Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Directional Preference status, Directional Preference status is categorized into three groups: stable (direction remains the same before and after treatment), changed (direction changes after treatment), or newly developed (directional preference appears after treatment). Timepoint: before the intervention (baseline) and after completion of three treatment sessions (post-intervention). Method of measurement: Assessed using the standards McKenzie Lumbar Assessment Form by a certified McKenzie therapist. Directional preference is determined based on the patient's response to repeated movements in different directions. | — |
Secondary
| Measure | Time frame |
|---|---|
| Intensity and quality of pain. Timepoint: Before intervention and after three treatment sessions. Method of measurement: Short-Form McGill Pain Questionnaire (SF-MPQ).;Flexion and extension range of motion of the lumbar spine. Timepoint: Before intervention and after three treatment sessions. Method of measurement: Using TiltMeter smartphone application installed on an iPhone. | — |
