In this work, we have created one model with two stages.
Both of these stages are BPNN systems.
In the first stage, activated force is extracted from RSEMG signal.
This output will be used to calculate the mathematical estimated force by using Hill-type model.
We used this stage to train our BPNN model in the second stage.
In the second stage, the BPNN model will be used to extract the muscle force estimated value from the RSEMG signal.
