P14.1 Klumpke paralysis due to birth injury
P14.3 Other brachial plexus birth injuries
PREFERRED PRACTICE PATTERN3
A 3-week-old infant is referred to outpatient physical therapy for right Erb palsy. The mother reports an uneventful pregnancy but prolonged and difficult delivery especially in getting the shoulder out of the birth canal. Upon examination, the infant presents with fisting of the left hand and physiologic flexion of the elbow typical of a newborn but the right arm is postured by the baby’s side. There is full passive range of motion (ROM) for the elbow, wrist, and hand and at least 90 degrees of right shoulder motions with the therapist deferring assessment above 90 degrees to prevent overstretching of the shoulder. There is active motion of the right upper trapezius but no active shoulder abduction, external rotation, or elbow or wrist extension. The therapist instructs the family on gentle passive ROM, dressing, positioning, and handling of the affected side and recommends weekly physical therapy.
