Achtergrond van het onderzoek
This study evaluates the performance of a new powered knee prosthesis, the Reboocon IntelLeg Knee, compared to the current state of the art (i.e. passive auto-adaptive prostheses). The study will be evaluated on 10 unilateral transfemoral amputees. The evaluation will be based on questionairres (parts of the Prosthesis Evaluation Questionairre and the Borg RPE score), biomechanical measures (kinematics, kinetics and EMG) and standardized tests for prostheses (e.g. L-test).
Doel van het onderzoek
The study is performed to verify if the Reboocon IntelLeg Knee has benefits compared to passive microprocessor controlled knees. We believe the IntelLeg Knee
- improves symmetry (kinematics + kinetics)
- reduces the cost of transport for walking (metabolic energy consumption)
- reduces the rate of perceived effort (Borg RPE score)
- improves scores on standardized tests, such as the hill assessment index (HAI), the stair assessment index (SAI) and the L-test.
Onderzoeksopzet
All data is recorded during the execution of movement tasks.
Onderzoeksproduct en/of interventie
Study is designed as an A-B-A study, in which A is the subject's daily use prothesis and B the Reboocon ILK.

Belangrijkste voorwaarden om deel te mogen nemen (Inclusiecriteria)
- Aged between 18 and 65.
- Weight below 100 kg.
- Body length between 1.51 and 1.95 m.
- 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 limited 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.
- Willing to commit to a series of 1 or 2 training sessions of approximately 1.5 hours to get adjusted to the IntelLeg Knee.
- Current prosthesis is a passive microprocessor controlled knee.
Belangrijkste redenen om niet deel te kunnen nemen (Exclusiecriteria)
- Not willing to consent to participate in the study.
- Other musculoskeletal problems influencing walking ability.
- Stump problems/bad socket fitting
