Perception of Efforts in Working Postures

Abstract

45 seconds, w i t h r a t e d perceived e x e r t i o n (RPE) g i v e n a f t e r 15, 30 and 45 seconds. The whole t e s t s e r i e s was repeated twice. The r e s u l t s show t h a t i t i s p o s s i b l e t o e v a l u a t e d i f f e r e n t body postures by RPE a c h i e v i n g a t o t a l r e l i a b i l i t y a-value over 0.96.

Ergonomic assessment of the surgeon's physical workload during standard and robotic assisted laparoscopic procedures

“…The CR‐10 and NASA‐TLX scales that were used proved to be an effective reflection of the real physical workload . We were actually able to show that for senior surgeons during real operations, this new surgical approach considerably reduces the physical stress and strain felt.…”

“…During surgery, the physical difficulty perceived was evaluated using the Borg CR‐10 scale , the scale accepted for evaluating the physical workload imposed on surgeons . It is based on an estimate by the surgeon of the physical stress and strain felt, scored between 1 and 10 (1 indicating lack of strain and 10 being extremely uncomfortable and painful strain).…”

An evaluation of vibration and other effects on the accuracy of grip and push force recall

“…Some subjects tend to rate exertion or discomfort at the low end of the scale while others consistently deviate towards the high end. While each individual develops a personal assessment criteria, studies have shown that a subject's RPE is highly repeatable for many varied work postures (Wangenheim et al 1986). In the Wangenheim et al study (1986), 31…”
