Inclusion criteria
Inclusion criteria: Workers of both sexes; aged between 18 and 65 years; affiliated with the University Hospital of the Federal University of Juiz de Fora; identified and monitored by the Occupational Health sector; presenting nonspecific chronic low back pain lasting more than six months; able to perform their usual work activities at the time of the research; voluntarily agreeing to participate in the study.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To assess the intensity and interference of low back pain, verified through the Brief Pain Inventory (BPI), applied before and after each experimental session. It will be observed whether there is a difference in pain intensity scores and functional interference between the conditions with and without the use of the passive lumbar exoskeleton | — |
Secondary
| Measure | Time frame |
|---|---|
| To assess the perception of effort during the performance of work activities. The outcome will be verified using the Borg Scale of perceived exertion, applied before the workday and immediately after its completion. It will be observed whether there is a difference in perceived exertion scores between the conditions with and without the use of the passive lumbar exoskeleton;To assess perceived fatigue at the end of the workday. The outcome will be verified using the Fatigue Pictogram, applied at the end of each experimental workday. It will be observed whether there is a difference in the intensity and impact of reported fatigue between the conditions with and without the use of the passive lumbar exoskeleton;To assess the functional performance of workers. The outcome will be verified through the 30-second sit-to-stand test. It will be observed whether there is a difference in the number of repetitions of the functional test between the conditions with and without the use of the passive lumbar exoskeleton;To evaluate the autonomic response to exertion during the workday, verified through heart rate variability, continuously recorded with a heart rate monitor. It will be observed whether there is a difference in heart rate variability indices, in the time and frequency domains, between the conditions with and without the use of the passive lumbar exoskeleton;To assess the subjective perception of comfort and suitability of the passive exoskeleton. The outcome will be verified through participant reports after using the device. It will be observed whether participants report acceptability, comfort, and suitability of the exoskeleton to the work environment | — |
