A = uninvolved/uninjured/non-operative/non-surgical, dominant/preferred, right, stronger/better performing, or stance/support limb valueB = involved/injured/operative/reconstructed/surgical, non-dominant/non-preferred, left, weaker/lesser performing, or skill/kicking limb value* indicates the study used multiple indices, so appears more than once in this table
