Reducing fall risk by improving balance control: development, evaluation and knowledge-translation of new approaches

Problem

Falling is a leading cause of serious injury, loss of independence, and nursing-home admission in older adults. Impaired balance control is a major contributing factor.

Methods

Results from our balance-control studies have been applied in the development of new and improved interventions and assessment tools. Initiatives to facilitate knowledge-translation of this work include setting up a new network of balance clinics, a research-user network and a research-user advisory board.

Results

Our findings support the efficacy of the developed balance-training methods, balance-enhancing footwear, neuro-prosthesis, walker design, handrail-cueing system, and handrail-design recommendations in improving specific aspects of balance control.

Impact on Knowledge Users

A new balance-assessment tool has been implemented in the first new balance clinic, a new balance-enhancing insole is available through pharmacies and other commercial outlets, and handrail design recommendations have been incorporated into 10 Canadian and American building codes. Work in progress is expected to have further impact.     

What does it mean to transform knowledge into action in falls prevention research? Perspectives from the Canadian Institutes of Health Research

Introduction

The concept of knowledge translation as defined by the Canadian Institutes for Health Research and the Knowledge to Action Cycle, described by Graham et al (Graham et al., 2006), are used to make a case for the importance of using a conceptual model to describe moving knowledge into action in the area of falls prevention.

Method

There is a large body of research in the area of falls prevention. It would seem that in many areas it is clear what is needed to prevent falls and further syntheses can determine where the evidence is sufficiently robust to warrant its implementation as well as where the gaps are that require further basic research.

Conclusion

The phases of the action cycle highlight seven areas that should be paid attention to in order to maximize chances of successful implementation.     

Nonfatal bathroom injuries among persons aged ≥15 years--United States, 2008

Problem

Information about where nonfatal unintentional injuries occur is limited, but bathrooms commonly are believed to be a hazardous location.

Methods

Data from a nationally representative sample of hospital emergency departments (ED) was used to quantify and characterize nonfatal unintentional bathroom injuries among people aged ≥ 15 years.

Results

In 2008, an estimated 234,094 nonfatal bathroom injuries were treated in EDs. Most injuries (81.1%) were caused by falls and 37.3% of injuries occurred when bathing, showering, or getting out of the tub or shower. Both injury and hospitalization rates increased with age.

Summary

These results suggest that bathrooms tend to be most hazardous for persons in the oldest age groups.

Impact on Industry

Bathroom injuries among all household members might be reduced by increasing awareness about potentially hazardous activities in the bathroom combined with simple environmental changes such as adding grab bars inside and outside the tub or shower.     

Seasonal variation in fall-related emergency department visits by location of fall – United States, 2015

Introduction: In the United States, fall-related emergency department (ED) visits among older adults (age 65 and older) have increased over the past decade. Studies document seasonal variation in fall injuries in other countries, while research in the United States is inconclusive. The objectives of this study were to examine seasonal variation in older adult fall-related ED visits and explore if seasonal variation differs by the location of the fall (indoors vs. outdoors), age group, and sex of the faller. Methods: Fall-related ED visit data from the National Electronic Injury Surveillance System-All Injury Program were analyzed by season of the ED visit, location of the fall, and demographics for adults aged 65 years and older. Results: Total fall-related ED visits were higher during winter compared with other seasons. This seasonal variation was found only for falls occurring outdoors. Among outdoor falls, the variation was found among males and adults aged 65 to 74 years. The percentages of visits for weather-related outdoor falls were also higher among males and the 65–74 year age group. Conclusions: In 2015, there was a seasonal variation in fall-related ED visits in the United States. Weather-related slips and trips in winter may partially account for the seasonal variation. Practical Implications: These results can inform healthcare providers about the importance of screening all older adults for fall risk and help to identify specific patients at increased risk during winter. They may encourage community-based organizations serving older adults to increase fall prevention messaging during winter.     

Ecology of player-to-player contact in boys' youth soccer play

INTRODUCTION: Youth soccer (football) injuries occur for a wide range of reasons, but the most frequent cause of injury is via player-to-player contact. This study was designed to study the ecology of collisions between players during youth soccer play. METHOD: Six teams of 11- and 12-year-old male players were followed over the course of a full season. Games were videotaped and reviewed to address three primary questions: how frequently do player-to-player collisions occur; when and where on the field do those collisions occur; and what is the rate of falls and injuries as a result of player-to-player contact. RESULTS: A total of 1,279 player-to-player collisions was observed, or an average of 65.59 collisions per game. Nearly half of the observed collisions resulted in one or both players falling to the ground, and about one-tenth resulted in the referee calling a foul, but very few of the collisions (less than 1%) resulted in an injury. Collisions occurred relatively consistently throughout the games, no matter what the score was. They occurred most frequently in the midfield area, when the ball was on or near the ground, and when players were attempting to retrieve a loose, uncontrolled ball. CONCLUSIONS: Results are discussed with respect to implications for injury prevention.
