“…In addition, the VE method obtained a similar level of CV (2.1%) to another published aerodynamic field test method that was also intended for prosthetic level changes in componentry [10]. This suggests that despite limb to limb asymmetry being a typical characteristic of cyclists with lower-limb absence [2], the very high level of correlation and low data variability in this study suggests that either test is recommended for the analysis of cyclists that possess a lower-limb amputation.…”

“…The opportunities for individuals with an amputated limb using cycling as a medium for physical activity have developed from one of purely recreation [1] into more extreme pursuits such as competitive cycling [2] or triathlon [3]. However, to undertake cycling whilst possessing any level of lower-limb amputation will likely require some form of specialised prostheses to be developed [4].…”

“…Furthermore, the ability to optimise the performance of such individuals undertaking competitive cycling is desirable for sporting events such as the Paralympic Games. However, a recent systematic review revealed that there is extremely limited peer-reviewed literature to help inform the clinicians with the design of either adaptive or assistive technology for this purpose [2].…”

Lower-limb amputees typically require some form of prosthetic limb to ride a bicycle for recreation or when competing. At elite-level racing speeds, aerodynamic drag can represent the majority of the resistance acting against a cyclists forward motion. As a result, the reduction of such resistance is beneficial to an amputee whereby the form and function of the prosthetic limb can be optimised through engineering. To measure the performance of such limbs, field testing provides a cost effective and context specific method of aerodynamic drag measurement. However, few methods have been formally validated and none have been applied to amputees with lower-limb amputations. In this paper, an elite level para-cyclist wore two different prosthetic limb designs and had their total aerodynamic drag of a wind tunnel reference method statistically correlated against a velodrome-based virtual elevation field test method. The calculated coefficient of variation was in the range of 0.7-0.9% for the wind tunnel method and 2-3% for the virtual elevation method. A 0.03m 2 difference was identified in the absolute values recorded between the two methods. Ultimately, both methods exhibited high levels of precision, yet relative results to each other. The virtual elevation method is proposed as a suitable technique to assess the aerodynamic drag of amputee para-cyclists.

We performed musculoskeletal simulations to provide information on the effects of riding position and bicycle geometry on pedaling with a transfemoral prosthesis. Sixty-four models and their corresponding kinematics in one pedaling cycle were generated from the baseline one-leg cycling model by varying one of the six variables (seat height, seat-tube angle, crank length, pelvic tilt, anteroposterior seating position, and thigh length relative to the leg). Induced acceleration analysis was performed to compute the potentials of the residual hip muscles for crank rotation in each model.The simulation results quantified the effects of each variable on the hip and knee kinematics and muscle potential during a pedaling cycle; seat height, crank length, and pelvic tilt were the primary candidates for bicycle fitting considering their accessibility and simple effects on the joint kinematics and muscle potential. The seat-tube angle (similar to pelvic tilt) and the anteroposterior seating position (similar to seat height and seat-tube angle) seemed to have an effect similar to the other variables and thus can be reserved for fine-tuning after gross fitting of the bicycle. Although not considered for adjustment, considering the effects of the thigh length could help as it affects hip kinematics and muscle potentials.

Cycling with an amputation

Abstract: This review study established the historical strategy and content of cycling with an amputation and identified the existing research themes. This will assist in summarising the current level of knowledge and help signpost such work in the future.
