Anahid Kulwicki, PhD, RN, FAAN
Mario De la Rosa, PhD
This study aimed to describe the functional and psychosocial impact of prostheses users who suffered a traumatic lower-limb amputation after the devastating 2010 earthquake in Haiti. The Trinity Amputation and Prosthesis Experience Scale (TAPES), and...
On the Suitability of Integrating Accelerometry Data with Electromyography Signals for Resolving the Effect of Changes in Limb Position during Dynamic Limb Movement
Ashkan Radmand, MSc
Erik Scheme, PhD
Kevin Englehart, PhD
Electromyogram (EMG) pattern recognition has long been investigated as a method of improving the control of powered upper-limb prostheses. However, several factors have recently been identified that affect the robustness of EMG pattern recognition. B...
Optimization of Important Relief Areas in Prosthetic Socket for Below-Knee Amputees Using Design of Experiment and Finite Element Model
Gabi Nehme
Saeed Ghalambor, PhD
There is a need in developing countries to investigate new methods for designing and optimizing sockets to provide comfort and satisfaction for transtibial amputees. In this study, socket designs were investigated and optimized using finite element m...
Stress Reduction in the Residual Limb of a Transfemoral Amputee Varying the Coefficient of Friction
Vanessa Restrepo, BSc
Junes Villarraga, PhD(c)
José Pavón Palacio, PhD
A finite element computer model was used to validate the relationship between the friction coefficient and shear stresses and pressures obtained at the socket/residual limb interface for four individuals with transfemoral amputation. It was demonstra...
Thermal Conductivities of Commercially Available Prosthetic Materials
Christina M. Webber, MS
Mena R. Klittich, BS
Ali Dhinojwala, PhD
Brian L. Davis, PhD
Current commercially available prosthetic liners and sockets insulate the residual limb, raising the temperature and causing excessive sweating. This may lead to numerous dermatologic conditions when coupled with the atypical loading of the residual ...
Potential Relationships among Foot Orthoses Use, Physical Activity, and Functional Level: Foot Orthoses Prescription and Application for the Obese
Christopher Kevin Wong, PT, PhD, OCS
Rich Weil, MEd, CDE
Erin Zoch, PT, DPT
Because reduced physical activity and functional levels associated with obesity may be associated with orthopedic conditions, foot orthoses have been recommended within the conservative care for people with obesity. However, little evidence supports ...
Immediate Influence of Carbon Composite Ankle-Foot Orthoses on Balance and Gait in Individuals with Peripheral Neuropathy: A Pilot Study
Kimberly Edginton Bigelow, PhD
Kurt Jackson, PT, PhD, GCS
Currently limited data exist supporting the use of ankle-foot orthoses (AFOs) on improving balance and gait in individuals with peripheral neuropathy (PN) and no studies have evaluated the effects of carbon composite AFOs in this population. The prim...
