Leading national thinking on politics, government & public policy through Open Access research

Strathprints makes available scholarly Open Access content by researchers in the School of Government & Public Policy, based within the Faculty of Humanities & Social Sciences.

Research here is 1st in Scotland for research intensity and spans a wide range of domains. The Department of Politics demonstrates expertise in understanding parties, elections and public opinion, with additional emphases on political economy, institutions and international relations. This international angle is reflected in the European Policies Research Centre (EPRC) which conducts comparative research on public policy. Meanwhile, the Centre for Energy Policy provides independent expertise on energy, working across multidisciplinary groups to shape policy for a low carbon economy.

    There is widespread agreement that motion analysis is currently the gold standard for measuring human movement in a non-invasive manner [1]. Current commercially available systems, such as Vicon Plug in Gait (PiG, Vicon Motion Systems, Oxford, UK) have been developed over a number of years and are capable of providing a biomechanical analysis which is robust enough to dictate complex treatment plans, such as multi-level surgery [1]. However, due to the vast capabilities of PiG, it is a time consuming and technically complex protocol to deliver. Additionally, there are currently limited options for delivering motion capture using other protocols which vastly limits the use of motion analysis in other aspects of clinical care, such as outpatient rehabilitation. Cluster based marker sets may provide a faster and less technically complex alternative to models such as PiG; however these are currently not commercially available and have thus far been restricted to research environments. Therefore, the aim of this study was to develop a bespoke cluster based motion analysis protocol (Strathclyde Cluster Model; SCM) capable of calculating lower limb kinematics which could be implemented in routine clinical care in order to expand the use of motion analysis beyond research and complex clinical cases. Further aims included an assessment of the kinematic output and reliability of SCM in comparison to PiG. SCM is a motion analysis protocol which has been developed for routine clinical use, such as outpatient rehabilitation and therefore application of markers and participant calibration is quicker and easier than current commercial alternatives. Further, kinematic output and reliability are comparable between SCM and the current clinical gold standard. Therefore, SCM is a suitable alternative for providing an objective assessment of function and outcome in routine clinical practice.
