Effects of Music During Walking on Pain and Muscle Activation in People With Chronic Pain Due to Knee Osteoarthritis

The purpose of this research study is to compare muscle activation, changes in pain sensitivity, and brain function, between different walking conditions, including walking to music, walking to metronome, and walking without music or metronome.
