Validation of an EMG measuring system based on upper body muscles

When working with power tools, users sometimes experience high forces that can lead to health problems. There are many different approaches for designing products more ergonomically. In particular, computer simulations are becoming increasingly important. Compared to conventional methods, musculoskeletal human models can be used to investigate, e.g., joint forces and muscle activation with reduced effort. To validate models and simulation results, simulated muscle activation is often compared to experimental captured data. However, the measured EMG data is first to be validated to draw valid conclusions regarding user loads.
