Negative values indicate flexion direction for the torque, anterior direction for Fx, and upward direction for Fz.

^a = significant difference between small and medium amplitude movements within phase.

^b = significant difference between small and large amplitude movements within phase.

^c = significant difference between medium and large amplitude movements within phase.

* = significant difference between acceleration and deceleration phases within movement amplitude.
