Intervention / Treatment
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.

---|---|
Experimental: Intervention group
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.
|
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.

Changes in objectively measured physical activity
Time Frame: 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.
|
baseline and 12 weeks
|
Change in physical fitness (VO2 peak)
Time Frame: 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.

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.
