**This is a very interesting point that you have made. Is there any studies
whereby they have shown athletes returning to a sport after prolonged rest,
and play with comparable skill within a short time?? I play competitive
basketball regularly (actually, it is the 3rd best competition in Brisbane,
Australia), and I know that the first few games of the season that people
play are usually pretty awful until they really get back into trainning
again. It would be interesting to see how long it takes for them to return
to normal.

**There is a lot of difference between high level or amateur athletes and
patients in the clinic, pain been the most important. As we know, pain can
inhibit muscle contraction, and I speculate this as been the main reason why
the TrAb and Multif does not work. HOwever, further research will be needed,
especially in the observation of these muscles in normal people. I believe
this is different to not playing sport for a long time, and returning to
playing again. Therefore, I believe that muscle re-education is still very
important in the whole frame work of patient management.
