摘要

Context: Stochastic resonance stimulation (SRS) administered at an optimal intensity could maximize the effects of treatment on balance. Objective: To determine if a customized optimal SRS intensity is better than a traditional SRS protocol (applying the same percentage sensory threshold intensity for all participants) for improving double- and single-legged balance in participants with or without functional ankle instability (FAI). Design: Case-control study with an embedded crossover design. Setting: Laboratory. Patients or Other Participants: Twelve healthy participants (6 men, 6 women; age = 22±2 years, height = 170±7 cm, mass = 64±10 kg) and 12 participants (6 men, 6 women; age = 23±3 years, height = 174±8 cm, mass = 69±10 kg) with FAI. Intervention(s): The SRS optimal intensity level was determined by finding the intensity from 4 experimental intensities at the percentage sensory threshold (25% [SRS25], 50% [SRS50], 75% [SRS 75], 90% [SRS90]) that produced the greatest improvement in resultant center-of-pressure velocity (R-COPV) over a control condition (SRS0) during double-legged balance. We examined double- and single-legged balance tests, comparing optimal SRS (SRSopt1) and SRS0 using a battery of center-of-pressure measures in the frontal and sagittal planes. Main Outcome Measure(s): Anterior-posterior (A-P) and medial-lateral (M-L) center-of-pressure velocity (COPV) and center-of-pressure excursion (COPE), R-COPV, and 95th percentile center-of-pressure area ellipse (COPA-95). Results: Data were organized into bins that represented optimal (SRS opt1), second (SRSopt2), third (SRSopt3), and fourth (SRSopt4) improvement over SRS0. The SRSopt1 enhanced RCOPV (P ≤ .05) over SRS0 and other SRS conditions (SRS0 = 0.94±0.32 cm/s, SRSopt1 = 0.80±0.19 cm/s, SRSopt2 = 0.88±0.24 cm/s, SRSopt3 = 0.94±0.25 cm/s, SRSopt4 = 1.00±0.28 cm/s). However, SRS did not improve R-COPV over SRS0 when data were categorized by sensory threshold. Furthermore, SRSopt1 improved double-legged balance over SRS0 from 11% to 25% in all participants for the center-of-pressure frontal- and sagittal-plane assessments (P ≤ .05). The SRSopt1 also improved single-legged balance over SRS0 from 10% to 17% in participants with FAI for the center-of-pressure frontal- and sagittal-plane assessments (P ≤ .05). The SRSopt1 did not improve single-legged balance in participants with stable ankles. Conclusions: The SRSopt1 improved double-legged balance and transfers to enhancing single-legged balance deficits associated with FAI.
