Use of a Self-Guided Mindfulness Mobile Application to Improve Pain Outcomes in Individuals With Knee Osteoarthritis

Use of a Self-Guided Mindfulness Mobile Application to Improve Pain Outcomes in Individuals With Knee Osteoarthritis

This study will investigate if mindfulness training via a smartphone mobile app is effective in improving OA-related knee pain.

The investigator's primary aim in this study is to determine if regular use of a mindfulness application improves pain outcomes in adults with knee osteoarthritis. The investigator's secondary aim is to determine if self-reported Healthcare-Related Quality of Life (HRQoL) scores predict response to mindfulness treatment in OA. The investigators hypothesize that the use of an mHealth intervention for mindfulness training may be an effective adjunct treatment of chronic knee osteoarthritis pain; specifically, that regular use of a mindfulness application will result in a statistically significant reduction in pain outcomes and improvement in physical function as determined by the KOOS scoring system. The investigators also hypothesize that those with lower baseline self-reported HRQoL scores are more likely to see a greater improvement in their pain and function with use of a mindfulness application than those with higher baseline scores.
