Sensory feedback is largely unavailable for upper-limb amputees with conventional prostheses. The current study investigated four fundamental issues relating to an external vibrotactile stimulation modality for prosthetic hand force feedback: optimal...
Cross-Sectional Study of Residuum Measures during Gait and Work-Related Activities in Men with Transtibial Amputation Resulting from a Traumatic Event

Most adults with transtibial amputation due to trauma (TTAT) are work-eligible, yet are disproportionately unemployed. Inappropriate residuum muscle activity and load at the distal residuum-prosthetic socket interface (RSI) during prosthetic use are ...
Effects of Adaptation to a Functionally New Prosthetic Lower-Limb Component: Results of Biomechanical Tests Immediately after Fitting and after 3 Months of Use

Siegmar Blumentritt, PhD
Ten established transfemoral amputees completed biomechanical tests after they had been fitted with a new prosthetic knee joint. The required adaptation phase is considered to be completed when the test result is no longer influenced by the patients'...

Bracing and patellar taping are common interventions for patellofemoral pain (PFP) reducing pain by between 56% and 80%. To date there have been no comparative investigations into the effect of patellofemoral tape and patellofemoral brace on knee mec...
Athletic Assistive Technology for Persons with Physical Conditions Affecting Mobility

Hugh Herr, BA, MS, PhD
Recent advances in technology have allowed athletes with physical conditions to perform at increasingly high levels. Though much progress has been achieved, technology for "disabled" athletes must be far advanced to allow them to reach and surpass th...
Use of a Powered Versus a Passive Prosthetic System for a Person with Bilateral Amputations during Level-Ground Walking
Erik J. Wolf, PhD
Alison L. Pruziner, DPT
Persons who have suffered bilateral lower-limb amputations, especially transfemoral amputations, must use biomechanical compensations to ambulate, which produce abnormal loads on the body and may reduce efficiency. In this case study, a patient with ...
