Elaysian
The Elaysians are a humanoid civilization native to a low-gravity planet.
The Elaysian physique and neural motor cortex is adapted to cope with a low gravity; on their homeworld they are virtually able to "fly". When exposed to Earth-normal gravity environments they need physical support to function. The type of support varies but includes wearing an external skeleton with integrated servomotors which helps by supporting the person's own skeleton. Early exoskeletons were unsuccessful, only allowed to be used for short-periods of time, however, by 2407, Starfleet Medical had made serious advances, now the exoskeleton could be used indefinitely without any lasting effects.
Only a handful of Elaysians have ever left their planet, even fewer have ever served in Starfleet.
