(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. 

*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.” 

ii. Time and Duration of Treatment 

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.
