Current solutions for the control of active upper-limb prostheses are mostly based on
EMG signals acquisition and processing and on electronic switches. Even though efficient for
most clinical cases, these solutions can ...
Gruppioni, E.; Chiossi, M.; Troncossi, M.; Cutti, A.G.; Davalli, A.; Parenti-Castelli, V.(Myoelectric Symposium, 2008)
INAIL and DIEM prototyped a new externally-powered prosthetic shoulder developed for
interscapulothoracic and first-proximal trans-humeral amputees. The articulation consist of
two connected powered joints that allow the ...
Williams, T. Walley, III(Myoelectric Symposium, 2008)
The typical problem patient has a transhumeral amputation 30 to 60 mm below the axilla. No
matter how well the socket is made, the moment arm in the socket is too little to sustain the four
foot-pound torque of a typical ...
The use of myoelectric command is often difficult to apply to congenital pathologies
of the upper limb, which alternative solutions such as pressure sensors or common
microswitches are often used. In such cases, prosthesis ...
Electrically actuated hand prostheses have the disadvantage of a high prosthetic
mass, a slow cycle time, vulnerability, and an excessive volume. Pneumatical actuation
can overcome these disadvantages. To demonstrate the ...
Sensinger, Jonathon W.; Weir, Richard F.(Myoelectric Symposium, 2005)
Commercially available prosthetic elbows have stiff actuators (motors) that are only
capable of motion (position or velocity) control. In an attempt to mimic human physiology while
accommodating prosthetic demands, a ...
Prosthesis control for persons with very short (axilla level) transhumeral (VSTH) amputation can be challenging. Due to the short lever arm, fully body-powered options are often not possible due to the lack of available ...
Transradial amputation implies the loss of the wrist. It therefore also implies the loss of the ability to do flexion/extension and radioulnar deviation as well as the forearm’s ability to rotate the wrist (prosupination). ...
The control of prostheses, both externally powered and body powered, increases in complexity with higher levels of amputation. The externally powered prosthesis has a limited number of options for controlling multiple ...
Williams, T. Walley III(Myoelectric Symposium, 2005)
Powered prostheses have come a long way in the last twenty five years. A good way to track this activity is simply to review the proceedings of the Myo-Electric Controls (MEC) conferences that have been held during that ...
