Is this part of the reason stroke survivors don't walk very straight? Is your doctor treating the root cause - anxiety? Or doing nothing at all and assuming your PT will take care of your walking problems?

People experiencing anxiety and inhibition have more activity in the
right side of the brain, causing them to walk in a leftward trajectory.
New
research led by Dr Mario Weick of the School of Psychology at the
University of Kent has for the first time linked the activation of the
brain’s two hemispheres with lateral shifts in people’s walking
trajectories.
In a study aimed at establishing why individuals
display a tendency to allocate attention unequally across space, people
were blindfolded and asked to walk in a straight line across a room
towards a previously seen target.
The researchers found evidence
that blindfolded individuals who displayed inhibition or anxiety were
prone to walk to the left, indicating greater activation in the right
hemisphere of the brain.
The research indicates that the brain’s
two hemispheres are associated with different motivational systems.
These relate on the right side to inhibition and on the left to
approach.
This is the first time researchers have established a
clear link between inhibition and activation in the right side of the
brain.
The findings may have implications for the treatment of
unilateral neglect, which is a condition caused by a lack of awareness
of one side of space. In particular, individuals suffering from
right-sided neglect may benefit from interventions to reduce anxiety.
