ABSTRACT

Briefly the project is to design an effective and low cost arm trainer that can be used by a stroke survivor at home. Recent research suggests that stroke survivors can recover significant use of their arms by performing repetitive motor function exercises over a period of time. These days, devices for stroke patient are expensive and commonly can be found at the hospitals and rehabilitation centres. It may be difficult to a patient to go to the rehabilitation centre or a hospital and also it will cost more. To overcome this problem, the project has been developed and the objectives are stated above. The result of the design should not be too complex and detail. The result has shown that the design is simple and not too complicated because it was designed as simple as possible. As for the movement of the arm trainer, it will not be forcing to users because some of the parameters have been studied. As conclusion, this design can be used as an idea to generate more effective and low cost arm trainer in the future.
