Acupoint GB34 has been used to treat patients with stroke
to help motor function recovery and is accompanied with the increased neuronal
activities in motor-related brain regions according to a neuroimaging study published
in journal of Brain Research.
Acupoint GB34 is one of the most common acupoints used in
treating motor-related conditions in China for a very long time. However its
underlying mechanism is not clear. Recently scientists in China explored the
central mechanism of immediate effect of acupuncture stimulation at GB34 on the
motor-related network of stroke patients with hemiplegic.
Functional magnetic resonance image (fMRI) was used to
assess the changes in neuronal activities of different brain regions before and
after acupuncture stimulation at GB34 and compare the changes between GB34 and
sham acupoint. Function MRI data analysis showed that acupuncture at GB34 may
increase motor-cognition connectivity, including visual-memory, motor task
learning, and motor intention, meanwhile decrease compensation of unaffected motor
cortex and ipsilateral synkinesis, which can definitely promote the
rehabilitation of hemiplegia and spasm.
This study demonstrated the underlying mechanism of GB34
central action in post-stroke patient with hemiplegia.
