A8 (classification)

A8 is an amputee sport classification used by the International Sports Organization for the Disabled (ISOD).for people with acquired or congenital amputations. People in this class have one arm amputated below the elbow, but through or above the wrist joint. Their amputations impact their sport performance, including being more prone to overuse injuries. Sports people in this class are eligible to participate in include athletics, swimming, cycling, amputee basketball, amputee football, lawn bowls, and sitzball.

Definition
Type of amputation for an A8 classified sportsperson.

This class is for people who have one arm amputated below the elbow, but through or above the wrist joint.[1] This classification is sometimes abbreviated as B/E.[2] In competing in some sports, this class may have a different name:

Class Abbr Athletics Cycling Skiing Swimming Comparable classifications in other sports Ref
A8 B/E T46, F46 LC1 LW 6/8.2 S8, S9 Amputee basketball: Open.

Amputee football: Goalkeeper.

Badminton: STU5.

Lawn bowls: LB3.

Sitzball: Open.

Ten-pin bowling: TPB10.

Performance

The nature of a person's amputations in this class can effect their physiology and sports performance. Because they are missing a limb, amputees are more prone to overuse injuries in their remaining limbs. Common problems for intact upper limbs for people in this class include rotator cuffs tearing, shoulder impingement, epicondylitis and peripheral nerve entrapment.[9]

Governance

This classification was set up by ISOD, with the current version adopted in 1992 and then modified in 1993.[1][10] IWAS was created following the merger of ISOD and International Stoke Mandeville Games Federation (ISMGF) in 2005. Subsequently, IWAS became the classification governing body for some amputee sports.[2][11]

Sports

Athletics

For athletics competitions that use the IPC athletics classification system, this class competes in T46, F46 and T47.[1][4][12] The extent of their below elbow amputation needs to be greater than a below wrist amputation or they are not eligible to compete in this class.[13] The missing arm weight changes their running form by creating differences in rotation between hip and shoulder.[12]

A study of was done comparing the performance of athletics competitors at the 1984 Summer Paralympics. It found there was no significant difference in performance in times between women in A6, A7 and A8 in the discus, women in A6, A7 and A8 in the shot put, women in the A6, A7 and A8 in the long jump, women in A6, A7 and A8 in the 100 meter race, women in A5, A6, A7 and A8 in the 100 meter race, men in the A3, A4, A5, A6, A7, A8 and A9 in the discus, men in A6, A7 and A8 in the discus, men in A1, A2, A3, A4, A5, A6, A7, A8 and A9 in the javelin, men in A6, A7 and A8 in the javelin, men in A8 and A9 in the shot put, men in A6, A7 and A8 in the high jump, men in A6, A7 and A8 in the long jump, men in A6, A7 and A8 in the 100 meter race, men in A7 and A8 in the 400 meter race, and men in A7 and A8 in the 1,500 meter race.[14]

In general, track athletes with amputations in this class should be considerate of the surface they are running on, and avoid asphalt and cinder tracks.[1]

Basketball

There is a basketball variant called amputee basketball. It uses the ISOD classification system as to whom is eligible to participate, but it is open in terms of all eligible classes, including this one, can play. There is no point system for who is allowed on the floor at any given time like there is in wheelchair basketball.[15]

Cycling
See also: Para-cycling classification and LC1 (classification)

People in this class tend to be classified in cycling events as LC1. The class is for cyclists with upper limb disabilities including amputations.[5] Classification is handled by Union Cycliste Internationale.[16]

Football

One of the sports available to people in this class is amputee football. There are two variants of the game, one with 4 players a side and one with 7 players a side. In both variants, A2 and A4 players must be field players while A6 and A8 players must be goalkeepers. In the 4 person variant, there are two halves of 15 minutes each. In the 7 person variant, there are two halves of 25 minutes each.[5]

Swimming
Main articles: Para-swimming classification, S8 (classification), and S9 (classification)

People with amputations are eligible to compete in swimming at the Paralympic Games.[17][18] A8 swimmers may be found in several classes. These include S8, and S9.[3] People with below the wrist amputations may be eligible to compete in swimming.[13] Prior to the 1990s, this class was often grouped with other amputee classes in swimming competitions, including the Paralympic Games.[14]

S8 and S9 swimmers in this class have similar start times to people with legs amputations in S8 to S10 classes.[19] Paralympic S9 swimmers in this class can get water entry distance off the block comparable to Olympic athletes. S8 swimmers in this class have much shorter points of entry into the water off the block.[19] Compared to able bodied swimmers, swimmers in this class have a shorter stroke length and increased stroke rate.[19] Because their legs are their greatest strength, they modify their entry into the water to take advantage of this.[19]

Other sports

There are a number of sports to people in this class, including lawn bowls. A8 lawn bowlers can be classified as LB3.[20] They can also play badminton, where they are classified as STU5. The class is for standing players with minimal arm impairment.[20] Another sport open to people in this class is sitzball, the precursor to sitting volleyball. It is open to A1 to A9 classified players along with anyone who might be classified as "les autres" or who have lesser amputations that would not qualify them for ISOD classification. It is not open to people with spinal cord injuries. Play is open, with no requirements as to which types of disabilities are on the court at any time.[20] Ten pin bowling is also open to people in this class, where they compete in the TPB10 class.[21] Rowing is another sport open to people with amputations. In 1991, the first internationally accepted adaptive rowing classification system was established and put into use. People from this class were initially classified as A2 for people with double amputations.[22]

Becoming classified

Classification is often based on the anatomical nature of the amputation.[2][23] The classification system takes several things into account when putting people into this class. These includes which limbs are effected, how many limbs are effected, and how much of a limb is missing.[10][24]

For this class, classification generally has four phase. The first stage of classification is a health examination. For amputees, this is often done on site at a sports training facility or competition. The second stage is observation in practice, the third stage is observation in competition and the last stage is assigning the sportsperson to a relevant class.[13] Sometimes the health examination may not be done on site because the nature of the amputation could cause not physically visible alterations to the body.[25]

Classification can be sport specific. For athletics, the training portion of the observation may include being asked to demonstrate their skills in athletics, such as running, jumping or throwing.[26]
