    Sammanfattning : An investigation of improvements of myoelectric prostheses has been undertaken. The primary aims of this thesis were (1) to generate an accurate prediction of as many hand movement as possible, (2) to produce a training setup for subjects allowing intuitive and instant control over multiple movements, and (3) to reduce the training cycle for the control system to a maximum of a couple of minutes to enable optimizations, e.

  3. 2. The Assessment of Capacity for Myoelectric Control : Psychometric evidence and comparison with upper limb prosthetic outcome measures

    Författare :Helen Lindner; Liselotte Hermansson; Ann-Christin Eliasson; Ann Langius Eklöf; Helena Burger; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; capacity; comparison; icf; myoelectric control; psychometric evidence; upper limb prosthesis;

    Sammanfattning : Evaluation of outcomes using validated prosthetic outcome measures (OMs) is a current priority in upper limb (UL) prosthetics, and OMs with psychometric evidence toward UL prosthesis users are thus necessary. The “Assessment of Capacity for Myoelectric Control” (ACMC) is a tool that assesses the ability to control a myoelectric prosthetic hand. LÄS MER

  4. 3. On the Utility of Representation Learning Algorithms for Myoelectric Interfacing

    Författare :Alexander Olsson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; Machine Learning; Deep Learning; Feature Learning; Biosignal Processing; Gesture Recognition; Muscle-Computer Interfaces; Myoelectric Control; Upper-Limb Prosthetics;

    Sammanfattning : Electrical activity produced by muscles during voluntary movement is a reflection of the firing patterns of relevant motor neurons and, by extension, the latent motor intent driving the movement. Once transduced via electromyography (EMG) and converted into digital form, this activity can be processed to provide an estimate of the original motor intent and is as such a feasible basis for non-invasive efferent neural interfacing.

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Upper limb reduction deficiencies in Swedish children : classification, prevalence and function with myoelectric prostheses

    Författare :Liselotte M. N. Hermansson; Ann-Christine Eliasson; Ann Nachemson; Karolinska institutet Institutionen för kvinnors och barns hälsa; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; children; upper limb; deficiency; register validation; scoliosis; arm prosthesis; measurement; occupational therapy; psychopathology; depression; Medicine; Medicin; Children; upper limb; deficiency; register validation; scoliosis; arm prosthesis; measurement; occupational therapy; psychopathology; depression;

    Sammanfattning : Upper limb reduction deficiency (ULRD) is a rare condition that has been known ever since the 6th century B.C. This is a lifelong deficiency which in an afflicted child can lead to practical limitations, social restrictions and physical problems. LÄS MER
