intends to prepare the scientific basic data of TENS for the purpose of relaxation based on the experimental results. Methods : Eighty-seven healthy adult males participated in the experiment, and they were randomly divided into an experimental group and a control group. All subjects in this study were healthy subjects without musculoskeletal or nervous system damage. All subjects were subjects who voluntarily consented to the purpose and method of the experiment. All subjects were provided with a load by typing for 20 minutes, and muscle activity and muscle hardness of the upper trapezius muscle were measured immediately. Afterwards, TENS was given to each groups for 15 minutes, and the experimental group received stimulation at the motor threshold level, and the control group received a placebo stimulation. After stimulation, muscle activity and muscle hardness of the upper trapezius muscle were measured in the same method. The measured data were compared between groups through an independent t-test and dependent t-test. The statistical significance level was set at .05. Results : The application of TENS statistically significantly decreased the muscle activity and muscle hardness of the trapezius muscle in the experimental group, and the results showed a significant difference from the control group. Conclusion : Application of TENS significantly decreased the muscle activity and muscle stiffness of the upper trapezius muscle. The application of TENS of applying intensity that induces muscle contraction may induce relaxation by reducing the muscle activity and muscle hardness of the trapezius muscle.
This study was designed to investigate the effects of exercise therapy on joint mobility, daily activity. pain and depression of patients with ankylosing spondylitis. 25 persons with the experimental group and 25 persons with the control group were conveniently sampled among out-patients diagnosed with ankylosing spondylitis at the rheumatism center of H University Medical Center. The control patients were matched to the experimental group and they were selected considering sex and age. The exercise therapy was developed by the author with the assistance of exercise specialists. The program includes muscle relaxation, flexibility, muscle strengths, breathing strengths and straight posture exercises. The 20-minute exercise therapy was carried out to the experimental group once a day for eight weeks from October. 1997 to February, 1998. Before and after the experiments, joint mobility, daily activity, pain and depression were measured respectively. Data were analyzed by $\chi$$^2$-test. t-test, paired t-test and unpaired t-test. The results were as follows : Joint mobility(cervical flexion, extension, shoulder flexion, abduction, hip abduction, knee flexion and fingertip to floor distance) and daily activity in the experimental group after the exercise were significantly increased than that in the control group. The pain and depression score in the experimental group after the exercise were significantly decreased than that in the control group. These findings may indicate that the exercise therapy is effective in increasing the joint mobility and daily activity, and also effective in decreasing pain and depression in patients with ankylosing spondylitis, Accordingly, the exercise therapy can be adopted as an effective nursing intervention for ankylosing spondylitis.
This study wa performed to investigate the effect of dired powder of chestnut and acorn on lipid metabolism, antioxidative capacity and antithrombotic effect in rats. Fifty-four male Sprague-Dawley rats weighing 199$\pm$17g were blocked into nine groups according to their body weight. Rats were raised with diets containing only flesh or flesh with inner skin of 5% and 10% dried nut powders for four weeks. Food intake, body weight gain, food efficiency ratio and organ weight were no different among the experimental groups. The plasma and liver lipid levels of all the nut diet groups were lover than those of the control group. The nut diets showed hypolipidenic effect in the plasma and liver. Plasma and liver thiobarbituric acid reactive substance (TBARS) concentrations were significantly decreased in all the nut diet groups. The plasma TBARS levels of the inner skin groups were significantly different from the control group dose-dependently. Superoxide dismutase(SOD) activity was significantly different among the experimental groups, and all the nut groups showed higher activity than the control group. There were significant differences in SOD activity between the chestnut and acorn groups and the chestnut groups showed higher erythrocyte SOD activity and the acorn groups showed higher liver SOD activity than the other groups. Whereas catalase and GSH-Px activities in the erythrocyte and liver of both nut groups showed a tendency to increase, they were not significantly different among the experimental groups. The bleeding time and whole blood clotting time tended to be extended by feeding both types of nut but they were not significantly different among the experimental groups. Production of TX $B_2$ and PG $F_{1{\alpha}}$ was no different among the experimental groups. These results suggest that chestnut and acorn diets have the effect of lowering plasma and liver lipid levels, inhibiting lipid peroxide formation and increasing antioxidative enzymes activity. Thus, it is plausible that chestnut and acorn could be recommended in the treatment and prevention of cardiovascular diseases.

