Effectiveness of Multimodal Training Compared to a Uni-Modal Walking Intervention on Postural Control, Strength, Gait Speed and Flexibility in Community-Dwelling Older Adults.

Background

Multimodal training may induce positive effects in different physical domains. Compared to unimodal training, multimodal training allows similar effect sizes at lower overall training volumes. Studies are needed to investigate the potential value of multimodal training with systematic training, especially compared to other exercise-based interventions. This study aimed to compare the effects of a multimodal training with an outdoor walking program, on postural control, muscle strength, and flexibility in community-dwelling older adults.

Methods

This study is a pragmatic controlled clinical trial. We compared two real community exercise groups: a multimodal group (n = 53) and an outdoor, overground walking group (n = 45). Both groups participated in 32 sessions of training, twice a week, over 16 weeks. Participants were evaluated using the Mini-Balance Evaluation Systems Test (Mini-BESTest), Handgrip, 5-Times Sit-to-Stand Test, 3-meter Gait Speed Test, and Sit and Reach Test.

Results

There was an interaction effect between evaluation and group in the Mini- BESTest with difference between pre and post-intervention only in multimodal group. Regarding gait speed, there was an interaction effect between evaluation and group with difference between pre and post-intervention only in the walking group. In the Sit and Reach Test: there was interaction effect between evaluation and group with difference between pre and post-intervention only in the walking group.

Conclusion

The multimodal training improved postural control, while an outdoor walking program improved gait speed and flexibility. Both interventions improved muscle strength without between-group differences.
