The UKA rules does have a section on assistance, hard to be sure what'd apply here though:

RULE 144 ASSISTANCE TO ATHLETES Medical Examination and Assistance (1) (a) Medical examination / treatment and/or physiotherapy may be provided either on the competition area itself by the official medical staff appointed by the Organising Committee and identified by armbands, vests or similar distinctive apparel or in designated medical treatment areas outside the competition area by accredited team medical personnel specifically approved by the Medical or Technical Delegate for the purpose. In neither case shall the intervention delay the conduct of the competition or an athlete’s trial in the designated order. Such attendance or assistance by any other person, whether immediately before competition, once athletes have left the Call Room or during competition, is assistance. (b) An athlete shall retire at once from an event if ordered to do so by the Medical Delegate, or a medical doctor who is a member of the official medical staff, identified by armbands, vests or similar distinctive apparel. Note: The competition area, which normally also has a physical barrier, is defined for this purpose as the area where the competition is being staged and which has an access restricted to the competing athletes and personnel authorised in accordance with the relevant Rules and Regulations. (2) Any athlete giving or receiving assistance from within the competition area during an event shall be warned by the Referee and advised that, if there is any repetition, he will be disqualified from that event. If an athlete is subsequently disqualified from the event, any performance accomplished up to that time in the same round of that event shall not be considered valid. However, performances accomplished in a previous round of that event shall be considered valid. Note: In cases under Rule 144.3(a), disqualification may be made without warning. (3) For the purpose of this Rule, the following examples shall be considered assistance, and are therefore not allowed: (a) Pacing in races by persons not participating in the same race, by athletes lapped or about to be lapped or by any kind of technical device (other than those permitted under Rule 144.4(d)). (b) Possession or use of video recorders, radios, CD, radio transmitters, mobile phone or similar devices in the competition area. (c) Except for shoes complying with Rule 143, the use of any technology or appliance that provides the user with an advantage which he would not have obtained using the equipment specified in, or permitted by, the Rules. (d) The use of any mechanical aid, unless the athlete can establish on the balance of probabilities that the use of an aid would not provide him with an overall competitive advantage over an athlete not using such aid. (e) Provision of advice or other support by any official of the competition not related to or required by his specific role in the competition at the time (e.g., coaching advice, indication of the take- off point in a jumping event except to indicate a failure in horizontal jumps, time or distance gaps in a race etc.). (4) For the purpose of this Rule, the following shall not be considered assistance, and are therefore allowed: (a) Communication between the athletes and their coaches not placed in the competition area. In order to facilitate this communication and not to disturb the staging of the competition, a place in the stands, close to the immediate site of each Field Event, should be reserved to the athletes’ coaches. (b) Medical examination / treatment and/or physiotherapy necessary to enable an athlete to participate or continue participation once on the competition area under Rule 144.1. (c) Any kind of personal safeguard (e.g. bandage, tape, belt, support, etc.) for protection and/or medical purposes. The Referee, in conjunction with the Medical Delegate, shall have the authority to verify any case should he judge that to be desirable. (See also Rules 187.4 and 187.5.) (d) Heart rate or speed distance monitors or stride sensors or similar devices carried or worn personally by athletes during an event, provided that such device cannot be used to communicate with any other person. (e) Viewing by athletes competing in Field Events, of images of previous trial(s), recorded on their behalf by persons not placed in the competition area (see 144.1 Note). The viewing device or images taken from it must not be taken into the competition area.
