The role of visual feedback in conventional therapy and future research

Application of virtual reality in stroke rehabilitation indicates a beneficial effect on motor learning. We performed a literature search into the application of feedback in experimental therapeutic sessions. We gained more insight into the application of different feedback modalities in current therapy in an observational study. We also studied the effectiveness of different feedback modalities in research settings in a literature search. In current clinical practice mainly verbal feedback is provided, while in research combined use of auditory and visual, or sensory and visual feedback is provided.
