Summary
A new Multidimensional Nil Hallux Valgus (HV) Scale was developed to assess HV symptoms. This valid and reliable scale offers a comprehensive evaluation for healthcare professionals.
Area of Science:
- Orthopedics
- Podiatry
- Medical device development
Background:
- Hallux valgus (HV) is a common foot deformity.
- Existing assessment tools may not capture the full spectrum of HV impact.
- A need exists for a comprehensive, disease-specific measure of HV.
Purpose of the Study:
- To develop a novel, multidimensional scale for hallux valgus (HV).
- To establish the validity and reliability of the new HV assessment tool.
Main Methods:
- Developed the 14-item Multidimensional Nil Hallux Valgus Scale (score range 0-60).
- Included 129 feet from 66 patients diagnosed with HV.
- Assessed validity and reliability using AOFAS-MTF-IF, Manchester Scale, and SF-36.
Main Results:
- Factor analysis revealed 5 factors explaining 73.2% of variance.
- Scale demonstrated acceptable floor (3.1%) and ceiling (0.8%) effects.
- High internal consistency (Cronbach's alpha 83.3%) and test-retest reliability were observed.
Conclusions:
- The Multidimensional Nil Hallux Valgus Scale provides a holistic evaluation of HV.
- The scale is a valid and reliable instrument for clinical use.
- Facilitates convenient and comprehensive assessment by healthcare professionals.
