The first week back at the desk

Opening Trilogy 3. The Modern Body.

September is one of the most predictable times of year clinically. The summer ends, the diaries fill up again, people go back to full working weeks at their desks, and within a fortnight the lower back complaints begin to arrive. It happens every year, and we could almost set a calendar by it. By the second or third week of September the clinic schedule looks meaningfully different from August’s, and the most common phrase in the assessment notes is some version of “it was completely fine until I went back to work.”

There is a useful lesson hidden in that pattern. We are the same person who walked through August without back pain and the same person who has back pain in September. The difference is not in us. It is in the conditions our body has been asked to operate inside. August had walking, variability, frequent posture changes, lower cognitive load, more sleep, more recovery, less continuous sitting. September has long meetings, screen bound days, missed lunches, six hour stretches in the same chair, and the cognitive load that keeps people from noticing how long they have been still.

Lower back pain in September is rarely a back problem. It is a sitting problem with our back as the messenger.

This is the first issue of Trilogy 3. The Modern Body. Over the next six weeks we’ll look at how desk bound work writes itself onto our bodies, taking three of the most common presentations as the working examples: the lower back this week, the shoulder and upper back in two weeks, and chronic tightness despite stretching as the closing piece.

Case of the Week

Cases are composite portraits drawn from common presentations at Joint Space. They are not individual patient records.

A 39 year old came in during the second week of September describing a familiar ache across his lower back that had returned within days of his first full week back at his desk. He had spent August in Italy with his family, walking miles every day, swimming, sitting in cafés rather than meetings, eating slowly. His back had felt completely fine for the entire month. The moment the working week resumed, the ache came back with it.

He had been through this cycle before, in previous Septembers. He had assumed it was just something his body did. That he was ageing, or stiffening, or that something needed fixing. None of the previous assessments had explained it signicantly enough in a way that gave him anything to change.

The assessment took less than an hour. His hip flexor length was significantly reduced bilaterally. His glute activation on a single leg was visibly poor. His thoracic rotation was restricted, particularly on the dominant side. His movement variability through a working day was, by his own description, nearly zero. He sat down at 08:30 and often did not stand until lunch. His lower back itself was tender, modestly restricted, but the most healthy structure in the chain.

The plan was almost entirely about what surrounded the sitting rather than how he sat. He set a timer to stand and move for two minutes every 45 minutes, did a five minute morning sequence to wake up his hips, glutes and thoracic spine, and took a 20 minute walk after lunch. Alongside that, two Recovery Space sessions a week and one mobility session. Nothing about posture, ergonomics or chairs.

Within three weeks his back pain had reduced to manageable levels. Within six weeks it had gone. He had not reduced the amount of sitting; he had changed the conditions around it.
