I am looking to compare two groups - mobility activity after surgery.

Group 1 - is a 'low ability' (ie, very old, frail)

Group 2 - is 'high ability' (able to move around before surgery).

The numbers in each group are NOT means, they are simply counts of patients. Ie, on the first day, 37 of Group 1 got up and moved around, and 25 of Group 2.

I have numbers for 5 days. Not continuous (ie, they are not the same patients each day - just counts of patients moving in each group).

I would like to compare the 2 groups over the 5 days to see if there is a significant difference between each group.

ANOVA - is for comparing means - which is not applicable here? (I think).

Initially I was thinking chi square, but now I am wondering if a t-test would be best?

thank you for your comments!
