Preventing Falls

A fall is an unintentional loss of balance causing one to make unexpected contact with the ground or floor (Rammel, 1996).

Though this definition may sound simple, the issues surrounding falls are more complex. Falls among older persons are an important cause of injury, disability, and death. Falls are also an important indicator of decline in functional ability. Reducing fall risk requires careful assessment of the person who has fallen, as well as his or her surrounding environment.

Once the risks are identified, actions must be taken to reduce the risks (Hindmarsh, 1989).

Although falls happen at any age, this issue of HealthHints will focus on reducing risks for older adults since they run the greatest risk for decreased quality of life, and death due to injury from falls. Common risks will be identified, followed by suggested interventions.

The older adult population (persons 65 years or older) numbered 34.5 million in 1999. That's 12.7% of the U.S. population. Two million of these individuals reside in Texas. That's 10.1% of the Texas population. (Administration on Aging, 2001; Fedstats, 2001)

How Serious is the Problem of Falling?

According to the Centers for Disease Control and Prevention, in the United States:

In addition to the physical and emotional trauma caused by falls, in 1994 (the most recent data available), falls among people age 65 and older cost an estimated $20.2 billion (McGarry, 1999; Stevens, 2000); this number is expected to reach $32.4 billion by 2020. These figures do not include the indirect human and monetary costs of disability, lost productivity, and diminished quality of care (McGarry, 1999).

Risk Factors

Factors contributing to older adults' falls are internal and environmental. Some of these factors include:

History of a Previous Fall

An important question to ask when assessing someone's fall risk is about previous falls. People who have fallen previously are far more likely to fall again. Many people who fall do so repeatedly. Asking about previous falls is especially important when admitting an older person to either a nursing home or hospital so appropriate precautions are implemented. Older adults with a history of falling should also have a careful physical work-up to identify treatable problems.

Dizziness

Dizziness also raises an older adult's risk for falling. Dizziness may be due to a variety of causes such as medicines, heart arrhythmias, getting up too quickly, or inner ear problems. Whatever the cause, asking about feelings of dizziness is a very important part of assessing an older person's potential for falling. A thorough physical examination should be done to identify treatable causes for dizziness.

Drop Attacks

Drop attacks are sudden spontaneous falls while standing or walking, with complete recovery in seconds or minutes. There is usually no recognized loss of consciousness, and the event is remembered. A person with a history of drop attacks is at very high risk for falls and injury.

Drop attacks can have diverse causes including heart arrhythmias (syncope), seizures, or inner ear disease. In most cases, however, the cause of a drop attack is never identified.

Evaluation by a physician is important to identify a cause, if possible. Treating the identified cause of drop attacks is ideal. Since most causes remain unknown, however, assistance with walking and modifying the environment to remove hazards is all that can be done (Hain, 1999).

Balance and Gait

A combination of internal and external factors can create a loss of balance and gait (i.e., stride).

Muscle atrophy is one common reason for balance and gait problems. If we become less active in old age, our muscles atrophy, or get smaller and reduce our strength. This can reduce the mobility and balance we need to maneuver effectively and continue tasks of daily living, ultimately making us dependent on others.

One way to counteract muscle deterioration is through exercise, particularly a combination of aerobic, strength, and flexibility-type exercises. One example of exercise shown to improve balance among older adults is Tai Chi, a form of Eastern movement sequences. (For more on exercise see the box entitled "Important Types of Exercise" below.)

Since falls occur when balance and normal gait are disrupted, it can be beneficial to:

By making some simple lifestyle changes to promote safety, the likelihood of falling can be decreased. (Hinman 1996; Rammel 1996 ). See "Adapting the Home Environment" for more information.

Important Types of Exercise

Maintaining a regular exercise program can improve strength, balance and coordination. Making and maintaining these improvements requires three important types of exercise that can be done individually, as a single routine/program, or through daily tasks.

  1. Aerobic exercise (e.g., walking, swimming, cycling) -- exercises that maintain the heart and muscle function. These exercises can help one continue in activities of daily living, such as climbing a flight of stairs or walking through a grocery store pushing a cart without getting out of breath and/or requiring assistance.
  2. Strength exercise (e.g., weight training, resistive fitness bands, etc. ) -- exercise that uses your weight, free weights, or weight machines to cause resistance against your muscles, maintaining and building muscle strength (as well as increasing your metabolism). You need muscle strength to do simple tasks of daily living, such as rising from a chair or climbing a flight of stairs. Programs of strength training and physical therapy can produce increases in muscle strength in less than 2 months. These exercises can increase reaction time and decrease atrophy (Freedman 1996, Hinman 1996).
  3. Flexibility exercise (e.g., stretching, yoga) -- exercises that stretch your muscles and help you maintain or gain more flexibility. By maintaining flexibility one can continue necessary tasks, such as reaching a top shelf, or zipping the back of a dress.

