The health of her joints in her knee i believe
it really depends on the persons condition
a walker if they just need a little support and have a hard time standing
a wheelchair if they cant walk
a walking stick and and transfer belt if they can walk and stand but need a little bit of support

It would depend on the type used.
PED's would boost performance by increasing heart rate and thus increasing the amount of oxygen rich blood.
However, depressants would have the exact opposite effect as they slow down your body.
Either way, both can negatively effect physical performance in the long term.
