Dual-tasking for Individuals With Lower Limb Amputation: Exploring the Relationship to Falls and Instrumental Activities of Daily Living — DIAL  

Amputation Clinical Trial

Official title:
Dual-Tasking for Individuals With Lower Limb Amputation: Exploring the Relationship to Falls and Instrumental Activities of Daily Living

Clinical Trial Summary

Veterans with dysvascular lower limb amputation (LLA) have a high fall risk, which persists despite completion of conventional rehabilitation. The presence of fall risk could be a primary reason for the high disability and low quality of life outcomes in this Veteran population. A potential novel intervention for this population is to train performance of tasks that require both physical and cognitive attention (i.e., dual-tasking). Therefore, the purpose of this study is to explore relationships between dual-task performance and self-reported falls for Veterans with dysvascular LLA. Further, dual-tasking occurs during everyday life and this project will examine the association between dual-task performance and participation in activities of daily living (basic and instrumental). The results will form the foundation for development and future study of a novel dual-task training program for Veterans with dysvascular LLA.

Clinical Trial Description

Purpose: To explore the relationship between dual-task performance, self-reported falls, and activities of daily living for Veterans with lower limb amputation. Dual-task performance will be assessed using overground ambulation and serial subtraction. Dual-tasking will then be compared to single-task silent walking or seated serial subtraction to determine the category each participant falls into: gait-priority trade off, cognitive-priority trade off, mutual facilitation, or mutual interference. Self-reported falls with be assessed with questionnaires including recent falls (1 month, 1 year), number of falls, fall injuries, and near-falls. Activities of daily living will be assessed using the Modified Barthel Index, and Frenchay Activities Index. Other self-report descriptive questionnaires include: demographic information, the Functional Comorbidities Index, and the Falls Behavioral Scale for the Older Person. Other performance measures include: the Berg Balance Scale, and the SLUMS cognitive screen. Aim 1: Compare the proportion of participants experiencing mutual interference during dual-task walking between fall groups (Non-fall is 1 fall vs. Recurrent-fall is >1 fall). Aim 2: Identify the relationships dual-task effects have with self-reported participation in activities of daily living (basic and instrumental ADLs). Aim 3: Qualitatively explore the effects of dual-tasking on self-reported fall or near-fall dual-task scenarios. Veterans with dysvascular LLA (n 30) will participate in semi-structured interviews describing these scenarios, and dual-task awareness in fall prevention. ;
