Rehabilitation for work-related musculoskeletal disorders involves physical, behavioral, psychological treatment and counseling on how to deal with pain and disability. The study aims to evaluate the profile and indicators on the perception of health, pain intensity, and work ability (WA) of disability with work-related chronic musculoskeletal disease, assisted in a multidisciplinary program of worker health care.

The study design is an intervention pre and post, 88 individuals diagnosed with work-related musculoskeletal disorders were followed up during a multidisciplinary program at the Reference Center for Workers' Health of the Unified Health System (SUS), SP, Brazil. The study was carried out six groups of individuals were followed (16 to 21 meetings; 10 to 19 participants). Sociodemographic, occupational, general health, pain intensity, and work ability (WA) were assessed at the baseline. Participants included has work-related musculoskeletal disorders diagnosis and complaints of chronic pain in one or more regions of the body, of different age groups, education levels, income, and occupational status (unemployed, leave work, or is working). Chronic pain is defined as a persistent or recurrent symptom lasting longer than three months. Criteria whose main diagnosis was a work-related mental disorder or musculoskeletal complaints related to previous injuries resulting from an accident or typical displacement from work, such as amputations and fractures, were excluded.

Outcome measure

1. Pain complains - Body region The diagnoses of musculoskeletal diseases were grouped by body segments: cervical spine, lumbar spine, upper limbs and lower limbs. Pain complaints reported by individuals were also grouped by segments: cervical, lumbar, more than one spinal segment, upper limbs, lower limbs, two areas of the body, three or more body region.

2. Pain intensity To measure pain intensity, the Numerical Rating Scale was used, an instrument that presents itself as a numbered line from zero (no pain) to ten points (maximum pain). Individuals responded about pain in the last seven days and in the last month.

3. Work ability - using two questions (current and future work ability). Based on the Work Ability Index (WA) have been inserted into this script questions about health perception, current and future WA (two years from now).

4. Emotional State

5. Job Satisfaction

   Two questions were also added to assess emotional state and job satisfaction. A Likert scale from 0 to 10 was used to answer all questions, and for the perception of health, current WA, future WA, and emotional state, the extremes represented respectively "very bad" and "great", and for satisfaction, 0 meant "totally dissatisfied" and 10 "totally satisfied".

6. Work demand The work demand was also evaluated based on the individual's perception of their work, in which they could refer to a greater physical or mental demand or the perception that their work involved both physical and mental demand, without any predominance.
