<s>[INST] doctor,my daughter is 6 years old and has left arm erb palsy. we did PT for 6 years and hand movement improved to move above head.But lifting weight and rotation is very low as compared to right arm.Difference in arm strightness is noticed. what is the best range of activities will help to improve the left arm [/INST] Definately...as u know verbs palsy in left arm has lead to the weakness.....mainly this weakness will improve only by physiotherapy...... and yes the improvement is slow but steady....give the child tab vitamin b12 daily...along with physiotherapy which involves mainly shoulder and upper arm... prevent contractures and joint dislocation by making movement in every direction of all shoulder elbow and wrist.as the child to resist against your exercises movement....it will take the couple of years more... :) </s>
