ORIGIN OF GRASSP
GRASSP Version 1 (GV1) was developed in 2006 by the GRASSP Development and Research Group. It was designed using elements of the Link Hand Function Test, Quadriplegia Hand Assessment Tool and Sollerman Hand Function Test. GV1 has been tested for the psychometric properties during early development. The psychometric properties are excellent; evidence for the reliability, validity and responsiveness are published.
Development of the GRASSP has been a staged process with a number or different research groups and funding agencies involved. Once the GRASSP V1 had been assembled and GRDG conducted a cross sectional study to field test and establish the psychometric properties of reliability and validity.
CROSS SECTIONAL STUDY
This study was conducted in Europe, Canada and the USA. Seventy-two patients were enrolled into a study designed to evaluate the reliability and validity of the GRASSP. This study was conducted on a sample of chronic patients.

Longitudinal Study Group
This study was a longitudinal study enrolling 130 patients in Canada and Europe to establish responsiveness, recovery profiles and minimally clinical important difference (MCID). The responsiveness of the GRASSP is excellent and it is more sensitive than some of the existing measures in SCI. Data collection for the longitudinal study concluded in November of 2014. MCID has been established, but not yet published. This longitudinal dataset has also enable the team to perform Rasch Analysis, which has rendered a revision to GRASSP Version 1. The GRDG is currently in the process of launching GRASSP Version 2.
