Purpose : This study focuses on the influence of bridge exercise combined with whole body vibration on muscle activity and balance. Methods : 30 stroke patients were recruited for subjects. The subjects were divided to bridge exercise combined stable surface (Group I), bridge exercise combined unstable surface (Group II), and bridge exercise combined bridge exercise (Group III), of which 10 subjects were randomly allocated. The subjects were given 30 minutes of neurologic physical therapy which included gait training and muscular strength training, and additionally given 30 minutes of bridge exercise combined stable surface, bridge exercise combined unstable surface, and bridge exercise combined whole body vibration for each group, five times a week, for 8 weeks. Their muscle activity and balance were analyzed before the intervention. After 8 weeks of the intervention, the mentioned parameters were measured once more for between-group analysis. Results : Comparative analysis of the muscle activity and balance between the groups showed statistically significant difference, and post-hoc analysis showed the Group III had greater changes in muscle activity and balance than Group Iand Group II. Conclusion : Such results revealed that bridge exercise combined with whole body vibration is effective in muscle activity and balance. Based on the current study, more effective program is to be proposed for elite athletes as well as stroke patients. Based on the current study, studies that incorporates various frequencies of vibration is required for development of effective whole body vibration exercise program.

The aim of this study was to investigate the effect of resistance training with and without whole-body vibration(WBV) on the biomechanical properties of the plantarflexor in the elderly women (>60 yrs., n=35). Thirty-five volunteers were randomly assigned to a resistance training with WBV group (RVT, n=14), a resistance training without WBV (RT, n=11), and a non-training control group (CON, n=10). The RVT and the RT groups participated in the training sessions three times a week for 8 weeks, followed by a 4-week detraining period. The CON group was instructed to refrain from any type of resistance training. To assess strength and activation of the plantarflexor muscles, maximum isometric ankle plantarflexion torque and muscle activation of the triceps surae muscles were measured using dynamometry, twitch interpolation technique and electromyography at four different ankle joint angles. Also, the lower extremity function was assessed by vertical jumping. The measurements were performed prior to, 2 and 8 weeks after the training and after a 4-week detraining period. Following the 8-week training sessions, an increase in the isometric plantarflexion strength was found to be greater for the RVT compared with the RT group (p<.05). Muscle inhibition was significantly decreased after training than before training only for the RVT (p<.05). Following the detraining period, a decrease in isometric plantarflexors strength and a increases in muscle inhibition were significantly less in the RVT compared with the RT group. In conclusion, the exercise with WBV is a feasible training modality for the elderly and seems to have a boosting effect when used with conventional resistance training.

Purpose : Chronic ankle instability can lead to problems in balance and gait due to weakness of the ankle muscles and decreased proprioceptive sensation. Balance training that stimulates proprioceptors is necessary to improve ankle stability. We aimed to compare the effects of unstable support balance exercises using whole body sonic vibration and an aero-step (TOGU) on proprioception and balance in individuals with unilateral functional ankle instability. Methods : Thirty-six participants with unilateral functional ankle instability were randomly recruited and divided into two groups (group 1 = sonic whole body vibration, group 2= TOGU). Individuals in each group participated in training for 5 weeks, 40 minutes per session, 5 times per week, and performed weight-bearing exercises in five postures on different unstable support surfaces. Proprioception was measured by digital inclinometer (Dualer IQ), and balance was measured by force platform (Biodex balance system). Results : Significant differences were observed in proprioception before and after intervention within both group (p<.05). Significant differences were also observed in the balance index before and after intervention within both groups (p<.05). Conclusion : As a result of this study, it is suggested that for individuals with ankle instability, unstable support surface training using a whole body sonic vibrator and TOGU can have a positive effects on proprioception and balance ability.

