An Outcome Measure which Quantifies Hand Impairment

The GRASSP is a clinical impairment measure for the upper limb for use after tetraplegia. The measure includes three domains which are important in describing hand function.

Psychometric Properties

Highly Responsive (Sensitive) to Change Over Time

Natural Recovery

Assess the Extent of Spontaneous (Natural) Recovery

Clinical Trials

Use in clinical trials to evaluate the effect of novel interventions

GRASSP Summary Scores

Measure the various aspects of complex sensori-motor upper limb function
