Training- and Cost-effectiveness of an Internet-based Lifestyle-integrated Functional Exercise Program (iLiFE)

Not Applicable

• Conditions: Fall
• Interventions: Behavioral: upper limb exercise training; Behavioral: internet-based Lifestyle-integrated Functional Exercise (iLiFE)

• Registration Number: NCT05694494
• Lead Sponsor: Chinese University of Hong Kong

Brief Summary

Falls are the second leading cause of unintentional injury and death around the globe. About one in every three older adults falls each year worldwide. With the aging population, the cost of treating fall-related injuries is increasing exponentially. There is a pressing need for a cost-effective fall prevention program. Ample evidence has shown the substantial standalone effectiveness of well-designed physical exercises in preventing falls. However, continuous exercise adherence is required for a long-lasting fall prevention effect. Unfortunately, adherence to an exercise program was generally only 21%. Building up the habit of doing regular exercise is thus crucial in preventing falls. Lifestyle integrated Functional Exercise program (LiFE) has been shown to be able to reduce the fall rate by 31% and maintain 64% of the participants exercising at 12 months follow-up. This proposed randomized controlled trial aims at comparing the effectiveness of an internet-based LiFE in reducing subsequent falls and promoting exercise adherence in community-dwelling older adults.

Detailed Description

All subjects will then be randomly assigned to receive either an internet-based therapist-led LiFE program with a home environment safety assessment (iLiFE) or attention control intervention. Randomization into block groups of four in a 1:1 ratio (the iLiFE group or the attention control group) will be generated in a password-protected excel file by independent research personnel not involved in data collection or intervention after the baseline assessment. The randomization will be concealed by the independent personnel. Research assistants who are blinded to the group allocation will conduct all the subsequent monthly surveillance and assessments at baseline and follow-up sessions. All data will also be entered and checked by the blinded research assistants. All procedures concur with the Declaration of Helsinki (2013).

Arm && Interventions

Group	Intervention	Description
attention control	upper limb exercise training	upper limb exercise training
iLiFE	internet-based Lifestyle-integrated Functional Exercise (iLiFE)	receiving Lifestyle-integrated Functional Exercise training and home safety assessment

Primary Outcome Measures

Name	Time	Method
fall incidence as assessed by monthly telephone or internet follow-up	12 months

Secondary Outcome Measures

Name	Time	Method
balance as assessed by functional reach tests	4 months	will be done at the baseline- and re-assessments
mobility as assessed by the Ten Metre Walk Test	4 months	will be done at the baseline- and re-assessments
muscle mass as assessed by the Bioimpedance Analysis (BIA)	4 months	will be done at the baseline- and re-assessments
postural hypotension as assessed by the blood pressure in sitting and standing	4 months	will be done at the baseline- and re-assessments
physiological fall risk as assessed by the Physiological Profile Assessment (PPA)	4 months	will be done at the baseline- and re-assessments
Cognitive flexibility as assessed by Trail Making Test	4 months	will be done at the baseline- and re-assessments
balance confidence as assessed by the Short version of the Chinese version of the Activities-specific Balance Confidence Scale	12 months	will be done at the baseline assessment, re-assessment, and the last monthly telephone or internet follow-up. The participants will be asked to indicate their level of confidence in performing each activity on a 0-100 scale. A higher score indicates better balance confidence.
balance as assessed by the 4-stage stance	4 months	will be done at the baseline- and re-assessments
physical activity level as assessed by thigh-worn accelerometer (ActivPAL4 physical activity monitor, PAL Technologies Ltd., Glasgow, UK)	4 months	The participants will be required to wear the device for 7 consecutive days right after the baseline assessment and the re-assessment. Data about the duration of time spent in different activity types such as walking and sitting will be extracted and calculated on a daily basis.
exercise adherence as assessed by Section B of the Exercise Adherence Rating Scale	12 months	This will be done at the re-assessment and the last monthly telephone or internet follow-up. The total score ranges from 0 to 24. Higher total scores indicate better exercise adherence.
mobility as assessed by the Short Physical Performance Battery Test	4 months	will be done at the baseline- and re-assessments
health-related quality of life as assessed by EQ-5D-5L	12 months	will be done at the baseline and re-assessment and the last monthly telephone or internet follow-up
mobility as assessed by the Timed Up and Go Test	4 months	will be done at the baseline- and re-assessments
