   Abstract : The use of implantable electrodes has been long thought as the solution for a more natural control of artificial limbs, as these offer access to long-term stable and physiologically appropriate sources of control, as well as the possibility to elicit appropriate sensory feedback via neurostimulation. Although these ideas have been explored since the 1960’s, the lack of a long-term stable human-machine interface has prevented the utilization of even the simplest implanted electrodes in clinically viable limb prostheses.

   Abstract : Promising developments are currently ongoing worldwide in the field of neuroprosthetics and artificial limb control. It is now possible to chronically connect a robotic limb to bone, nerves and muscles of a human being, and use the signals sourced from these connections to enable movements in the artificial limb.

5. 3. Motion Analysis and Postural Stability of Transtibial Prosthesis Users

   Author : David Rusaw; Göteborgs universitet; []
   Keywords : Artificial limb; balance; electromyography EMG ; motion analysis; postural stability;

   Abstract : The AIMS of the thesis were to critically evaluate motion analysis methods used during investigations of transtibial prosthesis users, and to propose improvements to these methods. Additionally, the aim was to evaluate if vibratory feedback could be used to improve postural stability in transtibial prosthesis users and how being a prosthesis user influenced muscular response to postural perturbations.

6. 4. Benefits and use of myoelectric arm prostheses : outcomes, influencing factors and experiences

   Author : Cathrine Widehammar; Liselotte Hermansson; Kajsa Lidström-Holmqvist; Ingvor Pettersson; Kristin Østlie; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; upper limb; amputation; artificial limbs; rehabilitation; occupational therapy; environment; qualitative methods;

   Abstract : People with acquired upper limb loss or congenital limb reduction deficiency are often offered a myoelectric prosthesis to compensate for the missing hand. A common problem is the non-use of prostheses, and lack of training has been suggested as a reason for this. READ MORE

7. 5. Electromyogram Signal Enhancement and Upper-Limb Myoelectric Pattern Recognition

   Author : Sara Abbaspour; Maria Lindén; Christian Antfolk; Mälardalens högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

   Abstract : Losing a limb causes difficulties in our daily life. To regain the ability to live an independent life, artificial limbs have been developed. Hand prostheses belong to a group of artificial limbs that can be controlled by the user through the activity of the remnant muscles above the amputation. READ MORE
