The relative efficacy of Neuro-Developmental Treatment (N.D.T.) versus the Brunnstrom method was studied from the perspective of the functional recovery of stroke patients. An alternating treatment design (B-C-B-C) was used. Each intervention phase lasted 5 weeks. The functional recovery of the patients was assessed every week by using the Barthel Index and the Action Research Arm test, by registering walking velocity, and by performing gait analysis. At the start and at the end of each intervention phase, neurological and neuropsychological assessments took place. Time series analysis indicated that for one patient only, walking speed progressed more during the Brunnstrom phases than the N.D.T. phases. This result did not generalize towards other parameters or patients studied. For upper extremity function and maximum walking speed, a high correlation was found between the week post stroke in which the patient showed the first signs of recovery and the end condition after 20 weeks.

The transfer effects of scanning training of right-brain-damaged stroke patients with visual inattention have been studied. Five patients were treated according to a B-C-B-D design. The first B phase lasted for 2, 4, or 6 weeks, whereas the other intervention phases had a fixed duration of 2 weeks. During all phases physical therapy was given. Additionally, occupational therapy was applied during the B phases, training on a scanning apparatus during the C phase, and training on reading tasks during the D phase. At least three times in each intervention phase, performance was measured using a computerized visual scanning test, a line bisection test, and a letter cancellation test. In addition, wheelchair navigation was assessed. For four out of the five patients a significant positive effect of visual scanning training on visual scanning behaviour was found. This effect, however, appeared to be restricted to the task which was specifically trained. Over the group as a whole no evidence could be found for any transfer of visual scanning training effects to the domain of gross motor skills.
