Repetitive strain from factory work

The same movement hundreds of times a shift has left your wrist, shoulder or back aching.

Why does the same job hurt more as the weeks go by?

Because your tissues do not get enough time to recover between repetitions. A packing, sorting or assembly task may ask the same wrist, shoulder or back to move hundreds of times in a shift. Ipoh has factories and workshops in places like Tasek, Menglembu and Jelapang, and the story is much the same in each.

At first it is a warm ache that fades overnight. Later it lingers into the morning, and finally it wakes you at night or weakens your grip. Earlier is much easier to settle than later.

What are the early signs I should not ignore?

Notice what changes at the end of a shift. These are common first signals.

  • A tight, burning forearm or wrist after the task.
  • Tingling in the fingers that eases when you shake your hand.
  • A shoulder that aches when you lift it to shoulder height.
  • A stiff neck or low back after standing or bending in one position.
  • Weaker grip, or dropping small items.

If two or more of these stay for more than a couple of weeks, have it assessed. Pain that comes with swelling, a hot red joint or weakness needs a doctor first.

What can I change at my station?

Start with the height and reach, because those are the easiest wins. Ask whether the bench can go up or down so your elbows stay by your sides and your wrists stay straight.

Bring the items you pick up most close to you. Use a footrest or an anti-fatigue mat if you stand, and swap sides or tasks when the line allows.

Your rest breaks matter. In the break, open and close your hands, roll your shoulders and bend backwards a little. Thirty seconds of this is worth more than scrolling on your phone with the same neck bend.

Is it only the wrist, or can the whole body be involved?

The whole chain can be involved. A sore wrist may come from a weak shoulder blade or a locked upper back. A low back that aches may be linked to how your hips and legs take the load.

That is why a physiotherapist looks at the whole movement, not only the painful spot. See our pages on wrist and hand pain, back pain and neck pain for what we check.

How does a physiotherapist help a factory worker?

We ask you to show the movement of your task, so the plan matches your real job. Then we treat the sore area, strengthen what is weak and teach small changes to your technique.

You also get short exercises that fit inside a rest break. For tips on setting up a work area, read about workplace ergonomics.

Can this be done at home after a long shift?

Yes. A home visit can be set for a rest day or after a shift, so you do not have to queue at a clinic on a tired evening. We work with what you have at home and what you can do on the line.

Our home physiotherapy page explains the first visit. Our Canning Garden centre is opening soon for those who prefer to come in; prices for home and centre differ and are quoted on WhatsApp.

Questions people ask

What is repetitive strain, in plain words?

It is pain that builds up when the same muscles and tendons do the same small movement thousands of times without enough rest. The tissue gets irritated bit by bit. It shows up in the wrist, forearm, shoulder, neck or back.

Should I tell my supervisor or just keep working?

Telling early is kinder to your body and your job. A small change, like a higher bench or a rotation between tasks, is easier to arrange at the start than after you need time off. Ask a doctor for a note if you need one.

Can I keep working while I have treatment?

In most cases yes, with changes to how you do the task and exercises for the weak or tight areas. Your doctor and employer decide on duties. We can describe, in writing, what movements to avoid or reduce so you can discuss it.

My hands go numb at night. Is that serious?

Night numbness in the thumb, index and middle fingers can point to a pinched nerve at the wrist. See a doctor to confirm. Physiotherapy can then help with positions, nerve exercises and workload.

Every body is different. For a diagnosis that fits you, see a registered physiotherapist or doctor, and seek urgent care for sudden weakness, numbness, chest pain or severe pain after a fall.
