Or are they so scared that they never change the status quo?

Abstract
Objective: To identify the effects of action observation training (AOT) on the walking ability of subjects with post-stroke hemiparesis.
Design: Randomized, single-blind, controlled pilot study.
Setting: Inpatient rehabilitation hospital.
Subjects: Twenty-one subjects with post-stroke hemiparesis were randomly allocated to either the experimental group (EG) or the control
group (CG), with 11 and 10 patients, respectively.
Interventions: The
subjects in the EG and CG watched video clips demonstrating four
functional walking tasks and showing different landscape
images, respectively. All subjects subsequently
performed the walking tasks (a total of 30 min, once a day, 3 times
weekly
for a 4-week period).
Main measures: 10-m walk test, figure-of-8 walk test (time and steps), dynamic gait index (DGI), and gait symmetry score (swing and stance
phases, and stride length) before and after the intervention.
Results: The changes
between the pre- and post-test values of the 10-m walk test (median
[interquartile range], -5.10 [-15.80–-1.60]
versus 0.00 [-6.60–4.06]), figure-of-8 walk test
(time: -3.50 [-12.60–-2.00] versus -1.25 [-4.98–0.25]; steps:-5.00
[-8.00–-2.00]
versus 0.00 [-3.25–0.25]), and DGI (4.00
[3.00–6.00] versus 1.00 [-4.00–3.00]) showed significant differences
between the
EG and CG (p < 0.05). In the EG, the 10-m walk test, time and steps of figure-of-8 walk test, DGI, and gait symmetry score in the stance
phase showed significant differences between pre- and post-test (p < 0.05).
Conclusions: The
findings suggest that AOT can be beneficial in enhancing walking ability
of patients with post-stroke hemiparesis, and
may be clinically feasible as a practical
adjunct to routine rehabilitation therapy. A power calculation on our
data showed
that 20 subjects in each group were required for
further definitive studies.
