This protocol was a component of a clinical trial designed to evaluate an in-home self-management program for chronic lower limb swelling in people with limited mobility that utilized TR to provide real time face-to face interactive educational and assessment sessions over a six week period. Developed as a series of videos, the protocol was designed to encompass 10 learning goals for self-management of chronic swelling/lymphedema. Content validity was determined by eight certified lymphedema therapists. The mean score for the videos was 4.5 ± 0.35 (Likert scale of 5 = strongly agree to 1 = strongly disagree). The readability level of 5th grade and superior suitability rating using the Suitability Assessment of Materials indicated materials were appropriate for various levels of health literacy in the study population. TR-PUMPS was implemented utilizing the Versatile and Integrated System for Telerehabilitation (VISYTER) software platform, a secure system that provides the ability for real-time teleconferencing. Evaluation of the subjects’ post intervention Competency in Self Care and Self-Management (CSCSM) of their chronic swelling resulted in a mean score of 94% + 4%. Inter-rater reliability of the CSCSM was high. The Intraclass Correlation Coefficient (ICC) for iv single measures was .958 with a 95% confidence interval of .913 - .980 (p = .000). ICC of average measures was .979 with a 95% confidence interval of .955 - .990 (p = .000). Self- identified performance goals measured by the Canadian Occupation Performance Measurement showed significant improvement post intervention (p = .008) and exceeded the minimal importance difference. There was no significant change in the subjects’ self-efficacy in management of their chronic swelling scores (p = .065). The subjects’ perceived usability of the remote delivery of TR-PUMPS was high with a mean score of 6.4 + 0.65 (Likert scale of 1 = disagree to 7 = agree). These results support TR-PUMPS as a viable method for providing a home-based self-management program for chronic swelling. v TABLE OF CONTENTS PREFACE .................................................................................................................................
