Achieving the required functionality of a trans-tibial prosthesis during the stance phase
of gait (e.g., shock absorption, close to normal roll-over characteristics, and smooth
transition into swing) depends on the “Amputee Independent Prosthesis P... Read More about Stance phase mechanical characterization of transtibial prostheses distal to the socket : a review.

The effects of transverse rotation angle on compression and effective lever arm of prosthetic feet during simulated stance (2012)
Journal Article
Major, M., Howard, D., Jones, R., & Twiste, M. (2012). The effects of transverse rotation angle on compression and effective lever arm of prosthetic feet during simulated stance. Prosthetics and Orthotics International, 36(2), 231-235. https://doi.org/10.1177/0309364611435996

Background and Aim: Unlike sagittal plane prosthesis alignment, few studies have observed the effects of transverse plane alignment on gait and prosthesis behaviour. Changes in transverse plane rotation angle will rotate the points of loading on the...

A model is presented for describing the Amputee Independent Prosthesis Properties (AIPP) of complete assemblies of trans-tibial prosthetic components distal to the socket. This new AIPP model includes features of both lumped parameter and roll-over m... Read More about Amputee independent prosthesis properties - a new model for description and measurement.

Investigating effects of mechanical properties of trans-tibial prostheses on user performance (2008)
Journal Article
Major, M., Twiste, M., Kenney, L., & Howard, D. (2008). Investigating effects of mechanical properties of trans-tibial prostheses on user performance. Journal of Biomechanics, 41(S1), 416-416. https://doi.org/10.1016/S0021-9290%2808%2970415-9

As the design of trans-tibial prostheses has
continued to advance, this has led to a wide range
of alternative commercially available modular
components, which when assembled comprise the
trans-tibial prosthesis.

Measurement system for the evaluation of alternating pressure redistribution mattresses using pressure relief index and tissue perfusion – a preliminary study (2008)
Journal Article
Twiste, M., & Rithalia, S. (2008). Measurement system for the evaluation of alternating pressure redistribution mattresses using pressure relief index and tissue perfusion – a preliminary study. Primary intention, 16(4), 192-198

Clinicians who are selecting dynamic support surfaces such as alternating pressure redistribution mattresses (APRMs) for the
prevention and treatment of pressure ulcers are faced with commercial literature that predominantly reports on magnitudes of...

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?.

A cam-displacement transducer device for measuring bi plane prosthetic motion (2004)
Journal Article

An electromechanical system is described that comprises a cam and two linear displacement transducers for measuring
two-degree of freedom. This is aimed at quantifying the extent and pattern of both transverse rotation and longitudinal translation... Read More about A cam-displacement transducer device for measuring bi plane prosthetic motion.

Transverse rotation and longitudinal translation during prosthetic gait - a literature review (2003)
Journal Article
Twiste, M., & Rithalia, S. (2003). Transverse rotation and longitudinal translation during prosthetic gait - a literature review. Journal of rehabilitation research and development, 40(1), 9-18

Improved technology allows for more accurate gait
analysis to increase awareness of nonoptimized prosthetic gait
patterns and for the manufacture of sophisticated prosthetic
components to improve nonoptimized gait patterns. However,
prescriptions... Read More about Transverse rotation and longitudinal translation during prosthetic gait - a literature review.

The biomechanical effects of the inclusion of a torque absorber and type of knee units on trans-femoral amputee gait (2002)
Journal Article

This paper reports on a pilot study
investigating the effects on the gait of two transfemoral
amputees of to the inclusion of a torque
