T46 and F46 are disability sport classification for disability athletics. People in this class have a single below or above the elbow amputation. The amputee sports equivalent class is ISOD the A6 and A8 classes. People in this class can have injuries as a result of over use of their remaining upper limb. The classification process to be included in this class has four parts: a medical exam, observation during training, observation during competition and then being classified into this class.
This classification is for disability athletics. T46 is for track events and F46 is for field events. This classification is one of several classifications for athletes with ambulant related disabilities. Similar classifications are T40, T42, T43, T44, T45 and T47. Jane Buckley, writing for the Sporting Wheelies, describes the athletes in this classification as: "Single above elbow/Single below elbow amputation or similar disability." The Australian Paralympic Committee defines this classification as being for athletes who have the "Single arm, above or below elbow amputation. Normal function in both lower limbs. Other impairments in trunk. Upper limb function in throwing." After the introduction of the T47 classification in 2013, the International Paralympic Committee redefined T46 as being for athletes who: "...have a unilateral upper limb impairment that affects the shoulder and/or elbow joint of one arm and which is comparable to the activity limitations in running and jumps roughly comparable to that found in an athlete with a unilateral above elbow amputation. Athletes who have impairments of both arms, affecting elbow and wrist and roughly comparable to the activity limitations experienced by an athlete with bilateral through wrist / below elbow amputations of both arms, or an athlete with one above elbow amputation and one below elbow amputation, will also be placed in this class". The International Paralympic Committee defined this classification on their website in July 2016 as, "Upper limb/s affected by limb deficiency, impaired muscle power or impaired range of movement".
