Purpose: The purpose of this study was to compare the effects of scrambler and transcutaneous electrical nerve stimulation therapy on pain, functional disability, and depression in patients with chronic low back pain. Methods: Twenty patients with chronic stroke were assigned randomly to an experimental (n=10) or control (n=10) group. The experimental group performed scrambler therapy. The control group performed electrical nerve stimulation therapy. Training was conducted once a day for 30 minutes, five days per week, for three weeks. The pain was measured using the numeric rating scale. Functional disability was measured using the Roland-Morris disability questionnaire. Depression was measured using the Beck depression inventory. Results: As a result of comparison between the groups, the experimental and control groups showed significant difference for pain, functional disability and depression after the experiment (p<0.05). In a comparison between the two groups, the experimental group, in which scrambler therapy was applied, showed a more significant reduction in pain, functional disability and depression than the control group (p<0.05). Conclusion: Based on these results, scrambler therapy shows positive effects on pain, functional disability, and depression in patients with chronic low back pain.

Objectives The purpose of this study was to evaluate the most effective stimulating electrode in Microcurrent electrical neuromuscular stimulation (MENS) for pain relief, and to apply to the treatment of Delayed onset muscle soreness (DOMS). Methods We included 45 participants who met the inclusion criteria. DOMS of both Triceps Surae Muscles were experimentally induced through eccentric contractions. 24-hours after induction of DOMS, who scored more than 40 mm in visual analogue scale (VAS) were randomly assigned into three groups (n=44). In 15 of them, needle electrodes were inserted into BL57, BL56. In 15 of them, surface electrodes were applied on the same points and the others were treated with manual acupuncture. The effects of pain relief were assessed by visual analogue scale (VAS), mechanical pain threshold (MPT), surface electromyography (SEMG). Results In VAS, group comparison had no significant difference after all treatments had done. The difference in VAS between the time before the treatment was started (Day 2) and after all treatments were completed was greater in Acupuncture group than that of needle-electrode group. In MPT, there was no significant difference among groups. Electrical contraction decreased significantly at 2nd before-after treatment comparison in needle-electrode MENS group. But fatigue scores were not significantly different between groups. Conclusions The results suggest that the types of electrodes has no significant effect on microcurrent therapy in DOMS.

The purpose of this study was to determine the effect of muscle contraction torque and muscle fatigue by low-frequency PC. In this article, We would like to experiment on electrical stimulation, determine optimal forms of stimulation setting. We used normal fourteen subjects(seven women, seven men) without neuromuscular disease and all subjects participated in the 3 session. Torque was measured using a computerized Kin-Com dynamometer for MVIC, MIC, Fatigue tests. The following results were obtained; 1. Torque of man were significantly higher than women in the MIC test(p<.05). 2. Torque of women, man were significantly decreased in the Fatigue test(p<.001). Between woman and man groups were significant difference(p<.05). These results lead us to the conclusion that muscle fatigue was influenced by PC, fatigue of women was higher than man. Therefore, A further studies concerning the electrical stimulation should consider differences between sexes in response to treatment and could enhance the development of the most effective treatment regimens.

Electrosurgery has been widely used in surgical procedures for many years. The surgical procedure using radiofrequency power generated occasionally sparks causing electrical stimulations. According to a paper of commercialized APC (Argon Plasma Coagulation) in the gastrointestinal endoscopy, Patients treated by APC had experienced pain and neuromuscular stimulation. This study aimed to investigate the electrosurgery sparks. In this experiment, current threshold of electrosurgery using rf was investigated. Sparks analogous to surgical situation was generated and measured the I-V figure. Asymmetric current, observed by other researchers, was also measured. This could be explained by difference between positive phase and negative phase. Furthermore, a method was developed to remove asymmetric current and to make safer device for surgical field.

Purpose: This study aims to investigate the changes in pulmonary function, gait ability, and quality of life when NMES is applied along with CBE and to provide basic clinical data to be used in pulmonary rehabilitation guidelines for patients with COPD to treat patients with severe COPD. Methods: For this study, CBE and NMES of quadriceps femoris on both sides were applied to the experimental group (n=10), and only CBE was applied to the control group (n=10). For a pre-test, a 6-minute walk test was performed, and pulmonary function and health-related quality of life were measured. Moreover, an exercise program was applied to each group for 30 minutes per session, 5 times a week, for 6 weeks. After that, a post-test was conducted the same way as the pre-test. Results: In the within-group comparison, there were significant differences in forced expiratory volume in one second, 6-minute walk test and health-related quality of life between the experimental group and the control group (p<0.01)(p<0.05). In the between-group comparison, the experimental group showed an increase in forced expiratory volume in one second and 6-minute walk test (p<0.05) and showed a decline in health-related quality of life (p<0.05). Conclusion: The 6-weeks NMES program improved health-related quality in patients with severe COPD by increasing expiratory volume by reinforcing the function of quadriceps femoris. This finding implies that NMES could be an alternative mode for improving physical functions of patients with severe COPD, who cannot participate in a breathing exercise program or are reluctant to participate.

PURPOSE: To solve the problems of chronic obstructive pulmonary disease (COPD) patients complaining of muscle fatigue and having limited motor abilities, this study provided the clinical basic data for pulmonary rehabilitation by examining the effects of High Low-Frequency Neuromuscular Electrical Stimulation (NMES) on the respiratory muscle strength, quadriceps muscle activity, and life quality. METHODS: Samples were collected from 20 COPD patients and placed randomly in a low-frequency group (n=10) and high-frequency group (n=10). For a pretest, the respiratory muscle strength (MIP, MEP), quadriceps muscle activity (LF, VM, VL), and life quality (SGRQ) were measured. After applying NMES to each group for 30 minutes at a time, five times a week, for four weeks, a posttest was conducted in the same way as the pretest. RESULTS: Both groups showed significant differences in the respiratory muscle strength, quadriceps muscle activity, and quality of life within the groups and there were significant differences in the quadriceps muscle activity between the groups. CONCLUSION: The four-weeks NMES positively influenced the respiratory muscle strength and life quality by enhancing the function of the quadriceps and exercise tolerance. In particular, high-frequency(75 Hz) NMES was more effective than low-frequency (15 Hz) NMES. This result can be an alternative means to improve the physical functions of COPD patients clinically in the future.

Objectives : The aim of this study is to review clinical studies of facial palsy sequelae treatment Methods : We used search engines such as PUBMED, OASIS, RISS. We limited sequelae as the cases after three months from the onset. We excluded the studies including operational treatments. We considered papers pubulished only after year 2000. Results : The kinds of treatments were acupunture treatment, physical therapy, Botulinum toxin, and steroids and antiviral agent. Four studies about acupuncture treatment were searched. Two were case studies and the other two were case series studies. Six studies about physical therapy were searched and they were devided into three according to their specific methods - neuromuscular training and biofeedback, electrical stimulation, and facial exercises. We reviewed three studies about Botulinum toxin and 3 studies about combined therapy. Conclusions : Evidence level of the acupuncture studies was not high. Neuromuscular retraining and biofeedback therapies were shown to be effective especially to synkinesis. Mime therapy, one of the facial exercise has significant effect. Electrical stimulation is thought to activate the plasticity of central nerve system. Botulimum Toxin has effective temporary treatment. Steroid therapy increases recovery rate and reduces sequelae.
