Purpose: The objectives of this study were to quantitatively analyze the reaction patterns of ataxia and Parkinson's disease cases that are cognitively harmless and to examine the characteristics of pathological reactions, such as ataxia, rigidity, and motor control, compared to the patterns of a healthy subject.Methods: An eye–hand coordination pointing with pencil test (EHCPPT) app was developed that requires patients to tap a bullseye target with a pencil for screening testing. This app is intended to be used during regular check-ups of the elderly to help them maintain their home lifestyle through self-management of health. The EHCPPT consists of two tasks, both of which require the patient to tap a bullseye target as a test of eye–hand coordination in response to a stimulus sound. In one task, the sound is repeated rhythmically; in the other, it is generated irregularly and infrequently. The EHCPPT app is based on the “oddball paradigm” experimental design and can be administered in just a few minutes to measure the time lag between the sounds and taps as well as the distance between the target and tapped locations automatically.Results: The data generated when the app was used by a healthy subject, an ataxia patient, and a patient with Parkinson's disease were analyzed. In each case, the data exhibited a distinctive pattern.Conclusion: The EHCPPT app is simple and fast and shows potential as a screening test.

Aim: To clarify the characteristics of desktop dual tasks that cause dorsolateral prefrontal cortex (DLPFC) activation. Methods: Subjects (29 young adults and 22 middle-aged adults) performed three different combinations of dual tasks composed of a pencil and paper task (copying numbers or calculation) and a hand-shape changing task (in response to visual hints or self judgment). We measured brain activation using near-infrared spectroscopy. Results: Right DLPFC activation was significantly higher for the simplest dual task than the complex dual task with the younger group, whereas there was no significant difference between tasks with the middle-aged group. Task performance was higher in the younger group than the middle-aged group, whereas there was no difference in brain activation between the two age groups. Conclusion: A dual task including two of each task performed automatically could be used for training frontal lobe functions, and the difficulty level should be adjusted depending on age.
