Design outcomes
Primary
| Measure | Time frame |
|---|---|
| A reduction in the average pain intensity of at least 2 on a 0-10 numeric pain scale is expected immediately after the intervention in both groups. However, greater magnitude changes and effect sizes are anticipated for the early intervention group compared to the delayed one. Additionally, gains are expected to be maintained after 3, 6, and 12 months for those in the early intervention group, but not for those in the delayed intervention group.;An increase in the average self-reported function of at least 16 points on 'The Patellofemoral Pain and Osteoarthritis Subscale of the KOOS' is expected immediately after the intervention in both groups. However, greater magnitude changes and effect sizes are expected for the early intervention group compared to the delayed one. Additionally, gains are expected to be maintained after 3, 6, and 12 months for those in the early intervention group, but not for those in the delayed intervention group. | — |
Secondary
| Measure | Time frame |
|---|---|
| An improvement in self-reported recovery as assessed by the 'Global Rating of Change Scale (GROC)' is expected immediately after the intervention in both groups. However, larger magnitude improvements are expected for the early intervention group compared to the delayed one. Additionally, gains are expected to be maintained after 3, 6, and 12 months for those in the early intervention group, but not for those in the delayed intervention group.;A reduction in physical activity-related fear of movement, indicated by a decrease in the final score in the physical activity domain of the 'Fear Avoidance Belief Questionnaire (FABQ)', is expected immediately after the intervention in both groups. However, greater magnitude improvements and effect sizes are expected for the early intervention group compared to the delayed one. Additionally, gains are expected to be maintained after 3, 6, and 12 months for those in the early intervention group, but not for those in the delayed intervention group.;A reduction in kinesophobia, indicated by a decrease in the final score of the 'Tampa Scale of Kinesiophobia' questionnaire, is expected immediately after the intervention in both groups. However, greater magnitude improvements and effect sizes are expected for the early intervention group compared to the delayed one. Additionally, gains are expected to be maintained after 3, 6, and 12 months for those in the early intervention group, but not for those in the delayed intervention group.;A reduction in pain catastrophizing, indicated by a decrease in the final score of the 'Pain Catastrophizing Scale' questionnaire, is expected immediately after the intervention in both groups. However, greater magnitude improvements and effect sizes are expected for the early intervention group compared to the delayed one. Additionally, gains are expected to be maintained after 3, 6, and 12 months for those in the early intervention group, but not for those in the delayed intervention group.;A reduct | — |
