Study Overview
Brief Summary
Physical activity level is measured at baseline and after 3 and 12 months after structured information and individually adapted exercise for patients with osteoarthritis in hip or knee.
The hypothesis of this study is that a supported self management of osteoarthritis program will increase the level of physical activity in patients with osteoarthritis in hip or knee. The second hypothesis is that patients with osteoarthritis in knee will increase their level of physical activity more than patients with osteoarthritis in hip.
Detailed Description
Osteoarthritis (OA) is one of our most common chronic joint disorders. The World Health Organization (WHO) has estimated that every second woman and every fourth man over the age of 60 suffer some form of OA. OA is most common in hands, knee, hip and back. OA is a rheumatic disorder which affects the whole joint and may start as early as in the age of 30. The main symptoms are pain, stiffness and decreased quality of life.
The primary goals of OA management are to reduce the symptoms. Patient education and exercises are recommended as basic treatment according to national as well as international guidelines.
It is known that the level of physical activity decreases with age and that woman are less physical active than men. A study of healthy women older than 56 years showed that the level of activity decreased by 10 minutes per year, for every five year increase in age. OA is more common in women and is an irreversible disease, which means that the proportion of older women with osteoarthritis is large.
In addition OA is the most common cause of inactivity among the elderly and many fear that activity will further damage the joints. Inactivity is a large risk factor for poor physical and psychological health as well as premature death. Level of physical activity in people with OA has mainly been evaluated by self-assessment questionnaires. People with hip OA are more active than people with knee OA and the correlation between the degree of radiographic changes and physical activity is weak. Only 30% with early OA of the knee in the age group 35-65 years meet the recommendations for physical activity performed at least 30 minutes per day of moderate intensity, five days per week, measured by an accelerometer.
The primary aim of this study is to determine the effects of structured information and individually adapted exercises, delivered as a supported self-management osteoarthritis program, on overall levels of physical activity of moderate and vigorous intensity in patients with hip or knee OA. The secondary aim is to compare the level of physical activity in patients with hip and knee OA.

Outcomes
Primary Outcomes
Level of Physical Activity/Low Activity
Time Frame: baseline, 3 months and12 months
Level of physical activity will be monitored by an accelerometer at baseline and at 3 and 12 months after the supported self-management of osteoarthritis program using an accelerometer. The GT1M Actigraph is a small uniaxial accelerometer that measures vertical acceleration and deceleration. Accelerometer output is an activity "count" which is the weighted sum of the number of accelerations measured over a period (e.g. in this case 10 seconds). Participants will be instructed to wear the accelerometer from morning, and continuously (except for water activities) until going to bed at night, for seven consecutive days. The accelerometer will be attached to a belt to wear around the waist with accelerometer placement on the right hip.
Level of Physical Activity/Moderate-vigorous Activity
Time Frame: baseline, 3 month and 12 month
Level of physical activity will be monitored by an accelerometer at baseline and at 3 and 12 months after the supported self-management of osteoarthritis program using an accelerometer. The GT1M Actigraph is a small uniaxial accelerometer that measures vertical acceleration and deceleration. Accelerometer output is an activity "count" which is the weighted sum of the number of accelerations measured over a period (e.g. in this case 10 seconds). Participants will be instructed to wear the accelerometer from morning, and continuously (except for water activities) until going to bed at night, for seven consecutive days. The accelerometer will be attached to a belt to wear around the waist with accelerometer placement on the right hip.
Level of Physical Activity/Sedentary Time
Time Frame: Baseline, 3 months and 12 months
The level of physical activity will be monitored by a GT1M Actigraph which is a small uniaxial accelerometer that measures vertical acceleration and deceleration. Accelerometer output is an activity "count" which is the weighted sum of the number of accelerations measured over a period (e.g. in this case 10 seconds). Participants will be instructed to wear the accelerometer from the morning, and continuously (except for water activities) until going to bed at night, for seven consecutive days. The accelerometer will be attached to a belt to wear around the waist with accelerometer placement on the right hip. The account of minutes in sedentary time will be calculated and the average of minutes in one week will be used.
Secondary Outcomes
- Health Realted Quality of Life(baseline, 3 months and 12 months)
- Visual Analog Scale for Pain(baseline, 3 months and 12 months)
- Arthritis Self-efficacy Scale/Pain (ASES)(baseline, 3 months and 12 months)
