Remote therapy, involved in a tele-rehabilitation program, should monitor daily 
motion activity. Furthermore, patients should have all possible means to improve 
rehabilitation care at their disposal, such as suitable prostheses and 
biofeedback tools. During stroke rehabilitation at home, the most used equipment 
is the AFO prosthesis, which is also called codivilla-spring, as it is used in 
cases of both bilateral and mono-lateral damage. A new codivilla-spring 
prosthesis with sensors for telemonitoring / telerehabilitation has been 
designed and constructed. It provides step counting. It is based on a couple of 
force sensing resistors affixed in the plantar area of the prosthesis, and a 
wearable unit with a micro-processor microP PIC 16F877 (Microchip, USA). The 
data exchange is assured by the Aurel-XTR-434H telemetric system. While 
ambulating, FSRs detect the pressure of the foot-tip and heel. The PIC on the 
basis of an algorithm furnishes the step-counting. The proposed 
sensorized-codivilla-spring (SECOSP) was tested as a step-counter on three 
subjects after stroke-rehabilitation with mono-lateral damage at Level 2 of the 
Tinetti test of unbalance. These subjects performed 100 steps with two different 
instructions (fast, slow). The mean error was lower than 0.6 %. The next phase 
will be the optimization of SECOSP for long term medical application in a 
patient's home.
