The erector spinae paraspinal musculature is stretched with flexion of the spine. To better stretch one side, opposite-side (contralateral) lateral flexion can be added.
The erector spinae group is composed of the:
- iliocostalis
- longissimus
- spinalis

The erector spinae paraspinal musculature is stretched with flexion of the spine. A stretch of the bilateral erector spinae musculature is shown. To better stretch one side, opposite-side (contralateral) lateral flexion can be added.
