Change From Baseline in Average Low Back Pain Intensity at Month 3
Lasso di tempo: 3 months after randomization
|
Average low back pain intensity during the previous week will be assessed using an 11-point Numerical Rating Scale, ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain.

Change From Baseline in Average Low Back Pain Intensity
Lasso di tempo: Baseline, 1 month, and 6 months after randomization
|
Average low back pain intensity during the previous week will be assessed using an 11-point Numerical Rating Scale, ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain.
|
Baseline, 1 month, and 6 months after randomization
|
|
Change From Baseline in Functional Disability Assessed by the Roland-Morris Disability Questionnaire
Lasso di tempo: Baseline, 1 month, 3 months, and 6 months after randomization
|
Functional disability related to low back pain will be assessed using the Roland-Morris Disability Questionnaire.
Higher scores indicate greater functional disability.
|
Baseline, 1 month, 3 months, and 6 months after randomization
|
|
Global Perceived Recovery
Lasso di tempo: 1 month, 3 months, and 6 months after randomization
|
Overall improvement will be assessed using a 6-point Likert scale ranging from "much worse" to "completely recovered."
|
1 month, 3 months, and 6 months after randomization
|
|
Change From Baseline in Health-related Quality of Life Assessed by EQ-5D-5L
Lasso di tempo: Baseline, 1 month, 3 months, and 6 months after randomization
|
Health-related quality of life will be assessed using the EQ-5D-5L.
The EQ-5D-5L includes five health dimensions, and each dimension has five severity levels.
Higher health utility scores indicate better health status.
|
Baseline, 1 month, 3 months, and 6 months after randomization
|
|
Change From Baseline in Sleep Quality Assessed by the Insomnia Severity Index
Lasso di tempo: Baseline, 1 month, 3 months, and 6 months after randomization
|
Sleep quality and insomnia symptoms will be assessed using the patient-reported version of the Insomnia Severity Index.
The scale contains 7 items evaluating sleep onset difficulty, sleep maintenance difficulty, early morning awakening, satisfaction with sleep, interference with daytime functioning, noticeability of sleep problems, and distress caused by sleep difficulties.
Each item is scored from 0 to 4, and the total score ranges from 0 to 28.
Scores are interpreted as follows: 0-7, no clinically significant insomnia; 8-14, subthreshold insomnia; 15-21, moderate insomnia; and 22-28, severe insomnia.

Baseline, 1 month, 3 months, and 6 months after randomization
|
|
Change From Baseline in Back Pain Beliefs Assessed by the Back Beliefs Questionnaire
Lasso di tempo: Baseline, 1 month, 3 months, and 6 months after randomization
|
Beliefs about back pain will be assessed using the Back Beliefs Questionnaire.
Scores range from 9 to 45, with lower scores indicating more pessimistic beliefs about the consequences of back pain.
|
Baseline, 1 month, 3 months, and 6 months after randomization
|
|
Change From Baseline in Neuropathic Pain Features Assessed by the painDETECT Questionnaire
Lasso di tempo: Baseline, 1 month, 3 months, and 6 months after randomization
|
Neuropathic pain features will be assessed using the painDETECT questionnaire.
A score of 19 or higher suggests the presence of a neuropathic pain component.
|
Baseline, 1 month, 3 months, and 6 months after randomization
|
|
Use of Nonsteroidal Anti-inflammatory Drugs
Lasso di tempo: Baseline, 1 month, 3 months, and 6 months after randomization
|
The amount and frequency of nonsteroidal anti-inflammatory drug use during the study period will be recorded.
|
Baseline, 1 month, 3 months, and 6 months after randomization
|
|
Incidence of Adverse Events
Lasso di tempo: From randomization to 6 months after randomization
|
Adverse events will be recorded throughout the study.
