Foam rolling (FR) is a common tool and procedure used in rehabilitation. Previous research has demonstrated physical improvements in range of motion and subjective reductions in pain post-intervention. Most of the literature theorizes potential biophysical reasons for these changes, but definitive studies are lacking. Another potential mechanism for these improvements may be psychological. The purpose of this study is to explore the psychological changes that occur in response to the instructions given to the patient and how these may influence the outcomes the individual receives while undergoing FR. Different instructions will be given for the same technique of FR to see if there are differences in changes with pain and range of motion.
Participants will receive one set of instructions that highlights the pain relieving properties of FR, while the other group will receive instructions on ability of FR to improve range of motion. Participants will be measured for range of motion and pain changes in both groups pre and post instruction and performing the identical technique of FR.
