Physical Demands of LPN vs Care aide

Hi all,

I am an occupational therapist working with a young nursing student studying to be an LPN. She was in a serious MVA and sustained injuries that left her with neck and back pain. She has worked as a care aide and had difficulty with her symptoms due to the obviously very physical nature of the job. I am trying to determine if work as an LPN is actually less physically demanding or at par with care aide work. I would imagine that it would depend on the setting, however I would greatly appreciate some information from working professionals on exactly the range of job duties and phyiscal demands associated with LPN work.

Thanks So much!
