The effect of ergonomics orientation and motor control exercises in patients with work-related upper extremity disorders (WRUED)

INTERVENTION: A group will receive ergonomics orientation and another will receive ergonomics orientation and motor control training for movement re‐education. Both groups will be followed‐up for 4 weeks and will be reassessed after 2 weeks as well as on the last day of follow‐up so as to verify the effects of the ergonomics orientation an of the ergonomics orientation plus the motor control training in terms of pain, movements and work ability. The ergonomics orientation and motor control training group will do personalised therapeutic exercises aiming to increase strength, muscular length and motor control, according to the diagnosis of imperfect movements. CONDITION: Work‐related upper extremity disorders (WRUED) ; Injury, Occupational Diseases, Poisoning PRIMARY OUTCOME: Pain, assessed through the Visual Analogue Pain Scale (VAS) SECONDARY OUTCOME: Work Ability Index validated in Brazil INCLUSION CRITERIA: 1. Patients, either sex, aged between 20 and 55, with specific or non specific WRUED who complain about pain in the cervical area, shoulders, elbow, forearm, wrist and hands and have difficulty to make work‐related as well as daily life movements for at least 6 months. 2. Patients who have agreed to interrupt the traditional physiotherapeutic treatment and to participate in this study for 4 weeks. 3. Patients who have painless movement in at least 60% of the normal range of movement of the glenohumeral joint for flexion and rotation.
