Hi Laila Ib

It sounds a very distressing situation for you and your mother.

After a stroke so many functions can be affected so I don't know what exactly is going on with your mother.

Here are some common scenarios:

  1. The stroke damaged the perception of pain or the regulation of that perception of pain so that now your mother experiences pain that where there is no real reason why she should be ie no tissue damage
  2. As above but she is actually having problems - the trouble is that the perception of pain is now exaggerated. This is quite common in stroke. Your mom probably has advanced osteoparthritis of her knees and the are sore when she weight bears or moves them. the experience of pain may now be way out of proportion to the state of her knees. With the loss of the increased inactivity after the stroke this can make the osteoarthritis worse so gets to be a vicious cycle.
  3. Your mother may not have a changes perception of pain. It might be that her arthritis has been aggravated by the induced inactivty. With the weakness (I take it your mother has severe weakness down one side of her body?) this can make affect the function of the knees and there is less protection of the arthritic joints. In which case she needs some help with the knees. Sometimes a combination non sterodal Wikipedia reference-linkanti-inflammatory drugs and active physiotherapy to improve the function of the joints and strength of the muscles that protect the knees
  4. Your mother may have either of the above but into addition to this she may have undergone some cognitive or personality change since the stroke. For example is she more prone to emotional outbursts or finds it harder to reason through things? In which case the screaming maybe because of the discomfort or she hates the effort required to do anything or she feels out of control or whatever. However it gets expressed this way - sort of a behaviour problem really. In which case the screaming may be get "reinforced" when the therapist gives in to the screaming and gives her a break.. At this point you really need an assessment by a clinical psychologist who can give some practical help with how to manage this.


There are a number of options here. First off you need to have the problem properly diagnosed. If the problem is due to 1) or 2) then there are a number of medications that may help your mother. These medications work on central nervous system. It may be that your mother needs to be seen by a pain team - a group of health professionals that take a whole approach when pain becomes a problem in itself.

Rather a long answer but you get the point - there can be lots of reasons and everyone presents somewhat differently. whatever I would advise you to get some specific help. Your mother is probably dreading physiotherapy which only makes matters worse.
