STANDARDS SECTION XVIII - TOURNAMENT STANDARDS OF PERFORMANCE (a) All treatable musculoskeletal injuries that manifest and are  assessed as part of a kinetic chain continuum; and (b)  Any and all clinical manifestations of heat illness and cramping  subject to the following: (i) A player may receive treatment for muscle cramping  only during the time allotted for change of ends and/ or set breaks. Players may not receive a MTO for muscle  cramping. In cases where there is doubt about whether  it is (x) an acute medical condition, (y) non-acute medical  condition, inclusive of muscle cramping, or (z) non-treatable  medical condition, the decision of the PHCP in conjunction  with the Tournament Physician, if appropriate, is final. If a  player exhibits symptoms of an illness or heat illness (i.e.,  heat stroke or heat exhaustion) and cramping is one of the  manifested symptoms, a MTO may be taken, which will be  determined by the PHCP at the time of evaluation. (ii)  A player who has stopped play by claiming an acute medical  condition, but is determined by the PHCP, in conjunction  with the Tournament Physician, if appropriate, to have  muscle cramping, shall be ordered by the Supervisor/ Referee or Chair Umpire to resume play immediately. If  the player cannot continue playing due to severe muscle  cramping, the player may forfeit the point or game(s)  needed to get to a change of ends or set break in order  to receive treatment.* There may be a total of two (2)  change of ends treatments for muscle cramping in a match,  not necessarily consecutive. If it is determined by the  Chair Umpire or Supervisor/Referee that gamesmanship  was involved, then a Code Violation for Unsportsmanlike  Conduct may be issued. ii.  Time and Duration of Treatment *The chair umpire will announce to the players and spectators: “Miss/ Mrs. ____ is requesting immediate medical treatment for cramping.  She may receive this treatment only on a changeover/set break  and therefore is conceding all points and games up to the next  changeover/set break.” Should the MTO take place, it will not exceed three (3) minutes. It  shall begin after the completion and diagnosis of medical condition  by the PHCP and Tournament Physician, if required, and be timed  from the moment when the PHCP is ready to commence treatment. 358
