R4. Efficacy Studies Project: "Assessing the Efficacy of Products Transferred Through the T2RERC"


Vathsala Stone

The T2RERC has successfully transferred a range of products to market in order to benefit persons with disabilities. This study proposes to conduct laboratory and home trials to assess the quality and value of these transferred products in terms of how they affect the consumer's functional capabilities. The efficacy trials will gather comparative evidences to answer the question, "How well do the products commercialized through the T2RERC actually benefit end users?" In the laboratory trials the product will be compared to its most equivalent commercial product in the market at the time of transfer; whereas the home trials will consider any or all alternative methods used by the consumer as the product's critical competitors. The study involves three broad phases, the last two phases covering the laboratory and home trials, and the first phase dedicated to developing the instruments and operational protocols for the trials. We expect that the Phase One indicators, instruments and evaluation protocols will, cumulatively over the project period, result in a resource guide useful for product evaluators.
