FCE's are usually done in relation to your job title. I worked as a cashier, so when I had my FCE it involved...walking, to observe my gait...squatting, balance, repetitive lifting of different weights, pushing, pulling different weights, etc.
It is important to tell the observer when you feel fatigue or pain during these activities.
I had a more 'in depth' evaluation done at one point that also 'tested' my fine motor skills since at one time I worked as an assembler and they wanted to determine if I could return to work in that capacity. Part of the test was reading and following directions...listening to oral directions and carrying them out...putting small pegs in holes by hand, then with pliers, etc.
Seashell may have more to add from the Physical Therapist perspective.
Ultimately, I was given 'restrictions' as to how much weight I could lift...5lbs maximum with right upper extremity...10 lbs maximum with both upper extremities...frequent breaks...etc. My employer was very good about following the 'prescription' from the FCE.
Best wishes to you.
