Space walk
From Halopedia, the Halo wiki
Space Walk is a condition that occurs to UNSC personnel that spend too much time in microgravity. It is likely that their legs become unaccustomed to holding their body weight due to muscle mass lost during extended periods of free floating. As a result, when they return to an atmosphere with stable gravity they have a strange lope to their walk. This is called "space walk" by crewmen.First mentioned in Halo: The Fall Of Reach when introducing CPO Mendez.
Recent developments in Gravity Plating may wipe out this condition, as humans will spend less time in microgravity.
NOTE: This term is only a nickname for Muscular Atrophy, an anatomical pathology.
