Registered outcomes 6
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Repeated Trunk Flexion (RTF) Performance | Baseline and immediately after the 5-week intervention | Dynamic trunk movement performance was assessed using the Repeated Trunk Flexion (RTF) test. Participants performed 10 consecutive trunk flexion-extension movements from a standing position as quickly as possible, reaching their available range of motion and returning to an upright position. The test was performed twice, and the average completion time of the two trials was recorded in seconds. Lower values indicate better performance. | ClinicalTrials.gov |
| Secondary | Flexor Endurance Test (FET) | Baseline and immediately after the 5-week intervention. | Trunk flexor muscle endurance was assessed using the Flexor Endurance Test (FET). Participants maintained a 60-degree trunk flexion position for as long as possible until fatigue or loss of the required position. Endurance time was recorded in seconds. Higher values indicate better trunk muscle endurance. | ClinicalTrials.gov |
| Secondary | Oswestry Disability Index (ODI) | Baseline and immediately after the 5-week intervention. | Low back pain-related disability was assessed using the Oswestry Disability Index (ODI), version 2.1a. The questionnaire consists of 10 sections assessing limitations in daily activities. Scores are expressed as a percentage ranging from 0% (no disability) to 100% (maximum disability). Lower scores indicate less disability | ClinicalTrials.gov |
| Secondary | Numerical Pain Rating Scale (NPRS) | Baseline and immediately after the 5-week intervention. | Pain intensity was assessed using the Numerical Pain Rating Scale (NPRS), an 11-point scale ranging from 0 (no pain) to 10 (worst imaginable pain). Higher scores indicate greater pain intensity. | ClinicalTrials.gov |
| Secondary | Tampa Scale of Kinesiophobia (TSK) | Baseline and immediately after the 5-week intervention. | Fear of movement and reinjury was assessed using the 17-item Tampa Scale of Kinesiophobia (TSK). Each item is rated on a 4-point Likert scale. Total scores range from 17 to 68, with higher scores indicating greater fear of movement or reinjury. | ClinicalTrials.gov |
| Secondary | Pressure Pain Threshold (PPT) | Baseline and immediately after the 5-week intervention. | Mechanical pain sensitivity was assessed using a Wagner FPN 100 pressure algometer applied bilaterally over the lumbar erector spinae muscles, approximately 5 cm lateral to the L3 spinous process. Three measurements were obtained on each side and averaged. An overall pressure pain threshold was calculated as the mean of the left and right values. Higher values indicate lower mechanical pain sensitivity. | ClinicalTrials.gov |
