Approximately 24% of stroke survivors experience co-occurring aphasia and hemiparesis. These individuals typically attend back-to-back therapy sessions. However, sequentially scheduled therapy may trigger physical and mental fatigue and have an adverse impact on treatment outcomes. The current study tested a hypothesis that exerting less effort during a therapy session would reduce overall fatigue and enhance functional recovery. Two stroke survivors chronically challenged by non-fluent aphasia and right hemiparesis sequentially completed verbal naming and upper-limb tasks on their home computers. The level of cognitive-linguistic effort in speech/language practice was manipulated by presenting verbal naming tasks in two conditions: Decreasing cues (i.e., most-to-least support for word retrieval), and Increasing cues (i.e., least-to-most support). The participants completed the same upper-limb exercises throughout the study periods. Both individuals showed a statistically significant advantage of decreasing cues over increasing cues in word retrieval during the practice period, but not at the end of the practice period or thereafter. The participant with moderate aphasia and hemiparesis achieved clinically meaningful gains in upper-limb functions following the decreasing cues condition, but not after the increasing cues condition. Preliminary findings from the current study suggest a positive impact of decreasing cues in the context of multidisciplinary stroke rehabilitation.
