Objective: To investigate the effects of proprioceptive feedback intervention (PFI) with the SENSERite system and circumferential ankle pressure on ankle proprioceptive acuity and balance performance. Design: Repeated measure with double-blinded assessments of outcomes at 3 points. Setting: A university laboratory. Participants: 40 community-dwelling older adults with either lower (diminished) entering proprioceptive acuity (LEPA) or higher entering proprioceptive acuity (HEPA). Intervention: The control group received PFI alone and used perceptual error feedback presented in the SENSERite system's screen in terms of knowledge of results to match a self-selected target position as accurately as possible. The experimental group received concurrent PFI and circumferential ankle pressure. Main Outcome Measures: Electromechanically measured absolute constant error, variable error, and equilibrium score. Results: LEPA participants in the experimental group demonstrated significantly reduced absolute constant error across time (P<.05). No statistical significances for variable error and equilibrium score were observed. Conclusions: LEPA participants enhanced proprioceptive accuracy more from a combination of PFI and circumferential ankle pressure than from PFI alone via a mechanism known as peripheral control. In contrast, HEPA participants did not show significant improvement across time and may have relied on central control mechanisms to maintain accuracy. Balance performance was essentially unaffected by either intervention, perhaps due to lack of practice specificity.