Objective: This study aimed to analyze the effects of consecutive whole body vibration through heel raise posture on the center of pressure and electromyography of anterior tibial muscle, lateral gastrocnemius and soleus muscles during single-leg stance. Method: The subjects of this study included 30 healthy males in their 20's, with the following inclusion criteria: no history of orthopaedic medical history, no participation in regular exercises, no history of whole body vibration exercise, and right leg being the dominant leg. The experimental procedure involved pretreatment measurement of eye open single-leg stance, application of whole body vibration for 30 seconds, post-treatment measurement (3 measurements in total). Static and dynamic movements have been measured over 2 separate experiments, with 72 hours gap between the experiments. Static movement involved maintaining single-leg heel raise posture for 30 seconds while applying whole body vibration, and dynamic movement involved heel raise (15 repetitions over 30 seconds) while applying whole body vibration. The strength of applied whole body vibration was 35 Hz frequency and 2~4 mm amplitude. Results: As the single-leg posture after static heel raise posture, mediolateral velocity of the center of pressure at post 2 and post 3 were significantly reduced compared to the pre-treatment measurement. In addition, the percentage for reference voluntary contraction in anterior tibial muscle and soleus and median frequency at anterior tibial muscle and lateral gastrocnemius muscle at post 3 were significantly decreased compared to the pre-treatment value. As the single-leg posture after dynamic heel raise posture, the mediolateral 95% edge frequency of the center of pressure and median frequency at anterior tibial muscle, lateral gastrocnemius muscle, and soleus muscle at post 3 were significantly reduced compared to the pre-treatment value. Conclusion: Acute whole body vibration via static and dynamic heel raise posture have positive effect on mediolateral posture control during single-leg stance.

PURPOSE: The purpose of this study was to provide fundamental clinical data to be used in therapeutic approach to patients with patellofemoral pain syndrome by administrating the squat exercise combined with whole body vibration exercise to them and investigating the effect of such exercise to leg muscle activity and muscle fatigue. METHODS: The patients with patellofemoral pain syndrome were randomly assigned to experimental group I (n = 9) where only squat exercise was administered and experimental group II (n = 9) where the squat exercise combined with whole body vibration exercise was provided. The intervention program was administered for two weeks, four days a week, one session a day, three set a session, and 20 reps a set. The pre- and post-test were performed to measure muscle activity and muscle fatigue of vastus medialis and vastus lateralis. RESULTS: The muscle activity significantly changed in both group (p < .05, p < .01, respectively) and the muscle fatigue showed significant change only in group I (p < .05). In addition, there was significant difference between groups in change of muscle fatigue of both muscles (p < .05) but not in change of muscle activity. CONCLUSION: The results showed that both exercise are effective in improving muscle activity, however, that the squat exercise combined with whole body vibration exercise is more effective in preventing muscle fatigue.

PURPOSE: This study aimed to provide supporting data for the clinical use of breathing exercise with a WBV stimulation as a sustained and safe intervention program, by examining the effect of breathing exercise with WBV stimulation on the pulmonary function, gait ability, and life quality in patients with severe chronic obstructive pulmonary disease (COPD), who have difficulty performing exercise. METHODS: For this study, after collecting the samples from 20 patients with severe COPD, they were placed randomly in an experimental group to perform breathing exercises with a WBV stimulation (n = 10) and a control group to perform breathing exercises only (n=10). Before the intervention, pulmonary function, six-minute gait distance, and health-related life quality were measured as pre-tests. After applying the intervention program to the patients for 30 minutes once a day, for four days a week, for six weeks, the post-test items were remeasured in the same way as the pre-tests, and the results were analyzed. RESULTS: In the within-group comparison, both the experimental and control groups showed significant differences in the forced expiratory volume in one second, six-minute gait distance, and health-related life quality (p < .01) (p < .05). In the intergroup comparison, there were significant differences in the forced expiratory volume in one second and the six-minute gait distance (p < .05). CONCLUSION: WBV stimulation was more effective for the patients by improving the muscular strength and muscular endurance through the reflexive contraction of muscles, and increasing the exercise tolerance. This result could serve as an alternative means to clinically improve the physical function of patients with severe COPD, who have difficulty performing breathing exercises in the future.

