The purpose of this paper is to chronicle the development of a new feedback type of rehabilitation technology by a team of therapists and engineers and the process of testing and refining to optimize the system for clinical use. The new rehabilitation system is personal computer (PC) based and uses signals from a patient, detected by surface electromyography (sEMG), to control cursor movements within the PC. Therapists select from a variety of engaging activities designed to encourage different muscle activations and movements. The choice of computer and Technology to Induce Movement led to the system being called TIM. This paper concludes with a case description of changes in ankle motor function after use of the TIM system was added to the treatment program of a patient with chronic hemiplegia, whose progress toward improved ankle muscle performance had reached a plateau.
