************************************************** *******

>re.: GAIT ANALYSIS SYSTEMS, recommendations for reliable and
simple >system.
>
>
>To all who have PRACTICAL EXPERIENCE with different gait
>analysis systems:
>For investigations in orthopaedic patients we need a
>gait analysis system with a sampling frequency of 50 Hz (video
>system) and a measuring accuracy of about 3 - 4 mm in a measuring
>field of 2 x 3 meter. Possibly a system with one camera on each side

>included into programs written in Visual Basic, as DLLs or Avtive
>Controls. Reliable routines for tracking hidden markers would be
>favourable.

>Recommendations for systems which are GOOD suited OR should better
>NOT be bought are highly welcome .
