Development and Evaluation of a Home-Based Dual-Task Training Program to Improve Balance Performance for Older Adults

Not Applicable

Completed

• Conditions: Elderly; Aged

• Registration Number: NCT02280928
• Lead Sponsor: Chiang Mai University

Brief Summary

The purpose of this study is to (1) develop and test the effectiveness of home-based interventions on dual-task performance in older adults; and (2) determine the generalizability of the four trainings (i.e. single-task motor training, single-task cognitive training, dual-task motor-cognitive training, and dual-task cognitive-cognitive trainings) to novel tasks.

Detailed Description

Although, dual-task motor-cognitive training has proven to be more effective in improving dual-task balance performance than traditional single-task motor training, poor evidence of training-related transfer to a novel dual task has been shown. Additionally, another important impediment to the development of intervention to improve dual-task balance performance is that the previous studies have largely focused on training in a laboratory, or clinical setting, often with one-on-one supervision by a therapist or research assistant. Even though the home-based approach is more pragmatic, desirable, and encourages accessibility, no study has been done to examine the efficacy of home-based dual-task training.

Therefore, this study aims to address these gaps in the literature by conducting a home-based program designed to improve dual-task performance with a broader transfer-of-training effects in older adults. Participants will be randomly assigned to one of four groups (i.e. single-task motor training, single-task cognitive training, dual-task motor-cognitive training, and dual-task cognitive-cognitive trainings).

Inclusion Criteria

• Able to walk at least 10 meters without any assistive device
• Having greater than 16/23 for illiterate persons, greater than 20/30 for primary education level persons, and greater than 23/30 for secondary education level persons on the Mini-Mental State Examination-Thai 2002 (MMSE-Thai2002)

Primary Outcome Measures

Name	Time	Method
The Center of Mass velocity and Base of Support distance	At baseline and after 4-week training	The Center of Mass velocity and Base of Support distance is referred as the direction of the center of mass velocity in relation to base of support. It is used to measure the control of dynamic balance throughout gait under single-task and dual-task conditions in order to examine training effect.
Spatio-temporal gait parameters	At baseline and after 4-week training	Spatio-temporal gait parameters is measured throughout gait under single-task and dual-task conditions in order to examine training effect.
