Подскажите, пожалуйста, как может переводиться выражение "run the bases" в следующем контексте:

The ability to "run the bases" was assessed for three different ankle joint orthoses (12). They found
no difference between the no orthosis situation for this test and for the ALP and the Swede-0 orthoses. However, they found a reduction of the "run the bases" performance of 7% for the AirSeirmp orthosis.

Заранее большое спасибо!
