HIV can affect the Nervous System causing neurologic conditions like vestibular system impairments, thus affecting postural stability. The visual (Vi), vestibular (Ve) and somatosensory (Pro) inputs are essential components of sensory processing required to maintain postural stability. However there is very few literatures related to the contribution of the visual and somatosensory systems in maintaining postural stability in asymptomatic, high CD4 count and low to none viral load individuals. PURPOSE: Identify balance deficiencies and describe the sensory systems used to maintain postural stability in asymptomatic people with HIV. METHODS: Postural stability was measured in 20 asymptomatic persons with HIV (11 male, 9 female, aged 43 ± 8 years; CD4 mean = 607.45 ± 282.48; BMI mean = 27.5 ± 5.4). Static postural control was evaluated during eight sensory conditions that perturbed or stimulated the Vi, Pro and Ve systems. RESULTS: A paired-samples t-test was conducted to compare eyes open on firm surface condition (baseline) with eyes close, eyes open HUD and eyes closed HUD conditions on firm surface. Similarly, we also compared the eyes open on a foam (baseline) with eyes close, eyes open HUD and eyes closed HUD conditions on a foam surface. There was a significant difference for the eyes open (M=.76, SD=.51) compared to the EC (M=1.21, SD=.88) conditions; t(19)=3.6, p = .002, EO HUD (M=1.52, SD=.88) conditions; t(19)=5.7, p=.001 and EC HUD (M=1.56, SD=1.03) conditions; t(19)=4.1, p=.001. Furthermore, there was a significant difference for the eyes open on a foam (M=7.36, SD=3.9) compared to the EC BF(M=20.65, SD=10.76) conditions; t(19)=6.1, p = .000, EO HUD BF (M=10.6, SD=3.6) conditions; t(19)=3.5, p=.002 and EC HUD BF (M=44.3, SD=28.6) conditions; t(19)=5.9, p=.000. CONCLUSION: It appears that asymptomatic individuals with HIV exhibit early signs of postural control difficulties. Our results suggest that when one or more system is alter or cancelled, the remaining systems are not capable of maintaining a proper postural stability. Thus, postural control instability can be detected in asymptomatic HIV patients under appropriate challenging conditions, previous to the evident appearance of vestibular impairments and/or history of falls.
