T47 (classification)

T47 is a disability sport classification for disability athletics primarily for competitors with a below elbow or wrist amputation. T47 is a classification for track events but unlike the other T40 to T46 classifications it has no equivalent F47 classification for field events. The amputee sports equivalent class is ISOD the A8 class. People in this class can have injuries as a result of over use of their remaining upper limb.

This classification is for disability athletics. This classification is one of several classifications for athletes with ambulant related disabilities. Similar classifications are T40, T42, T43, T44, T45 and T46. As of 2016, the International Paralympic Committee defines this classification as being for athletes with a unilateral upper limb impairment resulting in some loss of function at the shoulder, elbow and wrist and which impacts sprints primarily. The impact of the impairment is comparable to the activity limitations experienced by an athlete with a unilateral through wrist/below elbow amputation. This class includes people from the ISOD A8 class.

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.

A study was undertaken comparing the performance of athletics competitors at the 1984 Summer Paralympics when the ISOD classification system was in use. 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.
