Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Low back pain intensity – measured using the McGill Pain Questionnaire at two time points: before the intervention and three months after the intervention. Functional disability – measured using the Roland-Morris Disability Questionnaire at two time points: before the intervention and three months after the intervention. Timepoint: Before the intervention and three months after the intervention. Method of measurement: Low back pain intensity: Measured using the validated Persian version of the Short-Form McGill Pain Questionnaire. Functional disability: Measured using the validated Persian version of the Roland–Morris Disability Questionnaire. | — |

| Measure | Time frame |
|---|---|
| Functional Movement Screen (FMS) score. Timepoint: Baseline and end of week 12 (post-intervention). Method of measurement: The Functional Movement Screen comprising seven standardized tasks is administered and scored by a trained assessor following the official manual. After uniform instructions and a brief familiarization, each task is scored from zero to three; the sum is recorded as the total score.;Y-Balance Test (YBT) score. Timepoint: Baseline and week 12. Method of measurement: The Y Balance Test is performed in the anterior, posteromedial, and posterolateral directions. Three valid trials are recorded per direction. Limb length is measured from the anterior superior iliac spine to the medial malleolus, and the composite score is calculated after normalization to limb length under standardized procedures.;Gait speed during comfortable walking. Timepoint: Baseline; week 12. Method of measurement: Participants walk along a straight walkway at a comfortable, steady pace. Gait is captured using the Qualisys optical motion capture system with a standardized lower-limb marker set at a sampling frequency of at least one hundred hertz. Acceleration and deceleration zones at the beginning and end are excluded, and gait speed is calculated as distance divided by elapsed time.;Percentage of plantar contact area on Foot-scan. Timepoint: Baseline and week 12. Method of measurement: Plantar pressure is recorded during comfortable over-ground walking using a calibrated Foot scan pressure platform with a sampling frequency of at least one hundred hertz. The software identifies contact pixels using a predefined threshold. Heel, midfoot, forefoot (and toes if required) are defined by standardized regional masks, and the “percentage of contact area of each region relative to the total plantar contact area” is computed and recorded. At least three valid steps per limb are collected and averaged. | — |
