I wonder if this is being taught in therapist classes? Who is going to translate this into an actual therapy protocol that do-it-yourself patients can follow?

Although strokes typically affect only one side of the body,
rehabilitation appears to work best when both sides of the body are
engaged. A study done by Ken Takitama of the University of Tokyo and
Masato Okada of the RIKEN Brain Science Institute in Wako, Japan, found
that the two-sided approach was especially important in getting
functioning back in a weakened arm and hand. Recovery of movement in the upper limb usually lags behind that of the leg and foot.
The authors wrote that their study "suggests that bimanual movement
facilitates the reorganization of a damaged motor cortex because this
movement induces rotations in the preferred directions (PDs) of motor
cortex neurons . . . Although previous computational studies
investigated the unimanual movements of stroke patients, individuals
often move their arms bimanually. Bimanual movement is effective for the
recovery of paretic [partially paralyzed] arm movement . . . Rotations of the encoding PDs facilitate cortical reorganization."
Also important to note, several other studies have shown that, as
with any motor skill, practice makes perfect when it comes to stroke
rehabilitation. Patients who diligently repeat therapeutic movements
tend to recover more movement than those who are not as hard-working.
