The personal lift-assist device and lifting technique: a principal component analysis

EM Sadler, RB Graham, JM Stevenson - Ergonomics, 2011 - Taylor & Francis
The personal lift-assist device (PLAD) is a non-motorised, on-body device that acts as an
external force generator using the concept of stored elastic energy. In this study, the effect of …

Local dynamic stability of trunk movements during the repetitive lifting of loads

RB Graham, EM Sadler, JM Stevenson - Human movement science, 2012 - Elsevier
The local dynamic stability of trunk movements was assessed during repetitive lifting using
nonlinear Lyapunov analyses. The goal was to assess how varying the load-in-hands affects …

Liver transplantation for NASH-related hepatocellular carcinoma versus non-NASH etiologies of hepatocellular carcinoma

EM Sadler, N Mehta, M Bhat, A Ghanekar… - …, 2018 - journals.lww.com
Background Liver transplant (LT) for nonalcoholic steatohepatitis (NASH) related

Local dynamic stability of the lifting kinematic chain

RB Graham, PA Costigan, EM Sadler, JM Stevenson - Gait & Posture, 2011 - Elsevier
While a stable trunk and centre of mass (CoM) trajectory are required during lifting, it is
unclear how stability is controlled. Thirty healthy participants (15M, 15F) performed …

Does the personal lift-assist device affect the local dynamic stability of the spine during lifting?

RB Graham, EM Sadler, JM Stevenson - Journal of biomechanics, 2011 - Elsevier
The personal lift-assist device (PLAD) is an on-body ergonomic aid that reduces low back
physical demands through the restorative moment of an external spring element, which …

Gender difference and lifting technique under light load conditions: a principal component analysis

EM Sadler, RB Graham… - Theoretical Issues in …, 2013 - Taylor & Francis
The majority of lifting research uses male subjects, and thus it is necessary to investigate if
gender differences exist in lifting technique that may limit extrapolation of these studies …

Addressing caregiver mental health in the neonatal ICU
