Simulated effect of a different posture. a, Example of muscle tuning curves obtained for the task performed with the forearm supinated (−80° from neutral position) or pronated (+80°). The arrows indicate the wrist direction used for reference (i.e., radial deviation). b, δ values, a measure of relative proximity to Msame and Msup (see Materials and Methods, Data analysis), indicate that muscle activities in post-blocks (Mpost) were closer to Msame than Msup for all subjects (n = 5).
