Fig. 5: Hand pose illustration and maximum isometric wrist moments vs. flexion angle.

From: Data-driven ergonomic risk assessment of complex hand-intensive manufacturing processes

Fig. 5

Hand flexion/extension (a) and the corresponding maximum isometric wrist flexor/extensor moments (b) during positive flexion force is shown. The curve comprises two segments: a linear relationship in the left section and a quadratic relationship in the right section, fitted using linear and second-degree polynomial models respectively.
