Pilot data that resulted in extramural funding and publications:
Qualitative results from the OPERF funded study entitled “Defining success in lower limb prosthetics: Which outcomes matter most?” were used as evidence to support the need for development of a new population-specific outcome measure to assess grief after amputation. This grant proposal was funded through NICHD as a five-year K01 award of $624,992 entitled, “Optimizing health outcomes by improving measurement of grief after amputation with a health equity approach.” This project began Jan 1, 2025.
Qualitative research, such as was funded under OPERF, is essential to inform subsequent directions for research inquiry particularly when the intention is to conduct research that is grounded in the priorities of the limb loss community. While this data may not be traditionally considered pilot data, qualitative findings are essential for patient-centered research.

Trunk Muscle Characteristics and their Association with Balance, Functions, and Participation among Individuals with Amputations
This study found spinal muscle impairments, i.e., reduced muscle activity and increased intramuscular fat, are associated with lower-limb amputation, and that findings may differ depending on the amputation level, i.e., transfemoral- versus transtibial. Results will inform the development of future, longitudinal work evaluating whether spinal impairments predict physical function and community participation, and should be considered as potential modifiable factors in future interventional studies among adults post-amputation.

ACCEL Pilot – Somatosensory Dysfunction, Prosthetic Use, and Function in Adults with Limb Loss (Sions)
With advances in prosthesis design and innovative rehabilitation interventions, we may improve outcomes for patients who experience a limb amputation. This study evaluated changes in somatosensory function post-amputation that might impact prosthesis fit, technology, and post-amputation outcomes. We found adults with non-dysvascular, transtibial-level amputation had similar vibration detection to controls with intact limbs indicating vibration is preserved in the amputated region post-amputation, and may be a mechanism for delivering prosthetic feedback. A unique relationship was found between vibration perception and balance post-amputation, in that this relationship was not found in controls; capitalizing on this relationship may be a mechanism for mitigating falls post-amputation. Further, adults with post-amputation pain have greater amputated region pain sensitivity, per pain-pressure threshold testing, as compared to pain-free peers and controls with intact limbs, indicating peripheral sensitization persists after limb healing. Peripheral sensitization may help explained reduced prosthesis comfort and use among adults with post-amputation pain, as compared to peers without post-amputation pain, and may be a critical target in post-amputation rehabilitation.
