NCT02508233 | Completed

• 1 other identifier: 09-130
• Study Type: observational
• Target: 34
• Locations: 0 countries
• Sites: N/A

Brief Summary

Many recent randomised multi-centre trials have used the AOS and the involvement of the French-speaking population is limited by the absence of a French version. The goal of our study was to develop a French version and validate the psychometric properties to assure equivalence to the English original.

Conditions

Ankle Osteoarthritis

Outcome Measures

Primary Outcomes (3)

• Reliability

  test-retest of AOS-Fr

  1 week

• Criterion validity

  Correlation of AOS-Fr and SF-36 and WOMAC scores

  1 day

• Construct validity

  Correlation of AOS-Fr and single heel-lift

  1 day

Study Arms (2)

Control

Healthy subjects (without ankle osteoarthritis) for validation of translation

ankle OA

Ankle osteoarthritis patients to ensure validity of translated scale

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

The "Test of the Pre-final version" will be performed using subjects with no ankle osteoarthritis who will answer the questionnaire and evaluate their comprehension of each item. Patients with isolated ankle degenerative changes at the orthopaedic outpatient clinic of the Centre Hospitalier Universitaire de Sherbrooke (CHUS) will be used to validate the questionnaire. Patients have to consider French as their mother tongue and be able to read and write in French. Patients under 18 years old and those with additional foot and/or ankle pathologies will be excluded.

You may qualify if:

• years of age and over
• French as their mother tongue
• able to read and write in French

You may not qualify if:

• foot and/or ankle pathologies
• OA group
• years of age and over
• isolated ankle degenerative changes
• French as their mother tongue
• able to read and write in French
• additional foot and/or ankle pathologies
