Biofeedback training has been shown to improve balance almost regardless of its pathological derivation. However, the mechanisms by which it improves balance are not understood. Due to the immediate and permanent nature of most balance disorders, balance data prior to onset of the disorder may not exist. Categorizing the nature of the benefits of biofeedback is problematic. Muscle fatigue impairs somatosensory input, as well as temporarily diminishes balance. The purpose of this investigation is to determine if mechanisms of sensory impairment may be attenuated through the use of biofeedback. Sixteen healthy males (mean age = 24.75 +/- 2.82 years, mean height = 179.84 +/- 6.55 cm, mean weight = 85.41 +/- 10.17 kg) participated. Six visual and fatigue conditions were performed by each subject. Three visual conditions eyes-open with biofeedback (BF), eyes-open without biofeedback (EO), and eyes-closed (EC) were performed under both non-fatigue and fatigued states. All uni-lateral balance tests were performed on the KAT balance system. Fatigue conditions entailed two successive Wingate tests. Balance tests were completed at three time points resting (T1), immediate post-fatigue (T2), and 10-minutes post-fatigue (T3). Balance measures included balance index (BI), fore/back ratio (F/B), and right/left ratio (R/L). MANOVA with repeated measures on time and condition noted a significant effect of condition (F = 16.135; P =.000), an effect of time (F = 2.334; P =.039), and effect of condition by time (F = 1.50; P =.047). One-way ANOVA displayed significant differences in BI data across T1, T2 and T3. Tukey HSD pairwise comparisons indicated significant differences in several of the balance indices. Although the current results do not provide a definitive mechanism by which visual biofeedback attenuates the influences of fatigue on balance, they do provide insight into the training and treatment of sensory impairments through existing perceptual motor development concepts. These data suggest that clinicians should continue to utilize accessory stimuli in the treatment of sensory impairments through capitalization of the operable sensory systems.
