Abstract
Background: The purpose of this study was to examine whether impairments in sensorimotor peripheral nerve function are associated with a higher likelihood of swallowing impairment in older adults. Methods: Health, Aging and Body Composition participants (n=607, age=75.8±2.7 years, 55.8% women, 32.3% black) underwent peripheral nerve testing at Year 4 and 11 with swallowing difculty assessed at Year 4 and 15. Nerve conduction amplitude and velocity were measured at the peroneal motor nerve. Sens ...
Background: The purpose of this study was to examine whether impairments in sensorimotor peripheral nerve function are associated with a higher likelihood of swallowing impairment in older adults. Methods: Health, Aging and Body Composition participants (n=607, age=75.8±2.7 years, 55.8% women, 32.3% black) underwent peripheral nerve testing at Year 4 and 11 with swallowing difculty assessed at Year 4 and 15. Nerve conduction amplitude and velocity were measured at the peroneal motor nerve. Sensory nerve function was assessed with the vibration detection threshold and monoflament (1.4-g/10-g) testing at the big toe. Symptoms of lower extremity peripheral neuropathy and difculty swallowing were collected by self-report. Data analysis was performed using a hierarchical approach. Odds ratios (ORs) were estimated using non-conditional logistic regression. Results: At Year 15 108 (17.8%) participants had swallowing impairments. In fully adjusted models, the peripheral nerve impairments associated with swallowing impairment were numbness (OR 4.67; 95%CI 2.24–9.75) and poor motor nerve conduction velocity (OR 2.26; 95%CI 1.08–4.70). Other peripheral nerve impairments were not related to swallowing. Conclusions: The association between slow motor nerve conduction velocity and numbness and a higher likelihood of swal lowing difculties a decade later in our prospective study identifes an important area for further investigation in older adults. ...
