Eligibility
Inclusion criteria
Inclusion criteria: 69 older adults with knee OA who are not already engaged in regular PA will be recruited. Potential participants will be assessed through an admission questionnaire and a face-to-face interview by the Research Coordinator to ensure that they meet the study?s selection criteria. The inclusion criteria include: 1. Diagnosed with OA of the knee, based on the clinical symptoms of OA following the American College of Rheumatology (ACR) criteria for knee, including radiographic evidence according to the Kellgren-Lawrence grading scale during a radiological assessment of OA (Grade 1 - 4) 2. Aged over 40 years old 3. No evidence of mental health condition 4. Able to walk for a minimum of 20 minutes at their own pace 5. Available three times a week over a period of 12 months (for 45 minutes during the operating hours of the Walking Club; i.e. 7:30 to 10:00 am)
Exclusion criteria
Exclusion criteria: 1. No confirmation of an OA diagnostic of the knee, based on the clinical symptoms of OA following the ACR criteria for knee, including radiographic evidence according to the Kellgren-Lawrence grading scale during a radiological assessment of OA (Grade 1 - 4) 2. Healthy individual 3. Younger than 40 years old 4. Uncontrolled hypertension: Systolic BP >160 mm Hg 5. Individuals who are obese (BMI > 30 kg/m2) 6. Not able to walk for a minimum of 20 minutes at their own pace 7. Unavailable three times a week over a period of 12 months (for 45 minutes during opening hours of the Walking Club) 8. Other illness, judged by the patient or study physician to make participation in this study inadvisable 9. Following a concomitant OA treatment at the same period (e.g. physiotherapy, acupuncture, etc.) 10. Participating in regular physical activities more than two times per week for more than 20 minutes per session 11. Cognitive deficits resulting in inability to understand instructions 12. Inability to communicate in English or French 13. Surgery planned in the next year 14. Intention to move away from Ottawa in the next year
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Adherence will be measured to determine the effect of the type of supervision (supervised vs. unsupervised) on the sustainability of the walking program. Program adherence to treatment will be monitored and calculated as a proportion of the number of walking sessions attended divided by the number of walking sessions prescribed (3 times a week as recommended in the Ottawa Panel guidelines, 2012) and recorded in the participants? logbooks (each week). The calendar proposed by the 7-Day Physical Activity Recall (PAR) incorporated in the logbooks will be used as a self-report questionnaire, to calculate the number of walking sessions each participant will attend each week. It is important to note that this method of assessment was used in various RCTs that studied the impact of walking programs in the management of OA among older individuals. In fact, Rauh et al. (1992) showed that the PAR appeared to be administratively feasible and demonstrated relevant validity. Several trials confirmed that a daily recording is more accurate among an older population when self-reporting with an electronic system. For the supervised group (S), we will take the attendance at the walking club to confirm what is writing in the walkers' logbooks. The logbook will also be used as a tool to measure other valid measurements of the physical activity level, using METS, pedometric and walking endurance measurements. The use of pedometers to monitor walking attendance in older adults appears to be another reliable and valid instrument. Generally used by elderly people, pedometers are easy to use and provide an objective measurement of walking adherence. | — |
Secondary
| Measure | Time frame |
|---|---|
| All the secondary outcomes measures will be assessed each 3 months. 1. Quality of life will be assessed using the ?EuroQoL Index (EQ-5D-5L)?. This generic instrument is the most commonly used and extensively validated measure of health-related quality of life. Five domains are included in this measure: 1.1 mobility 1.2 self-care 1.3. usual activities 1.4. pain/discomfort 1.5. anxiety/depression Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. It is important to mention that the EQ-5D-5L was used to measure quality of life in various RCTs that studied the impact of walking programs in the management of OA, in older people. 2. Three secondary outcomes, pain, stiffness and functional status, will be measured using the ?Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)? questionnaire. This five-point questionnaire contains 3 dimensions: pain (5 questions), stiffness (2) and function (17). The WOMAC instrument has been used to report pain and functional status in several RCTs involving walking programs designed for individuals with OA. 3. Gait speed (time to walk 6 meters), Timed-up-and-Go (TUG) test and the Number of steps completed during the walking sessions measured with a pedometer. 4. Self-efficacy will be measured with the Chronic Disease Self-Efficacy Scale www.patienteducation.stanford.edu/) which is a multidimensional scale including 4.1. Self-Efficacy to Perform Self-Management Behaviours 4.2. General Self-Efficacy 4.3. Self-Efficacy to Achieve Outcomes 5. In addition, PA behaviour will be measured with an adapted PACE instrument (www.paceproject.org/Measures.html). The PACE instrument measures PA behaviours and is a multidimensional tool measuring: 1) | — |
