DIGITAL TELEMETRIC ELECTROGONIOMETRY FOR GAIT ANALYSIS

Llerena Fernández, JE. ; Ortega Oviedo, O ; Téllez Rivera, MA. and Harta Olivares, R.R.

We developed a digital system for gait analysis based on electrogoniometric techniques, which uses digital RF for the data transfer and a DSP for processing and displaying them.

The system has three main parts : a portable transmitter, a receiver and an interface to the operator ( operating system).

The transmitter digitises 8 time-multiplexed channels using an 8-bit resolution ADC (at 1 OOHz), each one is a filtered electrogoniometric signal. (The electrogoniometers are attached to 4 joints in each of the lower limbs: hip, knee, anlde and the phalanx­metatarsian.) After digitisation, the data are added correction and parity bits and coded for PWM, to be sent to the receiver.

The receiver has two components, the receiver circuitry itself andan interface to a personal computer. The receiver circuit is an external tuned amplifier which conditions the data to be read by a PC add-on card, based on a floating-point DSP TMS320C30, whose task is to compute all of the biomechanical parameters and send them to the PC internal RAM, to be displaied.

Among this parameters are joint angles as well as cycle time, step times, stride time, single­and double-limb support time and, swing and stance ratios. This computations are real time plotted on a computer screen based on the user' s selection. Such plots migth be automatically analysed for detecting pathological cases and gait abnormalities, by means of genetic algorithms or evolutive systems.

The main advantage this work has over other similar systems is the freedom of movement the patient has, due to the fact of being unplugged from any static system. Furthermore, the cost of the sensing technique is lesser than that of IR-digitising based systems. Additionaly, goniometry gives an excelent analog signal, ideal for digitisation and further post-processing.

The power disipation ofthe transmitter is only 12mW, with a single battery lasting 30 hours of continuous use, and it is pocket-sized (5 x 7 x 2cm ) (H x L x W.) It weights l lüg including batteries and has a working range of 20m.
