Aging and Chronic Knee Pain

Aging and Chronic Knee Pain

This research is being done in order to broaden our understanding of how pain mechanisms differ between older adults with chronic knee pain and pain-free older adults. Additionally, we hope to observe differences between how different muscles are activated during a knee extension in a group of older adults experiencing knee pain versus pain free (no knee pain) older adult group. We will compare these findings to a group of young adults to help determine the effect that aging has on both pain mechanisms as well as muscle activation.

We expect that you will be in this research study for approximately 1-2 weeks. You will be asked to come into the UCF CNS laboratory for 3 visits: one familiarization visit and two testing visits. Each visit will last at maximum 90 minutes. During the familiarization visit you will fill out some paperwork to learn about the upcoming protocols, conduct some baseline demographic measures, and then we will get you comfortable with the testing procedures. During one of the testing sessions, you will undergo a protocol for testing pain modulation. During the second testing session, you will be performing maximal voluntary contractions of the knee for muscle analysis.

Inclusion Qualifications:

  • Healthy adult between the ages of 18-25 years with no knee pain.
  • Healthy adult at least 50 years of age with no knee pain.
  • Healthy adult at least 50 years of age with knee pain.
