  • Electroacupuncture (EA) is a modified form of acupuncture that utilizes electrical stimulation. We previously showed that EA stimulated rats were divided into responders that were sensitive to EA and non-responders that were insensitive to EA based on the tail flick latency (TFL) test. The dopamine beta-hydroxylase (DBH) gene was more abundantly expressed in the hypothalamus of responder rats than non-responder rats. To determine whether overexpression of DBH gene expression in the hypothalamus modulate EA analgesia, we constructed a DBH encoding adenovirus and which was then injected into the hypothalamus of SD rats. Microinjection of DBH or control GFP virus into the hypothalamus had no changes on the basal pain threshold measured by a TFL test without EA treatment. However, the analgesic effect of EA was significantly enhanced from seven days after microinjection of the DBH virus, but not after injection of the control GFP virus. DBH expression was significantly higher in the hypothalamus of DBH virus injected rat than control GFP virus or PBS injected rats. Moreover, expression of the DBH gene did not affect the body core temperature, body weight, motor function or learning and memory ability. Although the functional role of DBH in the hypothalamus in the analgesic effect of EA remains unclear, our findings suggest that expression of the DBH gene in the hypothalamus promotes EA analgesia without obvious side-effects.

  • Purpose: The purpose of study was to investigate effects of dance sports in virtual reality on balance, depression, and activities of daily living (ADL) in stroke patients. Methods: Subjects of the research consisted of 18 stroke patients who were randomly divided into the experimental and control groups, with nine patients each. All subjects underwent 30 minutes of Neurodevelopmental treatment (NDT) and 15 minutes of Functional electrical stimulation (FES) five days per week for a period of six weeks. Subjects in the experimental group performed an extra 30 minutes of dance sports in virtual reality each day. Balance, depression, and ADL of patients before and after the experiment were measured using Berg's balance scale (BBS), Beck depression inventory (BDI), and Modified Barthel index (MBI), respectively. For comparisone of the state before and after the experiment, wilcoxon signed ranks test was applied and for comparison of the difference between the groups, mannn-whitney U test was applied. Results: Results of this study, showed significant difference in balance, depression, and ADL between the experimental and control groups(p<0.05). As a control of the two groups, the experimental group, which performed extra dance sports in virtual reality, showed a significant difference in balance, depression, and ADL(p<0.05). Conclusion: Depending on the result, a dance sport in virtual reality was verified to enhance balance, depression, and ADL in stroke patients. Therefore, from now on, need for effective program development and application using dance sports in virtual reality will arise.

  • Chronic postsurgical pain (CPSP) is an unwanted adverse event in any operation. It leads to functional limitations and psychological trauma for patients, and leaves the operative team with feelings of failure and humiliation. Therefore, it is crucial that preventive strategies for CPSP are considered in high-risk operations. Various techniques have been implemented to reduce the risk with variable success. Identifying the risk factors for each patient and applying a timely preventive strategy may help patients avoid the distress of chronic pain. The preventive strategies include modification of the surgical technique, good pain control throughout the perioperative period, and preoperative psychological intervention focusing on the psychosocial and cognitive risk factors. Appropriate management of CPSP patients is also necessary to reduce their suffering. CPSP usually has a neuropathic pain component; therefore, the current recommendations are based on data on chronic neuropathic pain. Hence, voltage-dependent calcium channel antagonists, antidepressants, topical lidocaine and topical capsaicin are the main pharmacological treatments. Paracetamol, NSAIDs and weak opioids can be used according to symptom severity, but strong opioids should be used with great caution and are not recommended. Other drugs that may be helpful are ketamine, clonidine, and intravenous lidocaine infusion. For patients with failed pharmacological treatment, consideration should be given to pain interventions; examples include transcutaneous electrical nerve stimulation, botulinum toxin injections, pulsed radiofrequency, nerve blocks, nerve ablation, neuromodulation and surgical management. Physical therapy, cognitive behavioral therapy and lifestyle modifications are also useful for relieving the pain and distress experienced by CPSP patients.

