Sensory stimulation therapy (SST) is an experimental therapy that aims to use neural plasticity mechanisms to aid in the recovery of somatosensory function after stroke or cognitive ageing. Stroke and cognitive ageing are well known sources of cognitive loss, the former by neuronal death , the latter by weakening of neural connections .
The treatment delivers electrical pulses to the brain during rehabilitation therapy [BBC] Two years ago Michael Koers was a fit and healthy 62-year-old - a courier who liked to keep busy at the ...
Unlike many effects of stroke, where the clinician is able to judge the particular area of the brain that a stroke has injured by certain signs or symptoms, the causation of apraxia is less clear. A common theory is that the part of the brain that contains information for previously learned skilled motor activities has been either lost or ...
[medical citation needed] It is now accepted that Dejerine–Roussy syndrome is a condition developed due to lesions interfering with the sensory process, which triggered the start of pharmaceutical and stimulation treatment research. The last 50 years have been filled with refractory treatment research. As of the early 2000s, longer treatments ...
One study looked into the effects of pallesthesia on stroke patients. [3] They theorized that sinusoidal stimulation may be an effective therapy; however, the results were inconclusive. It is rare for current research to use pallesthesia because better methods of testing the sensory system have been developed.
In order to affect brain (neuronal) activity, sensory stimulation must be within the frequency range of roughly 0.5 to 25 hertz (Hz) [citation needed]. Touch, photic and auditory stimulation are capable of affecting brain wave activity. A large area of skin must be stimulated to affect brainwaves, which leaves both auditory and photic ...
