By Arianne Medrano, Psychology- Biology Emphasis, ‘19 Author’s Note: I wrote this literature review for my UWP 104F class in my fourth year at UC Davis. My goal is to become a physical therapist and one of the most common complaints I hear from older generations is that they cannot perform activities they once loved because of a ‘bad back.’ My father experienced a disc related injury, which led to sciatica, after he fell off a ladder. This prevents him from enjoying activities such as heavy-lifting, riding roller coasters or picking up his grandson. For these reasons, I was interested in researching effective prevention and treatments to help alleviate discomfort and improve quality of life.
