DIAGNOSING ERB’S PALSY
Erb’s palsy is diagnosed by a thorough physical examination and medical history. An affected baby may hold its affected arm close to the body with the elbow pronated. In additional to a routine physical examination, some doctors may perform special imaging and diagnostic studies such as a nerve conduction study or magnetic resonance imaging (MRI).

CLINICAL ASSESSMENT
U.E is flail & dangling Look for other extremities U.R: arm held in IR,add, active abd
not possible, elbow extended forearm pronated, thumb flexed.
Complete paralysis- vasomotor impairment, pale & marble like color
Horner’s sign Associated # [clavicle, humerus]

DIFFERENTIAL DIAGNOSIS
Fracture Pseudoparalysis Congenital Varicella of the Upper
Limb Cerebral Palsy (Monoplegia) Intrauterine Upper-Limb Nerve
Compression by the Umbilical Cord or Amniotic Bands
Intrauterine Maladaption Palsy

Protective phase Initial rest period of 7-10 days – to
allow for reduction of hemorrhage & edema around the traumatized nerves
No ROM or other interventions are initiated
The involved UL is positioned across the abdomen or aeroplane position.
Avoid lying on the involved limb Positioning, splinting, kinesiotapping,
gentle massage therapy

CONSERVATIVE MANAGEMENT
PHYSIOTHERAPY – cornerstone of conservative mngt.
Maintain – PROM, Supple of muscle. Improve Muscle strength Stretch muscle groups to prevent contracture. Facilitates normal movement patterns while
inhibiting substitutions. Sensory Awareness Positioning (abd, ER, F/A flexion, wrist ex.) Splinting Kinesiotapping Electrical Stimulation

splinting
-Resting night splints – prevent wrist & finger F contracture
-Wrist cock-up – maintain neutral wrist alignment (Klumpke’s Paralysis)
-Statue of liberty splint – prevent Add & IR contracture

SURGICAL MANAGEMENT If there is no change over the first 3 to 6 If there is no change over the first 3 to 6
months, doctors may suggest exploratory months, doctors may suggest exploratory surgery on the nerves to improve the potential surgery on the nerves to improve the potential outcome. Nerve surgery will not restore outcome. Nerve surgery will not restore normal function, and is usually not helpful for normal function, and is usually not helpful for older infants. Because nerves recover very older infants. Because nerves recover very slowly, it may take several months, or even slowly, it may take several months, or even years, for nerves repaired at the neck to reach years, for nerves repaired at the neck to reach the muscles of the lower arm and hand. Many the muscles of the lower arm and hand. Many children with brachial plexus injuries will children with brachial plexus injuries will continue to have some weakness in the continue to have some weakness in the shoulder, arm, or hand. There may be surgical shoulder, arm, or hand. There may be surgical procedures that can be performed at a later procedures that can be performed at a later date that might improve functiondate that might improve function

Towel test Absence of biceps recovery by 3 months of age
is an indication of surgery The infants that did not pass the towel test At
6 months also did not pass it at 9 months are the potential candidates for surgery
Lefevre and Diament called it as hand to face test
In supine, the child face is covered with towel Shoulder flexion, elbow flexion and extension
and finger flexion and extension are needed for the test.
He/she passes the test if he/she then removes the towel from the face.

Surgical exploration should be done within 6 months of life

TRACTION
Many doctors use traction (pulling on baby's head) or fundal pressure (where the nurse climbs on the bed and jumps down onto your stomach) before anything else and these are not only the least effective techniques, but dangerous to mother and baby.

Suprapubic Pressure
Suprapubic pressure (where the doctor or nurse makes a fist and pushes hard on the baby's shoulder just above the pubic bone) can be applied.

Gaskin Manuever
The Gaskin Maneuver consists of having mom roll onto all fours (or assisting if necessary). During the process, many babies become dislodged and pop right out. If this doesn't happen, then the doctor actually has better access to help wiggle the baby around until the shoulder releases and the rest of baby is born (Woods or Rubin maneuver).

Manual Delivery of Post arm
Manual delivery of posterior arm: Insert hand into the vagina and flex the posterior arm of the fetus, bringing it across the chest. The posterior arm is then delivered over the perineum which allows the provider to rotate the fetus to allow delivery of the anterior shoulder once the rotation has disimpacted it from the pubic symphysis.
