This study had the following specific aims:
To complete the tasks, participants used an iPad with the test battery software and a stylus. The stylus was tethered to the tablet. Some tasks were completed with only the finger or stylus; some were completed with both input methods.
Investigators used a number of test battery tasks that examined various aspects of fine motor performance: (a) multidirectional pointing task, in which the participants selected targets of different sizes at various distances; (b) dragging task, in which a target was dragged from one position to another; (c) shape-tracing task; and (d) pinch-rotate task, in which a geometric object was pinched and rotated using the touchscreen to match an object presented on the screen.
Each session consisted of multiple trials of all four tasks. In the debrief session, participants were asked to complete short surveys about the tasks and the hardware. This was a small pilot test for the ISS portion of the study evaluating the software and hardware during HERA Campaign 1, mission 3.
Results indicate no significant decrements inflight during the six-month and one-year missions; however, small, but significant decrements were found in the days and weeks following landing, indicating the impact of the gravitational transition back to Earth. The Fine Motor Skills test battery software was released for public use through the NASA Technical Reporting process, and the app will soon be available on the Apple app store. The test battery can be used to measure fine motor decrements in elderly or diseased populations. The software may also prove beneficial in rehabilitation of fine motor skills in elderly patients, people with motor disorders, and patients with brain injuries.
