  7. Abstract:
  8. The recent project can be considered as a subset of Telerehabilitation, in the field of Telerehabilitation can be defined as the need for long-term data recording in order to determine each individual's movement pattern and compare it to the individual's best model or best practice. With this perspective, it can be said that the recent project, in more detail, remotely targets the use of foot plantar pressure to determine locomotor parameters. With this description, the FSR or force sensitive resistor sensor was selected for a number of reasons, including low cost, low weight and low thickness, and the data acquisition circuit was used to convert the sensors' analog signal to digital output, given the creep and hysteresis in these sensors. Data filtering method and applying significant threshold. 15 healthy subjects were involved in this project and passed the steps of ascending and descending, sitting and lifting from the chair. The results obtained by applying the fuzzy network and defining the corresponding fuzzy variables were able to obtain the type of motion in the first place and in the motion type in the second step and to explain the differences between these motions and useful parameters. Similar projects in the industry are expected to be used in the future
