### Osteoarthritis - Lifting loads while bearing weight Factor

Bearing weight in this context means supporting a weight through a joint.  This contention only applies to osteoarthritis of a lower limb joint. Lifting while standing, weight loads the ankles, knees and hips, but bench pressing weights does not.

The RMA defines a joint of the lower limb to mean "the hip, knee, ankle, sacro-iliac joint or any joint of the foot".

In operational service cases the SoP requirements are lifting loads of at least 25 kg while bearing weight through the affected joint to a cumulative total of at least 120,000 kg within any 10 year period.

In eligible service cases the SoP requirements are lifting loads of at least 35 kg while bearing weight on the affected joint to a cumulative total of at least 168,000 kg within any 10 year period.

##### Calculations

To accumulate 120,000 kg at the rate of 25 kg per lift or 168,000 kg at the rate of 35 kg per lift would require the following number of lifts per day over various periods of time:

 Years Lifts per day 1 2 3 4 5 6 7 8 9 10 13.15 6.58 4.38 3.28 2.63 2.19 1.87 1.64 1.46 1.3

You can calculate the number of lifts required to accumulate the required total weight by dividing 120,000 (or 168,000) by the weight being lifted.  For example, if a person regularly lifted 27 kg as a storeman, then he would need to lift this weight 4,444 times to accumulate 120,000 kg.  Dividing this number by the number of days in the period during which he did the lifting will give you the number of lifts per day required during this period, in order to accumulate the necessary total weight.  Thus if the person only worked as a storeman for six months regularly lifting 27 kg, and did no other heavy lifting, he would need to have lifted 27 kg 24.4 times each day (4,444 divided by 180), in order to meet the SOP requirements.

Where the person performed a number of activities for varying lengths of time, lifting various weights, it will be more practical to simply add the weights lifted.  For example if the above person also worked in a vehicle workshop for two months and lifted 30 kg twice every day, then you would:

• multiply 27 kg by 4 times per day by 180 days in six months, to obtain the total for his stint as a storeman, then
• multiply 30 kg by 2 times per day by 60 days in two months, to obtain the total for his time in the workshop.

The sum of these two figures will give the cumulative total.
