Abstract Author Manuscript

Objectives—To determine whether lower extremity sensorimotor peripheral nerve deficits are associated with reduced walking endurance in older adults. Design—Prospective cohort study with six years of follow-up. Setting—Two U.S. clinical sites in (Pittsburgh, PA and Memphis, TN). Participants—Community-dwelling older adults enrolled in Health, Aging and Body Composition study from the 2000/01 annual clinical examination (n=2393; age 76.5 ± 2.9 years; 48.2% male; 38.2% black) and subset with longitudinal data (n=1,178). Interventions—Not applicable

Main Outcome Measures—Participants underwent peripheral nerve function examination in 2000/01, including peroneal motor nerve conduction amplitude and velocity, vibration perception threshold, and monofilament testing. Symptoms of lower-extremity peripheral neuropathy included numbness or tingling and sudden stabbing, burning, pain, or aches in the feet or legs. The long distance corridor walk (LDCW; 400m) was administered in 2000/01 and every two years afterwards for 6 years to assess endurance walking performance over time. Results—In separate fully adjusted linear mixed models poor vibration threshold (>130 microns), 10-g and 1.4-g monofilament insensitivity were each associated with slower LDCW completion time (16.0, 14.1, and 6.7, seconds slower, respectively, P
