Objectives:
To determine the effect of caregiver experience on the loads generated at the low back of caregivers during lift use.
Methods:
Twenty-one caregivers were asked to perform five activities designed to simulate the activity of moving a patient from a bed to a wheelchair and back to the bed. Each caregiver was instrumented with ForceShoes as well as a set of reflective markers used to determine body posture. The caregiver was asked to perform each task alone as well as with the help of a second non-instrumented caregiver. Caregivers were asked to repeat the five activities in a total of three different conditions with each lift: 1) Solo - the instrumented caregiver works alone
2) Primary – the instrumented caregiver who takes control of the lift device while working in a pair
3) Secondary - the instrumented caregiver who supports the patient while working in a pair
Results:
When the 21 caregivers were divided into two groups based on their amount of lifting experience, we found inexperienced caregivers (n=11, mean experience = 2.6±1.6 years) generated significantly higher loads than experienced caregivers (n=10, mean experience = 15.4±10.2 years).
Conclusions:
Experienced caregivers generate lower loads on their bodies compared to inexperienced caregivers when operating both floor or overhead lifts with one or two caregivers.
