Research Summary by Louis Ellery

Limited Hip Internal Rotation & Injury Risk

Association with low back & lower limb injury risk

Key Findings

Foot Structure & Back Pain

Individuals with flat feet or excessive foot pronation showed significantly elevated risk for low back pain compared to those with normal foot arch structure. Over 100,000 participants were studied.

Hip & Knee Alignment

The research identified moderate-to-limited evidence linking increased hip internal rotation and knee internal rotation with low back pain development.

Dynamic Over Static

Many studies examined alignment during walking and stance activities, emphasising that dynamic movement patterns — not just static posture — meaningfully correlate with back problems.

What This Means

These findings support a kinetic chain perspective: misalignment propagating from lower extremities (ankle to knee to hip to pelvis to spine) contributes to spinal stress and pain. This challenges isolated spine-focused treatment.
