Thesis
Sa'ed Al Qaroot, B. The effects of body fat percentage on inter-vertebral spinal mobility control from hyperextension spinal orthoses. (Thesis). University of Salford

Hyperextension spinal orthoses are common modalities in treating vertebral
fractures. Their objective is to retain the spine in a hyperextended position to
offload the fractured vertebra(e) and allow healing. To date, accurate insight into
the eff... Read More about The effects of body fat percentage on inter-vertebral spinal mobility control from hyperextension spinal orthoses.

Lateral whip, which is defined as sideward motion of the prosthetic heel away from the
line of progression during swing phase of gait, is one of the common gait deviations that
trans-femoral amputees exhibit during walking. It poses several negativ... Read More about An investigation into the relationship between knee axis alignment and swing phase whip during trans-femoral amputee gait.

components, which when assembled comprise the
trans-tibial prosthesis.

Does transverse plane mechanical compliance affect amputee gait and in-socket forces? (2006)
Journal Article
Twiste, M., Nester, C., & Kenney, L. (2006). Does transverse plane mechanical compliance affect amputee gait and in-socket forces?. Journal of Biomechanics, 39(S1), 171

Transverse plane rotation in an amputee's residual-limb appears to be less
than in non-amputees [1,2]. However, it remains unclear firstly, to what extent
this is driven by the properties of the prosthesis, and secondly, whether this
has detriment... Read More about Does transverse plane mechanical compliance affect amputee gait and in-socket forces?.

The effect of transverse rotation and longitudinal translation between prosthetic components during the gait of unilateral trans-tibial amputees (2004)
Thesis
Twiste, M. The effect of transverse rotation and longitudinal translation between prosthetic components during the gait of unilateral trans-tibial amputees. (Thesis). University of Salford

During stance phase of amputee gait, considerable forces are transmitted across the residual limb socket interface. These loads and associated gait patterns can be altered by introducing compliant elements into the prosthesis. However, previous studi...
