Interventions

  • Exercise — PROCEDURE
    Neck exercises in a cross over design that the participants will do both types of interventions with a washout period inbetween.

Study Details

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.

Arms

  • Active Comparator: Isometric Exercise
    Isometric test protocol. Participants will be asked to perform the exercise at a moderate exercise level (3/10 on the mRPE scale provided to them). They will complete a 1, 10-second isometric hold to their hand dominant side (if ambidextrous, the side the participant would report as the most dominant side) to allow them to find their "moderate" intensity level. The participant will then take a 2-minute rest before beginning the exercise routine and will be instructed to keep a consistent resistance level during the exercise bout. During the exercise, the subjects will hold the rotation contraction for 10 seconds, take a 2-second rest, complete this 5 times, and then change to the left side. They will do this for 3 sets of right and left. Researchers will time the exercises and give verbal instructions to make sure they are performing for the appropriate amount of time and rest periods.
  • Active Comparator: Isotonic Exercise
    The resistance level will stay at the participant's selected moderate level during the entire testing unless they need to stop due to pain or difficulty completing the exercise. During the exercise, the participants will be rotating to the right first at a pace of 1 second for concentric contraction to full rotation and 1 second for eccentric contraction, returning the head to the neutral position. The participant will continue this pace to complete 5 repetitions and then take a 2-second rest before continuing this sequence 5 times (a total of 25 reps) before switching and doing left rotation in the same fashion. This will be done for a total of 3 sets for both right and left rotation. The use of a metronome will be used along with the researcher's verbal instructions and cueing to maintain the proper sequence and timing of the exercise.
