Cervical spine injuries present with dysfunctions of the respiratory system characterized by: a reduction in forced vital capacity, ineffective cough, decreased peak expiratory and speech problems. Speech therapy intervention using an exercise program improves the intensity of the voice and fluency, the objective of this study was to determine the effect of electrotherapy in abdominal muscles on respiratory capacity proportional to speak in cervical injuries. We studied 60 people with chronic traumatic cervical spinal cord injury and restrictive breathing; they were divided in two groups: experimental (n=30) and control (n=30). Control group received speech therapy exercises and the experimental group received speech therapy and electrotherapy in abdominal muscles prior to the workout. Patients were assessed before and after application of the treatment with the following variables: forced vital capacity, peak expiratory flow, maximum phonation time, reading the words of two syllabes, vocal intensity and rate of speech disabilities. Two groups showed significant improvement in speech therapy variables evaluated after treatment (p ≤0.05). However, the use of electrical stimulation significantly increased the recovery of variables: vocal intensity (p =0.0485) and peak expiratory flow (p =0.0000) and both variables showed positive correlation [F (1, 28)=7.5478, p <0.01]. Conclusions: electrotherapy in abdominal muscles is beneficial for the improvement of peak expiratory flow and vocal intensity. Peak expiratory flow demonstrated to be a predictor of vocal in tensity.

La Memoria de Trabajo y su relación con otras funciones cognitivas en la Enfermedad de Parkinson.
Parkinson’s Disease (PD) is a neurological illness due to degeneration of the dopaminergic neurons of the nigro-striatal pathway. Each of the five frontal-subcortical circuits contributes in a different way to PD’s symptoms. The clinical manifestations are variable; they include non cognitive deficits like: rigidity, tremor, bradykinesia, and other motor deficits like hypomimic (mask-like face), hypophonia, dysarthria, dystonia and abnormal postures among others. The emotional disorders in PD include depression and anxiety. The frontotemporal dementia in PD has been described. The neuropsychological examination of the PD patient is done considering whether the main symptoms are bradykinesia and rigidity, since these patients show more severe cognitive decline. We must examine the attention, which is between the normal limits in simple tasks, but it shows deficits in more complex tasks; memory and learning are disturbed, orientation is intact; in verbal functions we evaluate vocabulary, syntaxes and grammar which are relatively intact, although the sentence length tend to be reduced; the visuospatial disorders are frequent in PD; thinking and reasoning must also be examined, in both of them there is normal performance and they show a realistic appreciation of their condition and limitations; the executive functions are evaluated, there are consistent failures in tests that require concept formation and thinking flexibility. PD treatment can be medical using L-Dopa, or surgery through techniques by lesion or stimulation to different surgical targets like the internal globus pallidus, the subthalamic nucleus, or the ventral medial thalamic nucleus, unilateral or bilaterally. The PD repercussions in working memory (WM) will be studied related to executive functions, speech, cronometraje, saccades and attention.
