Abstract

Background. Poor peripheral nerve function is common in older adults and may be a risk factor for strength decline, although this has not been assessed longitudinally. Methods. We assessed whether sensorimotor peripheral nerve function predicts strength longitudinally in 1,830 par-ticipants (age = 76.3 ± 2.8, body mass index = 27.2 ± 4.6 kg/m2, strength = 96.3 ± 34.7 Nm, 51.0 % female, 34.8 % black) from the Health ABC study. Isokinetic quadriceps strength was measured semiannually over 6 years. Peroneal motor nerve conduction amplitude and velocity were recorded. Sensory nerve function was assessed with 10-g and 1.4-g mono-
