Phase 1: Randomized Evaluation of a System to Deliver Mobile Cognitive Behavioral Therapy

The clinical study described in this Clinical Investigation Plan (CIP) will be completed in two stages, Phase I and Phase II. The results of Phase I will confirm patient use of InCaveo\'s EOA system with integrated mobile CBT but without tapering to improve The Pain Catastrophizing Scale (PCS) scores, and secondarily scores on the VNS pain scale, the Tampa Scale of Kinesiophobia (TSK), and patient satisfaction scores in the subacute period (defined as 2 weeks to 3 months post TKR). Statistically significant positive results on the Pain Catastrophizing Scale (PCS) will trigger phase 2. Phase 1 will also inform the detailed conditions and patient management algorithms for Phase II.
