Space Physiology and Technology: Adaptations, Countermeasures, and Opportunities for Wearable Systems

Area of Science:

• Space Medicine
• Biomedical Engineering
• Human Physiology

Background:

• Spaceflight presents unique physiological challenges, necessitating effective countermeasures for astronaut health.
• The musculoskeletal system is particularly vulnerable to the space environment, with bone and muscle adaptations impacting astronaut well-being.

Purpose of the Study:

• To review the impact of space on the musculoskeletal system.
• To explore wearable sensing and robotic technologies as advanced countermeasures for space missions.
• To discuss the terrestrial applications of these emerging technologies.

Main Methods:

• This narrative review synthesizes current research on space-related musculoskeletal adaptations.
• It evaluates existing countermeasures and their limitations.
• It proposes wearable sensing and robotic systems as novel solutions.

Main Results:

• Current countermeasures (e.g., exercise, pharmaceuticals) are partially effective, bulky, and resource-intensive for long-duration space missions.
• Wearable systems (sensor-integrated suits, soft exoskeletons) offer real-time monitoring and tailored exercise protocols.
• These systems are lightweight, modular, and suitable for confined spacecraft environments.

Conclusions:

• Wearable technologies represent a significant advancement over current space countermeasures.
• These systems have the potential to support rehabilitation, assist aging populations, and enhance physical performance on Earth.
• Integration of advanced materials and intelligent control is key to realizing the full potential of these technologies.
