Movement-Evoked Pain and Tissue Irritability in Individuals with Shoulder Pain

The primary purpose of this research study is to examine pain during movement in individuals with shoulder pain based on muscle tissue irritability levels. Tissue Irritability is a clinical characteristic of musculoskeletal pain that is a composite definition of pain intensity and changes in pain during movement.

During one testing session that lasts about 2 hours, you will complete a few simple movements of your shoulder. You will be briefly exposed to heat, cold, and pressure to examine your pain sensitivity and complete questionnaires that characterize your thoughts and feelings about pain.

Inclusion Qualifications:

  • 18-75 years old
  • Experiencing shoulder pain that is at least 3/10 pain intensity (0=no pain, 10=worst pain imaginable) within the past 24 hours

Exclusion Qualifications:

You may not participate in this research opportunity if any of the following applies to you:
  • Medical conditions that affect sensation, such as uncontrolled diabetes
  • History of shoulder surgery or fracture within the past 6 months
  • History of a chronic pain condition, such as fibromyalgia
  • Current medical diagnosis of a myelopathy (compression of the spinal cord)
  • Any blood clotting disorders, such as hemophilia
  • Any condition that would prevent you from direct exposure to ice or icy water, such as:
    • uncontrolled hypertension (blood pressure over 140/90 mmHg)
    • Cold urticaria (develop hives when exposed to cold)
    • Cryoglobulinemia (condition in which you have abnormal protein in the blood causing the blood to become thick when exposed to cold)
    • Paroxysmal cold hemoglobinuria (autoimmune condition causing the destruction of blood cells after cold exposure)
    • Circulatory compromise (blood that does not flow to your arms and legs correctly)
  • Currently pregnant
