Kamitami et al, studied the spinal posture in 804 participants (65–94 yrs of age) who were initially independent in their activities of daily living (ADLL) at baseline. These participants were followed for a 4.5-year follow-up period and it was found that 126 (15.7%) of the participants became dependent in their ADLs. Dependence in ADL was defined as admission to a nursing home or need of home assistance to perform basic self care functions. Importantly, inclination of the upper body relative to the pelvis (angle subtended between the vertical and a line joining C7 to the sacrum) was correlated with outcome and lumbar curvature also showed a marginal association.

Indicating that the highest quartile had a relative risk of approximately 1.79 x 3 = 5.37 times more likely to be dependent. This study identifies that maintaining a close to vertical sagittal posture of the thorax over the pelvis is important for the elderly person wanting to remain able to perform basic care functions.

Accumulated evidence shows how important spinal posture is for aged populations in maintaining independence in everyday life. However, the cross-sectional designs of most previous studies prevent elucidation of the relationship between spinal posture and future dependence in activities of daily living (ADL). We tried to clarify the association by measuring spinal posture noninvasively in a community-based prospective cohort study of older adults, paying particular attention to thoracic curvature, lumbar curvature, sacral hip angle, and inclination to determine which parameter is most strongly associated with dependence in ADL.
Spinal posture was evaluated in 804 participants (338 men, 466 women, age range: 65-94 years) who were independent in ADL at baseline. We defined dependence in ADL as admission to a nursing home or need of home assistance. During the 4.5-year follow-up period, 126 (15.7%) participants became dependent in ADL. The relationship between the spinal posture parameters and outcome was assessed by dividing the participants into sex-specific quartiles of the parameters.
Only inclination (angle subtended between the vertical and a line joining C7 to the sacrum) was associated with outcome, although lumbar curvature also showed a marginal association. The age- and sex-adjusted odds ratio for a 1 unit increase in the quartiles of inclination was 1.79 (confidence interval: 1.44, 2.23). After mutual adjustment for the 4 parameters, statistical significance for inclination still remained, with no substantial changes in the association estimates.
This study indicates that spinal inclination is associated with future dependence in ADL among older adults.
