The use of an advanced reciprocating gait orthosis by paraplegic individuals: a follow-up study.

This article describes the results of a follow-up study of 14 paraplegic individuals who were fitted with the ARGO (Advanced Reciprocating Gait Orthosis--STEEPER) at least 1 year previously. It was found that 85% were still using the apparatus on a regular basis. The general satisfaction of the users was high, although the functional use was limited. Therapeutic reasons appeared to be the main reason for wearing the ARGO. The points that were most appreciated were the psychological and physiological benefits of standing and walking. Discussion with the users who were paraplegic provided valuable information concerning possible technical improvements to the ARGO.

Electrical impedance tomography systems based on voltage drive.

At the ESAT-MICAS research facility in Leuven, several EIT systems have been designed and realised. The latest hardware set-up makes use of a PC to control the data collection and to reconstruct the images. A voltage drive strategy and no common-mode feedback are some of its specific characteristics. The function-generator produces signals with a frequency between 10 and 100 kHz, so multifrequency images can also be produced. Static images have already been obtained and (semi-)real time imaging is possible with our latest mark IV system. This system has 16 bit analogue-to-digital convertors and is capable of taking 50 x 10(3) samples/s.
