Gait Rehab

" Rehabilitation of gait in PSP should also include oculomotor
training because the ability to control eye movements is directly
related to the control of gait and safe ambulation. Vision plays a
critical role in the control of locomotion because it provides
input for anticipatory reactions of the body in response to
constraints of the environment. Anticipatory saccades occur
normally in situations that involve changing the direction of
walking17 or avoiding obstacles.18 When downward saccades are not
frequently generated during obstacle avoidance tasks, there is an
increase in the risk for falling. Di Fabio et al19 reported that
elderly people at a high risk for falling generated fewer saccades
than their low-risk counterparts during activities involving
stepping over obstacles. In addition, foot clearance trajectories
were asymmetric in the high-risk group, with the lag foot
trajectory being significantly lower than the lead foot trajectory.
Similar behavior has been observed in patients with PSP during
stair-climbing activities. Di Fabio et al20 recently reported that
patients with severe oculomotor limitations had a lower lag foot
trajectory than those with mild oculomotor limitations. "
Eye movements:

" The content of the eye movement program was as follows: First, a
picture card was shown to the patient, and then mixed with 20 other
cards and spread face up on the desk. The patient was instructed to
find that one card. This task was repeated approximately 20 times.
Second, the therapist moved a baton slowly while drawing curves and
the patient was instructed to keep his or her gaze fixed on the tip
of the baton. In this task, the distance between the baton and the
patient was maintained at approximately 1 m and the task was
performed for approximately five minutes. Third, the patient was
instructed to shake his or her head laterally as quickly as
possible and a letter card with letters written upside down was
presented to the patient to read. This task was repeated
approximately 10 times. Fourth, the therapist moved a baton slowly
from a point approximately 5 cm away from the patient to a point
approximately 50 cm away and the patient was instructed to keep his
or her eyes on the baton. This task was performed for approximately
five minutes. The experimental group underwent eye movement
training while the control group underwent gait training for 20
minutes per session, five times per week for six months in
total."
