Learning Objectives At the end of the presentation on foot evaluation, participants will be able to: Describe constructs for core sets for foot pain Review assessment instruments for foot pain Reflect on quality metrics for foot pain
Plantar Fasciopathy Plantar fasciopathy is a painful condition of the foot caused by inflammation (which produces acute symptoms) or degeneration (a source of chronic pain) of the plantar fascia, which is the thick connective tissue extending from the calcaneus to the metatarsal heads. Function: static-supports arch Dynamic-medial arch flattens/ elevates

Windlass Test NON-WEIGHT BEARING With the patient sitting, the examiner stabilizes the ankle joint in neutral with 1 hand placed just behind the first metatarsal head. The examiner then extends the first metatarsophalangeal joint, while allowing the interphalangeal joint to flex. Passive extension (i.e., dorsiflexion) of the first metatarsophalangeal joint is continued to its end of range or until the patient’s pain is reproduced Weight Bearing The patient stands on a step stool and positions the metatarsal heads of the foot to be tested just over the edge of the step. The subject is instructed to place equal weight on both feet. The examiner then passively extends the first metatarsophalangeal joint while allowing the interphalangeal joint to flex. Passive extension (i.e., dorsiflexion) of the first metatarsophalangeal joint is continued to its end of range or until the patient’s pain is reproduced.
Active and Passive Dorsiflexion Description The patient is positioned in prone with feet over the edge of the treatment table. The examiner asks the patient to dorsiflex the ankle for an active measurement, or the examiner passively dorsiflexes the ankle, while ensuring that the foot does not evert or invert during the dorsiflexion maneuver. At the end of the active or passive dorsiflexion range of motion, the examiner aligns the stationary arm of the goniometer along the shaft of the fibula and aligns the moving arm of the goniometer along the shaft of the 5th metatarsal Diagram
Longitudinal Arch Test Description With the patient standing with equal weight on both feet, the midpoint of the medial malleolus, the navicular tuberosity, and the most medial prominence of the first metatarsal head are identified using palpation and marked with a pen. A goniometer is then used to measure the angle formed by the 3 points with the navicular tuberosity acting as the axis point. Measurement
Current Treatment Guidelines Heel Pain-Plantar Fasciitis Guidelines link International Classification of Functioning, Disability, and Health (ICF) body structures (ligaments, fascia of ankle and foot, neural structures of lower leg) and ICF body functions (pain in lower limb, radiating pain in a segment or region) with World Health Organization's International Statistical Classification of Diseases and Related Health Problems (ICD) health condition (plantar fascia fibromatosis/plantar fasciitis). Guidelines describe evidence-based physical therapy practice and provide recommendations for (1) examination and diagnostic classification based on body functions / structures, activity limitations, and participation restrictions, (2) prognosis, (3) interventions and (4) assessment of outcome, musculoskeletal disorders.

Assessment Measures for Activity/Participation The Foot Function Index (FFI) is a 0-10 scale of pain and foot function over time in standing, walking, etc. The Foot Health Status Questionnaire (FHSQ) is a 42-item questionnaire assessing quality of foot health. The Foot and Ankle Ability Measure (FAAM) is an activities-of-daily-living scale of foot health.
