简要总结
Patellofemoral pain syndrome (PFPS) is a multifactorial musculoskeletal condition that is common particularly among young and physically active individuals, negatively affecting activities of daily living and physical performance. Although exercise therapy is considered the gold standard in the management of PFPS, there is limited evidence regarding the effectiveness of motor learning strategies applied during exercise. This study aims to shed light on how motor learning approaches can be optimized in clinical rehabilitation by comparing the effects of internal and external focus strategies used during exercise on muscle activation, functional performance, and pain.
This research will make a methodological contribution to the literature through the objective evaluation of muscle mechanical properties using isokinetic assessment and the MyotonPRO device. The findings are expected to clarify the effects of attentional focus strategies on therapeutic outcomes in PFPS rehabilitation and have the potential to provide an evidence-based guide for physiotherapy practice. In this way, the study may contribute to the development of new approaches aimed at improving both clinical effectiveness and patient adherence.

结局指标
主要结局
Kujala Patellofemoral Pain Score
时间窗: baseline
Kujala Patellofemoral Pain Score is a valid and reliable self-reported outcome measure specific to patellofemoral pain syndrome that assesses knee function and pain-related limitations during daily activities. The total score ranges from 0 to 100, with higher scores indicating better knee function and fewer symptoms.
Kujala Patellofemoral Pain Score
时间窗: Week 3 of the Treatment
Kujala Patellofemoral Pain Score is a valid and reliable self-reported outcome measure specific to patellofemoral pain syndrome that assesses knee function and pain-related limitations during daily activities. The total score ranges from 0 to 100, with higher scores indicating better knee function and fewer symptoms.
Kujala Patellofemoral Pain Score
时间窗: Week 6 of the Treatment
Kujala Patellofemoral Pain Score is a valid and reliable self-reported outcome measure specific to patellofemoral pain syndrome that assesses knee function and pain-related limitations during daily activities. The total score ranges from 0 to 100, with higher scores indicating better knee function and fewer symptoms.
