There has been a shift in rehabilitation medicine from conventional evaluation procedures towards more quantitative approaches. However, up to now, a quantitative evaluation procedure for upper limb prostheses that is applicable outside of the laboratory or clinical environment has not been established. The requirement for such a procedure arises from the findings of a number of recent studies suggesting...
Increased step time variability, particularly on an irregular surface, has been associated with impaired mobility function and a variety of diseases. However the biomechanical necessity, or advantage, of increasing step time variability has not been identified.We performed a secondary analysis of gait data previously obtained on 42 subjects age 50 or older with neuropathy who walked on smooth and...
This work investigates arm acceleration as a control signal for Functional Electrical Stimulation (FES) of the upper limb during reaching and grasping. We segment the reach and grasp motion into phases and present an Artificial Neural Network (ANN) approach that estimates the phase of the reaching cycle from accelerometer signals. We then select the stimulator command that maximizes successful triggering...
