I'm writing regarding the discussion on hamstrings which I highly doubt a
seasoned athlete will pull a hammy because of spurious activity. If a false
move could easily injure the athlete it would be so easy to have the athlete
just avoid that movement, but they can't because these are essential
movements that leading to the injury which has been waiting to happen.

But, having said this specific diagnosis of the problem must be identified
rather that pontificating about the role of Tr.Ab which may or may not be
related.

Knowing the mechanism of injury and correlating it to the following should
provide the information needed to treat this patient.

1st, is the Biceps fem., the Semi-memb., or Semi-tend. the injured muscle.
This can be tested by strength testing which is possible and not to
difficult to isolate medial from lateral HS's. See Kendall's muscle testing
book.

2 is this a distal or proximal HS injury. This can be determined by atleast
palpation.

If the lateral HS is injured it could also be a sciatic nerve injury or
better labeled a nueral tension problem. I have rarely seen a medial hs
injury and it is usually in a young adult where the mechanism of injury
matches a spotaneous stretch in a way that would injure the medial hs such
as slipping into a split type position.

Furthermore there could be problems with the lumbar spine causing injury to
the nerve roots as it exits the foramen. This is when spinal mobility
testing is important. It is not surprising to find in athletes (or anyone
else for that matter) hyper and hypomobile segments which contribute to this
problem.

And to make matters worse there probably are biomechanical imbalances of the
whole lower chain into the spine which may contribute to this spine
disorder.

I look forward to further discussion from the list on this matter.
