PR2 (previously TA) is a Paralympic rowing classification for people with trunk and arm function.
[1][2] Rowing Australia defines this classification as "This class is for rowers who have trunk movement and who are unable to use the sliding seat to propel the boat because of significant weakness in the lower limbs.
It will include many people such as: Bilateral above knee amputation, or significantly impaired quadriceps, or People with a neurological impairment equivalent to a complete lesion at L3 level, or an incomplete lesion at L1, or A combination of the above such as one leg with around knee amputation and one leg with significant quadriceps impairment; or Classification by the international sports federation for rowers with cerebral palsy (CPISRA) as eligible to be in CP Class 5.
[6] People with lesions at L4 have issues with their lower back muscles, hip flexors and their quadriceps.
[7] People with lesions at the L4 to S2 who are complete paraplegics may have motor function issues in their gluts and hamstrings.
[10] Currently, people with complete spinal cord injury at L3 level or incomplete lesion at L1 compete in TA.
[15] Australians seeking classification through Rowing Australia need to provide several documents to a classifier at the time of application, including a doctor's statement that documents their impairment, when it was acquired and if the doctor expects changes in the level of disability in terms of increases or decreases in the severity of the disability.
