Biomechanics and running gait analysis

A useful assessment combines your history, physical examination and observation of running. Video, motion sensors or force-measuring equipment may add detail, but a single movement pattern does not by itself diagnose an injury or prove its cause.

The clinician may compare cadence, stride, foot contact, trunk position, pelvic control and the alignment of the hip, knee and ankle. They may also observe how movement changes with speed, fatigue, footwear or an incline. Pressure equipment can show where and when force passes through the foot, while motion capture can track joint movement.

Results are interpreted in context. Asymmetry can be harmless, and textbook-looking form can still accompany pain. The most useful findings are repeatable, match the clinical examination and lead to a practical trial such as strength work, load adjustment, a cue or a footwear change.

Bring the shoes you normally run in, comfortable clothing, and any training notes that show when discomfort begins. Explain recent changes in distance, pace, surface, recovery, strength training and footwear. Mention previous injuries even if they are currently quiet.

Agree on the question before testing: reducing pain, returning after injury, improving tolerance or checking an orthotic. Ask to see the relevant footage and request a small set of measurable actions. A planned reassessment can show whether the change helps symptoms and function rather than merely altering appearance.

Stop running and arrange clinical assessment when pain changes your gait, persists at rest, repeatedly worsens with training, or is accompanied by focal bone tenderness, marked swelling, weakness or numbness. Sudden inability to bear weight, a visibly deformed joint, a cold or pale foot, or severe pain after trauma needs urgent care.

Gait testing should not delay evaluation of a possible fracture, acute tendon rupture or nerve problem. A clinician can first decide whether examination or imaging is needed and when running assessment is safe to resume.

Ask who interprets the test, whether the assessment includes a physical examination, which running speeds will be observed and how recommendations will be checked. If orthotics are proposed, clarify which finding they address and whether a temporary trial is possible before a longer-term device is made.
