context_page_description: S2, SB1, SM2 are disability swimming classifications used for categorizing swimmers based on their level of disability. People in this class have limited use of their arms, and no or extremely limited use of their hands, legs and trunk. Swimmers in this class have a variety of different disabilities including cerebral palsy and amputations.
  Swimmers in this class have a number of events they can participate in including the 50m and 100m Freestyle, 200m Freestyle, 50m Backstroke, 50m Butterfly, 50m Breaststroke and 150m Individual Medley events.
context_section_description: This is  wheelchair sport classification that corresponds to the  neurological level C7. In the past, this class was known as 1B Complete, 1A Incomplete. The location of lesions on different vertebrae tend to be associated with disability levels and functionality issues. C7 is associated with elbow flexors. C8 is associated with finger flexors. Disabled Sports USA defined the anatomical definition of this class in 2003 as, ""Have functional elbow flexors and extensors, wrist dorsi-flexors and palmar flexors. Have good shoulder muscle function. May have some finger flexion and extension but not functional." People with lesions at C7 have stabilization and extension of the elbow and some extension of the wrist. People with a lesion at C7 have an impairment that effects the use of their hands and lower arm. They can use a wheelchair using their own power, and do everyday tasks like eating, dressing, and normal physical maintenance. People in this class have a total respiratory capacity of 79% compared to people without a disability.
  Swimming classification is done based on a total points system, with a variety of functional and medical tests being used as part of a formula to assign a class. Part of this test involves the Adapted Medical Research Council (MRC) scale.  For upper trunk extension, C8 complete are given 0 points.

  People with spinal cord injuries in S2 tend to be tetraplegics with complete lesions below C6, or tetraplegics with complete lesions below C7 who have additional paralysis in their plexus or in one arm. These S2 swimmers have no hand or wrist flexion so are unable to catch water.  Because of a lack of trunk control, they are unstable in the water and have hip drag.  As they have no leg mobility, their legs drag.  They normally swim the backstroke as they lack head control to breathe effectively for the freestyle.  They start in the water, sometimes with assistance for initial propulsion.
  For swimming with the most severe disabilities at the 1984 Summer Paralympics, floating devices and a swimming coach in the water swimming next to the Paralympic competitor were allowed. A study of was done comparing the performance of athletics competitors at the 1984 Summer Paralympics.  It found there was little significant difference in performance times between women in 1A (SP1, SP2), 1B (SP3), and 1C (SP3, SP4) in the 25m breaststroke. It found there was little significant difference in performance times between women in 1A (SP1, SP2), 1B (SP3), and 1C (SP3, SP4) in the 25m backstroke. It found there was little significant difference in performance times between women in 1A (SP1, SP2), 1B (SP3), and 1C (SP3, SP4) in the 25m freestyle. It found there was little significant difference in performance times between men in 1A (SP1, SP2), 1B (SP3), and 1C (SP3, SP4) in the 25m backstroke. It found there was little significant difference in performance times between men in 1A (SP1, SP2), 1B (SP3), and 1C (SP3, SP4) in the 25m freestyle.  It found there was little significant difference in performance times between men in 1A (SP1, SP2), and 1B (SP3) in the 25m breaststroke.
