Objective: To evaluate relationships among locomotive syndrome (LS), daily physical activity (PA), physical function, and body composition measurements in elderly Japanese individuals.

Materials and Methods: This study included 39 elderly participants (mean age, 68.4±5.5 years). All participants completed three LS risk assessments, the two-step test, stand-up test, and 25-question geriatric locomotive function scale (GLFS). To assess LS, a stage 1 LS (LS-1) cutoff was applied. Physical function was assessed using the chair stand, sit-up, 10-meter (m) walking time, and 10-m zigzag walking time (ZWT) tests. Additionally, the isometric strength of the knee extensors and flexors were evaluated and body composition measurements were performed. Habitual daily PA (step count and intensity of PA) was evaluated using a three-axis, high-frequency wrist accelerometer.

Results: The proportion of LS-1 in this study population was 35.9% (14/39). The number of daily steps, 10-m walking time, 10-m ZWT, knee extension strength, and knee flexion strength were significantly higher among non-LS participants than among LS-1 participants. The 10-m walking time, 10-m ZWT, knee extension strength, and knee flexion strength were significantly higher and the chair stand score tended to be higher among non-LS participants than among LS-1 participants. For all participants, the stand-up test scores correlated with the 10-m walking times, 10-m ZWTs, chair stand scores, sit-up scores, and knee extension strength.

Conclusions: LS might be associated with daily PA, physical function, and isometric knee extension strength. Furthermore, the stand-up test is a good index for LS screening in elderly individuals.
