RESUMO

The pulmonary complications are responsible for the greater cause of morbidity and mortality of individuals with low cervical spinal cord injury (C5-C7). Many are the known technique that can contribute for a pulmonary function next to the normal one. Among them the functional electrical stimulation has been described in literature as capable to bring important benefits regarding the muscular training, including the respiratory. Objective: To evaluate the response to the technology of the functional electrical stimulation of the abdominal musculature in the studied sample, for its essential importance and influence in the process of the breath and stabilization of the abdominal wall in the in dyspnea, the respiratory muscular strength and in the functionality of patients with chronic low cervical spinal cord injury. Method: a double blind random clinical research: pilot study, with five tetraplegics male individuals with avarege ages of 29,5 years, was carried through. The volunteers were divided into two groups for the proposed protocol application: an experimental group that the stimulaton received from the chain of the electric stimulation and a group control that did not receive the stimulaton. The following parameters have been evaluated: inspiratory and expiratory muscular strength, functional independence measurement (FIM) and degree of perceived effort (Borg Scale), before and after the application of the protocol of functional electrical stimulation of the abdominal musculature. Results: in the proposed parameters, the main results were the following: 50% of improvement of the inspiratory muscular strength for the experimental group, while one of the members of the control group have presented an reduction of 15% of the muscular strength, 45% of increase of the expiratory muscular strength for the individuals fro the experiment group and no alteration of the strength of the expiratory muscles for the control group. Related to the dispnea, all the volunteers have mentioned improvement, for that have been represented by a decrease from 10 to 3 points on the Borg Scale for a control groups volunteer and a reduction from 6 to 3 points for n individual of the experiment group related to daily activities mentioned by each individual. In the functionality parameter the experiment group have presented improvement in categories as ability of dressing the upper body, acquisition related to the abdominal muscular strength, moving from a 6 to a 7 punctuation on the FIM, as the control group have presented improvement on the functionality on the daily activities unrelated to the muscular strength gains of this muscle, such as in the question bath. Conclusion: the abdominal musculature in patients with low cervical spinal injury in chronic phase have responded to the functional electrical stimulation increasing the strength exerted of this muscle, developing the functionality of this volunteers and diminishing the dyspnea. Beside all that the results have demonstrated that a functional electrical stimulation program may bring physical and also psychological benefits, as occurred with the control group in relation to the dyspnea and functionality. Therefore, the functional electrical stimulation will be able to contribute with the prevention of pulmonary complications and with the functional recovery of these individuals.
