  For humans accustomed to 1-G environments on Earth, microgravity conditions
in orbit and on celestial bodies with lower gravitational field, such as the
Moon, can be physiologically compromising. Of these, motor and fine-dexterity
tasks involving the extremities, particularly in locomotion, grasp and release,
are influenced becoming delayed and placing greater force demands. The authors
hereby propose incorporating this same technological innovation into loading
suits designed for use in orbit or celestial environment. Current prosthetic
systems use electromyography (EMG)-based techniques for creating functional
sensorimotor platforms. This model sustains a sensorimotor platform for
prosthesis users. However, several limitations in practical use and signal
detection have been identified in these systems. Accelerometer-based
sensorimotor systems have been suggested to overcome these limitations but only
proof-of-concept has been demonstrated. Our group previously suggested the
combined application of prosthetic accelerometers in loading suits and EMGs for
input signal detection, quantification, and predictive output modelling
necessary for improved motion adjustments under microgravity conditions. It is
anticipated this technology can enhance tasks such as repairs or construction
or perhaps in recreational design when considering commercial and private human
access to space. The incorporation of a prosthetic biomechanical sensorimotor
system in loading suits to enhance locomotion under microgravity conditions are
conceivable; however, demonstration of a proof-of-concept is required before
implementation.
