Yes / Background: Individuals with lower-limb amputation can use running specific prostheses (RSP) that store and
then return elastic energy during stance. However, it is unclear whether varying the stiffness category of the
same RSP affects spring-mass behaviour during self-selected, submaximal speed running in individuals with
unilateral transtibial amputation.
Research question: The current study investigates how varying RSP stiffness affects limb stiffness, running performance,
and associated joint kinetics in individuals with a unilateral transtibial amputation.
Methods: Kinematic and ground reaction force data were collected from eight males with unilateral transtibial
amputation who ran at self-selected submaximal speeds along a 15 m runway in three RSP stiffness conditions;
recommended habitual stiffness (HAB) and, following 10-minutes of familiarisation, stiffness categories above
(+1) and below (-1) the HAB. Stance-phase centre of mass velocity, contact time, limb stiffness’ and joint/RSP
work were computed for each limb across RSP stiffness conditions.
Results: With increased RSP stiffness, prosthetic limb stiffness increased, whilst intact limb stiffness decreased
