2 Commencement
This instrument commences on 28 November 2023.

6 Definitions
The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument.
7 Kind of injury, disease or death to which this Statement of Principles relates
(1) This Statement of Principles is about chronic exertional compartment syndrome of the lower leg and death from chronic exertional compartment syndrome of the lower leg.
Meaning of chronic exertional compartment syndrome of the lower leg
(2) For the purposes of this Statement of Principles, chronic exertional compartment syndrome of the lower leg:
(a) means raised muscle compartment pressure manifesting with exercise-induced pain and tightness originating in the calf or shin which typically resolves or reduces with rest; and
(a) excludes:
(i) fracture, including stress fracture;
(ii) lower leg tendinopathies or bursitis;
(iii) nerve entrapments (sural or superfoneal);
(iv) popliteal artery entrapment syndrome;
(v) acute sprain and acute strain; and
(vi) vascular insufficiency.
Death from chronic exertional compartment syndrome of the lower leg
(3) For the purposes of this Statement of Principles, chronic exertional compartment syndrome of the lower leg, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's chronic exertional compartment syndrome of the lower leg.
Note: terminal event is defined in the Schedule 1 – Dictionary.
8 Basis for determining the factors
The Repatriation Medical Authority is of the view that there is sound medical-scientific evidence that indicates that chronic exertional compartment syndrome of the lower leg and death from chronic exertional compartment syndrome of the lower leg can be related to relevant service rendered by veterans, members of Peacekeeping Forces, or members of the Forces under the VEA, or members under the MRCA.
Note: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary.
9 Factors that must exist
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting chronic exertional compartment syndrome of the lower leg or death from chronic exertional compartment syndrome of the lower leg with the circumstances of a person's relevant service:
(1) running or jogging an average of at least 30 kilometres per week for the 4 weeks before the clinical onset or clinical worsening of chronic exertional compartment syndrome of the lower leg;
(2) undertaking weight bearing exercise involving repeated activity of the lower leg on the affected side for:
(a) a minimum intensity of 5 METS; and
(b) for at least 4 hours per week; and
for at least the 4 weeks before the clinical onset or clinical worsening of chronic exertional compartment syndrome of the lower leg;
Note 1: Examples of weight bearing exercise involving repeated activity of the lower leg at a minimum intensity of 5 METS include marching, sustained brisk walking, playing football, and dancing.
Note 2: MET is defined in the Schedule 1 - Dictionary.
(3) increasing the frequency, duration or intensity of weight bearing activity involving the lower leg on the affected side:
(a) by at least 100 percent; and
(b) to a minimum intensity of 5 METs; and
(c) for at least 2 hours per day;
within the one week before the clinical onset or clinical worsening of chronic exertional compartment syndrome of the lower leg;
Note: MET is defined in the Schedule 1 - Dictionary.
(4) inability to obtain appropriate clinical management for chronic exertional compartment syndrome of the lower leg before the clinical worsening of chronic exertional compartment syndrome of the lower leg.
10 Relationship to service
(1) The existence in a person of any factor referred to in section 9, must be related to the relevant service rendered by the person.
(2) The clinical worsening aspects of factors set out in section 9 apply only to material contribution to, or aggravation of, chronic exertional compartment syndrome of the lower leg where the person's chronic exertional compartment syndrome of the lower leg was suffered or contracted before or during (but did not arise out of) the person's relevant service.
11 Factors referring to an injury or disease covered by another Statement of Principles
In this Statement of Principles:
(1) if a factor referred to in section 9 applies in relation to a person; and
(2) that factor refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(2) of the VEA;
then the factors in that Statement of Principles apply in accordance with the terms of that Statement of Principles as in force from time to time.
