Review of Modelling Techniques for In Vivo Muscle Force Estimation in the Lower Extremities during Strength Training

Table 1

Four concepts of search parameters were used to systematically search the literature and were combined using an “and” condition (horizontal). Each concept was created using “or” conditions (vertical) in order to ensure the inclusion of all papers using similar definition for the same case.
