Sensitivity analysis of the model. (a) The model is sensitive to changes in the load but is relatively invariant to changes in acceleration and bubble radius. (b) The model gives physiologically consistent results but is also sensitive to changes in the geometry as shown by varying the geometry through half a standard deviation (σ m = 1.08, σ p = 2.30) above or below the mean metacarpal and proximal phalanx radii. The model diverged for the case of R m − 0.5σ m , R p + 0.5σ p above a load of 6 N.
