Dear Biomch-L members:
It have been long observed and documented in certain degree that
the central neural system have the capability of adapting to compensate
for the loss of function in the pathological human locomotion. Even
though these adaptions lead to the abnormal kinematics and kinetics in the
locomotion, they should not be considered as pathological (D.A. Winter,
et al., 1990). Following are my questions:

1) How many such adaptions have been well defined in the human
walking and running gait?

2) How many such adaptions have been well defined in the upper
limbs and whole body related activities?

3) How can we always be able to distinguish the adaption from the
pathological change? As we all know, the patients with ankle instability
tend to move their hip more in order to keep their posture and balance.
If we observe the excessive motion in their hip joint during balance
exercise, can we simply ignore the possibility of overuse injury on their
hip joint soft tissues? This kind of injury may be a secondary injury
comparing to the primary injury. Is it possible for us to draw a limit
for the adaption?

I will post the summary as usual. Thank you in advance.
