Grades of ROM

Grade 5 (Normal)

Full ROM anti-gravity and able to maintain break test position against MAXIMAL resistance

Grade 4 (Good)

Full ROM anti-gravity but yields with maximal resistance at break test position or can only maintain break test position with MODERATE resistance

Grade 3+ (Fair+)

Full ROM anti-gravity and able to maintain break test position with MILD resistance

Grade 3 (Fair)

Full ROM anti-gravity but cannot maintain break test position with ANY resistance

Grade 2+ (Poor+)

Cannot complete full ROM anti-gravity but can complete OVER HALF of the ROM anti-gravity and FULL ROM gravity eliminated

Grade 2 (Poor)

LESS THAN HALF ROM anti-gravity but FULL ROM gravity eliminated

Grade 2- (Poor-)

Cannot complete full ROM gravity eliminated; PARTIAL ROM ONLY in gravity eliminated position

Grade 1 (Trace)

NO ACTIVE MOVEMENT of joint but able to PALPATE muscle contraction

Grade 0 (Absent)

Completely inactive; NO MM CONTRACTION OR MOVEMENT
