Biceps Brachii Muscle Innervation Zone Location in Healthy Subjects Using High-Density Surface Electromyography

Among the sequelae of central nervous system injury is spasticity which is difficult to manage in rehabilitation. Current treatments consider the administration of the botulinum toxin. However, results have proved highly variable in terms of effectiveness, attributable to the distance between the in...
