the aim of the proposed study is to assess the load of anatomical hip, knee and ankle joints in people that use one leg prosthesis for sprinting. The loading of both ipsi- (if present) and contralateral joints will be assessed.

Outcome measures
Primary outcome
Participants in the study will walk, run and sprint at maximal velocity over an
instrumented walk way. Net joint moments in available ipsilateral and
contralateral joint will be calculated. In addition muscle activation pattern
of available muscles in lower leg, thigh and gluteal region will be registered.
Moreover, joint angles and spatiotemporal gaitcharacteristics like step length
and frequency will be determined.
Secondary outcome

Background summary
Athletes that due to a (lower) leg amputation use a prosthesis for sprinting
seem to have an increased risk of hip joint arthrosis. It is feasible that
changes in the loading of joints during sprinting underly this increased risk.
Study objective
the aim of the proposed study is to assess the load of anatomical hip, knee and
ankle joints in people that use one leg prosthesis for sprinting. The loading
of both ipsi- (if present) and contralateral joints will be assessed.
Study design
observational, experimental, cross-sectional pilot study
Study burden and risks
For an individual participant the tests will last maximally 3 hours, this
includes preparation time. During the test the participants will be asked to
walk three times at a speed of 1.2m/s, to run three times (3.5 m/s) and to
perform three maximal sprints. In athletes with an amputation both limbs will
be measured. In addition they will perform the run and sprint tests with two
types of protheses, a stiffer and a less-stiffer prosthesis. For the walk tests
subjects will use their ADL-prosthesis, for running and sprinting they will use
a sports prothesis. Consequently they will walk or run 30 times over the 20m
measurement track. Able-bodied athletes will be measured on their dominant leg
only, they will run shod and bare foot. Consequently they will walk or run 18
times over the track. This will not exceed the level of activities that these
participants reach during daily life. So it can be concluded that the intensity
is not extreme and the study does not provide any additional risk.
