Clinical Trial Summary

Falls are the leading cause of injury-related deaths in older (≥ 65 y/) community dwelling heart failure (HF) patients. Fall risks are even greater for those with HF due to decreased exercise capacity, loss of skeletal muscle & medication side effects. Though resistance training (RT) is effective for improving skeletal muscle, it has only a modest effect on improving balance, which is comprised of peripheral sensory input central integration, & motor output. A multi-component intervention focusing on balance retraining & strengthening the muscles supporting static/dynamic balance & functional mobility is necessary.

This pilot study will evaluate the effect of a multi-component balance & RT intervention on physical function, balance, & falls in older (≥ 65 y/) community dwelling heart failure (HF) patients. The study will also explore perceptions related to outcomes & the intervention through focus groups, generate data on adherence and generate data on feasibility of conducting the BASIC Training intervention. The results of this study will be used to develop a targeted intervention to induce changes in elderly HF patients to prevent future falls; thus reducing costs, physical & emotional burdens related to falls; & effect a major difference in the quality of life.

The study will be once per week supervised group sessions & twice a week home sessions, and include 30 Second Sit-to-Stand, Modified Clinical Test of Sensory Interaction on Balance, Activity Specific Balance Confidence Scale, Timed Up & Go, Dynamic Gait Index.

Description:

Purpose: The purpose of this pilot study is to evaluate the effect of a multi-component balance and resistance training [RT] intervention on physical function, balance, and falls in older [≥ 65 y/o] community dwelling heart failure [HF] patients. The study aims: 1] Pilot test multi-component balance activities and RT intervention on primary outcomes. 2] Explore perceptions related to outcomes and the intervention through focus groups. 3] Generate pilot data on adherence. 4] Generate pilot data on feasibility of conducting the BASIC Training intervention.

Background/Significance: Falls are the leading cause of injury-related deaths in this age group. Fall risks are even greater for those with HF due to decreased exercise capacity, loss of skeletal muscle and medication side effects. Though RT is effective for improving skeletal muscle, it has only a modest effect on improving balance, which is comprised of peripheral sensory input central integration, and motor output. A multi-component intervention focusing on balance retraining and strengthening the muscles supporting static/dynamic balance and functional mobility is necessary.

Methods: Design - Randomized, two-group with wait list control, repeated measures experimental design. Sample/ Setting - 40-50 participants recruited from a medical center heart failure clinic; supervised group sessions conducted in the center's health and wellness center. Procedures - Participants will be randomized to the intervention group or the wait list control group. Focus groups pre/post intervention. The intervention will be administered in 1x per week supervised group sessions and 2x a week home sessions. Instruments - 30 Second Sit-to-Stand, Modified Clinical Test of Sensory Interaction on Balance, Activity Specific Balance Confidence Scale, Timed Up and Go, Dynamic Gait Index.

Analysis Plan: Aim 1- independent t-test to compare change scores from baseline to the end of the first 12 week period for the intervention group with the wait list control group. A second analysis will combine data from the delayed intervention period for the wait list control group with that from the first 12 week period for the intervention group to test change. Supplemental analysis, involving only data from intervention group, will test whether change is sustained at 24 weeks. Aim 2 - thematic analysis conducted with focus group data. Aim 3 - adherence assessed by group session attendance and home activities completed. Aim 4 - assess and report logistics of conducting the study.

Nursing Relevance/Implications: This pilot study will initiate the process of developing a targeted intervention to induce changes in elderly HF patients to prevent future falls; thus reducing costs, physical and emotional burdens related to falls; and effect a major difference in the quality of life for this population.

Intervention

Other:
• Balance Intervention
The multi-component balance intervention will be 1x per week in supervised group sessions and 2x a week sessions at home. Sessions will begin with a 5 minute warm up of major muscle groups using flexibility exercises and end with a cool down. Sessions will focus on improving static balance in the initial stages, then progress to dynamic balance.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pre/Post Scores on the 30 Second Sit to Stand Test Will be Used to Detect Any Changes in Leg Strength and Endurance That Occur During the 12 Week Group Exercise Sessions.		Baseline and 12 weeks
Primary	Dynamic Gait Index	8 increasingly challenging walking tasks (normal gait speed, changes in gait speed, walking with horizontal and vertical head movements, walking with pivot turn, walking over and around obstacles and stair climbing). A walkway path measured at 20 feet was used. A research assistance observed and scored all participants using a 0-3 scale, 0 = severe gait impairment, 1 = moderate gait impairment, 2 = mild/minimal impairment, 3 = normal gait, with a total possible scale range of 0 to 24 points. Scores = 19 points was used to classify falling risk (Shumway-Cook et al. 1997).	Baseline and 12 weeks
Secondary	Activity Balance Confidence Scale	Total range = 0-100% Higher values represent better outcome Total score is averaged = total%/16 responses	Baseline and 12 weeks
