• A threshold theorem previously discussed by Oleson and Pietschmann on π-N scattering is extended to π-hadron scattering in general, including π-π scattering. We recover in a comprehensive manner the π-hadron and π-π scattering lengths obtained previously by the PCAC technique. The method to obtain the threshold theorem is also applied to π-nucleus systems: We derive a new sum rule on the π-nucleus scattering length and a relation between the π-nuleus effective coupling constant and the π-N coupling constant.
