Cerebral ischaemia - Inability to undertake any physical activity greater than 3 METs Factor
RMA definition
A "MET" is a unit of measurement of the level of physical exertion. 1 MET = 3.5 ml of oxygen/kg of body weight per minute or, 1.0 kcal/kg of body weight per hour, or resting metabolic rate.
General information
A MET approximates to the energy required to rest quietly in bed. A 70 kg man would use about 3 METs when walking at 4 km per hour.
Note:
- The factor requirements are a severe test of a limited capacity for exertion. The MET ratings for common activities provides guidance for assessing whether or not certain activities meet the RMA SOP factor.
- The SOP factor requires "an inability to undertake any physical activity greater than 3 METs …". Therefore, there must be a physical or mental incapacity that prevents the person engaging in such activity. The incapacity must be due a physical inability with a generalised, rather than localised, effect on the level of physical activity able to be undertaken. For example the person with adhesive capsulitis may not be able to work as a mechanic or play golf, but can readily engage in other activities where the level of energy expended is greater than 3 METs. Similarly, the person with osteoarthrosis of the knees can undertake upper arm activities and/or swimming at levels easily exceeding 3 METs.
- Lifestyle choices, lack of opportunity, or lack of facilities do not constitute an inability to undertake any physical activity greater than 3 METs.

Preliminary questions [12570]
12942 there is some evidence that an inability to undertake any physical activity greater than 3 METs may be a factor in the development of the condition under consideration, a cerebrovascular accident.
33535 the veteran has been unable to undertake any physical activity greater than 3 METs for at least 5 years at some time.
33536 the veteran was unable to undertake any physical activity greater than 3 METs for at least 5 years as a result of an illness or injury which is identifiable.
12606 the veteran has established the causal connection between the inability to undertake any physical activity greater than 3 METs and VEA service for the clinical onset of cerebrovascular accident.
12608 the veteran has established the causal connection between the inability to undertake any physical activity greater than 3 METs and eligible service for the clinical onset of cerebrovascular accident.
or
12607 the veteran has established the causal connection between the inability to undertake any physical activity greater than 3 METs and operational service for the clinical onset of cerebrovascular accident.
Clinical onset and operational service [12607]
25620 the identified illness or injury made a material contribution to the veteran's inability to undertake any physical activity greater than 3 METs for at least the five years before the clinical onset of the condition under consideration, a cerebrovascular accident.
33538 the identified illness or injury which prevented the veteran from undertaking any physical activity greater than 3 METs is causally related to operational service.
Clinical onset and eligible service [12608]
7979 the identified illness or injury made a material contribution to the veteran's inability to undertake any physical activity greater than 3 METs for at least seven years.
25621 the identified illness or injury made a material contribution to the veteran's inability to undertake any physical activity greater than 3 METs for at least the seven years before the clinical onset of the condition under consideration, a cerebrovascular accident.
33537 the identified illness or injury which prevented the veteran from undertaking any physical activity greater than 3 METs is causally related to eligible service.
