Pelvis is a big bowl shape structure supporting spine and organs inside. It is also a base of your spine.
If pelvis is uneven, spine naturally becomes not straight, leaning toward lower side of pelvis. Spine is also a base of head where your vestibular system sits within.
Since vestibular system wants to bring your head on the center of your body, leaned spine develops C sharped curve towards the other side.
In more complicated condition, it makes S- shaped curve. We call those curves as “Scoliosis”.
Initially, body compensates this unevenness well. However, if this pattern gets worse, body starts to make lots of issues.
Body weight is leaning on one leg and back more which can lead to one side back and disc problem, back muscle tightness (trigger points), and hip joint stiffness and pain.
In this circumstance, nervous system doesn’t function well either. Nerve roots coming out of spinal cord can be inhibited since nerve pathway is narrowed when spine is not straight.
Nerve is a wire sending the signal to each muscle and organ. Muscular system doesn’t work well if nerve conduction decreases. Posture muscles doesn’t coordinate well with each other, showing weak core strength and poor posture.
Organs innervated by parasympathetic nerves in abdomen doesn’t function well. It presents with low metabolism of your body with increased body fat especially in lower abdomen. It can also cause constipation, stomach, liver and even heart problem.
What can cause uneven pelvis?
1. Muscle imbalance around pelvis
Tight Hip flexor (iliopsoas) or Quadriceps(Rectus Femoris) muscles can make pelvis turning forward
Tight Abdominals (Rectus Abdominus) or Hamstring muscles can make pelvis turning backward
Tight Quadratus Lumborum muscle can pull your pelvis higher than the other side pelvis.
2. Uneven standing position
If you stand bearing your weight on one side leg more often than the other, hip joint slowly adapts to faulty position which can cause pelvis unevenness. Weight bearing side tends to get tighter and shorter than non-weight bearing side leg.
3. Sitting with one leg crossed over the other leg (One side preferably)
Crossed side causes hip joint to turn outward making the same side leg longer
4. Seating with crossed legs on the floor for a long time
It can make hip joint off aligned into the forward and outward rotated joint position
5. W-seating on the floor for a long time
It can make hip joint off aligned into the back and internal rotated joint position
6. Asymmetrical pattern in daily life
Long time habitual body pattern becomes being natural in your brain and it progressively builds up muscle imbalance and joint mal-alignment
