There is a pressing need for experimental measurements capable of testing chiral perturbation theory and other long distance effective theories. One of the most valuable quantities for performing
low $𝑄_2$ comparisons between experiment and theory is that of the nucleon spin structure function.
The spin structure functions $𝑔_1$ and $𝑔_2$ enable direct tests of effective theories of QCD through
their moments, and a series of sum rules involving their integration. The Thomas Jefferson National Accelerator (JLab) in Newport News, VA, USA, has hosted a highly successful and ongoing
program to measure these quantities over a broad kinematic range. In particular, the last few years
have produced newly published JLab results measuring these spin structure functions at low $𝑄_2$
for both the proton and the neutron. In this proceedings, these recent low $𝑄_2$ spin structure results
are summarized, along with prospects for future measurements.
