Upper and Lower Extremity Exercise and Exercise-Induced Hypoalgesia in Knee Osteoarthritis
Recruiting now · Not applicable
Conditions studied: Knee Osteoarthritis, Knee Pain Chronic, Central Pain Syndrome
In brief
The objective of the study is to explore the effects of arm exercise (UE, arm ergometer) vs. leg exercise (LE, cycling ergometer) on exercise-induced hypoalgesia (EIH), central pain mechanisms and knee pain in people with knee osteoarthritis (OA). Furthermore, we will explore relations of socioeconomic status, racial discrimination, acculturative stress, and autonomic function to exercise effects on EIH, central pain mechanisms, and knee pain. This will be a pilot randomized cross-over study where all participants undergo Day 1 (baseline assessments), Day 2 (UE or LE), and Day 3 (UE or LE).

You may qualify if…
- We will recruit participants with knee OA, using the National Institute for Health and Care Excellence's clinical diagnostic criteria, which does not require radiographs. The clinical diagnostic criteria include:
- age ≥45
- activity-related knee pain
- either no morning joint-related stiffness or stiffness that lasts ≤ 30 minutes.
- knee pain at least 4 on a 0-10 pain scale
- knee pain as a chief complaint if having multiple pain
- understand English
You may not qualify if…
- peripheral neuropathy or other sensation loss on the body sites for pain measurements (i.e., the wrist, knee, the forearm)
- use of medical devices electrically active (e.g., pacemaker)
- chronic use of opioids
- pregnant women
- serious and uncontrolled concomitant disease, including cardiovascular, nervous system, pulmonary, renal, hepatic, metabolic, hormonal, endocrine, gastrointestinal or epileptic disease
- rheumatoid arthritis, ankylosing spondylitis, and any neurological disorders that prevent the study procedure
- cognitive impairment
- history of a knee replacement surgery
- inability to perform exercise due to severe pain or other symptoms
- any intervention procedures for knee pain in the last 3 months
- Inclusion and exclusion criteria for pain-free controls (Target n = 20) Pain-free controls are not having a pain-related medical condition. They have to speak and understand English. Pain-free controls are excluded if they had experienced a pain episode, caused by musculoskeletal injury or otherwise in the previous 3 months.
