In DOLLY 3, the third Dortmund Lumbar Load Study, the load on the lumbar spine through manual patient handling was investigated. The current publication (part 5) contains concrete recommendations in the form of task-specific practical action instructions. These are based on pair-wise comparisons of task executions combined with varied spinal loadings, in order to identify the essential differences of posture and force development of the caregiver with respect to a back-friendly handling of patients. In summary, the newly developed scientifically substantiated actions instructions provide an effective basis to limit the biomechanical overload risk for the spine of healthcare workers.
The Dortmund Lumbar Load Studies – DOLLY
The akronym ”DOLLY” originates from the english title ”The Dortmund Lumbar Load Study”. The DOLLYs represent comprehensive investigations regarding the occupationally induced load on the lumbar spine in diverse vocational fields. The initial DOLLY demonstrates a monitoring of lumbar load for complete working shifts, DOLLY 2 provides a lumbar-load register for a variety of typical manual materials handling tasks. DOLLY 3 focuses on care activities. This 5-part study was conducted by the Leibniz Research Centre for Working Environment and Human Factors (IfADo) in intensive cooperation with the German Social Accident Insurance Institution for the Health and Welfare Services (BGW):
- Part 1: Developing the (laboratory) methodology and exemplary applications
- Part 2: Deriving relevant criteria for occupational-disease evaluations
- Part 3: Load reduction via ”small aids” and ”optimized working mode”
- Part 4: Load modulation while handling obese persons
- Part 5: Action instructions for back-friendly patient handling
