In this talk, we report on the first simultaneous extraction of the worm-gear function $g_{1T}$, one of the eight leading-twist TMDs. The study analyzes HERMES, COMPASS and JLab semi-inclusive deep-inelastic scattering data using Monte Carlo techniques. We provide a comparison of $g_{1T}$ obtained from this experimental data with lattice QCD calculations, a large $N_{c}$ analysis, and the Wandzura-Wilczek-type approximation.
