Shape-model constrained scaling may improve repeatability of gait data generated by opensim

Scaling approach can vary between modellers, which in turn can affect the results of gait analysis. We hypothesised that the use of the MAP Client (developed at the ABI) could reduce the variability between modellers for the same subject motion data. After having multiple scalers use both this tool and OpenSim’s built-in scaling, we found reduced variability between scalers using MAP Client compared to OpenSim Scaling.
