title: Analysis of cortical activation during three types of therapeutic activity.
abstract: [Purpose] The objective of this study was to investigate changes from resting of the evoked cortical activity when participants performed three levels of therapeutic activities. [Subjects and Methods] Twenty-five students participated in this study. Changes in the amplitude of 16 pairs of evoked potentials were compared for three different activities: adjunctive, enabling, and purposeful. Data were analyzed using descriptive statistics and one-way ANOVA. [Results] Significant differences were found among the selected three activities for the Alpha 1 waveform. The complexity hierarchy was confirmed by descriptive statistics, as well as analyses of the three brain regions: central position (motor) Beta 1; parietal lobes, Beta 2, and occipital lobes, Alpha 1. In each instance, purposeful activity was confirmed as the most complex activity, followed by enabling, and then adjunctive. [Conclusion] This study will provide rehabilitation professionals with valuable information regarding what type of activity they should choose for a correct level of therapeutic challenge when they work with patients to plan meaningful interventions.
