Extended arm shoulder lock escape
Also known as Straight Arm Shoulder Lock Escape — the canonical term used on this site.
Descriptive — long-form name for the straight-arm attack
Extended arm shoulder lock escape is the long-form descriptive name for the same defence, spelling out both the limb state the attack requires and the joint it actually threatens.
Etymology. The expanded phrasing exists because the short forms are ambiguous — “straight armlock” reads as an elbow attack, and on this site it now names one. Saying the shoulder explicitly is what the long form buys.
Mechanics. The distinction matters defensively because the shoulder warns differently from the elbow: rotational load at the shoulder gives a vaguer and later signal, so the defence has to be positional rather than reactive. Bent frames early, pummel the arm back to the mat side once captured, and rotate out rather than pull if it seats.
Cross-reference. “Straight armlock defence” is the shorter form. Full escape coverage on Straight Arm Shoulder Lock Escape.
