Hi,

In general i agree with the above.

However if extension is required, then it should be able to be obtained if at all possible.

Perhaps the problem lies in a motor control issue where extension is not controlled properly and so a change in motor pattern might be helpful.

I have used this on people who had pain standing in erect neutral but a change in muscle usage and patterning into extension resulted in being able to hang washing on a line above head height without pain.

Shirley Sahrmann has a good but difficult to read textbook on movement impairment syndromes and Peter O'Sullivan has done some work in this area as well.

Good luck!
