Pronation
Pronunciation: pro-NAY-shun
The inward rotation of the foot; in the foot, the combined movement of eversion, abduction, and dorsiflexion of the subtalar joint, commonly referred to as 'flat foot' when excessive.
Full Definition
Pronation is the normal triplanar motion of the subtalar joint that allows the foot to adapt to uneven ground and absorb shock during gait. Excessive or prolonged pronation (overpronation) is one of the most common biomechanical findings in orthotic practice and is associated with conditions such as plantar fasciitis, shin splints, and knee pain. Orthoses for overpronation typically include medial heel wedges or longitudinal arch support. Editors should note that 'pronation' is frequently misspelled as 'pronate' (the verb) or confused with 'supination'. The distinction between physiological and pathological pronation is clinically significant and should be preserved in documents.
Usage
Usage note: Distinguish between normal pronation (a necessary part of gait) and overpronation (a pathological excess). Do not use 'eversion' as a full synonym.