β-Glucosidase production by the white rot fungus Flammulina velutipes CFK 3111 was evaluated using different carbon and nitrogen sources under submerged fermentation. Maximal extracellular enzyme production was 1.6 U/ml, corresponding to a culture grown in sucrose 40 g/land asparagine 10 g/l. High production yield was also obtained with glucose 10 g/land asparagine 4 g/l medium (0.5 U/ml). Parameters affecting the enzyme activity were studied using p-nitrophenyl-β-D-glucopyranoside as the substrate. Optimal activity was found at 50℃ and pHs 5.0 to 6.0. Under these conditions, β-glucosidase retained 25% of its initial activity after 12 h of incubation and exhibited a half-life of 5 h. The addition of MgCl2, urea, and ethanol enhanced the β-glucosidase activity up to 47%, whereas FeCl2, CuSO4, Cd(NO3)2, and cetyltrimethylammonium bromide inflicted a strong inhibitory effect. Glucose and cellobiose also showed an inhibitory effect on the β-glucosidase activity in a concentration-dependent manner. The enzyme had an estimated molecular mass of 75 kDa. To the best of our knowledge, F. velutipes CFK 3111 β-glucosidase production is amongst the highest reported to date, in a basidiomycetous fungus.
The purpose of this study was to examine effects of treadmill running training on superoxide product of spontaneously hypertensive rats. 20 males aged five week old rats were used for the experiments. They were randomly selected into experimental group (10 rats) and control group (10 rats) after being housed in laboratory for two weeks. The rats of experimental group performed treadmill exercise from 15 minutes for the first time to 35 minutes for the last one in order to familiar with experimental protocol ($VO_{2}max\;65{\sim}70%$, 0.9km/h, 5 times/week, 35 minutes/session). They began to perform treadmill running at the age of eight weeks for eight weeks. Superoxide production and NADPH oxidase activities were measured on the aortal from end of experiment. All statistical analyses and description methods were computed by SPSS Version 10.0. Differences in the values between experimental group and control group were calculated using t-tests. The results of this study were: there wewe no significant differences in superoxide production, NADPH oxidase-drivened superoxide activity, NADPH oxidase activity between two groups (p>.05). Spontaneously hypertensive rats of experimental group were characterized by higher superoxide production and lower NADPH oxidase-drivened superoxide activity and NADPH oxidase activity in comparison with the control group. One possible explanation of this finding was that NADPH oxidase activity of experimental group was lower than the control group. It can be concluded that treadmill running for eight weeks was associated positively with superoxide product of spontaneously hypertensive rats.
The effects of brisk walking & muscle strengthening exercise on pain, fatigue, physical function & disease activity were examined in 28 patients with rheumatoid arthritis. Research design was a quasi-experimental study of non-equivalent control group pretest-posttest design. 14 for the experimental group and 14 for the control group were selected from the out patients on rheumatoid arthritis clinic of Dong-A University Hospital. The experimental group underwent 16 weeks of brisk walking and muscle strengthening exercise using Thera-Band. Pain, fatigue, physical function & disease activity was measured before and after 16 weeks of exercise. At baseline test, Fatigue & physical function score between groups were significantly different. So differences with in experimental group(baseline versus follow up) were compared with differences within the control group by Mann-Whitney test. There were significant differences between groups in the difference score on pain (U=6.50 p<.001) and fatigue (U=26.5 p<.01). For the experimental group, the score on the pain & fatigue was significantly decreased but no changed for the control group. Also there was a significant differences between groups in the difference score of the physical function (U=22.5 p<.001). For the experimental group, the score of the physical function has been significantly in creased. However, for the control group, it has been no changed. But there were no significant differences between groups in the ESR (erythrocyte sedimentation rate) and the CRP (C-reactive protein)level. In summary, brisk walking & muscle strengthening exercise led to significant improvements in pain, fatigue, and physical function without exacerbating disease activity in patients with rheumatoid arthritis.
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.
