Background and Aims: Based on the kinesiopathological model, certain corrective strategies mentioning the underlying altered movement and postural patterns, may prevent the onset of musculoskeletal pains. Before planning any measure, the specialists need an accurate identification of movement and postural impairments that have predisposed the individual to a specific musculoskeletal pain. There are conflicting results regarding the effectiveness of a specific corrective exercise intervention in LBP prevention. This inconsistency might be due to the use of heterogeneous groups of subjects in this study. Therefore, classification seems necessary in this regard. One of the suggested classification systems which is practical in both treatment and preventive measures is Movement System Impairment (MSI) model. No previous study has been conducted to validate the proposed system for preventive measures. The aim of this study was to assess the construct validity of the MSI classification system in females susceptible to LBP.
Materials and Methods: 250 females aged between 18-75, who developed transient low back pain greater than 10 VAS during 30-min. prolonged standing, were examined by 2 corrective exercise specialists. A Principal Component Analysis (PCA) was used to derive proposed categories. Factor loadings in the component matrix were assessed to identify the factor characterizing each component. The 5 configured components were compared with 5 MSI proposed categories.
Results: The five extracted components from PCA, explaining 87% of the total cumulative variance, were equivalent to 5 MSI proposed categories. The five derived components represented: Extension-Rotation, Flexion-Rotation, Flexion, Rotation, and Extension-Rotation categories, respectively.
Conclusion: Identification of the 5 proposed categories, confirms the validity of MSI test items as a classification tool for preventive measures related to low back pain in females. Specialists can use this model for identification of susceptible females' movement and postural impairments and take a positive step towards preventing low back pain by modifying these impairments before the onset of pain.
