The Effects of Attention Focus Walking Training on Conscious Motor Processing During Rehabilitation by Older Adults at Risk of Falling (78834)
Session: On Demand
Room: Virtual Poster Presentation
Presentation Type: Virtual Poster Presentation
Conscious motor processing could impair movements by disrupting automatic movement control while external focus strategy has been proposed to potentially reduce real-time conscious motor processing in older adults during adaptive locomotion. This study aimed to examine the immediate impact of walking training with different attention focus instructions on real-time conscious motor processing in older adults at risk of falling. One hundred and two older adults (mean age: 75.2±6.8) were included in this primary outcome analysis. Participants were randomly assigned to the no attention focus walking group (NAFWG: n=34), external attention focus walking group (EAFWG: n=34), or internal attention focus walking group (IAFWG: n=34). All groups underwent 12 training sessions, including a 20-minute walking training along a 40-meter walkway at self-selected pace with distinct walking instructions. Assessments were conducted at baseline (T0) and immediately post-training (T1). Electroencephalography (EEG) T3-Fz coherence was used to indicate real-time conscious motor processing. Series of 3 (Group: NAFWG, EAFWG, IAFWG) x 2 (Time: T0, T1) ANOVA with repeated measures were conducted. We observed a significant Group x Time interaction effect on EEG T3-Fz coherence (F[2, 95] = 4.60, p = 0.01, ηp2 = 0.09). Post hoc comparisons revealed only EAFWG showed significant reduction in EEG T3-Fz coherence at T1 compared to T0 (t[32] = 2.58, p = 0.02). Our primary outcome analysis discovered a reduction on real-time conscious motor processing in older adults immediately after gait training with external focus instructions. Further analysis is needed to examine potential long-term impacts and their contribution to fall risks.