It can be fun to join an exercise class or do your own routine at home or elsewhere. You might consider joining a local recreational facility, YMCA, or swimming pool. You can also check out exercise videos from a library, or rent or buy them at your local video or entertainment store. Still, if you find these ideas unappealing or too time-consuming, consider some of the following suggestions for incorporating physical activity into your daily life:

Remember: Always consult a physician before starting any exercise program. If you find any activity uncomfortable, or get out of breath, stop immediately! Your doctor can help you with an appropriate exercise or physical therapy program as needed.

Neurological and Musculoskeletal Disabilities

Certain neurological and musculoskeletal disabilities can put an individual at increased risk for falls. Some of the diseases influencing falls include:

Neurological Diseases

Multiple Sclerosis

Multiple sclerosis is a chronic, often disabling disease of the central nervous system. Symptoms may be mild such as numbness in the limbs or severe, including paralysis or loss of vision (National Multiple Sclerosis Society, 2001). Other symptoms that may put a person with multiple sclerosis at higher risk for falling include blurred or double vision, muscle weakness, impaired balance, spasticity, and tremors (National Multiple Sclerosis Society, 2001)

Parkinson's Disease

Parkinson's disease is a slowly progressive neurological disorder resulting from a loss of cells in areas of the brain that control movement, posture, balance, and walking. Some of the symptoms of Parkinson's disease that increase fall risk are:

Stroke

A stroke (also known as a "brain attack") occurs when blood circulation to the brain is interrupted or fails. A few minutes without oxygen and important nutrients from the blood to the brain can damage or kill affected brain cells. Though cell damage can sometimes be repaired, and some skills can be regained, the death of brain cells is permanent -- dead brain cells are not replaced. Thus, the devastating effects of stroke on the body are often permanent. If the cells affected are those responsible for mobility, balance, or gait, falls may result. (For more information on stroke, see HealthHints Vol. 4 No. 7.)

Musculoskeletal Diseases

Arthritis

Arthritis refers to over 100 different diseases that cause pain, swelling, and limited movement in and around the body's joints, thus, increasing risk for falls. Arthritis is one of the most prevalent chronic health problems and the number one cause of limitation in movement in the United States. Because arthritis limits movement, it often limits the ability to do tasks of daily living. Nearly 3 million Americans have arthritis that limits their ability to do such tasks as walking, dressing, or bathing. (For more information on arthritis, see HealthHints Vol. 1 No. 5.)

Osteoporosis

Osteoporosis is a disease that causes bones to become more porous, which gradually makes them weaker and more brittle. Healthy bone is dense and strong, able to withstand a great deal of pressure. When osteoporosis, literally meaning porous bone, sets in, bones thin and become fragile, making them more likely to break, and putting one at greater risk for falls. (For more information on osteoporosis, see HealthHints Vol. 4 No. 5.)

Medication Use

Medications may raise the probability of falling for a number of reasons. As we age, we may be affected by chronic disease, resulting in the use of multiple drugs. This multiple drug use can be a problem because the older adult body is less able to process and detoxify medications than it was at a younger age.

Taking multiple drugs also raises the possibility of harmful interactions, possibly leading to increased confusion, sedation, or dizziness. Additionally, reactions to drugs may be altered by the presence of more body fat and less muscle mass that are common as we age.

Medications may also stay in the body longer because of decreased kidney and liver function. As a result, a "normal dose," which produces no problems for a middle-aged person, may produce dizziness, drowsiness, unsteadiness, confusion, blurred vision, slowed reactions, and fatigue for an older adult.

Some categories of drugs also raise fall risk. For example:

Self-treatment may also produce problems leading to increased fall risk. To save money on prescriptions, individuals may be tempted to share medications. Herbals may also be used instead of, or in addition to, prescribed medications. Still others may choose to go to Mexico and purchase medicines for self-treatment.

To prevent falls related to medication use:

Confusion

If an individual suffers from confusion, he or she is more likely to fall. Falls result because the confused person is often:

Confusion can be brought on by many conditions including:

Visual Impairments

As we age, less light reaches the back of our eyes where vision is located. Acuity, or the ability to distinguish objects, also declines as we age, and as we reach age 90, our acuity may decline as much as 80%. This decline in acuity impairs the ability to perceive an object in contrast and spatial detail. Older persons may require three times more light for detection of objects in the environment.

