Poor postures are often identified as the main cause of muscle and joint pain. However, Martín Barra, a researcher in the Department of Physiotherapy, states in an article recently published in The Conversation, that it is not the posture itself that causes the pain, but the time spent in it without moving.
"Any posture held for a long time can cause discomfort, even one that many would consider ideal”, says the expert. As Barra explained, the search for an ideal posture has historical roots. "Since the 19th century, models for posture have been designed based on anatomical misconceptions, such as the one that proposed rigid vertical alignment to minimise muscle strain. Today we know that this posture can be detrimental to joints, such as the knees," he added.
The upright posture was considered favourable not only socially but also medically, as it was linked to the prevention of diseases such as tuberculosis and to the correct development of children. However, subsequent studies disproved these beliefs and led experts to question whether there really is such a thing as an ideal position. In this regard, researcher Martín Barra states that the idea of perfect posture is a myth because "the standard posture used to assess body alignment does not take into account the natural variations between individuals. What is considered bad posture in a person can simply be their natural posture,” he says.
As Barra reveals, the problem lies in immobility rather than posture, so the key to preventing musculoskeletal pain commonly associated with posture is to vary posture frequently. “The best posture is to get moving. Changing positions, stretching and not staying still are the best strategies for taking care of our postural health,” advises the physiotherapist and researcher.
