H3 is a para-cycling classification. The UCI recommends this be coded as MH3 or WH3.
Definition
Union Cycliste Internationale (UCI) defines H3 as:
H3.1 (ex-H2.1)
Paraplegic with impairments corresponding to a complete lesion from Th1 to Th3
Very limited trunk stability
Impaired sympathetic nerve system
Non-spinal cord injury, but functional ability profile equivalent to sport class H3.1 (ex-H2.1)
Recumbent position in handbike mandatory (AP-bikes).
H3.2 (ex-H2.2)
Paraplegic with impairments corresponding to a complete lesion from Th4 to Th10
Limited trunk stability
Non-spinal cord injury, functional ability profile equivalent to sport class H3.2 (ex-H2.2)
Recumbent position in handbike mandatory (AP-bikes)
Moderate quadriplegia with/without athetosis/ataxia
Severe hemiplegia (non-ambulant)
Severe diplegia (non-ambulant) and athetosis/ataxia
Neurological impairments with at least grade 1 spasticity in upper limb.
The cycle
This classification can use an AP2 recumbent, which is a competition cycle that is reclined at 30 degrees and has a rigid frame. This classification can also use an AP3 hand cycle which is inclined at 0 degrees and is reclined on a rigid competition frame. The classification can also use an ATP2 cycle which is a long seated forward cycle on a rigid frame.
