Starting to feel a bit self conscience that I am the only person raising questions on here....
Anyway, I am using one of the ladies that comes to my classes to practice the screening. She had already been doing the 4-sign a bit from doing it in the class and after a class a couple of weeks ago I quickly checked her leg length and did the downings an 4-sign screen on her. When I did it her leg length passed and she failed the right side and passed on the left of downings. I just did a full screen on her this afternoon and this time her leg length was different and the left failed and right passed downings (so the other way round). We did the leg press and did a rescreen. This time her right failed and her left passed only on medial rotation. I was confused and I screened the right again, this time it passed on the medial rotation but she said that when it passed she felt a click and when it failed she didn't feel a click. Can anyone tell me what has happened?
Another point of interest was that when we looked at her the first time round we discussed that she always runs round the park in one direction so we discused that she should mix it up a bit. She has been doing this so I wonder why this would have caused a shift from the sides that pass the downings test?
No problem, guys use the forum when they need to, so its all good.
The pelvis can 'swap sides' while it is adapting, so its not unusual, give it a few weeks to get a pattern. meanwhile manage what you can measure. yes you are rightb the track work, moving round one way can cause it too. dont worry too much about the clicking, its not been shown to mean anything.
you have started to stumble upon a problem explaining Downings test. In reality, the original and most obvious explanation for the mechanisms of the test turns out to be incorrect. This was shown in cases of advanced ankylosing spondylitis in which they sacroiliac joints were totally fused solid and cannot move at all. Performing the Downings test however still permitted leg length changes. Further analysis of data showed that the test actually indicates problems at the thoraco lumbar junction. It seems that the hip rotations pull on the psoas muscle which has its origins at the top of the lumbar spine. A whole new paradigm has now to be considered!