Additionally, as we age our light-dark adaptation is slowed, there is more glare because of cataracts, and our accommodation to distance changes can decline.

What can be done to combat changes in vision and prevent falls?

Fear of Falling

A fear of falls contributes to the problem by causing inactivity and deconditioning, further increasing the danger of falls (Hindmarsh, 1989).

The fear of falling can create tremendous anxiety among the older adult population, particularly among those who have fallen before. This fear has been paralleled to the intensity of fear of missing an important appointment. Additionally, families often become overly protective and attempt to restrict their older relative's autonomy. In some cases, a family's reaction may lead to unnecessary institutionalization (Christenson, 1990; Howland, et. al., 1998).

The fear of falling is not restricted to those who have already had a fall, however. Others who have friends or relatives who have fallen may also exhibit an intense fear of falling.

The problem in both cases is not just the fear, but the reactions the fear causes. Fear of falling can cause one to be so cautious that he or she refuses to go out, or even go to the bathroom. When people move less based on fear, muscles begin to deteriorate more quickly, boredom and depression may set in, and the person becomes increasingly and prematurely dependent upon others, often leading to institutionalization (Christenson, 1990, Warren, 1996).

Fear can be useful when it causes us to exercise necessary caution, but a person can be cautious without letting fear dictate a lower level of activity and community involvement (Warren, 1996).

Here are some keys to reducing fear:

Note: As an educator to the public, it is important to create awareness about falls and not fear. Pay special attention to your words and illustrations when presenting a program on fall prevention. Place the emphasis on positive actions one can take to reduce the risk of falling.

Footwear

Wearing improper shoes or foot coverings such as socks or hosiery without shoes may cause a fall. When looking for proper footwear, consider the following tips:

(Fleck, 1995, Hinman, 1997)

Environmental Hazards

Environmental hazards, such as slippery surfaces, uneven floors, poor lighting, loose rugs, unstable furniture, improper bed height, and clutter, can lead to falls (Centers for Disease Control and Prevention, 1999). According to the Centers for Disease Control and Prevention, among individuals age 65 and older:

Though falls most commonly occur in and around the home, falls are also common when an older adult changes environments, particularly to a health care institution. This most likely results because surroundings are initially unfamiliar and/or these individuals are more frail than those living elsewhere.

Thus, to reduce the risk of falling, it is important to assess each individual and make appropriate adaptations in his or her environment.

Adapting the Home Environment to Reduce Fall Risk

Each room in the home can be adapted and modified to create a safer environment and reduce the potential for falls. Below are some general suggestions.

Bathroom

The bathroom is the room in the home where most falls take place. Problems occur due to difficulties getting in and out of the tub, on and off the toilet, difficulty seeing in dim lighting, slippery or wet surfaces, and dizziness standing at the sink. With minor modifications, the bathroom can become protected. Modifications include:

Bedroom

The bedroom should be thought of as a safe haven. With the following modifications, the bedroom can become a place of rest and relaxation:

Living Room

The living room is a place of entertainment and leisure, so safety is not a luxury, but a necessity. Modifications include:

Stairways

Stairways and even small steps up and down into rooms can be treacherous at all ages. To help improve safety, modifications may include:

Home Management Issues

In addition to room modifications, there are a few home management issues that need to be considered for modification:

Keep in mind, each individual and his or her environment should be assessed to meet individual needs.

Adaptation Issues for the Nursing Home Resident

An older person who is moving to a nursing home faces a totally new environment, in addition to increased physical and cognitive risk factors for falling.

Of the 1.5 million nursing home residents in this nation, approximately 50% fall at least once a year (Centers for Disease Control and Prevention, 1999). Some of the factors associated with this large percentage of falls are that nursing home residents tend to be:

Like the general older adult population, weakness and gait problems, problems with medications, and environmental hazards all increase the nursing home residents' risk for falling. Other causes of falls among nursing home residents include:

Thus, fall prevention among nursing home residents requires a combination of the following:

Note: Restraints and assistive devices can actually contribute to fall-related injuries and deaths. These restraints can actually limit freedom of movement and personal autonomy resulting in de-conditioning and muscle atrophy that can increase functional decline. For this reason, in 1990 a federal regulation took effect, reducing the use of physical restraints in nursing homes. In most nursing homes, fall-related injuries have decreased (Centers for Disease Control and Prevention, 1999).