Purpose: The purpose of this study was to investigate the effects of whole-body vibration stimulation on proprioception and tactile in patients with spastic cerebral palsy. Methods: This study was conducted on 9 children diagnosed with spastic cerebral palsy. Of the single case study methods, the ABAB design was employed in this study. Out of a 12-week study period, three weeks were allocated to each of two baseline periods and two intervention periods. The exercise was performed twice a week for 30 minutes. A general trunk stabilization exercise was performed during the baseline period and a trunk stabilization exercise accompanied with whole-body vibration was performed during the intervention period. Evaluation was performed five times in total: before the experiment, after baseline 1, after intervention 1, after baseline 2, and after intervention 2. To determine the effect of the exercise method, a skin sensory evaluation tool (monofilament kit) and a trunk proprioception sensor (digital dual inclinometer) were used. To compare the effects of the exercises at baseline and after intervention, an analysis of variance on repeated measures (repeated ANOVA) was performed to analyze the data. Results: The results showed that there were statistically significant increases from baseline in the means of proprioception and tactile during the intervention period with whole-body vibration (p <.05). Conclusion: Whole-body vibration can be proposed as an effective intervention method for improving the proprioception and tactile in children with spastic cerebral palsy, and this exercise method is expected to be actively used in clinical practice.

Effect of whole body vibration exercise on intracerebral hemorrhage in rats. Intracerebral hemorrhage is one of the most devastating types of stroke. This disease is known to cause severe neurological damage and also has a very high mortality rate. In the present study, the effects of whole body vibration exercise on memory capability and apoptotic neuronal cell death in the hippocampal CA1 region following intracerebral hemorrhage in rats were investigated. Intracerebral hemorrhage was induced by injection of collagenase into the hippocampal CA1 region using a stereotaxic instrument. The rats were divided into 5 groups: the sham-operation group, the hemorrhage-induction group, the hemorrhage-induction and 8 Hz vibration exercise group, the hemorrhage-induction and 16 Hz vibration exercise group, and the hemorrhage-induction and 24 Hz vibration exercise group. The animals in the whole body vibration exercise groups received whole body vibration at 8 Hz, 16 Hz, and 24 Hz, respectively for 30 min once a day during 14 consecutive days. In the present results, the apoptotic neuronal cell death in the hippocampal CA1 region was significantly increased following induction of intracerebral hemorrhage, resulting in memory impairment. Whole body vibration exercise suppressed hemorrhage-induced apoptosis in the hippocampal CA1 region. This suppressive effect of whole body vibration exercise also alleviated hemorrhage-induced memory impairment. Here in this study, we have shown that whole body vibration exercise inhibited intracerebral hemorrhage-induced apoptotic neuronal cell death and thus facilitated recovery of brain function following intracerebral hemorrhage.

Purpose : The purpose of this study was to analyze the therapeutic effect of plasmapheresis in various pediatric diseases. Methods : Therapeutic plasmapheresis was performed by COBE Spectra centrifugation. Nine cases were included in this study. The number an[;. method of plasmapheresis, together with the progress and prognosis of each case were retrospectively reviewed. Results : The patients' ages ranged from 26 mont]Is to 16 years of age, and the mean age was 9.9 years. There were S males and 4 females. The underlying diseases requiring plasmapheresis included 2 cases of hemolytic uremic svndrome(HUS), 1 case of lupus nephritis, 2 cases of rapidly Progressive glomerulonephritis(RPGN), 1 case of focal segmental glomorulosclerosis(FSGS), 1 case of systemic vasculitis after pulmonary hemorrhage, 1 case of acute renal failure associated with pulmonary hemoIThage, and 1 case of acute rejection after renal transplantation. The average number of plasmapheresis performed was 6.2 times with a range of 3 to 13 times. The patients with HUS, lupus nephritis, ANCA positive systemic vasculitis induced by pulmonary hemorrhage and ARF-associated pulmonary hemorrhage showed a good response to therapeutic plasmapheresis, but the patients with RPGN, refractory FSGS, and acute rejection after renal transplantation were not responsive to treatment. The most common side effect was hypocalcemia which was rarely symptomatic. Vital signs were not compromised. Conclusion : Although it is presumptuous to generalize the therapeutic effects of plasma pheresis in different diseases due to the small number of study subjects, this study shows that plasmapheresis may be an effective therapeutic modality in various pediatrics diseases and should be considered as a therapeutic option.
