F1 (classification)

F1, also T1 and SP1, is a wheelchair sport classification that corresponds to the neurological level C6. Historically, it was known as 1A Complete. People in this class have no sitting balance, and are tetraplegics. They may be able to perform limited actions with one hand. They lack sitting balance, and have limited head control and respiratory endurance. The process for classification into this class has a medical and functional classification process. This process is often sport specific.

This is wheelchair sport classification that corresponds to the neurological level C6. In the past, this class was known as 1A Complete.

In 2002, USA Track & Field defined this class as, "These athletes have no hand function, are unable to use the muscles that straighten their elbows, and their hands remain in contact or close to the pushing rim with the power coming from their elbow flexion. Neurological level: C6" Disabled Sports USA defined the functional definition of this class in 2003 as, "Have no grip with non-throwing arm. (Use 'resin' or adhesive-like substance for grip.)"

Sports recommended for people in this class include swimming, billiards, shooting and bowls.

Disabled Sports USA defined the neurological definition of this class in 2003 as C6. The classification neurologically can include tetraplegics with spinal lesions level C5/C6. The location of lesions on different vertebrae tend to be associated with disability levels and functionality issues. C5 is associated with elbow flexors. C6 is associated with wrist flexors.

Disabled Sports USA defined the anatomical definition of this class in 2003 as, "Have functional elbow flexors and wrist dorsi-flexors. May have elbow extensors (up to power 3) but usually do not have wrist palmar flexors. May have shoulder weakness. Have no sitting balance." People with C4 lesions have head control, and limited respiratory endurance. People with C5 lesions have abduction of the arms, and flexion of the arm. People with C6 lesions have abduction and flexion of the arms, and wrist extension.

The location of lesions on different vertebrae tend to be associated with disability levels and functionality issues. People with C4 lesions can control electronic devices using a mouth controlled joystick. People with a lesion at C5 or C6 have an impairment that effects the use of their hands and lower arm. People with C5 can perform some actions with one of their arms, and can propel a wheelchair with modified rims that make it easier to do. People with C6 can have a weak grasp with their wrist. They can roll over in bed. They have some independence in that they can eat and groom themselves without assistance. They may also be able to transfer themselves to a wheelchair. In terms of motor functions, people in this class who are C4-C6 tetraplegics may have issues with their biceps, deltoids, rhomboids and rotor cuffs. They may have an absence of sensation in their hands, wrists and forearms. People in this class have a total respiratory capacity of 81% compared to people without a disability. The functional characteristics for this class at the 1990 Stoke Mandeville Games had this class scoring a 0 - 3 for triceps on the MRC scale, with severe weakness of the trunk and lower limbs.
