Sensory & Motor blocks Assessment



Sensory block


Complete sensory block was considered when there was complete loss of sensation to pin prick.
Sensory block was graded as:
· Grade 0: Sharp pin felt
· Grade 1: Analgesia, dull sensation felt
· Grade 2: Anesthesia, no sensation felt

Motor block


Motor block assessment was done according to modified Bromage scale for upper extremities on a three point scale:
· Grade 0: No block-total arm and forearm flexion
(normal motor function with full flexion and extension of elbow, wrist and fingers.)
· Grade 1: Partial block,total forearm and partial arm flexion
·Grade 2: Almost complete block,inability to flex the arm and decreased ability to flex the forearm
·Grade 3: Total block,inability to flex both the arm and forearm

The motor block in the lower limbs can be assessed by the modified Bromage scale:

· Grade 0: free movement of legs and feet
· Grade 1: just able to flex knees with free movement of feet
· Grade 2: unable to flex knees but with free movement of feet
· Grade 3: unable to move legs or feet.


The motor block in the upper limbs can be assessed by the epidural scoring scale for arm movements (ESSAM) score:
hand grip (T1/ C8), wrist flexion (C8/C7), and elbow flexion (C6/ C5); four grades (0–3) based on the number of absent movements.
