The defensive duo have been making regular trips to the
Blackberry Clinic in Milton Keynes, which proudly boasts it's "the
last resort".
Ferdinand has only just returned to the United team after
spending three months on the sidelines with a mystery back
injury.
Vidic has been struggling with a calf problem and has not played
for the club since December 30.
The pair have been travelling to Milton Keynes together by train
for weeks.
United turned to the Buckinghamshire clinic for help after club
physios struggled to find a solution to Ferdinand's long- standing
back problem.
The Blackberry Centre, which has been established for more than
20 years, specialises in the treatment of back, neck and joint
pains.
Clinic director Simon Petrides is a musculoskeletal physician
and has been overseeing their star clients' progress.
He said: "My greatest satisfaction is treating patients who
perceive us as the last resort, then wish they had come much
sooner.
"The sooner you seek treatment, the more beneficial the
outcome."
United have placed their faith in a centre that is convinced its
forward-thinking methods work and claims to have some of the best
skeletal and muscular physicians in the world working for it.
Petrides uses a variety of methods including manipulations,
injections and epidurals.
He also refers patients to the clinic's team for a
rehabilitation procedure that includes pilates sessions to aid
recovery.
It appears to be working. Ferdinand, who has been plagued by
back trouble all season, finally returned to the United team for
the 4-0 victory over Hull on January 23.
Vidic has been having problems with his calf for some time.
He pulled out of United's FA Cup third round tie against Leeds
in the warm-up.
That led to a fiery exchange between the central defender and
manager Sir Alex Ferguson over the seriousness of the injury.
Vidic, however, is still struggling to shake off the problem and is
continuing to have treatment at the Blackberry Centre.
Despite being named on the bench for United's clash with
Manchester City in the Carling Cup, he did not make it for the 3-1
victory at Arsenal last weekend.
Vidic is one of a number of players sweating on their futures at
Old Trafford and the club have yet to open talks on a new
contract.
His current deal ends in summer 2012 and it is now approaching
decision time for Ferguson.
Vidic's relationship with the manager has been put to the test
this season and the United chief is considering moving the big
Serbian on in the summer.
