Study Finds Ergonomic Office Upgrades Do Little to Ease Work-Related Arm, Neck and Shoulder Pain

A team at the University of Technology Sydney has gone looking for evidence that the ergonomic chair, the sit-stand desk and the specialized keyboard actually ease the aches of office work, and what they found was thin. Their review pulled together 20 trials involving more than 2,400 people who had work-related complaints in the arms, neck or shoulders.

The researchers compared workers who got ergonomic interventions against those who got nothing, or who received what is described as usual care: medical advice, discussion or counseling. The interventions included specially designed furniture and devices, among them chairs, sit-stand desks, keyboards and computer mice. Measured against the comparison groups, they showed little to no effect on pain, on function, on quality of life, or on how often workers took sick leave.

The equipment also lost out to a different approach. Ergonomic setups were less effective than posture-correcting exercises at treating pain or discomfort, though the two used together may bring short-term relief.

Lead author Dr. Poonam Mehta was careful about how far the evidence goes. In a news release she said the certainty ranges from low to moderate, which she called a clear signal that the case for these interventions is weaker than many people assume. She added that, on current evidence, these measures alone should not be expected to reduce pain or sick leave in the short term, and that employers may want to weigh that against the cost.

The cost is not small. According to Mordor Intelligence, the market for ergonomic office furniture is valued at $16.5 billion and is projected to approach $23 billion by 2031.

The review does leave some room for the equipment. Ergonomic setups may offer small benefits for specific conditions, such as rotator cuff injuries in the shoulder from repeated lifting. One study in the review suggested ergonomic treatment may reduce functional disability better than mobilization, strength and endurance training. But studies of people with carpal tunnel syndrome, the wrist condition tied to frequent mouse-clicking, did not find reduced pain from ergonomic keyboards or mice. Some results pointed to improved quality of life, though the team has limited confidence in that because the findings were mixed.

The conclusions cut against a long-standing argument. For decades, ergonomics experts have held that bad desk setups can lead to poor posture, aches and so-called tech neck, with consequences for employees and employers alike. Jonathan Puleio, a board-certified ergonomist and global vice president of Humanscale Consulting, previously told The Post that the long-term cost of poor ergonomics far exceeds the upfront cost of proper design.

This review challenges that position, and suggests offices reconsider spending on ergonomic tools and costly refurnishing. What it does not do is settle the question for every worker or every condition. The open matter is whether better trials, especially on specific injuries, will firm up the modest signals the researchers found.
