- Brief 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.
- Detailed 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.

Group Intervention Description Intervention group Exercise Participants allocated to the intervention group will be familiarized with exercise intensity levels (heart rate and Borg RPE) during the assessment at Diakonhjemmet Hospital. Further, the patients will be offered to take part in a 5-hour Learning and Mastery-course at Diakonhjemmet Hospital. Thereafter, the participants will get access to a web-based exercise program and guided to choose the appropriate exercise-level. Weekly, based on the individual progression, all participants will receive an exercise program by email consisting of individually tailored exercise sessions and motivational messages. At the end of each week, the participants complete an electronic exercise diary for monitoring adherence. All participants will be offered the possibility to seek peer-support; however, if preferred they may also follow the exercise program by themselves.
- Primary Outcome Measures
Name Time Method Feasibility: time resources used by peer-supporters baseline to 12 weeks Time (hours/minutes) per participant-peer-support contact (frequency of contacts divided by total time used by peer-supporters).
Feasibility: time resources used on the exercise program delivery baseline to 12 weeks Time (hours/minutes) per week per participant used on web-based exercise program delivery.
Feasibility: time resources used on motivational messages delivery baseline to 12 weeks Time (hours/minutes) per week per participant used on motivational message delivery.
Feasibility: proportion of received exercise diaries baseline to 12 weeks Proportion of received exercise diaries (0-12 per participant).
Feasibility: proportion wearing the activity monitor baseline Proportion of participants providing activity monitor data (at least 4 days, including one weekend day, with minimum 10 hours recording per day) at baseline.
Feasibility: proportion completing treadmill test baseline Proportion of participants completing the indirect maximal cardiorespiratory exercise test according to test-protocol at baseline.
Eligible: proportion eligible baseline Proportion of potentially eligible participants approached that are invited.
Recruitment: proportion enrolled baseline Proportion of eligible patients enrolled.
Retention: proportion of enrolled participants baseline and 12 weeks Proportion of enrolled participants providing data at 12 week post-test.
Adverse events: number of adverse events 12 weeks Total number of adverse events (by cause if possible) evaluated by answers at post-test: The four questions addressing possible adverse events: 1) Have you carried out any type of treatment during the last 3 months? (With treatment we mean medication, physical exercise, self-management course or any alternative treatments) (yes/no), 2) If yes, have you experienced any adverse event as a result of the treatment? (yes/no). 3) If yes, which adverse events as a result of treatment? 4) In your opinion, which treatment(s) do you think the adverse event was/were caused by? (medication, physical exercise, self-management course, alternative treatments, other) (Elaborate).
- Secondary Outcome Measures
Name Time Method Changes in objectively measured physical activity baseline and 12 weeks Assessed by accelerometer (ActiGraph GT3X+): Change in physical activity level measured as counts per minute (CPM), which is the total number of registered counts for all valid days divided by wear time. Thresholds for CPM will be used in calculation of time (minutes per week/day) spent on sitting (\<100 CPM), and on light (100-2019 CPM), moderate-(\>2019-5998 CPM) and vigorous (\>5998) intensity physical activity.
Change in physical fitness (VO2 peak) baseline and 12 weeks Change in VO2 peak measured by indirect maximal cardiorespiratory exercise test (modified Balke-protocol). The indirect estimation of VO2 peak by prediction equations is based on incline, grade and speed at end stage, weight and age.
Change in Hip disability and Osteoarthritis Outcome Score (HOOS) baseline and 12 weeks Change in the last week disability on five subscales; pain (10 items, scale 0-40), symptoms (5 items, scale 0-20), function in daily living (17 items, scale 0-68), function in sport and recreation (4 items, scale 0-16) and quality of life (4 items, scale 0-16). Items are scored by a five-point Likert scale ranging from 0 (least severe) to 4 (most severe). Total sum-score and subscale sum-scores will be converted to normalized scores ranging from 0 (extreme disability) to 100 (no disability).
Change in Knee disability and Osteoarthritis Outcome Score (KOOS) baseline and 12 weeks Change in the last week disability on five subscales; pain (9 items, scale 0-36), symptoms (7 items, scale 0-28), function in daily living (17 items, scale 0-68), function in sport and recreation (5 items, scale 0-20) and quality of life (4 items, scale 0-16). Items are scored by a five-point Likert scale ranging from 0 (least severe) to 4 (most severe). Total sum-score and subscale sum-scores will be converted to normalized scores ranging from 0 (extreme disability) to 100 (no disability).
Change in Patient-specific functional scale (PSFS) baseline and 12 weeks Patients will address one to three activities they have problems performing due to osteoarthritis. The degree of difficulty with performing these activities is rated from 0 (cannot perform the activity) to 10 (no problems).
Change in self-reported physical activity (International Physical Activity Questionnaire-Short Form) baseline and 12 weeks Measured by The International Physical Activity Questionnaire-Short Form: Change in time (minutes per week/day) and Metabolic Equivalent of Task (MET-minutes per week/day) spent on sitting, walking, and moderate- and vigorous intensity physical activity the last week (0-7 days). METs are calculated by using the corresponding MET-values for walking (3.3 MET), and moderate-(4.0 MET) and vigorous (8.0 MET) intensity physical activity.
Change in self-reported physical activity (HUNT) baseline and 12 weeks Measured by the three questions from the Nord-Trøndelag Health study (HUNT): change in average frequency (never/\<1 per week/1 per week/2-3 per week/almost every day), intensity (easy without losing my breath or breaking into a sweat/so hard that I lose my breath and break into a sweat/I push myself to near-exhaustion) and duration (less than 15 minutes/15-29 minutes/30 minutes to 1 hour/more than 1 hour) of physical activity.
Change in self-reported pain intensity the last week baseline and 12 weeks Measured by numeric rating scale ranging from 0 (no pain) to 10 (worst pain).
Change in self-reported fatigue the last week baseline and 12 weeks Measured by numeric rating scale ranging from 0 (no fatigue) to 10 (worst fatigue).
Change in self-reported disease activity the last week baseline and 12 weeks Measured by numeric rating scale ranging from 0 (good, no symptoms) to 10 (very bad, much symptoms).
Change in Health-related quality of life (EQ-5D-5L) baseline and 12 weeks EQ-5D-5L will be used for measuring health-related quality of life (www.euroqol.org): comprises five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has five levels of answers (no problems, slight problems, moderate problems, severe problems, and extreme problems). The average score on each dimension will be reported, and the total score can be calculated into an index value ranging from -0.59 to 1, where -0.59 represents worst possible state and 1 represents perfect health.
Change in Arthritis Self-Efficacy Scale (ASES) baseline and 12 weeks Measured by Arthritis Self-Efficacy Scale (ASES): comprises 11 items addressing pain and symptoms (scored on a 5-point scale ranging from not confident at all to very confident). The scores are summed up to a 0-100 score where higher score indicate better self-efficacy.
Change in exercise self-efficacy baseline and 12 weeks Measured by Exercise Beliefs and Exercise Habits questionnaire: comprises 20 items addressing exercise self-efficacy (4 items), barriers to exercise (3 items), benefits of exercise (5 items), and impact of exercise on arthritis (8 items), scored on a 5-point Likert scale ranging from strongly disagree to strongly agree. The scores on each subscale is summed up where higher scores indicate better self-efficacy.
