CRET is effective for improving pain and healing injured tissue;however, its influence on muscle function and morphology is still unclear. This study confirmed the immediate effects of CRET on the duration of muscular stiffness and range of motion (ROM). [Method] This study describes the protocol for a single-arm trial with the non-blinding of participants and researchers. Twenty-four healthy men participated in the study. They received CRET therapy for their low back areas. The muscular stiffness of the multifidus muscle (superficial and deep) and the ROM using the active straight leg raise (ASLR) test were measured pre-intervention, post-intervention (immediately), and 15 and 30 min post-intervention. We compared these parameters using a one-way analysis of variance and Dunnett’s test (multiple comparison tests for subtests). [Results] The muscular stiffness of the superficial and deep multifidus muscles was significantly decreased, and the ASLR test showed a significant increase compared with the test performed pre-intervention. In addition, these effects persisted for 30 min. [Conclusion] Warm-up is vital for improving muscular stiffness and increasing the ROM. CRET is a useful device for achieving these aims, particularly as a passive warm-up method in sports settings.展开更多

The objective of this study was to identify the effects of Tecartherapy on healthy and unhealthy tissues. A systematic review of Tecartherapy technology was carried out. Articles published up to the year 2023 were investigated. The search argument used was “Capacitive-resistive electrical transfer” OR “Tecar” OR “Therapy Tecar” OR “CRET” in the BVS, Cochrane, PEDro, PubMed, IEEE Explore databases, Scielo and Web of Science. As for the main results of using Tecartherapy, there is an increase in temperature. In healthy tissues there is an increase in local blood flow, a decrease in muscle fatigue and an increase in muscle flexibility. In addition to the effects observed on healthy tissues, pain reduction and improved joint function were also observed. It was concluded that this technology has similar effects to other diathermy, but Tecartherapy proved to be safer and more comfortable. .展开更多

Carbon and nitrogen removal can be achieved by utilizing the electron transfer between the anode and cathode in an MFC. However,large-scale power production and high removal efficiency must be achieved at a low cost to make MFCs practical and economically competitive in the future. This article reviews the principles, feasibility and bottlenecks of MFCs for simultaneous carbon and nitrogen removal, the recent advances and prospective strategies for performance improvement, as well as the involved microbes and electron transfer mechanisms.展开更多
