Effects of motor tasks through photos and videos in patients after stroke

Efeitos da demonstração de tarefas motoras por fotos e vídeos em pacientes pós-acidente vascular encefálico

The aim of the present study was to examine the effects of motor tasks through photos and videos in post-stroke patients. Participants were 12 patients and 10 control people. Five functional tasks were presented in four different sequences and participants had to indicate the ones which reached the goal correctly. By ANOVA it was found that the response time of the patients was greater than of the control group (photos = patients: 4833 ± 310 ms, control: 1112 ± 76 ms, p = .0001 and videos = patients: 3655 ± 242 ms, control: 2451 ± 270 ms, p = .0001). Patients performed better with videos (p = .001). These results may influence therapeutic strategies and enable a discussion about a possible impairment of the mirror neuron system.
