School backpack and homework desk, the check to do at home

Schools reopened a month ago, and this is the time of year when parents turn up at the clinic with the same sentence: "he sits all crooked", "that backpack weighs a ton", "she says her neck hurts when she does her homework". In most cases there is nothing worrying: habits settled in during the first few weeks and, while they are still fresh, they take a few minutes to correct.

What I tell my patients is: don't turn it into a posture lesson. What you need is a practical check, done with your child one evening after dinner: a scale, the backpack emptied out on the table, and the homework chair. Ten minutes. Then do it again a week later, because these things drift back on their own.

1. The backpack: weigh it first, then empty it

Step on the scale holding the backpack, then without it: the difference is what your child carries every morning. The most widely used rule of thumb is to stay under 10-15% of body weight: 3-4.5 kg for a 30 kg child, 5-7.5 kg for a 50 kg teenager.

If you are over, the answer is not training: it's the contents. Tip it out on the table and go through it together. What usually turns up: the textbook for a subject that wasn't on the timetable, the litre-and-a-half water bottle filled at home when there is a drinking fountain at school, the spare notebook "just in case". Packing the bag the evening before with the timetable in front of you makes more difference than any exercise.

Then adjust it on their back. Both straps, tight enough that the backpack stays against the spine: the bottom should not drop below the iliac crest, the bony edge you can feel at the sides of the pelvis. A chest or waist strap, if there is one, shifts part of the load from the shoulders to the pelvis. The heaviest books go at the bottom and close to the back, not in the outside pocket.

A backpack is adjusted on the body, not hung off one shoulder.

2. The homework station: feet, elbows, eyes

Start with the feet. Sitting down, your child should have them flat on the floor, knees at about 90 degrees. If the feet dangle, you don't need a new chair: a small stool or a box of books will do. The pelvis goes to the back of the seat, not the edge.

Then the elbows. With the forearms resting on the table, the elbow angle should be around 90 degrees and the shoulders low and relaxed. If the shoulders creep up towards the ears, the table is too high: raise the child with a firm cushion on the seat and sort out the footrest.

Finally the eyes. With a tablet or laptop, the top edge of the screen goes at eye level, about an outstretched arm away, 50-70 cm. A laptop flat on the table forces them to look down for an hour: put it on a riser, with a separate keyboard if you have one. Notebook and book tilted slightly towards them, and the light coming from the side.

The table is adjusted to the child, not the child to the table.

3. Breaks matter more than perfect posture

This is the most underestimated part, and the one that weighs most. No position is wrong for five minutes and none is right for two hours: the spine needs changing loads to keep muscles and ligaments elastic.

The rule that works with children is simple: 25-30 minutes of homework, then 5 minutes standing up and away from the chair. Not on the phone while still seated: go and get a drink, carry something to another room, reach the arms overhead. At primary school, drop to 15-20 minutes of work at a time.

Look at how much they move over the whole day, too. An hour outdoors, a bike ride, sport twice a week do more for their back than any ergonomic chair.

The best position is always the next one.

When to see an osteopath

These checks are prevention, not a substitute for a professional assessment. It's worth booking an appointment when neck or back pain lasts more than two weeks, when it keeps coming back in the same spot or on the same side, when it wakes them at night or comes with tingling, or when your child avoids a movement or a sport they used to enjoy.

At the first visit, at the clinic in Pasiano di Pordenone, we assess mobility, foot loading and daily habits together, and talk through what to change at home. Osteopathy works on joint mobility and tissue tension: at school age it is mostly about supporting growth.
