Causes
ITBS can result from one or more of the following training habits, anatomical abnormalities, or muscular imbalances:
Training habits:
- Always running on a banked surface (such as the shoulder of a road or an indoor track) bends the downhill leg slightly inward and causes extreme stretching of the band against the femur
- Inadequate warm-up or cool-down
- Excessive up-hill and down-hill running
- In cycling, having the feet "toed-in" to an excessive angle
- Running up and down stairs
- Hiking long distances
- Rowing
- Breaststroke
Abnormalities in leg/feet anatomy:
- High or low arches
- Supination of the foot
- Excessive lower leg rotation due to over-pronation
- The force at the knee when the foot strikes
- Uneven leg length
- Bowlegs or tightness about the iliotibial band.
- Excessive wear on the outside heel edge of a running shoe (compared to the inside) is one common indicator of bowleggedness for runners.
Muscle imbalance:
- Weak hip abductor muscles
- Weak/non-firing multifidus muscle
