Occupational therapy is based on the concept of enhancing motor, cognitive, sensory, and psycho-social performance through the utilization of purposeful activities. Purposeful activities are doing processes directed toward a planned or hypothesized end result, and can be naturalistic, simulated, or imagery-based (Nelson & Peterson, · 1989). This study compared the effects of a material-based occupation, imagery-based occupation, and rote exercise on the quality and duration of maintaining prone extension in children aged three to nine.· The quality of maintaining the posture was analyzed using the prone extension postural test (Gregory-Flock & Yerxa, 1984). Duration of prone extension for each child was measured in seconds.

An analysis of variance indicated that the difference between conditions for the quality variable was not statistically significant (p= .1117). The duration variable yielded differences which approached significance (p=.076).