  • Background: This study had been carried out with 18 ischemic stroke patients as its object for about eight months from October, 2006 to May, 2007 in order to observe the recovery of motor function and the change of important blood factors according to the different quantitative exercises. Methods: Subjects were assigned randomly either experimental group (n=19) or the control group (n=19), when the study began the halfway on this study dropout 20 patients, and final subjects remained experimental group's 9 patients and control group's 9 patients. Both groups received thermotherapy and functional electrical stimulation (FES), also taken different quantitative exercise therapy (experimental group 180 minutes, control group 80 minutes). Subjects were assessed for upper and lower extremities motor function Fugl-Meyer Scale; FMS), blood test (white blood count; WBC, low density lipoprotein -cholesterol; LDL-C, high density lipoprotein-cholesterol; HDL-C, Troponin) during pretest, after 2 months, after 3 months. Results: The results of this study were as follows; 1. FMS has no statistically significant difference with intergroup(p>.05). But there was a statistically significant difference with each groups (p<.05). 2. WBC has no statistically significant difference with intergroup (p>.05). But there was a statistically significant difference in control group (p<.05), without experimental group (p>.05). 3. LDL-C has no statistically significant difference with intergroup (p>.05). But there was a statistically significant difference in control group (p<.05), without experimental group (p>.05). 4. HDL-C has no statistically significant difference with intergroup (p<.05). But there was a statistically significant difference with each groups (p>.05). 5. Troponin Ⅰ has no statistically significant difference with intergroup (p>.05). Also there was no statistically significant difference with each groups (p>.05). Conclusion: These findings suggest that different quantitative exercises has no effect on FMS, LDL-C, HDL-C, WBC, Troponin Ⅰ with ischemic stroke patients. But the treatment period that there's less correlation between the recovery of motor function and the different quantitative exercise, also less correlation between the change of important blood factors and the different quantitative exercises with ischemic stroke patients.

  • Background: Hemiplegic patients usually have difficulty maintaining balance. Balance training is a major component of there habilitation program for patients with neurological impairment. The purpose of this study was to investigate the effects of PLS(Posterior Leaf Spring), FES(Functional Electrical stimulation), treadmill training, and neurodevelopmental treatment on the improvement of balance in patients with hemiplegia. Methods: We looked into published studies from Dankook University’s electronic library databases of RISS4U, KMbase, NCBI, and MEDLIS concerning the effectiveness of any form of intervention leading to improvement of balance. All types of studies relevant to the topic that were published in English during the time period of 1986 to 2005 were included. Results: 1. There were significant differences in standing balance, dynamic activity balance, and gait speed between barefoot subjects and subjects who wore SPAFO and HPAFO(p<.05). 2. The changes in ROM and FRT related to sex, age, height, and weight part of the diagnosis, as well as experience relapse, was of meaningless value. Changes in ROM related to the duration of pain and experiences of falling down were also meaningless. However, FRT showed significant static differences(p<.05). 3. The body-weight-support treadmill training scoring of standing balance, step length, and a timed 10m walking test showed definite improvement. 4. The proprioceptive control approach improved dynamic balance in patients with hemiplegia. Conclusion: Consequently, further study is needed to verify methods when physical therapists are researching balance ability in hemiplegic patient.

  • Purpose: The purpose of this study was to evaluate the effect of task-oriented exercise and abdominal muscle contraction using functional electrical stimulation (FES) on abdominal muscle thickness and balance of stroke patients. Methods: Ten stroke patients who met the selection criteria were assigned randomly into two groups of five. One group received FES therapy before task-oriented training (experimental group), while the other group received a FES placebo before task-oriented training (control group). The Mann-Whitney U test was used to compare the groups, and the Wilcoxon Signed-ranks test was used to compare differences between the groups before and after intervention. The Mann-Whitney U test was used to compare the rate changes of each item before and after intervention, between the two groups. Results: In the rectus abdominalis and external oblique muscle thickness tests that used ultrasound, there was a statistically significant difference in the experimental group (p<.05),but no significant difference in the control group (p>.05). There was also a significant difference between the groups (p<.05). In the Balance test that used the Berg Balance Scale (BBS) and timed up and go test (TUG), there was a statistically significant difference in the experimental and control groups (p<.05), but there was no significant difference between the groups (p>.05). Conclusions: FES therapy before task-oriented training increases the thickness of abdominal muscles and improves balance abilities.

  • Objective: This study was conducted to analyze the effect of wearable Electromyography-controlled functional electrical stimulation (EMG-controlled FES) System on Gait Function and cardiopulmonary metabolic efficiency during walking in older adults. Design: Cross-section study Methods: Total 22 older adult participants suitable to selection criteria of this study participated in this study. The EMG-controlled FES System, which functions as a wearable physical activity assist FES system was used. All participations performed randomly assigned two conditions (Non-FES assist [NFA], FES assist [FA]) of walking. In all conditions, spatio-temporal parameters and kinematics and kinetics parameters during walking was collected via 3D motion capture system and 6 minutes walking test (6MWT) and metabolic cost during walking and stairs climbing was collected via a portable metabolic device (COSMED K5, COSMED Srl, Roma, Italy). Results: In Spatio-temporal parameters aspects, The EMG-controlled FES system significantly improved gait functions measurements of older adults with sarcopenia at walking in comparison to the NFA condition (P<0.05). Hip, knee and ankle joint range of motion increased at walking in FA condition compared to the NFA condition (P<0.05). In the FA condition, moment and ground reaction force was changed like normal gait during walking of older adults in comparison to the NFA condition (P<0.05). The EMG-controlled FES system significantly reduced net cardiopulmonary metabolic energy cost, net energy expenditure measurement at stairs climbing (P<0.05). Conclusions: This study demonstrated that EMG-controlled FES is a potentially useful gait-assist system for improving gait function by making joint range of motion and moment properly.
