  • This study performed in order to investigate the effect of isometric resistance exercise for vastus medialis oblique muscle with EMG(electromyography) biofeedback training which are applied to the patello-femoral joint of patients with osteoarthritis on the improve of function. The subjects had no neuromuscular disorders, and they were elder patients with osteoarthritis, 20 women. And the experiment was performed in control group, taping with EMG biofeedback training group respectively, and the measurement was carried out before and after the treatment and 4 weeks after the treatment. Motor unit action potential analysis with surface electromyography showed a significant change in RMS(root mean square) amplitude and MDF(median frequency) in vastus medialis oblique muscle(p<0.05). VMO/VL(vastus medialis oblique/vastus lateralis oblique) MDF ratio showed a significant change between groups(p<0.05). Taping with EMG biofeedback training applied to patello-femoral joint of osteoarthritis patients appeared to be effective for muscle function improvement. However, increase of muscular force in vastus medialis oblique muscle appears to have a positive effect on improve of function along with correction effect on patella malalignment. In conclusion, in case of osteoarthritis patients with loss of patello-femoral joint function, it appears to be effective to practice isometric resistance exercise of vastus medialis oblique muscle selective with taping.

  • Purpose: This study investigated whether the strength imbalance between two muscles can affect the score of EMG based biofeedback game, and whether the EMG based biofeedback game score can be used as predictable indicator of the degree of muscle balance alternating the conventional strength measuring equipment. Methods: 40 participated in this study. Biodex was used to measure the peak torque/weight in order to calculate the muscle strength balance index between plantar flexor and dorsiflexor of ankle joint. And muscle balance index (MBI) was calculated. The EMG biofeedback game scores of dorsiflexor and plantar flexor were acquired, so that the EMG electrodes were attached at tibialis anterior and gastrocnemius. The relationship between the game score and the muscle balance index were analyzed. Results: There was negative correlation between the muscle balance index between plantar flexor and dorsiflexor and the peak torque/weight of plantar flexor (r=-0.70). And there was negative correlation between the muscle balance index between plantar flexor and dorsiflexor and the game score of plantar flexor (r=-0.83). Conclusion: The EMG biofeedback game score had significant relationship with muscle imbalance at ankle joint, so it seems that the game score can be used for predicting the degree of muscle imbalance as a parameter.

  • Insomnia is associated with numerous psychiatric and physical conditions, and hyperarousal is known to play an important role in the development of insomnia. There are a lot of limitations to use hypnotic medications for the treatment of insomnia. As psychological factors can greatly affect the development and progress of insomnia, several non-pharmacological treatment methods have been used for insomnia. Biofeedback is effective in the treatment of insomnia and its treatment effect lasts considerably long. Biofeedback together with relaxation techniques can reduce levels of arousal in insomnia patients so that they are effective for induction and maintenance of sleep. In conclusion, biofeedback treatment seems to be very helpful for insomnia patients who show high levels of arousal and have limitations in the use of hypnotic medications.

  • To reduce winging scapula, various exercise protocols have been widely used by clinicians. Selective serratus anterior strengthening, and restoring balanced function, are especially recommended to reduce winging scapula. The purpose of this study was to investigate visual biofeedback using a real time video camera display system for monitoring scapular winging during arm lowering. For this study, 13 males with winging scapular were recruited during arm lowering. Electromyography (EMG) activity was recorded from the serratus anterior (SA) and upper trapezius (UT) of the right side and compared with normal EMG activity using a paired t-test. The study showed, through visual biofeedback, that EMG activity significantly increased in the SA and significantly decreased in the UT (p<.05). These results suggest that visual biofeedback can be recommended as an effective method for scapular eccentric control, to prevent scapular winging during arm lowering.

  • Purpose: The purpose of the current study was to examine the effects of electromyography (EMG)-biofeedback training on lower extremity muscle activity and balance of patients with total knee replacement (TKR). Methods: Subjects were randomly allocated to two groups: experimental and control group. Subjects in the experimental group (n=10) were provided with quadriceps setting exercise by EMG-biofeedback (QSE+BF) and those in the control group were provided with QSE. Subjects in both groups were provided with the respective training programs for 20 minutes per session, five times per week, for a period of six weeks. To test significance, data analysis was performed using repeated-ANOVAs. Results: Statistically significant differences in muscle activity of the rectus femoris muscle and the vastus lateralis, and dynamic balance ability were observed in the experimental group, compared with the control group. In comparison of the muscle activity of the rectus femoris muscle and the vastus lateralis, and dynamic balance ability between different training periods within the groups, both groups showed statistically significant differences. Conclusion: EMG-biofeedback training is effective in improving lower extremity muscle activity and balance ability of patients with TKR, and should be effective in patients with other diseases.

  • Purpose: To improve self-management in elderly people with hypertension, the researcher examined the effects of an abdominal relaxed breathing exercises using biofeedback on blood pressure. These exercises regulate physical response to stress and lessen the activity of sympathetic nerves. Method: A single-experimental pre-and post-test design was used. Eight elderly people with hypertension participated in the study from April, 6 to June, 14, 2000. Biofeedback was done with soft ware by developed by J & J Company (1-410 form for abdominal respiration training). The abdominal relaxed breathing exercises are based on Mason's suggestion (1985) and were modified by Yu & Song(2001). This program consisted of 4 sessions once a week for four weeks. Data were analysed using SPSSPC+(10.0). Result: There was a significant decrease in systolic and diastolic blood pressure over three different times. There was a significant difference in the level of total stress response, overall health and quality of life but no significant difference in the level of emotional condition over three different times. Conclusion: The results of this study will contribute to the development of nursing strategies for the regulation of blood pressure in older people as the exercises are easy to learn and are a nonpharmacologic approach.

  • There is a growing need for a care system that can continuously monitor, manage and effectively relieve stress for modern people. In recent years, mobile healthcare devices capable of measuring heart rate have become popular, and many stress monitoring techniques using heart rate variability analysis have been actively proposed and commercialized. In addition, respiratory biofeedback methods are used to provide stress relieving services in environments using mobile healthcare devices. In this case, breathing information should be measured well to assess whether the user is doing well in biofeedback training. In this study, we extracted the heart beat interval signal from the PPG and used the oscillator based notch filter based on the IIR band pass filter to track the strongest frequency in the heart beat interval signal. The respiration signal was then estimated by filtering the heart beat interval signal with this frequency as the center frequency. Experimental results showed that the number of breathing could be measured accurately when the subject was guided to take a deep breath. Also, in the timeing measurement of inspiration and expiration, a time delay of about 1 second occurred. It is expected that this will provide a respiratory biofeedback service that can assess whether or not breathing exercise are performed well.
