Summary
The Body Awareness Scale Movement Quality (BAS MQ) demonstrates good reliability and validity for assessing movement quality in patients with hip osteoarthritis. This tool effectively differentiates between healthy individuals and those with physical or psychiatric limitations.
Area of Science:
- Physiotherapy and Rehabilitation Science
- Movement Science
- Psychometric Evaluation
Background:
- Physiotherapy patients often present with limitations in daily movements, physical activities, or pain.
- The Body Awareness Scale Movement Quality (BAS MQ) assesses both functional limitations and resources related to movement quality.
Purpose of the Study:
- To investigate the psychometric properties of the BAS MQ, including its factor structure, validity, and reliability.
- To determine if the BAS MQ can differentiate between healthy individuals and patients with physical or psychiatric conditions.
Main Methods:
- Factor analysis was conducted on the BAS MQ for a total sample (n=172) including individuals with hip osteoarthritis (OA), psychiatric disorders, and healthy controls.
- Inter-rater reliability was assessed in individuals with hip OA (n=24).
- Concurrent validity was evaluated in individuals with hip OA (n=89) using the SF-36, 6MWT, and HOOS.
Main Results:
- Factor analysis revealed a three-factor structure explaining 60.8% of the variance in BAS MQ.
- Good inter-rater reliability (kappa=0.61) and acceptable validity were confirmed through significant correlations with SF-36, HOOS, and 6MWT in the hip OA group.
- The BAS MQ successfully discriminated between healthy individuals and those with physical and psychiatric limitations.
Conclusions:
- The BAS MQ exhibits a satisfactory factor structure, with acceptable inter-rater reliability and validity in individuals with hip osteoarthritis.
- The BAS MQ is a potentially valuable tool for physiotherapists in evaluating the quality of everyday movements across diverse patient populations.
