Background : Low back pain (LBP) can cause changes in muscle activity in affected individuals, making it difficult for them to contract their muscles effectively and engage in physical activities. Manual chiropractic techniques have been proposed as a potential solution to improve muscle orientation and function in individuals with LBP. Aim: The purpose of this study was to investigate the effect of manual techniques on maximum muscle activity electromyography, functional disability, and pain in women with non-specific chronic low back pain. Materials and Methods: Twenty women between the ages of 30 and 50, who had been experiencing NSCLBP for over three months with no history of spinal surgery or postural abnormalities, and were able to perform daily activities after providing consent, were recruited from a sports medicine clinic to participate in the study. In the pre-test, the Oswestry Disability Index (ODI) was used to assess functional disability, and the Visual Analogue Scale (VAS) was used to assess pain levels. Additionally, the maximum muscle activity of the multifidus and lumbar quadratus lumborum (QL) was measured using EMG. Chiropractic manipulation techniques were then implemented in the experimental group, with three sessions per week for six weeks, within the clinic. The same tests were repeated in the post-test. The ANOVA test was used to compare the chiropractic and control groups, with a significance level of α ≤ 0.05. Results : The study results indicate that chiropractic manual techniques were effective in reducing lumbar EMG activity ( P = 0.0001), reducing pain index ( P = 0.002), and improving functional disability ( P = 0.001) significantly. Conclusion : The study findings suggest that six weeks of chiropractic manipulation techniques can induce a feeling of relaxation, reduce pain, and passively strengthen the lumbar muscles. These improvements in muscle condition and functional disability may lead to a reduction in pain experienced by individuals with NSCLBP.

Purpose: Skin is the most important organ of the body and maintains its integrity is critical in good health. Severe skin damage is life-threatening and repairing restores its tissue integrity and delay in it endangers health. According to the importance of wound healing and the fact that not treated wounds may decrease quality of life, many studies have investigated the effect of some natural and chemical substance on the length and quality of wound healing to find out beneficial interventions that rapidly and economically treat it. This review aimed to describe the physiology of cutaneous wound healing and some negative and positive factor with a focus on exercise. Methods: An electronic search without any time limitation was performed on the PubMed, Google scholar and web of science databases to find published articles in English. The keywords were wound healing, exercise, and physiology. According to relation to subject, similarities, and differences 48 articles were selected and reviewed. Results: wound healing is a complicated physiology process that consists of four consecutive overlapping stages. Disruption in each stage disturbs wound healing. Many chemical and herbal compounds are used to speed up wound recovery due to their anti-inflammatory property. Exercise is one of the effective factors in wound healing and many studies evaluated effect of different protocol of exercise on it. The results of studies show that aerobic exercise due to its anti-inflammatory and antioxidative effect is a beneficial method in shortening the length of wound healing, especially in aged, fat, and diabetic individuals. Conclusion: Moderate intensity aerobic exercise as a complementary medicine is a good intervention in the treatment of impaired and chronic wounds.

Purpose: The objective of this study is to analyse various articles on the effect of various types of exercise on the angiopoietins family and angiopoietin-like proteins (ANGPTLs). Methods: PubMed, Science Direct, Scopus and Google Scholar databases were searched from 2000 to September 2020. After screening the articles, 19 articles that met the inclusion criteria were studied and analysed. Results: In our body, four types of angiopoietin and eight types of angiopoietin-like proteins have been identified, the functional method of some of them which are still not entirely understood. Angiopoietin-1 and angiopoietin-2 are essential regulators of vascular formation and maintenance. Angiopoietin-1 is found in perivascular and vascular cells within and around smooth muscle cells and plays an important role in growth, vascular stability, and pathological angiogenesis. On the other hand, angiopoietin-2 and angiopoietin-3 are mainly involved in inducing vascular regression, cell death, and inflammation. Angiopoietin-4, like angiopoietin-1, is responsible for the maturation, stabilization, and stasis of blood vessels. Conclusion: Studies show that exercise has a significant effect on increasing capillary density in the human body by increasing angiopoietin as one of the angiogenesis factors. In addition, there are many other benefits such as contribution to fat burning and treatment of coronary artery disease, cancer, asthma, and ischemia. More research is needed on the effects of different types of exercise training on angiopoietins.
