Back pain at work: how to improve your posture at the computer

Spending long hours at the computer is associated with an increased risk of back pain and other musculoskeletal complaints. In predominantly sedentary professions, such as technology, office or administrative jobs, posture and prolonged static positions play an important role in physical health, productivity and daily well-being.

Small postural deviations, when maintained over time, can contribute to tissue overload, muscle fatigue, decreased functional capacity and, in some cases, the development of persistent pain. Adopting preventive strategies in the workplace can help reduce these risks.

Strategies to prevent back pain at work

Here are seven practical guidelines, often used in clinical and ergonomic contexts, which can help improve posture and reduce back strain when working at the computer.

• Height and distance from the monitor: The top of the screen should be at approximately eye level, avoiding excessive tilting of the head up or down. The distance to the screen tends to be most comfortable when it is about an arm's length away, approximately 50 to 70 cm. When using laptops, the use of a raised stand and an external keyboard can help reduce less favourable postural compensations.
• Foot support and positioning of the pelvis: The feet should maintain complete contact with the floor or a suitable support. Avoiding crossing the legs can help reduce asymmetries in the pelvis and lumbar spine. A neutral position of the pelvis favours better alignment of the spine and a more balanced distribution of loads.
• Chair and workstation: Chairs with adjustable lumbar support and backrests that respect the natural curvatures of the spine can facilitate a more comfortable posture. The height of the desk should allow the elbows to be close to the torso, at an approximate angle of 90 degrees, and the forearms to be supported. Whenever possible, alternating between sitting and standing can help reduce prolonged exposure to a single posture.
• Pactive absences and postural variation: Breaking up the sitting posture every 45 to 60 minutes, even briefly, can be useful. Small movements, such as walking, gentle stretching or mobilising the thoracic spine and shoulders, help to reduce joint stiffness and stimulate circulation.
• Keyboard, mouse and accessories: The keyboard should allow the wrists to remain in a neutral position, avoiding excessive flexion or extension. The mouse should be close to the body and at the same height as the keyboard, reducing the need to raise or move the shoulder. Ergonomic accessories can be useful, but they are no substitute for proper overall postural organisation.
• Strengthening and mobility outside the workplace: The ability to maintain a prolonged sitting posture is related to the strength and control of the trunk muscles. Exercises aimed at strengthening the colour, as well as mobility of the thoracic spine and stretching of the anterior chest muscles, can help to counteract maintained postural patterns. Approaches such as Clinical Pilates are often used in this context, as they integrate movement control, strength and body awareness.
• Stress and psychosocial factors: O stress prolonged can be associated with increased muscle tension, changes in breathing patterns and greater physical fatigue. Strategies for managing stress, Regular breaks and attention to psychological well-being can positively influence the way the body responds to the demands of daily work.

Adopting these strategies can help to better manage the loads that the spine is subjected to throughout the working day. When persistent complaints, frequent stiffness or functional limitations arise, an individualised assessment by a Physiotherapist or Osteopath can help identify the factors involved and guide appropriate interventions.

In the approach to back pain, the focus is not just on where the discomfort is felt, but on how the body moves, bears loads and responds to the demands of everyday life. This perspective allows us to better understand the mechanisms that may be contributing to the maintenance of symptoms.

At Integrativa, the process begins with an individualised assessment, where aspects such as posture, spinal mobility, movement control, strength, breathing patterns and work or daily life habits are analysed. Based on this assessment, the intervention can integrate different areas in a complementary way:

• Physiotherapy, The aim is to improve mobility, movement control, strength and load tolerance, using targeted exercise and functional strategies adjusted to daily and professional activities.
• Osteopathy, This is aimed at assessing and optimising the mobility of tissues, joints and fasciae, helping to reduce excessive tension and improve the overall organisation of movement.
• Clinical Pilates and Reformer, It is used as a tool for movement re-education and muscle strengthening of the colour, mobility of the spine and development of body awareness, with safe progression adapted to each person.

This integrative approach seeks to reduce mechanical overload, improve movement efficiency and support the body's adaptation to the demands of work and everyday life, while always respecting individual characteristics, context and goals.
