简要总结
The purpose of this study is to examine the impact of an OA-specific aerobic and strengthening exercise program, delivered within the workplace, on mobility, pain, physical capacity, and resilience among workers with knee or hip OA as well as those with no joint pain. The investigators hypothesize that exercise designed for OA, delivered at work, will improve all of these outcomes.
详细描述
The Canadian workforce is aging. The most prevalent age group is 50-54 years and most of these Canadians will aim to continue working over the next 10 years. However, the impact of arthritis on aging Canadians compromises their ability to continue working. By 2031, over 2 million Canadians aged 45 to 64 years will have arthritis. The investigators aim to boost the ability of adults with the most common arthritis, osteoarthritis (OA), as well as adults without OA, to engage in the workforce for as long as they desire. Identifying strategies to promote productivity among workers with knee and hip OA will be of great public health significance in the coming decades. However, the investigators face two challenges. First, obesity among sedentary workers is a risk for worsening knee and hip OA. Second, large occupational loads on the knee and hip worsen OA. Exercise has the most promise in addressing these challenges because it reduces pain and sick time, and improves mental health. Thus, there is a call for studies examining exercise for workers with knee and hip OA.

研究组 & 干预措施
Exercise
The participants in this arm will be asked to attend 3 group classes per week for 12 weeks taught by a certified exercise instructor. Five class times will be offered per week. These classes included a warm-up, static poses shown to decrease knee joint loading, and a cool down including flexibility exercises. Measurements will be obtained at baseline (before intervention) and at follow-up (following intervention). Outcomes included clinical mobility; pain; isometric leg strength; cardiovascular fitness; and resilience.
干预措施: Exercise (Other)
No Exercise
The participants in this arm will be asked to refrain from changing their physical activity over the 12 weeks and maintain any strategies typically used to manage knee and/or hip pain. Since it is known that exercise is beneficial for pain management and strengthening in knee OA, participants randomized to the no exercise group will be offered the same exercise program following completion of the study. Measurements will be obtained at baseline (before intervention) and at follow-up (following intervention). Outcomes included clinical mobility; pain; isometric leg strength; cardiovascular fitness; and resilience.

结局指标
主要结局
Change in Lower Extremity Functional Scale
时间窗: Weeks 1 and 13
The Lower Extremity Function Scale (LEFS) consists of 20 items, on an adjectival scale, that assess difficulty during mobility tasks ranging from transfers to running. Each item is scored from 0 (extreme difficulty or unable to perform activity), to 4 (no difficulty to perform activity). The minimum possible score is 0, and the maximum possible score is 80. Scores closer to 80 represent better self-reported physical function. It is reliable and valid in knee OA and has superior sensitivity to change compared to similar measures
