Подробное описание
Arthritis is the leading cause of disability in the United States. Osteoarthritis (OA) is the most common type of arthritis and affects nearly 27 million Americans. Knee OA is the most common type of osteoarthritis and is estimated to affect 42.1% of women and 31.2% of men over the age of 60.
Osteoarthritis is most likely multi-factorial with several underlying causes. It is no longer considered "a degenerative joint disease" but rather a process that involves dynamic biomechanical, biochemical, and cellular processes. It not only involves degeneration of the articular cartilage, but also inflammation of the synovium, changes to the underlying subchondral bone, and the development of osteophytes. Currently, it appears that numerous systemic factors can lead to the initiation of OA through different causal pathways . These systemic causes can then be amplified by local factors such as trauma or increased loading caused by obesity.
Currently, there is no "cure" for OA and attempts to find a disease modifying drug have been unsuccessful. Thus, treatment currently focuses on mitigating factors that are known to affect the radiographic progression of the disease as well as lead to activity limitation and participation restriction.9,10 Decreases in lower extremity strength are a major cause of activity limitations given the vital role of strength in activities of daily living.
One method that is used to mitigate progressing factors is through the use of an exercise program. Many types of exercise have been used successfully in the literature including resistance training. Resistance training can take many different forms such as isometric, isotonic (concentric and/or eccentric) or isokinetic with various intensities. Presently, there is little evidence for the use of eccentric training interventions for patients with knee OA. This study aims to further examine this type of resistance training for the OA population. Therefore, the purpose of this study is to examine the effects of low intensity, long duration eccentric resistance training and high intensity, short duration eccentric resistance training in individuals with knee OA. Ideally, this study will allow us to determine the overall effects of eccentric resistance training as well as the potential differences of the two types of eccentric resistance training.
