For control participants
--> Participants are within between 50 and 75 years of age
--> Participants are able to walk for at least 4 minutes for 6 subsequent trials, between trials 20 minutes of rest is given to prevent fatigue.;For participants with amputation
--> The participants have acquired a walking ability of degree C-F on the SIGAM mobility grade [24, 25], indicating, that they participants are able to walk a minimum of 50 meters.
--> The participants are able to walk for at least 4 minutes for 6 subsequent trials, between trials 20 minutes of rest if given to prevent fatigue.
--> During the last minute of the trial the participant should be able to walk without support.
--> Time since amputation is more than 1 year.
--> Participants are comfortable with and accustomed to walk with their prosthesis.
--> Abnormalities found in the resting ECG or blood pressure.
--> Problems noted by the physiatrist which could interfere with the results or the participants well being during the measurements.
--> Participant scoring less than 24 points out of the 30 that can be gained< 24/30 on the Modified Mini Mental State Examination questionnaire.
-->Neurological or musculoskeletal disorders which have an effect on the execution of gait other than disorders related to the amputation.
--> problems with the stump which could interfere with walking ability.
