Background: Health care providers, especially those with direct patient contact, are one of the occupational groups most injured by
WRMD. A combination of lifting heavy loads with awkward postures is most hazardous, especially for low back pain. Adjusting the
bed, during performance of manual tasks, creates a more erect thus safer for the therapist's lumbar spine.
Objectives: To compare adjusted bed height between two passive manual tasks and to find an optimal topographic location to rely
on when adjusting bed height.
Design: Cross-sectional study.
Methods: Eighty physical therapy students performed two specific passive movements: shoulder flexion (SF) and straight leg raise of
thigh (SLR), each task executed either on a standard bed and an adjustable one. The lumbar angle was measured at the beginning and
at the end of each task using a smartphone, which served as an inclinometer. The rate of perceived exertion (RPE) was measured after
each task. Distances from anatomical points on the hand and pelvis to the floor were measured.
Results: The mean bed height for SF was significantly higher than for the SLR. The third knuckle hand technique and the radial
styloid process of the wrist (RSP) were established as the most valuable anthropometric points to rely on when adjusting the bed
height. Both tasks had higher RPE rates and the subjects experienced more of a bent back bent when performing the tasks on a
standard bed height compared to an adjustable one.
Conclusions: Each manual task requires its own bed height adjustment. Moreover, it is essential that any manual task entailing lifting
appears to place the therapist at risk for lower back pain as a result of awkward postures. The third knuckle and RSP are recommended
as reference points when adjusting the bed height.
