| Purpose | Determining muscle tone in newborns |
Arm recoil is a neurological examination of neonate for detecting the muscle tone.[1][2]
Procedure
The baby is placed supine, with forearm flexed at elbow. The elbow (forearm) is extended by pulling the hand; then released.[3]
Observation
How quickly the forearm returns to flexed original position and the amount of flexion will designate a score.[1]
- Grade 0: Arms remain extended 180 degrees or abnormal movements begin
- Grade 1: Minimal flexion, 140-180 degrees
- Grade 2: Slight flexion, 110-140 degrees
- Grade 3: Moderate flexion, 90-110 degrees
- Grade 4: Quick return to full flexion, less than 90 degrees
Conclusions
The greater the tone development (flexor tone), the brisker the recoil will be.[1] This correlates to more advanced gestational age on the Ballard Scale.[4]
Leg recoil can be assessed following the same principle.[5]
