“…Given the similarity of balance‐correcting strategies between VL subjects and controls described above, it would seem logical that a biofeedback system 23 that aimed simply to reduce sway would be effective for these two populations. Presumably proprioceptive loss subjects would require a feedback device that helped to change the strategy used to correct balance instability.…”

“…The aim of the current study was to compare the modes of control in healthy, VL, and PL subjects during quiet stance 33 to those underlying balance corrections to support‐surface perturbations 11–13,27 . Having established differences between these populations, our goal was to apply this knowledge to rehabilitation concepts using biofeedback of body sway 23,24 …”

Movement strategies controlling quiet stance and rapid balance corrections may have common characteristics. We investigated this assumption for lower leg proprioceptive loss (PL), peripheral vestibular loss (VL), and healthy controls. Our underlying hypothesis was that changes in movement-strategy modulation following sensory loss would improve with prosthetic biofeedback. Quiet stance was measured under different sensory conditions and compared to corrections induced by multidirection support-surface tilts. Response synergies were assessed using electromyography recordings from several muscles. Biofeedback of trunk sway during gait and stance tasks used lower trunk rotations to drive head-band-mounted vibro-tactile and auditory actuators. Strategies of quiet stance were different for roll and pitch, depending on sensory conditions. Simultaneously acting strategies were observed for low- and high-frequency sway. PL induced strategies different from those of VL and controls. VL strategies were identical to those of controls but with greater amplitudes. Tilt perturbation movement strategies were similar to high-frequency strategies of quiet stance--multisegmental. VL induced increased trunk pitch and roll responses with hypermetric trunk muscle responses and hypometric knee responses but unchanged synergies. Increasing PL up the legs caused changed synergies. Biofeedback reduced stance body sway in VL and elderly subjects. In conclusion, several movement strategies underlie quiet stance with high-frequency strategies being common to those of perturbed stance. PL changes both movement strategies and synergies, whereas VL only causes pathological changes to the modulation depth. Thus, VL is more easily rectified using trunk sway positional biofeedback.

In many acute or chronic vestibular diseases in old age, the risk of falling is increased. A fear of falling often develops together with further limitations to physical activity and subsequent physical and psychological consequences. Falls represent a substantial health-related risk factor. A regular balance, walking and muscle training is an effective prophylaxis. Components of the treatment of vestibular diseases in old age are counselling and encouragement (psychotherapy), treatment of the specific organic disease, specific vestibular rehabilitation and a symptomatic medication therapy. Vertigo in old age is a multifactorial process. The differential diagnosis of disorders of the equilibrium function in old age represents a challenge which can only be overcome by interdisciplinary cooperation.
