Effect of glenohumeral forward flexion on upper limb myoelectric activity during simulated mills manipulation; relations to peripheral nerve biomechanics

BACKGROUND It is generally accepted that muscles may activate via the common nociceptive flexion reflex (NFR) in response to painful stimuli associated with tensile or compressive forces on peripheral nerves. Following the basic assumption that the radial nerve may be stressed around the elbow during the execution of the Mills manipulation, two positions considered to have different mechanical ...

Biomechanics of Upper Limb Orthoses

INTRODUCTION Functional impairment of [parts of] the upper limb has many different expressions. Sound biomechanical analysis is at the basis of the management of the physical challenges involved. An outline of the basics of a mechanical systems approach is presented below. Orthoses are among the many treatment options for upper limb impairments. An orthosis can be defined as a mechanical constr...

Myoelectric Prosthetic Components for the Upper Limb

When Policy Topic is covered Myoelectric upper limb prosthetic components may be considered medically necessary when the following conditions are met:  The patient has an amputation or missing limb at the wrist or above (forearm, elbow, etc.); AND  Standard body-powered prosthetic devices cannot be used or are insufficient to meet the functional needs of the individual in performing activitie...

Visual Cues to Improve Myoelectric Control of Upper Limb Prostheses

The instability of myoelectric signals over time complicates their use to control highly articulated prostheses. To address this problem, studies have tried to combine surface electromyography with modalities that are less affected by the amputation and environment, such as accelerometry or gaze information. In the latter case, the hypothesis is that a subject looks at the object he or she inte...
