Gangtræning for løbere med patellofemoral smerte
Gangtræningsintervention for kvindelige løbere med patellofemoral smerte: Randomiseret kontrolleret forsøg
Patellofemoral pain (PFP) is a common overuse injury in runners. Increased patellofemoral joint stress (PFJS) is an important biomechanical factor associated with PFP. Gait retraining, especially cadence modification, may reduce PFJS and improve symptoms, but evidence from randomized controlled trials remains limited. This study investigated whether wearable device-assisted gait retraining was more effective than education alone in reducing pain, improving function, and altering running biomechanics in female runners with PFP.

Visual Analogue Scale for Pain during running
Tidsramme: Baseline, Week 6, Week 18
|
The Visual Analogue Scale (VAS) is a validated, widely used instrument for assessing subjective pain intensity. It consists of a 10-centimeter horizontal line, with one end (0) representing "no pain" and the other end (10) representing "worst imaginable pain." It will be evaluated during running. |

Visual Analogue Scale for usual pain
Tidsramme: Baseline, Week 6, Week 18
|
The Visual Analogue Scale (VAS) is a validated, widely used instrument for assessing subjective pain intensity. It consists of a 10-centimeter horizontal line, with one end (0) representing "no pain" and the other end (10) representing "worst imaginable pain." It will be evaluated for usual pain. |

Anterior Knee Pain Scale
Tidsramme: Baseline, Week 6, Week 18
|
The Anterior Knee Pain Scale (AKPS), also referred to as the Kujala Score, is a patient-reported outcome measure designed to evaluate symptoms and functional limitations associated with anterior knee pain and patellofemoral disorders. It consists of 13 items covering domains such as pain during various activities (e.g., walking, running, jumping, climbing stairs, squatting), functional limitations, abnormal gait, muscle atrophy, and difficulty with prolonged sitting. Each item is scored on an ordinal scale, and the total score ranges from 0 to 100, with higher scores indicating better knee function and fewer symptoms. |
Baseline, Week 6, Week 18
|
|
Knee Flexion Angle
Tidsramme: Baseline, Week 6
|
Peak knee flexion angle will be assessed during running trials using a 3-dimensional motion capture system. Reflective markers will be placed according to a standard lower-limb biomechanical model. |
Baseline, Week 6
|
|
Ground Reaction Force
Tidsramme: Baseline, Week 6
|
Ground reaction force (GRF) will be measured during overground running using embedded force plates synchronized with motion capture. |

Visual Analogue Scale for the worst pain
Tidsramme: Baseline, Week 6, Week 18
|
The Visual Analogue Scale (VAS) is a validated, widely used instrument for assessing subjective pain intensity. It consists of a 10-centimeter horizontal line, with one end (0) representing "no pain" and the other end (10) representing "worst imaginable pain." It will be evaluated for the worst pain. |

Weekly running distance
Tidsramme: Baseline, Week 6
|
Weekly running distance refers to the total distance covered by a participant through running over one week, usually expressed in kilometers (km) or meters (m). This outcome is used to assess running volume. |
