The PROSPAX (PROgression chart of SPAstic ataXias) project, which focuses on ARSACS and SPG7 ataxias , is a collaborative effort between neurologists across several sites throughout Europe and Canada. The overall aim is to gain a better understanding of how spastic ataxias progress over time to prepare well-designed treatment trials for these conditions . This is called ‘trial-readiness’. The Foundation is the Patient Advocacy Organisation on that project. More details .
