Development of the Movement Pattern Observation Tool (MPOT) – An observational tool to measure limb movements during elementary school recess
Background: The US Center for Disease Control estimates that only 24% of American elementary-aged children participate in the recommended 60 minutes of daily physical activity. As activity levels continue to decline for elementary-aged children, elementary schools should consider increasing movement opportunities within the school day. Activity-driven school days, where children can move their limbs freely, may increase performance in memory retention, behavioral impulse control, as well as increase bone density and muscle strength. Unstructured, outdoor play, referred to in this study as recess, may provide an opportunity for these brain, bone, and muscle-stimulating limb movements to be utilized. To date, no research has focused on whether the modern child actively uses limb movements during recess, nor to what degree. The purpose of this study was to develop a reliable assessment tool to observe and record limb movements (unilateral, bilateral, and contralateral movements) of elementary children during recess.
Methods: The Movement Pattern Observation Tool (MPOT) was developed to observe limb movement use during elementary school recess. This tool was developed in three phases: Identifying the movements observed in recess, using phase 1 observations to develop the tool, and determining the Interrater Reliability of the tool.
Results: Researchers used the observation method to identify specific unilateral, bilateral, and contralateral limb movements. The MPOT final form was accomplished through three revisions of multiple data samples. Interrater reliability was tested and approached excellent, being that excellent is above .90. The ICC of the master observer and observer 3 value was [.898 (95% CI .757-.957)], and ICC of the master observer and observer 2 was [.885 (95% CI .599-.967)].
Conclusions: The MPOT can help determine the percentage of children participating in limb movement activities versus the percentage of inactive children during recess. Moreover, the use of the MPOT may provide researchers with insight into whether the repetition of limb movements correlates strongly with memory retention, bone density, and muscle strength.
