Relationship between plantar pressure and perceived quality of life in clubfoot J. Stebbins, J. Bates, J. McCahill, T. Theologis From the Nuffield Orthopaedic Centre, Oxford, UK
BACKGROUND
RESULTS OBJECTIVE
• Recent improvements in management of clubfoot deformity
• Even with optimal, early intervention
Assess the relationship between plantar pressure combined with motion capture and perceived quality of life in clubfoot
– Residual deformity – Recurrent deformity
peak pressure
Little correlation between physical deformity (OFM) and perceived quality of life • Degree of deformity may not be the best indicator for treatment?
• “Physical” and “School & Play” higher
•
Peak pressure in the forefoot region shows high correlation with quality of life
METHODS
• Significant impact on quality of life
•10 children (4-16 years) with clubfoot deformity
• Unclear relationship between:
•Oxford Ankle Foot Questionnaire
– When and how do you treat clubfoot deformity in the
•
• May be a better indicator for treatment in symptomatic older children
– Unexplained symptoms
– Perceived quality of life
• Generally higher correlation with forefoot

– Over correction

CONCLUSIONS
• Previous Work • Physical deformity
•Combination of plantar pressure and motion capture of the foot shows promise
– Oxford Foot Model
for determining impact of clubfoot deformity on quality of life
– Static and Dynamic
•Potential to use this to help guide treatment
– Foot Deformity Score
•Future work:
• Perceived quality of life – Oxford Ankle Foot Questionnaire – Disability associated with foot deformity
Previous work has shown little relation between foot dynamic motion and quality of life
•Include more subjects •Investigate better methods of combining motion capture and pressure data
