Knee extension deficit is frequently observed after anterior cruciate ligament reconstruction or rupture and other acute knee injuries. Loss of terminal extension often occurs because of hamstring contracture and quadriceps inactivation rather than mechanical intra-articular pathology. Failure to regain full extension in the first few weeks after anterior cruciate ligament reconstruction is a recognized risk factor for adverse long-term outcomes, and therefore, it is important to try to address it. In this Technical Note, a simple, rapid, and effective technique to help regain full knee extension and abolish quadriceps activation failure is described.

Renewable energies are currently considered as a tool for mitigating climate change. Therefore, wind energy corresponds to one of the methods that provides energy in a clean way, using different models of wind turbines, allowing to identify strategic points from obtaining variables such as wind speed, location, and models, through the which can reduce the negative impact generated by conventional energies. Therefore, to properly take advantage of this type of energy it is important to identify the municipalities that meet the appropriate speed ranges, in addition to the analysis of the area that allows establishing the appropriate generators so as not to alter the balance of the ecosystem contributing to environmental mitigation, partne r - economical.
