An instrument evaluation framework: description and application to assessments of hand function

Area of Science:

• Hand therapy
• Occupational therapy
• Rehabilitation science

Background:

• Selecting appropriate measurement instruments is crucial for effective hand therapy.
• Existing methods for instrument selection may lack comprehensive evaluation criteria.
• Standardized and validated assessments are needed to measure functional limitations accurately.

Purpose of the Study:

• To present a detailed framework for evaluating and selecting measurement instruments in hand therapy.
• To provide a structured approach for assessing instruments based on predefined criteria.
• To guide hand therapists in making informed decisions about assessment tools.

Main Methods:

• Development of a multi-section evaluation framework: clinical utility, standardization, purpose, psychometric properties, and patient's perspective.
• Application of the framework to four distinct hand function assessments: TEMPA, Jebsen Test of Hand Function, Smith Hand Function Test, and Quantitative Test of Upper Extremity Function.
• Comparative analysis of the selected instruments using the established framework criteria.

Main Results:

• The framework systematically evaluated four hand function assessment tools.
• The Test Evaluant les Membres Supèrieurs des Personnes Agèes (TEMPA) was identified as the most appropriate instrument for the therapists' specific setting.
• The framework facilitated a critical and comprehensive comparison of the instruments' suitability.

Conclusions:

• The proposed framework offers a robust methodology for selecting measurement instruments in hand therapy.
• Implementing this framework ensures a consistent and justified approach to instrument selection.
• The framework empowers therapists to optimize assessment practices and enhance patient care.
