简要总结
The focus of this pilot study is to evaluate the feasibility of utilizing an evidenced-based high intensity interval training program (HIIT) to improve physical function in patients with knee osteoarthritis (OA).
详细描述
All participants will be assigned to the single-arm of the study in which all participants will receive 12 weeks of HIIT, delivered twice per week. The primary outcome will examine the feasibility and acceptability of the 12 week HIIT program in patients with knee OA symptoms ranging from mild to severe. The investigators will determine adherence to and tolerability of HIIT, acceptability, and recruitment and retention rates during the 12 week program. Additional outcomes will include physical function, knee OA symptomatic burden (pain), static standing balance, isometric knee extensor and flexor strength, cardiorespiratory fitness, and body composition.
