Objectives
We sought to assess associations of postural tremor with gait and balance impairments among community‐dwelling older people in both cross‐sectional and longitudinal analyses.
Design
A prospective cohort study.
Setting
Communities in Beijing, China.
Participants
This study included 7075 individuals aged 55 years or older.
Measurements
Postural tremor was assessed using a two‐step method (tremor screening followed by a confirmation examination of positive cases) at baseline. Gait and balance performances were measured with the Tinetti Mobility Test at baseline and 1 year later.
Results
At baseline, 45 (24.7%) of 182 tremor cases vs 663 (9.6%) of 6893 controls had gait and balance impairments. At 1‐year follow‐up, 19 (21.1%) of 90 tremor cases vs 416 (9.8%) of 4262 controls experienced a rapid decline in gait and balance performance. After controlling for potential confounders, postural tremor was associated with gait and balance impairments at baseline (odds ratio [OR] = 1.77; 95% confidence interval [CI] = 1.20‐2.62; p = .004) and a rapid decline in gait and balance performance at 1‐year follow‐up (OR = 1.99; 95% CI = 1.17‐3.39; p = .01).
Conclusion
In this population‐based cohort study, we found postural tremor was associated with gait and balance impairments among community‐dwelling older people in both cross‐sectional and longitudinal analyses. Our findings suggest that motor function should be routinely evaluated and monitored in older people with postural tremor.
