Retention of motor changes in chronic stroke survivors who were administered mental practice

We need more research like this except they don't say whether this is for acute or chronic. Come on Stephen Page I expect better from you.
So does this contradict this one here?

Abstract: Study examined the retention of motor changes 3 months after participation in a regimen consisting of mental practice (MP) emphasizing paretic upper extremity use combined with repetitive task-specific (RTP) practice (MT+RTP). Participants were 21 individuals who had been randomly assigned to receive a 10-week regimen consisting of MP+RTP during valued activities and, as a group, had been shown to benefit from the intervention when compared with a matched control group. Directly after each of these sessions, subjects were administered audiotaped MP. These subjects’ paretic upper extremity (UE) motor levels were assessed before, after, and 3 months after intervention. Outcome measures included the UE section of the Fugl-Meyer Assessment of Sensorimotor Impairment, the Action Research Arm Test, the Arm Motor Ability Test, and the Box and Block Test. Results showed that none of the scores significantly changed from the period directly after intervention to the 3-month posttesting period. It is concluded that changes in paretic UE movement realized through MP+RTP participation are retained 3 months after the intervention has ended.
