Muscle imbalance is one of the most common causes of back pain. One such imbalance that can be responsible for lower back pain and will primarily be associated with people who work in sedentary positions is often referred to as “forward-tilted pelvis.”
Continual and excessive sitting will tighten the hip flexors causing the abdominals, hamstring and buttock muscles to become weak.
The tight muscles pull the pelvis down and forward creating an excessive curve in the lower back causing the abdomen to protrude forward. The resulting pressure on the lower spine can eventually cause dysfunction and injury, such as sciatica, a herniated disc, or a muscle spasm and tightness.
