The purpose of this study was to determine whether chronometry is
appropriate for monitoring engagement in mental practice by comparing the time
taken for people with chronic stroke to mentally and physically practice five
tasks. METHOD: Eighteen stroke participants mentally and physically rehearsed
each task. Time was recorded for each of the three trials per task. RESULTS:
Participants required significantly more time to physically practice than to
mentally practice tasks (all p < .05). A significantly greater amount of time for
mental practice of the more-affected arm than for the less-affected arm was also
observed (p < .01). CONCLUSION: Because there was no agreement between the time
taken to mentally and physically practice the tasks, chronometry does not appear
to be valid for monitoring mental practice in this population.
