Summary

Falls are the leading cause of accidental injury and injury-related death among older adults. Despite evidence that falls can be prevented, fall related injuries have not declined over time. Current fall injury prevention techniques targeting mobility and bone strength have merit yet their effectiveness is limited. Indeed, a recent Patient Centered Outcomes Research Institute/National Institute on Aging funded pragmatic trial of individualized multifactorial strategy to prevent serious fall injuries in over 5500 seniors revealed no difference in fall injuries between the intervention and standard care arm. The inconclusive results of the investigation may be due in part to focusing on fall prevention rather than mitigation of fall-related impact acceleration and forces - the "fundamental variables" for injury prevention. A fall-related injury occurs when the body hits the ground with force that is greater than tissue strength. Development of innovative approaches that focus on fundamental variables of injury prevention is needed.

Detailed description

Impact forces and body accelerations can be mitigated by performing specific movement patterns during the impact phase of a fall. The investigators, along with others have postulated and provided preliminary evidence that older adults can learn specific movement patterns (enacted during the impact phase of a fall), such as the tuck and roll that significantly reduce impact forces and minimize the risk of injury. The investigators' recent Randomized Clinical Trial (RCT) that examined the FAlling Safely Training (FAST) program in 17 older adults with low fall risk found that following 2 hours of training, the FAST group reduced their hip impact force by 33% and head acceleration by 59% and demonstrated retention. The procedures were feasible and safe in relatively healthy older adults with low fall risk. Despite the promise of this approach, perhaps the most important issue for real world translation is whether at-fall risk older adults with known balance impairment, a key target group who would most benefit from this training, can safely learn to fall with reduced impact forces and thus potentially fewer injuries using this paradigm. The immediate goal of this investigation is to determine the safety and feasibility of FAST training in an at-fall risk older adult group, the key measurable stages of FAST mastery, and, most importantly, the effect size, compared to modified Otago Exercise Program (an evidence-based fall risk reduction program) controls, to inform a larger future trial. To maximize safety, participants will utilize a protective helmet, and hip protector while landing on a cushioned pad. In addition, using a motor learning approach, the investigators will determine and measure key stages of the technique that can be mastered and measured as intermediate measures to document training progression.

Interventions

Type	Name	Description
OTHER	FAST Program	This program aims to teach how to effectively reduce impact forces during a sideways fall by 1) changing the trunk/knee angles during descent to decrease body acceleration, 2) using a rolling movement to allow for an optimal distribution of impact forces applied to any site along the contact path; and 3) tucking the chin to protect the head.
OTHER	Otago Exercise Program	The Otago Exercise Program (OEP) was chosen, rather than no control intervention, to increase the level of evidence required to demonstrate efficacy, and because, similar to the safe fall training used here, it was designed to be performed individually or in small groups.
