In new research doctors examined patients with knee osteoarthritis who are at risk of suffering sensations of instability, and experience buckling. The instability has been associated with psychosocial dysfunction, such as fear of movement, and impaired physical functioning. A high degree of fear of movement is positive correlated with avoidance in other conditions.
What they found suggests that pain catastrophizing and fear-avoidance beliefs are related with postural stability inpatients with knee and hip osteoarthritis. In addition postural stability is negatively correlated with pain catastrophizing and score assement activity avoidance. Thus, based on these results, psychosocial factors should be taken into consideration in the assessment and treatment of patients with hip and knee osteoarthritis.
Anxiety is a common byproduct of chronic pain and new research is suggesting that patients coping with chronic pain should be evaluated for anxiety disorders. In regard to back pain this subject is covered at length in Treating chronic back pain is an anxiety treatment for some and in Waiting for Knee Replacement Concerns
