At least they are using objective measurement changes to see what therapy works. Every stroke researcher should be following this.

Abstract
This article reviews the concepts underlying functional neuroimaging
and its use to study brain function change as a result of recovery and
neurorehabilitation for speech, voice, and swallowing. The role of
neurovascular coupling for quantifying brain function change in response
to behavioral demands is explained. The types of changes in brain
function that are measured and how they should be interpreted are
addressed for the study of brain function abnormalities in developmental
and acquired speech, voice, and swallowing disorders. One challenge is
to separate changes in brain function due to recovery from those that
are secondary to the development of compensatory skills during therapy.
The advantages of functional magnetic resonance imaging and functional
near-infrared spectroscopy are compared. The use of transcranial
magnetic stimulation for the study of brain function is reviewed. In
addition, more recent methods for the modulation of brain function using
transcranial magnetic and electrical stimulation over the cortex are
examined. These technologies can be used by clinical investigators to
gain better understanding of normal brain function and for learning how
abnormalities in brain function might be addressed. Both are likely to
lead to new therapeutic approaches to neurorehabilitation of speech,
voice, and swallowing disorders.
