The aim of the study was a continuation of previously provided research on the tablets usability in the rehabilitation of old patients with cognitive disabilities after a brain stroke. First, the analysis of the pilot research results was provided. It gave a hope for possible rationalization of the rehabilitation process after proper improvement of the proposed mobile solution. Prototype examples of mobile rehabilitation applications were extended and integrated in the RehaMob - a single mobile solution. The mobile application includes six different types of tasks, which can be useful for stimulation and rehabilitation of language functions, short-term memory, etc. The RehaMob was made available again to the therapists in the rehabilitation center. Finally, the mobile application is used with good results in the therapy of patients with cognitive disabilities. The mobile solution is useful support for traditional rehabilitation process, but its influence to the rehabilitation progress is difficult to assess, because the RehaMob can be used only as additional tool.
