Conditions: Knee Osteoarthritis; Chronic Pain; Kinesiophobia

Summary: the goal of this clinical trial is to test using a pain and anxiety reduction phone application in older adults with knee osteoarthritis and chronic pain. the main questions it seeks to answer are: 1. how acceptable is using a phone app in older adults with knee osteoarthritis and chronic pain to lower pain, pain stress and reduce fear of movement? 2. what are the effects of combining biofeedback with a virtual reality nature scene and paced breath training to increase heart rate variability on pain and anxiety among older adults with knee osteoarthritis? 3. what is the role of self-regulation and body awareness in predicting or strengthening the effect of combining virtual reality, heart rate variability biofeedback in older adults with knee osteoarthritis?. participants will be asked to: 1. use a phone application for 7-10 minute sessions twice daily 5 days a week for 8 weeks. 2. receive relaxation reminders weeks 9 through 12 to see if use continues past the intervention phase. 3. complete surveys describing pain, physical activity, fear of movement, body awareness and self-regulation, pain stress pre/post the app use. 4. complete a survey and interview after 8 weeks of phone app use to describe the experience of its use.

purpose: this single-group pre-post intervention design, study will explore the feasibility of using a multicomponent phone-based app for 8 weeks to reduce pain, pain stress effects, decreased heart rate variability and fear of movement in 24 older adults with knee osteoarthritis and to examine sustained use and or effects at 4 weeks after intervention period. aim 1 evaluate the feasibility (adherence and satisfaction) of a multicomponent phone app combining virtual reality and heart rate variability biofeedback for use in older adults with knee osteoarthritis and chronic pain and gain descriptive evaluations of the experience in exit interviews. adherence: the adherence benchmark will be 80% of participants will participate at least 5 days per week during the initial 8-week intervention period. adherence will be examined (not benchmarked) during the 4-week follow-up period. satisfaction: exit interviews will demonstrate that 80% of participants practicing with the phone app rate the experience as satisfying or highly satisfying. aim 2 evaluate the preliminary effects of multicomponent phone app use (5 days a week for 8 weeks) in older adults with knee osteoarthritis, in relation to pain, pain stress effects, and fear of movement (kinesiophobia), and examine sustained use patterns and effects with only reminders from the app during the 4-week follow-up period. aim 3: examine the role of body awareness and self-regulation to moderate (predict) or mediate (strengthen) the effect of a virtual reality nature scene and heart rate variability biofeedback phone application in older adults with knee osteoarthritis.
