The effects of speed-dependent treadmill training and rhythmic auditory-cued overground walking on gait function and fall risk in individuals with idiopathic Parkinson's disease: a randomized controlled trial.

Objectives: The purpose of this randomized controlled study was to examine and compare the immediate and retention effects of speed-dependent treadmill training (SDTT) and rhythmic auditory-cued (RAC) overground walking on gait function and fall risk in individuals with Parkinson's disease (PD).

Methods: Twenty participants (mean age 66.1 yrs) with idiopathic PD were randomized into either SDTT (n = 10) or RAC (n = 10) progressive, interval-based locomotor training protocols.
