歩行再訓練：膝蓋大腿部痛を有するランナー向け
走行再トレーニング介入による膝蓋大腿痛を有する女性ランナーへの効果：ランダム化比較試験
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
時間枠：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
時間枠：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. |
Baseline, Week 6, Week 18
|
|
Anterior Knee Pain Scale
時間枠：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
時間枠：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
時間枠：Baseline, Week 6
|
Ground reaction force (GRF) will be measured during overground running using embedded force plates synchronized with motion capture. |
Baseline, Week 6

|
Visual Analogue Scale for the worst pain
時間枠：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. |

Step rates
時間枠：Baseline, Week 6
|
Step rates refer to the number of steps taken per unit of time, usually expressed as steps per minute (steps/min). |
Baseline, Week 6

Weekly running distance
時間枠：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. |
