This review focuses on an insightful analysis of the data acquisition system of EMG signals from these interfaces. According to applications reported in research articles of the last five years, the properties of the sensors, the number of channels, the pre-processing of the EMG signal, as well as the software and hardware used were identified. This analysis was performed for the following applications: monitoring of muscular activation for rehabilitation, muscle activation plans, and identification of possible pathologies, exoskeletons, electric of wheelchairs, prosthetics control, myoelectric bracelets, handwriting recognition and silent speech recognition. The results presented in this review become a guide of recommendations for the myoelectric signal processing according to the application of the interface. The main developments, degrees of research and open challenges are also presented in this direction.

After identification of problems and prioritization, interchangeability based only on economic criteria was the main problem to be confronted. The primary objective of this study was to identify political options to approach the problem of interchangeability in systematic reviews.MethodsWe conducted a rapid evidence synthesis for policy based on an adaptation of the SUPPORT tools, and searched in six literature databases. The selection of studies was performed in a systematic, transparent and independent manner. The International Network of Agencies in Health Technology Assessment (INAHTA) members were consulted to learn how this practice occurs worldwide.ResultsWe included seven systematic reviews and one policy brief, whose options to a...

Currently, the network is composed of 119 member institutions and mobilizes approximately 1,094 researchers and 4,998 relations. The objective of this study was to evaluate the member institutions of REBRATS.MethodsThe evaluation process was developed in seven stages, including the identification of the objectives of the Network; identification of evaluation criteria; selection of performance indicators for each criterion; identification of the measures appropriate to each indicator; data collection and analysis; classification of the institutions and production of the final report.ResultsThe evaluation of the member institutions of REBRATS mapped the capacity of these institutions to produce health technology assessment ac...

Decit has provided methodological support to the working group, conducting a rapid review and a rapid evidence synthesis to subsidize decisions and recommendations.MethodsWe used the Methodological Guidelines for the Elaboration of Evidence Synthesis for Health Policies, which is a product of our own team, based on the SUPporting POlicy relevant Reviews and Trials (SUPPORT) Tools for evidence-informed health Policymaking.ResultsThe Decit team participated in the key steps to develop an evidence-informed policy. Our product, “Barriers to Access to Biologic Products: a Rapid Review” was used for the prioritization of health problems and the description of the problem. We then proceeded to the evidence synthesis planning and definition of the research question from an acronym. Together with the coordination of the w...
