Case of the Week: Rib Pain while Running: Part 2
Welcome back. Glad you picked choice d (or maybe you had a pint anyway)
Assessment: This patient has a significant difference in the length of her legs; her left leg being short, right leg being longer. The right ilia is rotated posteriorly (thus the tissue fold) in an attempt to shorten the extremity and the left ilia is rotated anteriorly, in an attempt to lengthen the leg. This is putting the abdominal external obliques in a lengthened and shortened position, respectively. The right is short weak and the left is long (stretch). The obliques attach to the lower ribs 5-12 (for external) and ribs 10-12 (for the internals).
The psoas muscle takes its origin form the lumbar vertebral bodies and inserts on the lesser trochanter of the femur. Due to the poterior rotation of the right ilia, it has been lengthened over time (thus the difference in hip extension) and is stretch weak on the right.
So why only on the right and during running?
due to the anatomical leg length difference, the right oblique has shortened over time. Running (forced inspiration and expiration) causes us to use some of our accessory muscles of respiration (obliques, intercostals, serratus posterior superior and inferior, sternocleidomastoid, scalenes. Remember that for quiet respiration, only the diaphragm is used for inspiration; passive tension in muscles for expiration).
Also, the stride length will be increased on the longer leg side (ie when the L leg is in swing and R in stance); this put additional stretch on the R iliopsoas and R abdominal obliques.
Treatment Plan: We placed a 3 mm lift in her left shoe. We treated with manipulative therapy of the lumbar spine. She was given the nontripod, side bridge, cross/crawl quadruped and hip flexor stretch with side bending exercises to perform on a daily basis. She felt better post treatment.
