The Relationship between Components of Postural Control and Locomotive Syndrome in Older Adults.

Locomotive Syndrome (LS), a condition related to impaired mobility, is influenced by balance control, which comprises six components. Deficiencies in these components can lead to reduced mobility and decreased quality of life. This study aimed to evaluate the relationship between the components of postural control and LS in older adults using the Brief-BESTest. Therefore, this cross-sectional study involved 122 elderly participants from Tha Sala District, Nakhon Si Thammarat Province, both with and without LS. Participants underwent assessments using the Instrumental Activities of Daily Living (IADL) assessment, the Thai Mental State Examination (TMSE), the Two-Step Test, and the Brief-BESTest. The Brief-BESTest covers six balance components: Biomechanical Constraints, Stability Limits, Anticipatory Postural Adjustments, Postural Responses, Sensory Orientation, and Stability in Gait. Descriptive statistics were used to summarize participant characteristics, and Chi-square tests were conducted to examine the relationship between each balance component and LS. Cramer's V was used to assess the strength of the relationships. The results showed the average age of the sample was 67.67 ± 6.01 years with 85.20 percent female and 14.80 percent male. There were significant relationships between LS and three balance components: Biomechanical Constraints (Chi-square = 5.35,
