Biomechanical Evaluation of a Novel, Compliant Low Profile Prosthetic Foot
June 12, 2024 updated by: Little Room Innovations, LLC
The investigators have developed a novel layered low-profile prosthetic foot that is able to provide enhanced compliance without sacrificing strength for individuals with transtibial amputation who have long residual limbs.
It is hypothesized that the proposed prosthesis will offer similar benefits to these individuals as comparable higher profile prostheses offer users with shorter residual limbs.
The primary goal of this Phase I proposal is to assess the degree to which the proposed prosthesis can provide benefits to prosthesis users in this population, along with characterizing the degree to which the novel prosthesis emulates its taller counterparts.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Layered Low Profile Foot (LPF) vs. Prescribed Ankle
In this arm, subjects will first test the LPF and then complete the tests with their prescribed ankle.
|
The layered LPF is a novel low-profile prosthetic foot that provides compliant behavior while simultaneously exhibiting high mechanical strength.
Other Names:
The prescribed ankle is the prosthetic ankle that the subject wears for daily use.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Total Energy Stored (TES)
Time Frame: through study completion, an average of 1 day
|
TES is the amount of energy absorbed by the ankle joint during early and middle stance.
It is the integral of the product of joint torque and angular velocity, as determined through inverse dynamics.
|
through study completion, an average of 1 day
|
Ankle Range of Motion (ROM)
Time Frame: through study completion, an average of 1 day
|
ROM is the difference between the maximum and minimum ankle angles measured in a gait cycle.
|
through study completion, an average of 1 day
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Ankle Quasi-Stiffness (AQS)
Time Frame: through study completion, an average of 1 day
|
AQS is a measure of joint deformation under an applied load.
It is extracted from the torque-angle relationship during walking determined through inverse dynamics.
|
through study completion, an average of 1 day
|
Walking Speed
Time Frame: through study completion, an average of 1 day
|
This is the linear rate of change of position when a person walks, typically given in m/s.
|
through study completion, an average of 1 day
|
Rollover Shape from Motion Capture
Time Frame: through study completion, an average of 1 day
|
Rollover shape is a physical shape that is kinematically equivalent to the contact points of a deformable shape moving through a given loading pattern.
Rollover shape is measured by combining the readings of a force plate with the kinematic data obtain from motion capture.
|
through study completion, an average of 1 day
|
Device Satisfaction survey of the Orthotics and Prosthetics Users Survey (OPUS)
Time Frame: through study completion, an average of 1 day
|
The OPUS is a self-report questionnaire for determining quality, maintaining awareness of improvement in activities, evaluating changes in functional status, and assessing satisfaction with devices and services.
Scores on the questionnaire range from Strongly Agree to Strongly Disagree.
Strongly Agree is associated with the best outcomes in the survey.
|
through study completion, an average of 1 day
