Home-based HIFST for Older Adults to Prevent Functional Decline

Status Completed

Clinical Trial Summary

After an injury, an older adult may experience changes to how they complete their daily activities and participate in physical activity. Changes in how or how often an older adult performs an activity (such as climbing the stairs) can be warning signs of increased future difficulties. The purpose of this study is to prevent this decline by providing an exercise program for older adults experiencing these changes. This pilot study will determine if a 12-week home-based high intensity functional strength training (HIFST) program is feasible for older adults who have had an injury from a slip, trip, or fall. HIFST involves combining periods of performing 'hard' everyday movements to build strength (for example standing and sitting from a chair) with periods of rest or 'easy' activity. Feasibility will be determined based on the amount of recommended exercise sessions people complete, the ability to enroll participants and have them finish the program, as well as demonstration of safety. The study will also measure the effects on physical functioning, cognitive functioning, and enjoyment. Interviews with participants in the HIFST program will be conducted after the 12-weeks to gather information on their experience, opinions, likes/dislikes, and suggestions. All this information will be used to guide a future larger study to determine effectiveness.

Clinical Trial Description

An injury from a slip, trip or fall in an older adult may instigate the onset of preclinical mobility limitation (PCML) which is a period of time in which modifications in task performance are indicative of an early stage of functional decline. Effective and enjoyable exercise interventions, which may be offered by home-based high-intensity functional strength training (HIFST), are needed during this period. More research is needed on the feasibility of conducting a home-based HIFST in a this group as well it's effects on physical functioning, cognitive functioning and enjoyment. This information, in conjunction with follow-up interviews to asses acceptability, will be used to inform plans of a future fully-powered trial to assess effectiveness. The primary objective of this trial is to determine the feasibility of 12 weeks of home-based HIFST for community-dwelling older adults who are post-injury as determined by adherence, recruitment, retention, and safety criteria. The secondary objectives are to determine preliminary evidence of effects on physical functioning, cognitive functioning (specifically executive functions and processing speed) and physical activity enjoyment. The investigators will also report any intervention-related adverse events (harms, such as muscle strains, sprains, etc.). The follow-up qualitative study will assess acceptability of the intervention including barriers/facilitators to participation and recommendations for changes. ;
