Design outcomes
Primary
| Measure | Time frame |
|---|---|
| A reduction in knee pain intensity is expected after 12 weeks of intervention in both groups, with this reduction being at least 20 mm and greater in the objective monitoring group compared to the self-reported monitoring group, as measured by the Visual Analogue Scale for pain (0–100 mm) at the final assessment.;An improvement in self-reported knee function is expected after 12 weeks of intervention in both groups, as verified by the Knee Injury and Osteoarthritis Outcome Score for Patellofemoral Pain and Osteoarthritis (KOOS-PF, score 0–100) questionnaire, with an improvement of at least 7 points in the total score. This improvement is expected to be greater in the objective monitoring group compared to the self-reported monitoring group at the final assessment.;An improvement in isometric muscle strength for knee extension and flexion is expected after 12 weeks of intervention in both groups, verified by means of maximum voluntary isometric contraction (MVIC) performed using a portable dynamometer to measure torque, with an improvement of at least 14.1 Newtons for extension and 74.6 Newtons for knee flexion, with this improvement being greater in the objective monitoring group compared to the self-reported monitoring group in the final assessment.;Expected improvement in isometric strength of hip abductors and extensors after 12 weeks of intervention in both groups, verified through maximum voluntary isometric contraction (MVIC) performed in side-lying for abductors and prone for extensors, using a portable dynamometer to measure torque, with greater improvement in the Objective Monitoring group compared to the Self-reported Monitoring group at the final evaluation.;Greater adherence to the unsupervised home exercise program is expected in the objective monitoring group compared to the self-reported monitoring group at the final assessment, after 12 weeks of intervention and verified through objective measurements obtained by hidden triaxial accelerometers (Mean | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected increase in physical activity level after 12 weeks of intervention in both groups, verified through the International Physical Activity Questionnaire (IPAQ), with greater increase in the Objective Monitoring group compared to the Self-reported Monitoring group at the final evaluation.;A reduction in kinesiophobia levels is expected after 12 weeks of intervention in both groups, as verified by the Tampa Scale for Kinesiophobia questionnaire, with an improvement of at least 6.16 in the score. This improvement is greater in the objective monitoring group compared to the self-reported monitoring group in the final assessment.;Expected increase in exercise motivation levels after 12 weeks of intervention in both groups, verified through the Behavioral Regulation in Exercise Questionnaire (BREQ-3), with greater increase in the Objective Monitoring group compared to the Self-reported Monitoring group at the final evaluation.;Expected reduction in anxiety and depression levels after 12 weeks of intervention in both groups, verified through the Hospital Anxiety and Depression Scale (HADS), with greater reduction in the Objective Monitoring group compared to the Self-reported Monitoring group at the final evaluation. | — |
