UCI CYCLING REGULATIONS  − Bilateral impaired handgrip with a muscle grade of less than or equal to 3 in one  hand and less than 3 in the other hand;  − Non-spinal cord injury/incomplete spinal cord injury with a sport specific activity  limitation equivalent to sport class H2;  − Asymmetric or symmetric bilateral involvement with at least grade 2 spasticity  in upper limb and lower limbs, trunk control impacted by hypertonia  − Hypertonia on activity making it impossible to ride a bicycle or tricycle.  − Severe athetosis/ dystonia (E.g. large amplitude of excessive motion and long  durations of excessive motions) in the lower limbs and trunk, with upper limbs  less affected, making it impossible to ride a bicycle or tricycle;  − A comparable mixture of ataxia/athetosis/dystonia and hypertonia/spasticity  with a sport specific activity limitation equivalent to sport class H2, making it  impossible to ride a bicycle or tricycle. − Paraplegic with impairments corresponding to a motor complete lesion from Th1  to Th10;  − Trunk stability varies from very limited trunk stability (Nil to minimal muscle  strength in abdominals) to limited trunk stability (reduced to normal upper and  lower abdominal strength) with a muscle grade of 0-4; − Non-spinal cord injury/incomplete spinal cord injury with a sport specific activity  limitation equivalent to sport class H3.  − Asymmetric or symmetric bilateral involvement with at least grade 2 spasticity  in lower limb/s and at least spasticity grade 1 in upper limb. Hypertonia on  activity affecting trunk or legs and making it impossible to ride a bicycle or  tricycle;  − Severe athetosis/dystonia (E.g. large amplitude of excessive motion and long  durations of excessive motions) in the lower limbs and trunk, making it  impossible to ride a bicycle or tricycle;  − A comparable mixture of ataxia/athetosis/dystonia and hypertonia/spasticity  with a sport specific activity limitation equivalent to sport class H3, making it  impossible to ride a bicycle or tricycle.
