Summary

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.

Conditions

• Patellofemoral Pain, PFP

Interventions

Type	Name	Description
OTHER	Internal focus group	Internal focus refers to directing attention to one's own body movements or muscle activity while performing a task (e.g., focusing on contracting a specific muscle). During isokinetic strength exercises, this group is instructed with commands such as: "Tighten your quadriceps" and "Straighten your knee."
OTHER	External focus	External focus refers to directing attention to the effect of a movement on the environment or an external object, rather than on the body itself. During isokinetic exercise, this group is given the instruction: "Increase and maintain the performance indicator on the screen."
