Purpose: The aim of this study was to describe and understand the experiences of pain and the perceptions of treatment through a traditional Korean medicine clinical trial in patients with non-acute pain after back surgery. Methods: The data collection was recorded through in-depth interviews with 20 participants and transcribed with verbatim. The data were analyzed with qualitative contents analysis. Results: Patients with persistent or recurring pain after back surgery experienced physical and psychological symptoms that resulted in severe difficulties in daily and working life. Their persistent or recurring pain after surgery was a burden in their life and a major source of depression. Because of the difference in the perception of pain between doctors and patients, the patients continuously sought and received various treatments. The patients also wanted to receive customized self-management in exercise so that they could control pain themselves in daily life. Conclusion: A multidisciplinary approach that includes psychological counseling, pain management, individualized exercise, and education for proper posture should be needed to reduce low back pain in patients with pain after back surgery.

Alzheimer’s disease (AD) is an irreversible and progressive neurodegenerative disease accompanied by aging, followed by memory impairment and cognitive decline. Although numerous attempts have been made to develop treatments for AD, most clinical trials have failed to delay or stop the progression of AD. Electroacupuncture (EA) is a complementary alternative medicine technique widely used to treat pain, inflammation, and neurodegenerative diseases. Additionally, blood-brain barrier (BBB) disruption is a known pathophysiology of neurodegenerative diseases, including AD. Moreover, amyloid beta deposition increases BBB permeability and produces inflammatory cytokines induced by glial activation. However, our previous study revealed that EA treatment at the Taegye acupoints (KI3) improves memory impairment through anti-neuroinflammation and increases glucose metabolism in 5XFAD mice. Therefore, we evaluated whether EA treatment at KI3 regulates BBB dysfunction in the prefrontal cortex of 5XFAD mice. For this study, 6.5-month-old 5XFAD mice were treated with EA stimulation at KI3 three times a week for two weeks. Western blotting, immunohistochemistry, and flow cytometry were used to evaluate the effects of EA treatment on BBB dysfunction. We found that EA stimulation attenuates BBB integrity by protecting BBB tight junction proteins (CD31, aquaporin 4, occludin, and claudin 5) in the prefrontal cortex of 5XFAD mice. In addition, EA treatment regulated inflammatory cytokines (IL-1α, IL-1β, IL-17, IL-23, IFN-ɣ, monocyte chemoattractant protein 1 (MCP-1), granulocyte-macrophage colony stimulating factors [GM-CSF], and IL-10) in the peripheral circulation of 5XFAD mice. Therefore, our data suggest that EA treatment could be a therapeutic agent for enhancing BBB dysfunction in AD.

This study was designed to examine the effects of electroacupuncture and treadmill exercise on the improvement of muscle atrophy and Brain-Derived Neurotrophic Factor (BDNF) expression in an ischemic stroke model induced by middle cerebral artery occlusion. This study selected 120 Sprangue-Dawley rats, divided them into six groups, and assigned 5 rats to each group. Experiments were conducted for 1, 3 days and 1, 8 weeks, respectively. In each group, changes in weight of muscle and relative muscle of tibialis anterior muscle, histologic observations, and BDNF expression were observed and analyzed. For the changes in muscle weight of unaffected and affected sides of tibialis anterior, muscle atrophy was expressed in an affected side 3 days after ischemic stroke was induced. There was a statistically significant difference in Group VI 1 and 8 weeks after ischemic stroke was induced, compared to Group II (p<.05). For the changes in relative muscle weight of unaffected and affected sides of tibial anterior muscle, there was significant decrease in each group 3 days after ischemic stroke was induced, compared to Group I, while there was a statistically significant increase in Group VI 1 week after ischemic stroke was induced, compared to Group II (p<.05). For neurologic exercise behavior test, Group VI generally had the highest score, compared to other groups. The results of the behavior test suggests that 8 weeks after ischemic stroke was induced, Group VI improved in degeneration and inflammation of muscle fiber and decreased in destruction of nerve cells and cerebral infarction, thus indicating a similar state of muscle fiber and brain tissue in Group I. In immunohistochemical observations, Group 1 week showed increase in BDNF. Based on these results, electroacupuncture and treadmill exercise may improve muscle atrophy and change in BDNF expression of ischemic stroke rats and contribute to the improvement of exercise function.

Skeletal muscle injury occurs frequently in sports medicine and is the most general form of injury followed by physical impact. There are growth factors which conduct proliferation, differentiation, and synthesis of myogenic prodromal cells and regulate vascular generation for the continued survival of myocytes. The purpose of the present study was to confirm the effects of electroacupuncture (EA) and electrical stimulation (ES) on muscle recovery processes according to vascular endothelial growth factor (VEGF) expression. Eighteen Sprague-Dawley rats were separated into 2 experimental groups and a controlled group. All animals had suffered from crush damage in the extensor digitorum longus for 30 seconds and were killed 1, 3, and 7 days after injury. 30 Hz and 1 mA impulsion for 15 minutes was applied to the EA experimental groups Zusanli (ST36) and Taichong (LR3) using electroacupuncture and the same stimulation was applied to the ES group using an electrical node. Hematoxyline-Eosin staining and VEGF immunohistochemistry were used to ascertain the resulting muscle recovery. There were few morphological differences between the EA and ES groups, and both groups were observed to have tendencies to decrease atrophy as time passed. In the controlled group, gradually diminishing atrophy could be observed, but their forms were mostly disheveled. There were few differences in VEGF expression between the EA and ES groups, and tendencies to have an increased quantity of VEGF with the lapse of time were observed in both groups. In the controlled group, a little VEGF expression could be observed merely 7 days after injury. In conclusion, EA and ES contributed to muscle recovery processes and could be used for the treatment of muscle injury.
