Clinical Trial Summary

In this project, a web-based exercise program is developed in co-creation between specialized health care, the Norwegian Association for Rheumatic diseases (NRF) and a group of experienced patient representatives. The project emerges from the evidence that exercise is recommended as first-line treatment for patients with chronic diseases like hip- and knee-osteoarthritis (OA). However, the number of patients in need of targeted exercise will increase considerably the next decades, and their treatment needs cannot be fully handled within the health care system. Development of innovative and effective treatment trajectories and follow-up strategies is urgently required. Peer-support is recognized as an effective way to increase patients' long-term adherence to exercise. Thus, patient-organizations may be an unutilized resource in support and follow-up of patients who need long-term exercise as part of their treatment plan. After discharge from examination in hospital, patients with hip/knee OA will be recruited to follow-up in a novel web-based, peer-supported exercise program, and the feasibility of the intervention will be evaluated.

Description:

The study will be conducted as a pre-post single-arm feasibility study comprising 50 participants.

The main objective of the study will be to evaluate the feasibility of the web-based, peer-supported exercise intervention in patients with hip and/or knee OA.

Specific research objectives are:

• to assess feasibility of intervention delivery, data collection, eligibility and inclusion/exclusion criteria and intervention fidelity

• to assess the responsiveness of relevant primary and secondary outcome measures

In the feasibility study, all participants will be allocated to an intervention group, receiving a 12-week web-based, peer-supported aerobic exercise program including weekly motivational messages. Patients between 40 and 80 years of age that are not candidates for surgery will be recruited from Diakonhjemmet Hospital, Oslo, Norway.

To assess and evaluate feasibility, we will report on descriptive statistics. Responsiveness will be assessed using Receiver Operating Curve (ROC) analyses.

Intervention

Other:
• Exercise
Participants will be offered to take part in a 5-hour Learning and Mastery-course at Diakonhjemmet Hospital, receiving information about the osteoarthritis disease, symptoms and the importance of exercise and physical activity. Participants will then be given a weekly web-based exercise program (12 weeks) consisting of three aerobic exercise sessions per week. The exercise program consists of five levels, and the participants will each week be guided to the most appropriate level based on their measured physical fitness level and the weekly exercise diary. The participants will at initial assessment at Diakonhjemmet Hospital be instructed to use Borgs scale to adjust exercise level. Based on the weekly exercise diary the participants will also get motivational messages by email.
