RESEARCH UPDATE from WDDDY What Doctors Don’t Tell You Doctors do the worst thing possible with wounds and injuries -
06 October 2010
If you go to your doctor with a wound or a sports injury, he will do the very worst thing for you - he will try to reduce the inflammation. But don’t blame him, it’s the way generations of doctors have been taught at medical school, and only this week researchers have discovered the therapy is wrong.
Doctors have always been taught that it’s important to reduce the inflammation as quickly as possible – but researchers have now discovered that it’s nature’s way of healing damaged muscles.
Faced with an acute muscle injury caused by trauma – such as a sports injury – or by chemicals, infections or drugs, the doctor usually prescribes an NSAID drug in order to reduce the inflammation. Once the inflammation is under control, the wound will begin to heal, he says.
But what he’s been taught is the exact opposite of the way the body works. Inflammation is an important part of the healing process, as researchers from the Cleveland Clinic in Ohio have revealed this week.
Inflammatory cells around an acute muscle injury produce a high level of a growth factor that naturally increases the rate of muscle regeneration, they have discovered.

In the last decade, transcranial
magnetic stimulation (TMS) has been used increasingly as a tool to explore
themechanisms and consequences
of cortical plasticity in the intact human cortex.
Because the spatial accuracy of the techniqueis
limited, we refer to this as plasticity at a regional level. Currently,
TMS is used to explore regional reorganization in three different ways. First, it can map changes
in the pattern of connectivity within and between different cortical areas
or their spinal projections. Important examples of
this approach can be found in the work on motor cortex representations
following avariety of interventions
such as immobilization, skill acquisition, or stroke. Second, TMS can be used
to investigate the behavioural relevance of these changes. By applying
TMS in its "virtual lesion" mode, it is possible to interfere
with cortical function and ask whether plastic reorganization within a
distinct cortical area improves function. Third, TMS can
be used to promote changes in cortical function. This is achieved by using
repetitive TMS (rTMS) to induceshort-term
functional reorganization in the human cortex. The magnitude and
the direction of rTMS-induced plasticity depend on extrinsic factors (i.e.
the variables of stimulation such as intensity,frequency,
and total number of stimuli) and intrinsic factors (i.e. the functional
state of the cortex targeted by rTMS). Since conditioning effectsof rTMS are not limited to the stimulated
cortex but give rise to functional changes in interconnected cortical areas,
rTMS is a suitable toolto investigate
plasticity within a distributed functional network. Indeed, the lasting
effects of rTMS offer new possibilities to studydynamic
aspects of the pathophysiology of a variety of diseases and may have therapeutic
potential in some neuropsychiatric disorders.

input can remodel human cortical motor organization, yet the input characteristics
that promotereorganization
and their functional significance have not been explored. Here we show
with transcranial magneticstimulation
that sensory-driven reorganization of human motor cortex is highly dependent
upon the frequency, intensity, and duration of stimulus applied. Those
patterns of input associated with enhanced excitability (5 Hz, 75% maximal
tolerated intensity for 10 min) inducestronger
cortical activation to fMRI. When applied to acutely dysphagic stroke patients,
swallowing corticobulbar excitabilityis
increased mainly in the undamaged hemisphere, being strongly correlated
with an improvement in swallowing function.Thus,
input to the human adult brain can be programmed to promote beneficial
changes in neuroplasticity and function after cerebral
injury.[em can be done with thought and movement!]
