Many people have experienced or at least heard of sciatica. This is the condition whereby either compression of the L4‐S1 nerve roots affects the sciatic distribution or the sciatic nerve is injured as it exits the buttocks. It can also be influenced by the piriformis muscle, which originates on the anterior of the sacrum and passes under the sciatic notch, inserting on the top of the greater trochanter. The piriformis functions in lateral rotation of the thigh.Many practitioners with tight hips and/or weak and tight lower‐back muscles will find that straight‐leg forward bends aggravate or even create sciatica. If the pelvis is unable to rotate forward (flexion of the hip) by the psoas and iliacus muscles, quadratus lumborum, and rectus abdominis, then ante‐version or rotation of the pelvis forward will be limited, resulting in the pelvis rotating back (retroversion).
