Study Location
University of Maryland – College Park, MD
Research Objective
To determine if, in comparison to using a standard socket-based transfemoral prosthesis, an osseointegrated prosthesis reduces the metabolic cost of walking, improves the symmetry of walking gait and/or reduces loading of the intact limb and lower back
Eligibility Criteria
We are seeking individuals with unilateral (single leg) above-knee limb loss who walk with a prosthetic limb, either a traditional socket-based prosthesis or an osseointegrated (bone-anchored) prosthesis.
Additional eligibility criteria are:
- Must be between 18-65 years of age
- Must not be diagnosed with hypertension or metabolic syndrome
- At least 18 months since most recent amputation or revision surgery
- Must be cleared medically to walk with no assistance other than a prosthesis
- Must not have any major chronic issues other than limb loss that affect walking ability
- Must have at least six months experience with current prosthesis used for walking
- Must be assigned a K-level 3 or 4
Compensation
- Participants receive $500 cash immediately upon completing the study.
- Additional lodging and travel compensation is available (some restrictions apply)
