简要总结
Eight weeks of telehealth-based supervised exercise effectively reduced DKV and pain in women with anterior knee pain. Both intervention groups demonstrated comparable benefits.
详细描述
This study compared the effects of knee strengthening combined with either hip or ankle joint exercises on dynamic knee valgus (DKV), visual analogue scale (VAS) scores during activity, tendon stiffness, muscle structure, ankle range of motion, and muscle strength in women with anterior knee pain. Forty-five female recreational athletes aged 20-40 with anterior knee pain were randomly assigned to three groups: hip + knee exercises (HK group, n = 15), ankle + knee exercises (AK group, n = 15), and stretching alone (control group, n = 15). The HK and AK groups received supervised telehealth-based exercise sessions (30 minutes/day, 3 times/week for 8 weeks), while the control group received only an educational pamphlet. Assessments were conducted at baseline, 4 weeks, and 8 weeks.

结局指标
主要结局
Single Leg Landing Task
时间窗: 2 minute
The participant stood on a 30 cm box and first bent the non-testing leg's knee to approximately 90 degrees. After stabilizing, the participant jumped forward with the testing leg to a target 10 cm away from the box, maintaining balance for five seconds upon landing.
次要结局

- Patellar Tendon Stiffness Measurement(3 minute)
- Muscle structure(15 minute)
