Understanding the compression tradeoff
Greater Trochanteric Pain Syndrome: A presentation of symptoms characterized by lateral hip pain around the greater trochanter of the femur.
In short: Pain on the side of the hip
This hip pain is caused by irritation and degeneration of the tissues near the greater trochanter. These tissues include gluteal tendons and/or trochanteric bursa.
These tissues are irritated when the Tensor fascia latae (TFL) muscle and Iliotibial band (ITB) complex undergo tension resulting in compression of the underlying tissues against the greater trochanter.
Many clinicians assume that prescribing stretches will result in decreased TFL-ITB tension and overall less degeneration and pain.
This is only half-true, this perspective overlooks the potential harms of stretching.
After a stretch, the improved muscle extensibility and joint ROM can result in:
During the stretch, tension on the TFL-ITB increases and can cause:
Deciding whether to stretch TFL-ITB will come down to a simple tradeoff:
Does stretching cause more or less net compression?
Choose the option that results in the least net compression
The long term decreases in compression from stretching must outweigh the short term increases in compression during the stretch exercise.
In the clinic, look for a direct relationship where a limited TFL-ITB complex results in dysfunctional movement patterns.
Perform a movement analysis and look for limitations in hip extension and adduction during:
Patients who can perform these activities correctly without experiencing TFL-ITB tightness are less likely to benefit from stretching.
Patients who experience TFL-ITB tightness and exhibit movement compensations would benefit most from stretching.
