University of South Dakota52 enrolled

Overview

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.

Outcomes

Primary Outcomes

Straight leg raise Range of motion on dominate leg

Hamstring range of motion is measured with a standard goniometer on the dominant leg (the leg you would prefer to kick a ball with). Participant lying supine, the examiner assists with raising the leg straight (knee at 0 degrees extension) at the hip into flexion. Measure maximal hip flexion, with no change in knee extension, posterior pelvic tilt, or lumbar spine flexion. Goniometric measurements of hamstring length will then be measured with the stationary arm in line with the lateral midline of the pelvis, the axis of the goniometer will be placed on the greater trochanter of the hip, and the movement arm will be lined up with the midline of the lateral femur to the lateral epicondyle of the ipsilateral knee.

Time frame: from enrollment to the end of the session at 1 day

Pain pressure threshold of the hamstring muscle group

Use of a handheld algometer to assess pain pressure threshold. Application of pressure at the middle point of the hamstring on the dominant leg (the leg you would prefer to kick a ball with). The middle point is determined by the midway point measured from the ischial tuberosity and the knee joint line. Pressure is applied at a steady rate until the participant reports that the sensation of pressure changes from pressure to pain. Measurement in kg/cm2 will be recorded and the average of three measurements will be recorded.
