简要总结
This study is a detailed assessment of the maximal rate of force development of ankle muscles and its association with functional ability in patients with knee osteoarthritis (OA).
详细描述
This research is designed to study the link between force development in ankle muscles and functional abilities in knee OA patients. It aims to understand the influence of ankle muscle strength, specifically plantar flexors, on the stability, pain, and functionality of patients with knee OA. The study will analyze the rate of force development, its importance in explosive strength improvement, and impact on preventing knee injuries. Furthermore, it will investigate the compensatory mechanism of the plantar flexors developed by patients in advanced stages to balance other muscle failures.

结局指标
主要结局
Rate of Force Development (RFD)
时间窗: Baseline
The RFD is a measure of the speed at which the force of a muscle contraction develops. It is typically measured during isometric contractions and provides information about the muscle's explosive strength capacity.
Single Leg Hop Test (SLHT)
时间窗: Baseline
n this test, participants hop forward as far as possible on one leg, and the distance hopped is recorded.
Forward Step Down Test (FSDT)
时间窗: Baseline
This functional ability test requires participants to perform as many repetitions as possible in 30 seconds of a specific movement. The number of valid repetitions performed in this duration is recorded.
Knee Osteoarthritis Outcome Score (KOOS)
时间窗: Baseline
The KOOS is a questionnaire that assesses five aspects of knee injury and osteoarthritis: pain, symptoms, ADL function, sport and recreation function, and quality of life. Scores are transformed to a 0-100 scale, with zero representing extreme knee problems and 100 representing no knee problems. Higher scores indicate better function and less pain.
Isokinetic Testing Procedures
时间窗: Baseline
This procedure involves conducting tests of three (60°/s) or five (120°/s) maximal nonconsecutive efforts with specific rest intervals. Each subject is instructed to exert maximal effort throughout the whole range of motion.
