Clinical trials for common health conditions are constantly being designed and implemented in our institution, often with some urgency to meet funding deadlines. The scope and complexity of these trials has resulted in the need for databased computer management systems typically tailored to each project. Even with current advanced software resources, development, testing and implementation can take months for each new project. This presentation describes a new approach to this problem involving an adaptive table-driven software system using project-specific recruitment and screening data which we have developed using visual basic. The chief design criterion was that the software be reconfigurable by the user based on data tables that contain the parameters of the project design. Essentially, each new project would be implemented by generating new input to the tables, but without the need for reprogramming. The first system implemented was a branching phone screen application that presents questions in an interview format and records participant responses in a data table which can be judged against inclusion/exclusion criteria contained in another table as well as for status reports.Purpose
Methods
Some studies report greater repositioning error in LBP patients compared to healthy subjects with other studies showing no differences. This conflicting evidence may be due to different methodologies. A new tool, the Flexchair¯Back Balance Trainer measures consistency of lumbo-pelvic movement during visual tracking tasks which challenge the lumbo-pelvic region. This study aimed to establish the within day (WD) and between day (BD) reliability of a lumbo-pelvic tracking task using the Flexchair in healthy subjects, 22 subjects gave informed consent (10 females, 12 males (age 38.40(±9.29) Height 171.35cms (±8.07) weight 76.21kg (±18.55) Subjects completed six different tracking tasks on the Flexchair, 3 times in the first day with 2 hour of intervals between each test and once on a second and third visit with 2 days in between. Tests 1-6 are of increasing difficulty.Background
