This
project analyzes the human gait cycle by way
of specially designed potentiometer (displacement)
sensors placed at the ankle, knee, and hip
to measure the angular displacements of these
anatomical landmarks. The angular displacements
are then calibrated in terms of voltage. The
voltages are acquired by the ZiLOG microcontroller
and sent through the serial port. The signal
is then processed using computer software,
and graphs are plotted indicating the angular
displacement with respect to the percentage
of the gait cycle. Attached to a PC, this
system can be used as a portable low-cost
method for obtaining the temporal parameters
of the gait. Rather than being intended as
a replacement for the more complicated systems
used in hospitals, this design offers support
by acquiring preliminary data, therefore reducing
the time of hospitalization.
