Exercise-induced Hypoalgesia and Proprioceptive Changes, Comparing Isometric to Isotonic Neck Exercises
University of South Dakota
Summary
Exercised induced hypoalgesia (EIH) (reduction in pain) after exercise has been studied in the literature, but no comparisons have been made specifically looking at different types of exercise (isometric/dynamic moving through a range of motion with resistance versus isotonic/applying static resistance to a joint not moving) with neck muscle strengthening. This study will explore to see if one form of exercise is superior to the other in providing EIH. Another benefit of exercise is improving proprioception (knowing where our body is in space). Again no specific investigation has been done comparing isometric versus isotonic exercises for neck muscles. Both of these exercises are often prescribed in physical therapy so further understanding the benefits of them can help improve the prescription of exercises for patients.
Description
After consent has been obtained, participants will be asked the screening questions to confirm eligibility for the study. The researcher will then ask the participants demographic questions and record the responses for age, gender, racial category, and handedness. Odd-numbered participants will perform isometric exercises first and then isotonic exercises on the second day. Even numbered participants will perform isotonic exercises first and then isometric exercises on the second day. There will be 2-3 days between each test period. Testing each time will have participants do baseline measurem…
