The Asymmetrical Overhead Squat: Choosing a Primary Driver
Priya, 34, runs about 25 km a week and reports a right knee that 'catches' on downhills. No pain at rest, no swelling, no injury history. Overhead squat: the right foot turns out roughly 10 degrees more than the left, the right knee drifts inward through the descent, and both arms fall forward near the bottom. Knee-to-wall ankle test in half-kneeling: right 8 cm, left 12 cm. Single-leg squat: the right knee tracks inside the second toe, the left is clean. Toe touch is unremarkable. Nothing she does reproduces pain, and she wants to keep running through the program.
1. Three impairments appear on the same side. How do you decide which one to attack first, and how would you verify that decision before committing six weeks to it?

Decision rule: treat the finding with a measurable left-right structural limit, not the most visually dramatic one.
- The only true asymmetry with a hard number attached is dorsiflexion (8 vs 12 cm). Foot turn-out and knee valgus are both closed-chain consequences of limited dorsiflexion - the foot abducts and the tibia internally rotates to buy range.
- The arms falling forward is real but belongs to a different chain (thoracic extension, lat, scapular upward rotation). It is not on the same line of pull as the knee, so it does not compete for priority.
Verify before committing:
- Elevate both heels ~2 cm on a board and re-screen the overhead squat. If turn-out and valgus visibly reduce, the ankle is the primary driver.
- Acute test: 60-90 seconds of calf SMR plus a 30-second static stretch, then re-measure knee-to-wall and re-squat.
If valgus persists with heels raised, move up the chain to gluteus medius and the adductor complex. Do not build a program that inhibits calves, adductors, and TFL simultaneously on day one - you lose the ability to tell what worked.
2. Priya's program is running well at week 4, but she asks whether she should stop running while you 'fix' the valgus. What is your answer and your reasoning?

Keep her running - the screen is a screen, not a diagnosis.
- She has no pain, no swelling, and no movement that reproduces symptoms. The 'catching' is a subjective report, not a finding that justifies unloading.
- Removing a 25 km/week habit to correct an asymptomatic alignment finding trades a known positive (aerobic base, adherence, mood) against an uncertain benefit.
- The rationale for unloading would be tissue irritation or symptom provocation. Neither exists here.
What you do instead: place the activation and integration work on non-running or easy days, keep static calf stretching after runs rather than before, and set a clear tripwire - if the catching becomes pain, or the knee swells, or she changes her stride to avoid it, running volume comes down and she gets referred. Write that tripwire into the plan so the decision isn't re-litigated every session.
