OBJECTIVE To determine if the use of botulinum toxin during cheiloplasty could help in the management of tension at the surgical wound level. INTERVENTIONS Five children younger than six months of age, who were born with complete cleft lip and palate, were treated with a dose of 10 units of botulinum toxin injected into the upper lip during surgery. Before the surgery, an electromyographic st...

OBJECTIVES To determine if the muscle force and electromyographic activity in the scapular rotators of overhead athletes with impingement symptoms showed differences between the injured and non-injured sides. METHODS Isokinetic peak force was evaluated during protraction and retraction of the shoulder girdle, with simultaneous recording of electromyographic activity of the three trapezius mus...

Electromyographic control is a technique that involve with the detection, processing and classification of the electromyography signal that could be applied in human-assisting robots, prosthesis application or rehabilitation devices. This paper reviews recent research and development electromyographic control systems with an emphasis on pattern recognition control for prosthesis application. Va...

Changes in electromyographic (EMG) parameters are used to evaluate timing, amplitude, and fatigue of muscle actions during movement. Little published data describe the reliability and precision of multiple EMG parameters, how these parameters compare to one another, and how these parameters vary between muscles. The purpose of this study was to determine the reliability and precision of four EM...
