An alternative or variant form of autokinesis, referring to self-initiated or spontaneous movement.
From Greek 'auto-' (self) + 'kinesis' (movement), with an alternate suffix '-y' instead of the more common '-sis'. Variant terminology in scientific nomenclature.
Scientific terminology is messier than most people realize—'autokinesy' and 'autokinesis' competed for dominance but '-esis' won because it sounds more authoritative in Latin, not because it's more accurate.
