Summary
This study established normative data for the Dutch Short Musculoskeletal Function Assessment (SMFA-NL). Results show significant differences in function and bother indices between genders and age groups, aiding in benchmarking musculoskeletal health.
Area of Science:
- Orthopedics
- Rehabilitation Medicine
- Public Health
Background:
- The Short Musculoskeletal Function Assessment (SMFA) is a widely utilized tool in musculoskeletal research and clinical settings.
- Limited normative data for the SMFA hinders precise interpretation of patient scores.
- Establishing normative data for the Dutch population (SMFA-NL) is crucial for accurate health status assessment.
Purpose of the Study:
- To collect and analyze normative data for the Dutch version of the Short Musculoskeletal Function Assessment (SMFA-NL).
- To identify age and gender-specific differences in SMFA-NL scores within the Dutch population.
Main Methods:
- The SMFA-NL, comprising function and bother indices and four subscales, was administered to 900 patients across six age groups.
- Statistical analyses including ANOVA, t-tests, and regression were employed to evaluate age and gender effects.
- A high response rate of 97% ensured robust data collection.
Main Results:
- Significant gender differences were observed across most SMFA-NL indices and subscales (p < 0.001 to p = 0.002), except for upper extremity dysfunction.
- A notable gender-age interaction effect was found for upper extremity dysfunction, with women showing a steeper decline in scores with age.
- Significant age-related differences were evident in the bother index and lower extremity dysfunction and daily activities subscales.
Conclusions:
- The study successfully generated normative data for the SMFA-NL, revealing significant variations based on gender and age.
- These findings underscore the importance of considering age and gender when interpreting SMFA-NL results.
- The established SMFA-NL normative data facilitate benchmarking the health status of individuals with musculoskeletal conditions against their age- and gender-matched peers in the Netherlands.
