In the RaceRunning Classification, athletes with severe athetoid, spastic, ataxic dystonic, or mixed quadriplegia are in this class.
The RR1 will have severe involvement in the lower extremities and trunk and moderate to critical participation in the upper extremities.
Only gross patterns of movement, flexion, and extension, with ineffective leg propulsion, are observed.
RaceRunning Classification System is independent and has no direct relationship with the CP classes.
Athletes with spasticity would have grade 3 and /0r 4 in lower extremities- grade 3 in the upper extremities on the ASAS.
Severe difficulty isolating individual joint movements in the lower extremities.
There is poor control of the stride.
Foot drag, severe asymmetry, or no alternate leg movements may be seen.
Upper extremities have poor control, and strapping may be necessary for hand placement.
A startle reflex may limit the start.
Severe difficulties in coordination of functional running movement, severely limited hand function, and poor trunk stability characterize this class.
