Table 1

Japanese Orthopedic Association score for cervical compressive myelopathy.

Dysfunction score

A. Motor function
 I. Fingers
  0 = unable to feed oneself with any tableware, including chopsticks, a spoon, or fork, and/or unable to fasten buttons of any size
  1 = can manage to feed oneself with a spoon and/or a fork but not with chopsticks
  2 = either chopstick feeding or writing is possible but not practical, and/or large buttons can be fastened
  3 = either chopstick feeding or writing is clumsy but practical, and/or cuff buttons can be fastened
  4 = normal
 II. Shoulder and elbow (evaluated by MMT score of the deltoid or biceps muscles, whichever is weaker)
  −2 = MMT ≤ 2
  −1 = MMT 3
  −0.5 = MMT 4
  0 = MMT 5
