About this study
Official title: Predictive Value of the PBS-score - A Prospective Observational Cohort Study Evaluating Recurrence of Idiopathic Clubfoot and Need for Additional Treatment
Evaluate the predictive value of the PBS-score in predicting recurrence of idiopathic clubfoot, measured as need for additional treatment.
Read the detailed description
Using a consecutive inclusion, we aim to include 60 children and register data proposed by the COS for PEVA. All items of the PBS-score are video-documented, and dynamic foot pressure during walking is recorded during a clinical visit at the Motion Analysis Lab at Karolinska University Hospital. Children and caregivers will complete Roye's score, a disease-specific PROM and Oxford Foot and Ankle Questionaire-child (OxFAQc). For children aged 6 years or older, standing radiographic imaging of both feet will be performed. Inclusion criteria include: age 4-8 years, a diagnosis of idiopathic clubfoot, ability to walk 10 m repeatedly, and ability to communicate verbally (and in writing for caregivers) in Swedish or English. Included children will be followed prospectively during five years through clinical visits and medical records, where need for additional treatment (casting, braces and/or surgery) is the primary endpoint.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Systematic screeningOther
Also called PBS-score, video evaluation, PROM, dynamic foot pressure
Included children will be followed prospectively during five years through clinical visits and medical records, where need for additional treatment (casting, braces and/or surgery) is the primary endpoint.
What is being measured
The primary outcome is the main question the study is designed to answer.
Need for further treatment
total number of casting, type of braces and/or choice of orthopedic surgery
Measured: 5 years
Secondary outcomes (2)
Patient reported outcome measures (PROM)
Children and caregivers will complete Roye's score, a disease-specific PROM. The Roye´s score consists of 10 items designed to measure treatment outcomes regarding overall satisfaction, appearance, pain, and physical limitations.
Measured: 5 years
Patient reported outcome measures - The Oxford Ankle Foot Questionnaire for Children (OxAFQ-C) is a child - or parent (proxy)
Children and caregivers will complete The Oxford Foot and Ankle Questionaire-child (OxFAQc) and a proxy for caregivers measure subjective well-being in children affected by foot and ankle pain and function. The OxFAQc has 15 items. The response options to each item are on a 5-point scale rated from never (4), rarely (3), sometimes (2), very often (1) to always (0), where the number in brackets represents the value that should be applied by the scorer to each response. Domain scores are calculated as the total of the scale item scores divided by the maximum for each domain, physical 24, and school \& play and emotional 16). Domain scores can be transformed to a percentage scale (0-100) to aid interpretation. A higher score for a domain represents better functioning.
Measured: 5 years
