Does your hospital/clinic have 120 videos of each type of action observation you want to recover?
Why not, they've had 20 years to create them?

The most efficient way to acquire motor skills may be through
physical practice. Nevertheless, it has also been shown that action
observation may improve motor performance. The aim of the present pilot
study was to examine a potential action observation paradigm used to (1)
capture the superior performance of expert athletes and (2) capture the
underlying neural mechanisms of successful action observation in
relation to task experience. We used functional magnetic resonance
imaging to measure regional blood flow while presenting videos of a
hockey player shooting a puck toward a hockey goal. The videos (a total
of 120) where stopped at different time frames with different amount of
information provided, creating a paradigm with three different levels of
difficulty to decide the fate of a shot. Since this was only a pilot
study, we first tested the paradigm behaviorally on six elite expert
hockey players, five intermediate players, and six non-hockey playing
controls. The results showed that expert hockey players were
significantly (
p < 0.05) more accurate on deciding the fate of
the action compared to the others. Thus, it appears as if the paradigm
can capture superior performance of expert athletes (aim 1). We then
tested three of the hockey players and three of the controls on the same
paradigm in the MRI scanner to investigate the underlying neural
mechanisms of successful action anticipation. The imaging results showed
that when expert hockey players observed and correctly anticipated
situations, they recruited motor and temporal regions of the brain.
Novices, on the other hand, relied on visual regions during observation
and prefrontal regions during action decision. Thus, the results from
the imaging data suggest that different networks of the brain are
recruited depending on task experience (aim 2). In conclusion, depending
on the level of motor skill of the observer, when correctly
anticipating actions different neural systems will be recruited.
