Purpose: To determine if balance or strength training improved fibular nerve conduction velocity, relative to a control group, in participants with chronic ankle instability (CAI).Methods: Thirty-seven participants completed baseline testing of motor nerve conduction velocity (m/s) of the fibular nerve. Participants were randomly assigned to one of three groups: balance training protocol (BTP), strength training protocol (STP), or sham control (CON). Each participant met three times per week for 6 weeks and completed his or her respective protocols.
