“…The articles used various methods for assessing outcomes, such as instrumentation methods: back pain monitor (BPM; Holmstrom & Ahlborg, 2005), Ohio State University LMM (Hess et al, 2004;Mirka et al, 2003,); observational methods as Task Recording and Analysis on Computer System (Luijsterburg et al, 2005;Van der Molen et al, 2004), videotaping and 3D strategic strength prediction program (SDSSPP; Vink et al, 2002), NIOSH Lifting Equation (Mirka et al, 2003), University of Michigan 3DSSPP (Mirka et al, 2003); and questionnaire methods (Holmstrom & Ahlborg, 2005;Ludewig & Borstad, 2003;Vink et al, 2002). All these methods provided information linking to intermediate measurements of musculoskeletal health, such as frequency and duration of flexion, bending, velocity and acceleration, compression force, muscle strength, and endurance.…”
