Assessment Of Prosthetic Gait With Leg Length Discrepency Using Dynamic Leg Length Model
Therese E. Parr, BS
This work involves developing and assessing a predictive model that can aid in the prescription of component lengths for the thigh, shank, heel, and toe to encourage functional symmetry during gait. The model was validated and assessed with retrospective amputee data to show the dynamic effects of component adjustments and limb length inconsistencies.
Learning Objectives:
- debate pros/cons of current methods for prescribing and adjusting component lengths (e.g. thigh, shank, toe, and heel)
- describe the effects of adjusting joint positions and segment lengths on symmetry and overall gait compensations of transfemoral amputees
- theorize novel methods for using a standard anthropometric suggestion guide in clinical practice
Effects Of Microprocessor Knee Use In Early Rehabilitation
Sara J. Morgan, PhD, CPO
This pilot randomized controlled trial compared outcomes in participants with recent transfemoral amputation who received either a microprocessor knee or a non-microprocessor knee. Preliminary findings suggest potential benefits to microprocessor knee use in early rehabilitation, but results need to be confirmed with larger studies.
Learning Objectives:
- Describe the aim of the study and why it is important in prosthetics clinical care.
- Describe the results of the study in terms of performance-based and self-reported outcomes.
- Describe the clinical implications of this study.
Osseointegration After Intramedullary Lengthening
Anuj Chavan, B.MedSci (Hons)
This study provides the first report of patient outcomes of osseointegration for transfemoral amputees after lengthening using intramedullary nail.
Learning Objectives:
- Describe the indications for lengthening in amputees with short femoral stumps.
- Understand the outcomes of lengthening and osseointegration in patients with short femoral stumps.
- Understand the management of complications during lengthening and osseointegration of patients with short femoral stumps.
Temporospatial Changes Due To Adding Mass On A Transfemoral Prosthesis
Emily J. Hurst, MPO, CPO
OPERF/ABC Resident Travel Award Winner
Previous research has not fully addressed how the location of added mass on a transfemoral prosthesis may alter outcomes for transfemoral prosthetic users. Therefore, the aim of this study was to investigate how gait kinematics are impacted by the addition of a specified mass to a user's transfemoral prosthesis at three different locations. It was hypothesized that adding mass more distally will cause the greatest change in gait parameters when compared to a prosthetic user's baseline condition with no added mass.
Learning Objectives:
- Understand gait challenges faced by those with transfemoral limb loss
- Discuss how additional mass concentration on a prosthesis may impact gait speed and asymmetries
- Consider how mass concentration may impact prosthetic design choices
