The effects of gluteal stretching <i>vs</i>. Lightback® on hip rotation range of motion and posterior chain flexibility in healthy subjects: a cross-over clinical trial

This study demonstrated that both the Lightback system and static gluteal stretching improved passive hip ROM. However, the Lightback system showed greater improvements in active ROM, particularly in external and internal rotation at various degrees of hip flexion, as well as in posterior chain flexibility. Notably, the Lightback system significantly enhanced large improvement in the ASLR test.
