Mechanism for Right Side Lower Limb Symptoms

From early in my career I have frequently observed tightness and tenderness in the right QL's accompanied by tightness in the left glutes. It is a common pattern. Eventually I worked out the cause for thickening and tightening down the backline of the left lower limb...being anterior rotation of the hip about the SIJ >>> joint tightness blocking energy flow down the, with one exception, every left sided case of Plantar Fasciitis I have sighted is accompanied by anterior hip rotation and a common unforced football injury is a torn left hamstring and every second pro-tennis player has Rock Tape down the back of their left hami. The right QL condition remained a mystery until after a spate of cases brought it front and centre in my attention. Several had medical scans revealing right sided disk bulging. What all these cases had in common was a leg length discrepancy...the right leg shorter than the left. It then struck me the postural anomaly of a dropped right hip causing a right leaning scoliosis will open the lumber vertebrae on the right and the elevated left hip will close the lumbar vertebrae on the left. This accordion like action creates a wedge shape where the vertebral surfaces should be parallel and forces the disk out to the right. I am inclined to think this is a common cause for right sided lumbar disk bulges.

Effects on the back line of the lower limbs from Short Right Leg Syndrome (SRLS) are not known and poorly understood by the therapeutic community. Left leg cases due to the effect on the SIJ by the postural anomaly of anterior hip rotation. Right sided cases due to lumbro-sacral dysfunction caused by mild disk bulging through lumbar region and the Pendulum Effect on gait causing rigidity at right hip and adductors. Right sided cases are less common by a factor of ten. I consider them to be more serious as these symptoms indicate the integrity of the spine is being compromised. Right side symptoms may never amount to anything more than low level symptoms but under sustained pressure, loading or an event may result in catastrophic disk bulge. The right SIJ may elicit pain on palpation together with thickening and tightening down the backline of the right lower limb from glutes to plantar fascia.
