Purpose: The aim of this study was to review the literature to determine whether intensive pelvic floor muscle training during pregnancy and after delivery could prevent urinary and fecal incontinence. Methods: Randomized controlled trials (RCT) of low-risk obstetric populations who had done Kegel exercise during pregnancy and after delivery met the inclusion criteria. Articles published between 1966 and 2012 from periodicals indexed in Ovid Medline, Embase, Scopus, KoreaMed, NDSL and other databases were selected, using the following keywords: 'Kegel, pelvic floor exercise'. The Cochrane's Risk of Bias was applied to assess the internal validity of the RCT. Fourteen selected studies were analyzed by meta-analysis using RevMan 5.1. Results: Fourteen RCTs with high methodological quality, involving 6,454 women were included. They indicated that Kegel exercise significantly reduced the development of urinary and fecal incontinence from pregnancy to postpartum. Also, there was low clinical heterogeneity. Conclusion: There is some evidence that for antenatal and postnatal women, Kegel exercise can prevent urinary and fecal incontinence. Therefore, a priority task is to develop standardized Kegel exercise programs for Korean pregnant and postpartum women and make efficient use of these programs.

The purpose of this study was to investigate the effects of vibration exercise using surface electromyography. Seven male collegiate wrestlers were participated in this study. Each subject stood on the platform and the vibration was induced for 1min. WEMG8 EMG system was used to record muscle activity from Vastus lateralis, Biceps Femoris, Tibialis Anterior, and Gastrocnemius. The EMG data were sampled for 30 sec. during non-vibration and vibration half squat position, respectively. The raw data were band pass filtered to remove noise and full wave rectified Paired sample t-test were performed to see the differences of maximum and average EMG between non-vibration and vibration trials. The results indicated that vibration produced much more muscle contraction than that of non-vibration trial for all selected muscles even though the significant difference was found only from Biceps Femoris. This phenomenon was due to the individual differences so care must be taken to evaluate vibration intensity and position before personal training.

Purpose: The purpose of this study is to examine the effects of postural control training using a horseback riding simulation on the spinal alignment of children with cerebral palsy. Methods: This study was conducted with 30 children with cerebral palsy at levels I~IV in the Gross Motor Function Classification System (GMFCS), and they were randomly divided into a control group and a hippotherapy group. Both the control group and the experimental group received NDT for 30 minutes per session, four times per week for ten weeks, while the experimental group also received hippotherapy 15 minutes per session, four times per week for ten weeks, after the neurodevelopmental treatment (NDT). The horseback riding simulators (JOBA, EU7805, Panasonic) used in this study simulated actual horse movements. Trunk imbalance, pelvic torsion, and pelvic tilt were measured in each group before the exercise and five weeks and ten weeks after the beginning of the exercise using a spinal structure analysis system (ABW Mapper). Results: The Intra-group effects on trunk imbalance, pelvic torsion, and pelvic tilt according to the exercise periods after the hippotherapy were tested, and the results showed significant interaction effects between the groups and the periods (p<0.05). Conclusion: The horseback riding simulation exercise was shown to be effective for the spinal alignment of children with cerebral palsy. Therefore, additional studies should be conducted with more children with CP divided by type.

In this paper, a study was conducted to estimate the maximum muscle strength which is a standard for selecting exercise intensity in weight training. We designed a device that estimates the muscle fatigue from the EMG signal, expecting to show a correlation between peak muscle strength and fatigue. Curl - Dumbbell was performed using a 4 kg dumbbell and the frequency change of the EMG was observed. At this time, the designed device acquires the signal using the MCU and finally Matlab was used to confirm the change in the center frequency value. The results of 10 subjects were analyzed using SPSS regression analysis. The statistical results showed a correlation of $R^2$ 0.583 and Significant probability of 0.010, and the relation of Y = 8.144-2.097 (slope (MDF)) was obtained. In conclusion, if the wearable device is manufactured in the form of a wearable device and the user can recommend the exercise intensity, the system will be able to retry the more efficient exercise.

An active training system has been developed to assist the upper extremity function in patients with spasticity. We also evaluated the performance of the developed assistive system in five normal subjects and one hemiplegic patient. The maximum voluntary contraction (MVC) tests for biceps brachii and triceps brachii were performed and the relationship between linear enveloped EMG signal and the elbow joint torque was found. In order to implement an active training, our system was designed to allow isokinetic movement only when the subject generates elbow joint motion larger than the pre-fixed threshold level. The proposed EMG-feedback control method could provide active exercises, resulting in better rehabilitation protocol for spastic patients.

Purpose: The purpose of this study was to investigate the effect of strengthening exercises of hip abductors on muscle strength and ambulation for patients with ACL reconstruction. Methods: The subjects were randomly assigned to the intervention group (general exercise plus strengthening of hip abductors) or the control group (general exercise without the strengthening of hip abductors). Both groups participated in a six-week exercise protocol after the surgery for ACL reconstruction. The knee strength test (quadriceps, hamstring, hip abductor) and gait analysis were performed in pretest and post-test. Results: Muscle strength was measured using the Biodex system III model (Biodex Medical System, Inc, NY, US). The results showed no significant difference in knee strength (quadriceps, hamstring) between the two groups (p>0.05), however, there was a significant difference in hip abductors (p<0.05). The gait analysis was measured with Gaitrite system (CIR System Inc, US). Results of comparison between groups showed a significant increase in the step length of both groups. (p<0.05), and there was a significant difference in the affected leg of the intervention group(p<0.05). Conclusion: Exercise of hip abductors for patients with ACL reconstruction provides significant benefits with respect to improvement of muscle strength in hip abductors, increasing the stride. This result indicates that a training program designed for ACL reconstruction patients should include strengthening of the hip abductor. We think that further study is needed to determine the relationship of hip muscles and knee joint for patients with ACL reconstruction.
