Frozen Shoulder and Diabetes

Niel Asher Technique - Frozen Shoulder

 

What is the connection between frozen shoulder and diabetes? 

A frozen shoulder seems to result from the way the brain responds to inflammation around the long head of the biceps in the rotator interval. In some people, and we still don’t know why, the brain over-reacts to this inflammation by switching off groups of muscles and changing their dynamics.

We do know however, that frozen shoulder is much more common in diabetics. About 20% of diabetics are affected compared to around 5% of the general population. It is not clear why this should be the case but experimental studies have shown that the soft tissues of the shoulder are stiffer than normal.

Collagen

All muscle fibers are ‘packed’ within other tissue called parenchyma. This packing substance is made of collagen. Collagen helps to make up the elastic component of the skin and muscles (ex. as we get older our skin wrinkles as a result of decreased collagen production).

US doctors NA Friedman and MM LaBan published a paper in 1989 in which they put forward two theories as to why frozen shoulder is more common in those suffering with diabetes.

Diabetes and Frozen Shoulder - Theory 1

Because Type I diabetics are unable to regulate their blood sugar levels naturally, there are many times during the day that the sugar levels may be high, which can lead to an accumulation of sugar-alcohol in the tissues.

This sugar-alcohol is called sorbitol and it accumulates in the ‘ground substance’ of the connective tissues (collagen) where, because it has a higher osmotic pressure, it attracts water, making the tissues stiffer.

Diabetes and Frozen Shoulder - Theory 2

An alternative explanation has been put forward, whereby the properties of the collagen itself are attenuated.

It has been suggested that the collagen becomes embedded with excess sugar called glycogen. This ‘glycosylation’ of collagen leads to more bonds and bridges being formed at a molecular level between collagen molecules, thus changing the internal structure of the collagen. This means that enzymes cannot efficiently replace normal collagen wear and tear, and the tissues get stiffer.

Treatment

If you suffer with diabetes and begin to experience symptoms of a frozen shoulder, we strongly advise seeking attention as soon as possible. There are manual therapy techniques that are extremely effective for treating this condition, but early intervention can be important.

Whilst surgery is often recommended in severe cases, in our opinion, this should be considered as a last resort only.
