Why should the first row be above the islets?
less force placed on the foot at the level of toe break
Why should runners turn their socks inside out?
eliminate pressure points due to the seam
What type of orthotic would someone with a supinated foot need?

What type of orthosis is needed for pes planus?

What is the purpose of the Ottawa Ankle rules?
determine if radiographs are necessary
What are the Ottawa Ankle rules?
- Find out MOI and gauge pt’s ability to bear weight within the first hour of injury
- Begin palpation in neutral site (forefoot)
- Palpate for bone tenderness
- Posterior edge of malleoli
- 5th metatarsal (prox tip to base)
- navicular
- distal 6 cm of fibula
- When bone tenderness is absent, have the pt take 4 steps, 2 with each foot. If they can’t do it, refer for radiograph
- Have pt seek f/u care if pain doesn’t decrease and WB doesn’t increase after 5-7 days
What is the first line of defense to correct/resist abnormal mechanics during walking/running/activities?
proper footwear

- PF
- ITB syndrome
- tibial stress syndrome
- Morton’s neuroma
- metatarsalgia
Where do you look on a shoe to see the wear pattern?

How do you measure LLD in standing?
ASIS to medial malleolus

Is a LLD more impactful in the sedentary or active population?
- active
- performing more impact activities that are altered with LLD, whereas sedentary individuals don’t
