Criteria for Advanced Prosthetic Foot Prescription
January 9, 2023 updated by: Jason Maikos, VA New York Harbor Healthcare System
The purpose of this study is to develop criteria for prosthetic foot prescription for Veterans and Service Members with transtibial limb loss.
The objectives are to: 1) Determine the appropriate functional outcome tests and measures to support the prescription of a type of Energy Storing and Returning (ESR) non-articulating, articulating or active plantarflexion prosthetic ankle-foot for a Veteran or Service Member with transtibial limb loss.
2) Correlate patient goals and subjective measures with objective data to determine the appropriate prosthetic ankle-foot category that will facilitate the greatest overall function to the user.
3) Develop criteria for the appropriate prescription of non-articulating ESR, articulating ESR, and active plantar flexion ESR ankle-foot units.

Participation Criteria
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
Eligibility Criteria
Ages Eligible for Study
18 years and older (Adult, Older Adult)

Genders Eligible for Study

Description
Inclusion Criteria:
- DEERS eligible Veteran or Service Member, or civilian with unilateral transtibial amputation
- Currently using an Energy Storing and Returning prosthetic foot with a well-fitting socket as a primary or back-up prosthesis
- Achieved a "Modified Independence" score on the Functional Independence Measure (FIM) for the locomotion mobility items
- Has a minimum clearance of 8 ¾ inches to accommodate all feet
Exclusion Criteria:
- Has active wounds/ulcers or significant musculoskeletal comorbidities on their intact limb that would impair their ability to participate in all functional outcome measures
- Has any comorbidity that results in rapid limb volume changes (i.e. end stage renal disease with dialysis),
- Weighs more than 275 pounds, the maximum product weight load
- Is unable or unwilling to comply with all research visits
- Has cognitive deficit(s) or mental health pathology limiting a subject's ability to participate fully in the study
- Women who are pregnant or plan to become pregnant during study activities. This will be determined by asking the participant if they are pregnant or if they believe that they may be pregnant. This question will only be asked at inclusion, as biomechanical changes will only be impacted if the woman is in the 2nd or 3rd trimester, and will not be impacted if the participant becomes pregnant while in the study.
- Poorly fitting socket
- Vision loss that requires use of an assistive device for gait
- Upper Limb Amputation

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Prosthetic Evaluation Questionnaire (PEQ) score for each prosthetic foot type
Time Frame: Once per week, at Week 1, Week 2, and Week 3 after enrollment
|
The PEQ is a self-report Visual Analog Scale questionnaires for persons with lower limb amputations who use a prosthesis.
It consists of 9 validated subscales.
They are used to evaluate the prosthesis and life with the prosthesis.
Most questions in the PEQ use a visual analog scale format.
Each visual analog scale is scored as a continuous numerical variable measured as the distance in millimeters from the left endpoint of the line to the point at which the respondent's mark crosses the line.
Each line is 100 mm long and is always measured from the left (0-100).
The questions are all worded so that a higher number (toward the right) will correspond with a more positive response.
Subscale scores are calculated by computing the average (arithmetic mean) of all the questions which make up that particular scale.
Only subscales are calculated.
A total combined score is not calculated.
|
Once per week, at Week 1, Week 2, and Week 3 after enrollment
|
Change in Short Form (SF)-12 for each prosthetic foot type
Time Frame: Once per week, at Week 1, Week 2, and Week 3 after enrollment
|
The SF-12 is a questionnaire used to measure the relationship between physical and mental health functioning and the social determinants of health.
It is a self-reported questionnaire, on a rating scale, called a Likert Scale.
The participant taking this questionnaire will check one response box per question.
Physical and Mental Health Composite Scores (PCS & MCS) are computed using the scores of twelve questions and range from 0 to 100, where a zero score indicates the lowest level of health measured by the scales and 100 indicates the highest level of health.
Age-specific mean difference score (difference score) is calculated and is the amount by which a person's score differs from their age group's mean score.
By looking at difference scores, it is clear whether a person is more or less healthy than other persons in his or her comparison group.
|
Once per week, at Week 1, Week 2, and Week 3 after enrollment

Time Frame: Once per week, at Week 1, Week 2, and Week 3 after enrollment

OPUS is a set of self-report instruments that assess functional status, quality of life, and satisfaction with devices and services that can be used in an orthotics and prosthetics clinic.
The OPUS Health Quality of Life Score is the sum of the scores for the 23 items (0 - 92).
The OPUS lower extremity total score is the sum of the scores for the 20 items (0 - 80).
OPUS Satisfaction With Device Score is the sum of the scores for items 1-11 (11 - 55).
Satisfaction With Services Score is the sum of the scores for items 12-21 (10 - 50).
A higher score indicates a better outcome for all measures.
