Most people look at this and focus on the timelines. 9 months, 12 months, 2 years. Nice and tidy. Real patients donât follow that.
What matters more is what you actually see.
Adhesive capsulitis isnât just a âstiff shoulder.â Itâs a shoulder where movement is limited whether the patient tries⊠or you try. Active range is reduced, and passive range is reduced as well. Thatâs one of the key clinical signs.
If they canât lift it, but you can move it further, youâre thinking along a different line. If both are restricted â especially external rotation â adhesive capsulitis moves higher up your list.
Now, risk factors.
This doesnât just show up randomly. There are patterns. Diabetes is a big one. Thyroid disorders also come up regularly. Previous shoulder injury or a period of reduced use can trigger it. And then thereâs age â most commonly between 40â60.
Youâll also see it more in females, and menopause likely plays a role here. Hormonal changes, particularly the drop in oestrogen, are thought to influence connective tissue behaviour and inflammatory responses. That can make the capsule more susceptible to thickening and stiffness. Itâs not the only reason, but itâs part of the picture.
The inflammation point in this graphic is only part of the story. Early on, yes, there may be an inflammatory component. As it progresses, youâre dealing more with capsular thickening and reduced joint capacity. So itâs not just something that needs âcalming down.â
And the stages? Freezing, frozen, thawing. Useful as a rough guide, but donât treat it like a schedule. Patients donât move through this in a straight line.
Management isnât about forcing range back. Itâs about working within tolerance, keeping the shoulder moving, and reducing sensitivity so the patient can actually use it again. Sometimes injections help, sometimes they donât. Thereâs no one-size approach.
Bottom line:
If it doesnât move when they try⊠and it doesnât move when you try⊠pay attention.
