Eligibility
Inclusion criteria
Inclusion criteria: This study includes healthy participants. A healthy participant is defined as a person who: Does not have a foot deformities like hallux valgus, Charcot foot, severe pes planus or pes cavus or a clubfoot. Does not have a medical history of foot surgeries Has no current foot pain or functional limitations at rest, or when walking or standing on bare foot Has no neurological or systemic conditions affecting foot structure or sensory and motor functions of the foot (e.g. diabetes mellitus, rheumatoid arthritis, neuropathies) Has a normal mobility and does not use walking aids. Does not have vascular conditions affecting circulation in the foot. The investigators expect to have a normal pressure plate profile. A normal pressure plate profile is characterized by: A plantar pressure distribution consistent with a physiological gait pattern, with the highest pressure peaks located under the heel, the first and fifth metatarsals, and the hallux. A smooth roll-off of the foot, without extreme lateralization or medialization of the pressure distribution. Other inclusion criteria to be eligible to participate in this study are: Age: Between 18 and 65 years Sex: Both biological female and male participants will be included. Informed Consent: the participant must be able to understand and provide informed consent regarding the nature and goals of the study.
Exclusion criteria
Exclusion criteria: A potential subject who meets any of the following criteria will be excluded from participation in this study: Participants who do not wish to be informed about unexpected medical findings Foot Deformities: Presence of significant foot deformities. Neuropathy: Any history of neuropathy or conditions affecting foot sensation. Foot Surgery: History of foot surgery that may alter anatomical or biomechanical characteristics. Amputation: Any amputation of (part of) the lower extremities. Skin Conditions: Any abnormal skin conditions, including ulcers or open wounds on the foot. Medical Implants: Presence of any medical implants or devices that may interfere with MRI imaging. Inability to stand for a period of 5 minutes. Pregnancy: The exclusion of pregnant women is not only due to the safety concerns of contrast agents, as no contrast is used in the MRI scans for this study. Hormonal changes that can affect foot structure, potentially influencing result interpretation, were also considered. MRI Safety: Any other condition that would make MRI unsafe or unreliable. Height > 200 cm Weight > 150 kg Can people with flat feet or orthotics participate? People with mild flat feet (pes planus) or high arches (pes cavus) can participate if they do not have functional complaints or pain at rest or when walking or standing on bare foot. In such cases, their pressure profile is considered part of the natural variation within a healthy population. If abnormal pressure distributions are measured, these can be analysed as a subgroup within the healthy participants. People who wear orthotics can only participate if they exhibit a physiological gait pattern and pressure distribution without orthotics during the measurement and if they have no functional complaints or pain at rest or when walking or standing on bare foot.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main study parameters are (1) a workflow that creates a database of WB and non-WB MRI scans from the feet of 20 healthy subjects; (2) the difference in foot morphology between WB and non-WB conditions; (3) validation of the FEM by using the input of the healthy feet to match and compare the PP with empirical data of a pressure plate. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary study parameters are (1) a relatively simple initial SSM of the foot that is developed by using the foot data of the 20 healthy subjects; (2) the plantar pressure of the healthy foot. | — |
