Resumen:
Rehabilitation engineering and medicine have become integral and significant parts
of health care services, particularly and unfortunately in the last three or four decades, because
of wars, terrorism and large number of car accidents. Amputees show a high rate of rejection to
wear prosthetic devices, often because of lack of an adequate period of adaptation. A robotic
arm may appear as a good preliminary stage. To test the hypothesis, myoelectric signals from
two upper limb amputees and from four normal volunteers were fed, via adequate electronic
conditioning and using MATLAB, to an industrial robotic arm. Proportional strength control
was used for two degrees of freedom (x-y plane) by means of eight signal features of control
(four traditional statistics plus energy, integral of the absolute value, Willisons amplitude,
waveform length and envelope) for comparison purposes, and selecting the best of them as
final reference. Patients easily accepted the system and learned in short time how to operate it.
Results were encouraging so that valuable training, before prosthesis is implanted, appears as
good feedback; besides, these patients can be hired as specialized operators in semiautomatized
industry.
