Both Dr. Fishman's study and the 2016 - study by Motorwala quoted above used a wide range of postures, including twisting postures

Poses
like Virabhadrasana 2, Utthita Parsvakonasana and versions of clam shell will contract the piriformis, while simple standing twist with a chair and
Ardha Matsyendrasana would be good options for stretching it (since they place your leg into flexed / adducted position without the external rotation element, which is milder for piriformis).
