Reeducação da sensibilidade da mão: desenvolvimento de um modelo de luva sensorial

Abstract

Objective: To develop a sensory glove model and test it in subjects with normal sensitivity in the upper limbs, who have been trained to replace hearing with touch. Methods: To make the equipment, a glove, mini-microphones, amplifier and headphones were used. Seven female subjects, with a mean age of 26.28 years (± 1.03) were selected to use the equipment and differentiate textures after training. The training took place over seven days, fifteen minutes a day, with the aim of identifying textures through sound, using the sensory glove. At the end all subjects answered a questionnaire. Results: All the subjects rated the use of the glove as "comfortable". Three subjects (42%) rated the aesthetic appearance of the equipment as "excellent", two subjects (28.57%) as "good", and two subjects (28.57%) as "regular." Six subjects (85.7%) identified the textures by sound alone, and one subject (14.3%) reported that he was aided by touch. Conclusion: It is feasible to manufacture a model of sensory glove using national technology that is readily accessible and relatively low cost, enabling the identification of textures through sound when the equipment is used by individuals trained to replace hearing with touch. Level of Evidence: Level II, prospective comparative study.

Cortical and functional responses to an early protocol of sensory re-education of the hand using audio–tactile interaction

“…TG patients underwent three-month early sensory re-education of the hand using the sensor glove model developed by Mendes et al 7 No home sensory re-education program was used with either group and the CG did not receive early sensory re-education of the hand during these three initial months.…”

“…3 Lundborg et al 6 developed a sensor glove model, called the sensor glove system, which aims to preserve the cortical map of the hand after peripheral nerve injury. Mendes et al 7 also developed a similar model of the sensor glove with the same principles, and tested it in healthy volunteers to compare an auditory stimuli training with promised cortical reported results. Both sensor glove models 6,7 can during the initial and early stage after nerve repair, when no return of sensibility has yet occurred in the affected area of the hand, give the possibility of hearing the sound generated by the stimulus that the hand should feel.…”

It provides an alternative input to the brain which needs to be interpreted and decoded by the somatosensory area representative of the hand.…”
