Resumen
In order to better understand the role of the vestibular system in postural adjustments on unstable surfaces, we analyzed the effects of galvanic vestibular stimulation (GVS) on the pattern of muscle activity and joint displacements (ankle knee and hip) of eight intellectually normal participants (control group - CG) and eight control group individuals with Down syndrome (DS) while balancing on seesaws of different heights. The CG individuals adopted a pattern of muscle activation characterized by alternation between ankle agonist and antagonist muscles. The individuals with DS adopted a pattern of muscle co-contraction. The GVS affected neither the ability of CG individuals to maintain balance nor their pattern of muscle contraction. On the other hand, the individuals with DS showed greater sensitivity to GVS while balancing on a seesaw and were not able to select the appropriate motor strategy to efficiently balance and compensate the effects of GVS. These increased vestibular sensitivities observed in individuals with DS can reflect deficits in the proprioceptive system. © 2011 Elsevier Ltd. 32 5 1542 1547 Almeida, G.L., Carvalho, R.L., Talis, V.L., Postural strategy to keep balance on the seesaw (2006) Gait and Posture, 23, pp. 17-21 Aruin, A.S., Almeida, G.L., A coactivation strategy in anticipatory postural adjustments in person with Down syndrome (1997) Motor Control, 1, pp. 178-191 Brandt, B.R., Rosen, I., Impaired peripheral somatosensory function in children with Down syndrome (1995) Neuropediatrics, 26, pp. 310-312 Carvalho, R.L., Almeida, G.L., Assessment of postural adjustments in persons with intellectual disability during balance on the seesaw (2009) Journal of Intellectual Disability Research, 53, pp. 389-395 Carvalho, R.L., Almeida, G.L., The effect of vibration on postural response of Down syndrome individuals on the seesaw (2009) Research Developmental Disabilities, 30, pp. 1124-1131 Cioni, M., Cocilovo, A., Di Pasquale, F., Rillo Araujo, M.B., Rodrigues Suqueira, C., Bianco, M., Strength deficit of knee extensor muscles of individuals with Down syndrome from childhood to adolescence (1994) American Journal on Mental Retardation, 99, pp. 166-174 Cole, K.J., Abbs, J.H., Turner, G.S., Deficits in the production of grip force in Down syndrome (1988) Developmental Medicine and Child Neurology, 30, pp. 752-758 Fitzpatrick, R.C., Day, B.L., Probing the human vestibular system with galvanic stimulation (2004) Journal of Applied Physiology, 96, pp. 2301-2316 Galli, M., Rigoldi, C., Mainardi, L., Tenore, N., Onorati, P., Albertini, G., Postural control in patients with Down syndrome (2007) Disability and Rehabilitation, 9, pp. 1-5 Gomes, M.M., Barela, J.A., Postural control in Down syndrome: The use of somatosensory and visual information to attenuate body sway (2007) Motor Control, 11, pp. 224-234 Haley, S.M., Postural reactions in infants with Down syndrome: Relationship to motor milestone development and age (1986) Physical Therapy, 66, pp. 17-22 Hlavacka, F., Horak, F.B., Somatosensory influence on postural response to galvanic vestibular stimulation (2006) Physiological Research, 55, pp. 121-127 Inglis, J.T., Shupert, C.L., Hlavacka, F., Horak, F.B., Effect of galvanic vestibular stimulation on human postural responses during support surface translations (1995) Journal of Neurophysiology, 73, pp. 896-901 Latash, M.L., Anson, J.G., What are normal movements in atypical populations?
