• Before planning the treatment, determine the position of comfort or symptom reduction i.e FUNCTIONAL POSITION. The patient may have,
• (a) Extension bias: Patient’s symptoms are lessened in position of extension (bending back) and provoked in flexion (bending forwards) e.g PIVD.
• (b) Flexion bias: Patient’s symptoms are lessened in position of spinal flexion (bending forwards) and provoked in spinal extension (bending backwards) e.g spinal stenosis, spondylolisthesis.
