Initial TVR-evoked torque development is invariant to preactivation magnitude in the non-paretic but not the paretic limb. Blue trace: non-paretic limb at 15% MVT preactivation; pink trace: paretic limb; black traces: optimal fits of an exponential composition to paretic and non-paretic data, respectively; purple traces: overlay of optimal fit of each limb's TVR-evoked torque at 5% MVT preactivation onto the 15% MVT preactivation records. In the non-paretic limb, the optimal fit at 5% MVT is able to explain ~98% of the variance in the torque response at 15% MVT preactivation. Conversely, the 5% MVT fit is only able to explain ~75% of the variance in torque response at 15% MVT in the paretic limb.
