Summary
The Movement System Screening Tool (MSST) effectively identifies athletes at risk for non-traumatic extremity injuries by assessing movement patterns. This validated screening tool demonstrates good reliability for clinical use in injury prevention.
Area of Science:
- Sports Medicine
- Biomechanics
- Musculoskeletal Health
Background:
- Non-traumatic extremity injuries are prevalent in athletes, causing significant burdens.
- Musculoskeletal risk factors include inefficient movement, instability, limited mobility, and asymmetry.
- The Movement System Screening Tool (MSST) was developed to assess these risk factors.
Purpose of the Study:
- To describe the development of the MSST.
- To determine the content and construct validity of the MSST.
- To establish the inter-rater reliability of the MSST.
Main Methods:
- Content validity was established by an expert Delphi panel.
- Construct validity was assessed using exploratory factor analysis and known group analysis in 80 athletes.
- Inter-rater reliability was determined by two independent raters.
Main Results:
- Exploratory factor analysis identified 3 of 4 constructs across 7 factors (14 tests), explaining 63% of variance.
- Athletes with shoulder injuries had significantly lower MSST composite scores (56.9±5.8) than uninjured athletes (62.7±4.5).
- Excellent inter-rater reliability for composite scores (ICC=0.94) and good item reliability (κ=.57-1.00) were found.
Conclusions:
- The MSST demonstrates construct validity and acceptable measurement properties for clinical application.
- The MSST can identify athletes at risk for injury.
- The tool can be used in studies validating interventions for movement impairment and injury risk.
