Figure 5. Averaged heteronymous SLR and LLR waveforms recorded from the FDI muscle by stimulating the median nerve during the force (blue line) and position tasks (red line) (A), and the mean amplitude of the SLRs (B) and LLRs (C).

The amplitude of both the SLRs and LLRs during the position task was significantly larger than during the force task (mean ± SEM). (** p<0.01).
