Are you sitting comfortably..? Changing position through the day
Positioning is not a once a day job. It is something that needs checking regularly to either put your joints into a new position or to reposition your limbs or trunk if they have moved out of the correct position.
People adopt a variety of positions to do everyday things and changing your position may help you to do other tasks more easily. A normal shoulder joint moves thousands of times in one day. However, if you are sitting for much of the day, this is possibly not the case and stiffness and sometimes pain can become a problem.
If you can move your arms, every hour try taking them up in the air, out to the side and circling them to help to keep them flexible. If you cannot move your arms, ask someone to put them in different positions at different times during the day. For instance, lying your arms out to the side on pillows with the elbows straight will give them a good stretch and help to keep them flexible. If your fingers tend to curl up, place them out straight for a while on a cushion.
The same thing applies if you can move your upper body; leaning forwards, backwards, side to side and twisting to look over each shoulder a few times every day may help to keep your upper body as strong and flexible as possible and relieve pressure on your bottom and stress in your spine.
You could achieve this by putting a pillow on a table in front of you and stretching your upper body and arms over this. This will give your back and shoulder joints a stretch and could be a comfortable position in which to rest.
It is important that you lean forwards by bending from the hips and not the spine. If you find your feet fall backwards in this position, supporting them on a couple of books may help.
Try a change of position. A rolled-up towel under the armpit can help to keep the shoulder from getting stiff if you cannot move your arm. If possible, move the arms into different positions during the day.
