Efectos del entrenamiento con electroestimulación muscular en pacientes afectados de hemofilia A
ABSTRACT Surface electrical stimulation has been applied to the biceps brachii of fifteen male subjects affected by severe haemophilia A, while fifteen healthy subjects constituted the control group. The treatment consisted of a total of twenty-four sessions. Electrical stimulation was applied in both arms. The isometric strength (MCVI), the electromyographic (EMG) and mechanomyographic (MMG) activity and the diameter (CSA) of the biceps brachii were measured in both arms before and after the eight-week treatment period. At the end of the treatment, people affected by haemophilia showed significant increases of 15.85% (p<0.001) of the biceps brachii while any significant difference between the pretest and postest was found in the control group. After the eight weeks of work, the MVCI of the haemophilic patients showed a significant gain of 4.64% (p<0.05). The activation of the nervous system obtained a significant improvement of the biceps brachii of 37.63% (p<0.05) while no significant change could be found in the triceps brachii. No changes were detected in the mechanomyographic activity. These results show that the application of electrical stimulation in contributes to the gain and development of strength and trophism. The treatment is well adapted to the patients characteristics and does not represent a threat to health and can be used for therapeutic purposes for patients with joint limitations due to various pathologies.
