Description
OBJECTIVES:
Fine motor skills will be critical during long-duration space missions, particularly those skills needed to interact with technologies required in next-generation space vehicles, spacesuits, and habitats. They will be necessary for performing tasks in transit or on a planetary surface, such as information access, just-in-time training, subsystem maintenance, and medical treatment. Few, arguably no, studies have been completed in long-duration microgravity to investigate the type of functional fine motor performance required to interact with advanced technologies (e.g., touch technologies, gesture interfaces). There has also not been a complete, systematic study of fine motor performance to include different phases of microgravity adaptation, long-term microgravity, and the sensorimotor recovery period after transition to Earth gravity. In addition, the fine motor control studies conducted to date have not been conclusive regarding the effects of microgravity. The aim of this study was to determine the effects of long-duration microgravity and of different gravitational transitions on fine motor performance.

This study had the following specific aims:

  1. Determine the effects of long-duration microgravity on fine motor performance.
    1) How does fine motor performance in microgravity trend/vary over the duration of a year-long space mission?
    2) How does fine motor performance on orbit compare with that of a closely matched subject on Earth?
  2. Determine the effects of different gravitational transitions on fine motor performance.
    1) How does performance trend/vary before and after gravitational transitions, including the periods of early flight adaptation, and very early/near immediate postflight periods?

Human Research Program (HRP) Human Research Roadmap (HRR) Information
Crew health and performance is critical to successful human exploration beyond low Earth orbit. The Human Research Program (HRP) investigates and mitigates the highest risks to human health and performance, providing essential countermeasures and technologies for human space exploration. Risks include physiological and performance effects from hazards such as radiation, altered gravity, and hostile environments, as well as unique challenges in medical support, human factors, and behavioral health support. The HRP utilizes an Integrated Research Plan (IRP) to identify the approach and research activities planned to address these risks, which are assigned to specific Elements within the program. The Human Research Roadmap is the web-based tool for communicating the IRP content.

The Human Research Roadmap is located at: https://humanresearchroadmap.nasa.gov/
