Biomechanics is the study of how the body moves. In the foot and ankle, small differences in alignment and motion can change how force travels through every step, and that can show up as pain in the heel, arch, big toe, shin or even the knee.
What gets looked at
- Arch shape, from very flat to very high
- Ankle and calf flexibility
- Foot, knee and hip alignment
- How you stand, walk and, if relevant, run
- Footwear and how it wears
- Training volume and recent changes in activity
Why it matters
Treating only the painful spot can bring temporary relief while the underlying cause keeps overloading the same tissue. For example, a tight calf can increase strain on the heel and the front of the foot, and an unstable arch can contribute to bunion progression or tendon irritation.
How the findings are used
Depending on what is found, the plan may include stretching and strengthening, changes to footwear or training, orthotics, or bracing. When a structural problem is driving symptoms and non-surgical care is not enough, understanding the mechanics also helps in planning surgery, so the operation addresses the cause as well as the symptom.
If pain keeps returning in the same place, or shifts from one area to another, a biomechanical evaluation may help explain why.
