EMG Pattern Recognition Control of the DEKA Arm: Impact on User Ratings of Satisfaction and Usability.

The DEKA Arm has multiple degrees of freedom which historically have been operated primarily by inertial measurement units (IMUs). However, the IMUs are not appropriate for all potential users; new control methods are needed. The purposes of this study were: 1) to describe usability and satisfaction of two controls methods-IMU and myoelectric pattern recognition (EMG-PR) controls-and 2) to compare ratings by control and amputation level.

Systematic Review of Measures of Impairment and Activity Limitation for Persons With Upper Limb Trauma and Amputation.

Objective: (1) To identify outcome measures used in studies of persons with traumatic upper limb injury and/or amputation; and (2) to evaluate focus, content, and psychometric properties of each measure.

Data Sources: Searches of PubMed and CINAHL for terms including upper extremity, function, activities of daily living, outcome assessment, amputation, and traumatic injuries.

Study Selection: Included articles had a sample of ≥10 adults with limb trauma or amputation and were in English.
