This randomized controlled trial investigated the impact of a six-month sensorimotor training program on postural control in 86 older adults aged 55-80. The study found significant improvements in mediolateral sway and local dynamic stability under specific visual conditions, with Approximate Entropy and Lyapunov Exponent showing notable effects. The results highlight the potential of targeted exercise in enhancing balance in this population.
Key findings
- Significant improvement in mediolateral sway under eyes-open conditions (ApEn_ML_OE: F = 8.7, p = 0.004).
- Lyapunov Exponent showed significant effects in anteroposterior and mediolateral directions under eyes-closed conditions.
- No significant differences were observed for Detrended Fluctuation Analysis (DFA).
- Inter-individual variability was substantial across participants.
Why it matters
Understanding how targeted exercise can enhance postural control in older adults is crucial for developing effective fall prevention strategies. Improved balance can lead to better quality of life and reduced injury risk in this vulnerable population.
