load and if loops

I created a prompt that loads an array with 50 values

I need to assign x to the values of that array to run an if loop. This is what I have so far. How can I improve my code to make it work?

pick_year = input('Pick a year: either 1997 or 2013: ')
for pick_year = 1997
   x = load('UPDRSscores_1997')
   if x == 0
        display('normal')
    elseif x == 1 
        display('slight')
    elseif x == 2
        display('mild')
    elseif x == 3
        display('moderate')
    elseif x == 4
        display('severe')
   end
end
