Introduction
Locomotive syndrome (LS) is a condition of reduced mobility. The LS stage can be determined by the stand-up test, two-step test, and 25-question geriatric locomotive function scale (GLFS-25). This study aimed to establish whether the LS stage can be reliably determined using the GLFS-25, and to clarify the correlation between the GLFS-25’s six subcategories and physical functions.
Materials and Methods
We administered the GLFS-25 and evaluated physical functions using the stand-up test, the two-step test, handgrip strength, the five-times sit-to-stand test, the 4 m walking test, and the duration of single leg standing. We assessed 103 participants over 65 years of age. We analyzed the correlation between LS stage and GLFS-25 score, as well as the correlations between physical functions and the GLFS-25’s six subcategories.
Results
There was a discrepancy between the LS stage determined using the GLFS-25 alone and the LS stage determined using all three tools. ROC analysis revealed a cut-off value of 6 for the discrimination of LS stages 0/1 and 14 for stages 1/2. The analysis revealed an AUC of 0.78 and 0.81, respectively. Among the six subcategories of the GLFS-25, movement-related difficulty, usual care, ADL, and social activities were correlated with mobility functions. In contrast, body pain and cognitive showed no correlation.
Conclusion
The GLFS-25 is useful for screening those with severe LS stages; however, evaluation of actual physical function is recommended for precise staging of LS in those with low GFLS-25 scores. Among the six subcategories of the GLFS-25, body pain and cognitive were independent of the other four subcategories.
