Gait analysis has become an important method to measure the pressure that a subject makes
in each step, allowing the detection of several anomalies, which generate many pathology and
problems in the subject.
The aim of this project is to design and develop an insole, which must be able to measure the
pressure that a subject generates along his/her gait path.
On the theoretical side, an investigation about the most adequate positions to place the
pressure sensors was carried out in order to detect the pressure during the gait and compare
it between feet movements. It was also required to understand the foot anatomical distribution,
mainly as bones are concerned.
On the other side, the practical one, a circuit was designed to do these measurements. Data
recorded had been sent to a computer through Bluetooth connection. Then an algorithm for
automated movement detection was developed, as well as an interface to make these
measurements easier. Using a Bluetooth connection and a batterie it was possible to develop
a wireless device, keeping the influence on the subject’s gait behaviour at a minimum by
providing the most comfort possible. The device was fixed at the gastrocnemius muscle height
trying not to affect the subject’s gait. For this purpose, a case was also developed to locate the
prototype.
Finally, the results were analysed in order to know if the pressure registered had consistent
values, and if the pressure detected in each point followed the logical order as it has been
seen in other studies (Vidya K. Nandikolla, 2017). It was also tried to observe any relationship
or change between the pressure in different foot points and a slope floor increasement. [--]
