My Deep Brain Stimulators Poem by Andy Caldwell

We test my DBSs
implanted in my brain 
I turn off the right machine
suddenly the left of me is free
I can move it painlessly
and my heart ceased to ache
my leg feels jitter free
On lingers my left machine
my right leg tight and tender
 My left hand free from bondage
for the shortest time.........
Soon the pain returns in force
muscles of my face contort
muscles of my limbs contract
as I wither on I ask 'Turn it back on'
though it sounds like gibberish 
Parkinson's is there in force
without my DBS machines
I go from bad to worse
and everything hurts
the test proves out
the machines work
