N.v.t. Amputation Individuals without an amputation
Conditions
Interventions
Subgroup of individuals with an amputation (n=5) will be walking on an active
prothesis during train and measurement sessions. This group also takes the
prothesis home between the trainingsessions f

Eligibility
Age
18 Years to 99 Years
Inclusion criteria
Inclusion criteria: Individuals without an amputation - Aged 18 or above. - Able to perform low to moderate vigorous physical activity for a duration of 3 hours including breaks. , Individuals with an amputation - Aged 18 or above. - Unilateral transfemoral amputation or knee disarticulation. - Functional level from K2 to K4. o Level 2: The patient has the ability or potential for ambulation with the ability to traverse low level environmental barriers such as curbs, stairs, or uneven surfaces. Typical of the community ambulator. o Level 3: The patient has the ability or potential for ambulation with variable cadence. Typical of the community ambulatory who has the ability to traverse most environmental barriers and may have vocational, therapeutic, or exercise activity that demands prosthetic utilization beyond simple locomotion. o Level 4: The patient has the ability or potential for prosthetic ambulation that exceeds basic ambulation skills, exhibiting high impact, stress, or energy levels. Typical of the prosthetic demands of the child, active adult, or athlete. - Able to perform low to moderate vigorous physical activity for a duration of 3 hours including breaks. - At least one year after amputation.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary study parameter is the misclassification rate of a classifier. The misclssification rate of the classifier that is based on biplor EMG and HD-EMG will be compared. In addition, misclassification rates of classifiers developed with different techniques will also be compared. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secundary study parameters are: - The misclassification rate for unsupervised algorithms Unsupervised algorithms will also be compared to supervised algorithms. To determine - - The effect of repeated measurements on the robustness of the classifier and regressor - The effect of additional sensor information on misclassification rate by using the raw IMU sensor data from the Xsens suit. This information is recorded during measurements anyway, as Xsens uses this information in their biomechanical model to reconstruct movements. - The effect of prosthesis type on the robustness of the classifier | — |
