One of the most common reasons patients give for not exercising is an injury or pain. People often use knee or shoulder pain or some other limitation as an excuse for not playing sports or being physically active. And while certainly musculoskeletal injuries can affect participation, rarely should these injuries keep people on the sidelines permanently.

Joint pain is unfortunately a fairly common affliction among the United States population. According to the Centers for Disease Control and Prevention, in 2006 approximately 30% of adults reported that they experienced some sort of joint pain in the previous 30 days. Musculoskeletal injuries are rarely completely incapacitating, however. While many weekend warriors cite old knee or shoulder injuries as reasons that they can't exercise now, with so many options available, even people with real injuries should be able to modify their routines and still get in a good workout.

For example, a female with early knee arthritis can still perform cardiovascular-enhancing exercise. She might not be able to run long distances six or seven days a week, but she might be able to run two days a week and swim or ride a bicycle the other days to decrease the repetitive impact on her knees. A male with rotator cuff impingement from overuse at work or in the yard might have to back off from tennis or baseball, which might aggravate his shoulder, but he could play soccer or another non-throwing sport. And for athletes who enjoy lifting weights, simply adjusting a few of the exercises might be enough to exercise in spite of a current injury.

For those who fear that they are making an injury worse, they should see a sports medicine physician. Most injuries do not need surgery, and often there are simple initial treatments, such as physical therapy, home exercises, taping, or anti-inflammatory medications. And while patients are often reluctant to go to the doctor for fear of being completely shut down from a sport or activity, sports medicine physicians usually try to encourage treatments and rehabilitation that get people back to sports and exercise as quickly as possible.

Finally, even if the activity is potentially detrimental to a joint, it might not always be that bad. Someone with near bone-on-bone knee arthritis is possibly making his knee worse running every day. Having said that, if he wants to keep running, the benefits of his overall health might outweigh the risks to his knee. Daily exercise can provide multiple medical benefits, including improved cardiovascular function, lower blood pressure, and weight loss, as well as improved sleep and mood. Even if he needs a knee replacement in the future, the medical upside to exercise is significant.

While aches and pains can be an obstacle to physical activity, they shouldn't be permanent barriers to all exercise. If you are worried about injuries or exercise modification discuss it with a doctor and know that being physically active is possible despite these pains.

What kind of activities can we promote to keep people moving no matter the aches and pains?

"If you always put limits on everything you do, physical or anything else, it will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them." - Bruce Lee

As important as it is for health and fitness professionals to know what limitations an individual may have in terms of creating appropriate activities, especially for safety and medical considerations, it's also important to consider what that individual CAN do, and what they can do in context with their environment. The social model of disability has taught us that systemic barriers, negative attitudes and exclusion by society (whether purposely or not) are the main contributing factors in disabling people, not the disability itself.

The International Classification of Functioning, Disability, and Health, or ICF, is a comprehensive framework used by the World Health Organization (WHO) for describing and measuring health and disability at both the individual and population levels. This framework is used to assess the relationship among an individual's function, activities, and participation while also considering these in the context of the environmental and personal factors that influence an individual's overall health. 

The ICF puts the idea of 'health' and 'disability' in a new light and recognizes that any person can experience peaks and valleys in health, and therefore any person is prone to experiencing some kind of disability. It shifts the focus from what caused a disability to the impact that it has on the person. In addition, ICF considers the social aspects of disability and does not see disability as a medical condition. By including these contextual factors, the ICF helps us to assess the impact of the environment on the person's functioning, and therefore possibly assess potential "limitations" a bit differently.

The health domain and health-related domain contained in the ICF are described fromt he perspective of the body, the individual, and society in two basic categories: (1) Body Functions and Structures (system level); and (2) Activities and Participation (person level and person-environment interaction). The ICF can be used as a tool in exercise physiology to conduct a needs assessment or as an outcome evaluation. It allows the fitness professional to identify the barriers and facilitators that affect the health of the client with the disability and then find or create modifications for the specific individual in order to facilitate participation in an activity. The ICF emphasizes function, NOT the health condition, and categorizes the situation, NOT the person. Here is an example.

Do you see the ICF as having application in your field?

With the recent activities of the American Public Health Association's "Safety is No Accident: Live Injury-free" campaign during the week of April 4-10, we would like to continue to raise awareness about falls prevention. Falls are a major health concern among older adults. More than one-third of older adults fall each year, and fall rates increase with advancing age.¹ Falls are the leading cause of injury deaths, the most common cause of non-fatal injuries, and the most common reason for hospital admission due to trauma in older adults.² Every hour, there is one death and 183 emergency department visits for falls-related injuries among older adults and more than 95% of hip fractures are caused by falls.³

These facts are a scary reality; however, we know the most common risk factors⁴ of falling. They include the following:

• Conditions associated with aging
• Muscle weakness
• Difficulty with balance or walking
• Vision problems
• Pre-existing medical conditions that limit mobility, such as Parkinson's disease, stroke or diabetes
• Conditions that cause confusion
• Being on more than four medications at the same time
• Use of assistive walking device
• Environmental hazards (e.g. throw rugs or pets)
• Difficulty completing daily living activities
• Low blood pressure
• Fear of falling
• History of fears

We also know that maintaining physical activity is critical in helping to prevent falls and can have a significant impact on many of the risk factors listed above. Performing physical activities of any fitness level - including programs, Tai Chi, aerobics and yoga - can help improve balance, strength and flexibility, and get patients moving again. In fact, effective interventions to prevent falls in community-dwelling older adults included exercise-based interventions provided in the home or group setting.⁵ Exercise interventions that appear to have the greatest impact are balance activities performed in standing (limit upper-extremity support), and exercise programs that are progressed based on the individual person. General exercise programs on the other hand, which do not focus specifically on balance and strength, are not as effective as individually tailored exercise.⁶ Finally, there has been strong evidence that supports a multifactorial approach to preventing falls with programs that include not just exercise but also appropriate screening, gait training and environmental assessments.⁷

According to the American Geriatrics Society's (AGS) Clinical Practice Guidelines, all should be screened for risk of falling. The AGS recommends a brief screening tool that includes three questions:

1) Have you ever fallen in the past year?

2) Has the patient had an acute fall?

3) Does the patient have difficulty with walking or balance?

If inviduals aged 65 years and older state that they have experienced two or more falls or has sustained an injury from a fall, they are considered to be at risk for falling. Likewise, if the person has difficulty with balance or walking, they may be at higher risk.

All professionals working with older adults should be aware of the risk for falls and the factors associated with a higher risk. With greater vigilance, we can prevent the injuries related to falls in older adults, as well as the related loss of function and participation in daily activities.

Are you screening older adults for falls? What community fall prevention programs are available for older adults in your community?
