Development and validation of a C5/C6 motion segment modelGibson, Thomas J., Graduate School of Biomedical Engineering, Faculty of Engineering, UNSW January 2006 (has links)
There is a large body of work investigating whiplash-associated injury in motor vehicles and its causation. Being unable to detect the actual injury and having to use the symptoms of the sufferer as a surrogate has made progress in understanding the injury causation slow. Still lacking are the causal relationships between the biomechanical load on the vehicle occupant in the crash, the resulting loading on the neck and the actual injuries suffered. The optimisation of the design of vehicle safety systems to minimise whiplash needs a better understanding of human tolerance to these injuries. This thesis describes the development of a mathematical multi-body C5/C6 motion segment model to investigate the causation of soft-tissue neck injury. This model was validated with available static in-vitro experimental data on excised motion-segments and then integrated into the existing, validated multi-body human head and neck model developed by van der Horst, to allow the application of realistic dynamic loads. The responses and injury sensing capability of the C5/C6 model were compared with available data for volunteers and cadavers in rear impacts. The head and neck model was applied to the investigation of a group of real rear impact crashes (n = 78) of vehicles equipped with a crash-pulse recorder and with known postcrash injury outcomes. The motion of the occupants in these crashes had previously been reconstructed with a MADYMO BioRID II dummy-in-seat model validated by sled testing. The occupant T1 accelerations from these reconstructions were used to drive the head and neck model. The soft-tissue loading at C5/C6 of the head and neck model was analysed during the early stage of the impact, prior to contact with the head restraint. The loading and the pain outcome from the vehicle occupants in the actual crash were compared statistically. For the longer-term whiplash-associated pain outcomes (of greater than 1 month duration) for these occupants, the C5/C6 model indicated good correlation with the magnitude of the shear loading on the facet capsule. In lower severity impacts, the model result supported a second hypothesis of injury to this motion segment: facet surface impingement.

The effects of whiplash-associated disorders on the kinematic and the electromyographic responses of individuals submitted to anterior surface translations in the sitting position /Patenaude, Isabelle. January 2007 (has links)
The goal of this Master's project was to characterize the postural control patterns of individuals with chronic whiplash-associated disorders and to compare these patterns with those of healthy individuals. The postural reactions in response to low-intensity translations of the sitting position were assessed by way of kinematic and electromyographic analyses. We found that whiplash individuals display an earlier onset of their head displacement and a pattern of trunk displacement characterized by greater flexion at the upper levels of the spine, compared to the lower levels. Moreover, whiplash individuals present a tendency for a late recruitment of their neck flexors and for a greater use of a pattern of neck extensor muscle inhibition. These results suggest that individuals with whiplash-associated disorders may compensate their altered neck functional ability by modifying their relative movements along the spine and by adopting altered motor strategies to compensate for their painful muscles.

A placebo controlled trial to determine the efficacy of chiropractic manipulation in the treatment of whiplash injuryKruger, Brian January 2000 (has links)
Dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Chiropractic, Technikon Natal, 2000. / The purpose of this study was to investigate the efficacy of manipulation of the cervical spine in the treatment of subacute and chronic whiplash injury utilizing a placebo treatment as a means of comparison. Treatment of whiplash injury still requires research in order to establish the effectiveness of manipulation as an adjunct in the management of this type of injury (Spitzer et al. 1995, Foreman and Croft 1995:468). Manipulation and mobilization have demonstrated some degree of effectiveness in the treatment of whiplash injury in past studies (Woodward et al. 1996, McKinney 1989 / M
