What is the MMT grading scale for shoulder scaption?

What is the MMT grading scale for shoulder scaption?

• A. 0 = no contraction or movement, 1 = no movement but contraction, 2 = ROM at 90 degrees, 3 = partial ROM above 90 degrees, 4 = hold position w/ mod resistance, 5 = hold position w/ max resistance
• B. 0-5 scale but only holds with gravity
• C. 1-5 scale with 0 indicating full ROM
• D. 0 indicates full strength; 5 indicates no contraction

Answer: (A)

Shoulder scaption strength is assessed using the standard 0–5 manual muscle testing scale. The progression reflects increasing muscle activity and functional effort: zero means no contraction; a trace contraction means the muscle fires but there’s no movement; movement through the available range with gravity eliminated corresponds to a grade of 2; movement through the full available range against gravity corresponds to a grade of 3; holding the position against some resistance is grade 4; and holding the position against maximal resistance is grade 5. The described option follows this familiar sequence from no contraction to maximal resistance, which is why it aligns best with how MMT is taught for scapular-plane elevation (scaption). Other choices misstate aspects of the scale, such as what zero or five represents or how gravity influences the grading.
