Design and construction of a prototype system for gait analysis for research in subjects with balance problems

This work presents the design and construction of a prototype of a distributed system for gait analysis with the aim in helping diagnosis and rehabilitation treatment of elderly population with balance disorders. A suitable set of requirements for the recording and subsequent analysis of the human gait parameters were defined. The prototype should be able to record the movements of the body where it is placed, transmit the acquired data and work with complete autonomy during the time it takes to make records. The prototype was built on a PCB of reduced weight and dimensions. It was tested and compared with a commercial device and the results were satisfactory.
