As we age, balance becomes more of a challenge and falls become a
serious threat to our aging, fragile bodies. Falls are a leading cause
of mortality among older adults ages 65 and older. With population
models predicting steep increases in the 65 and older population, the
need to address these falls and the strain they place on the health care
system is vital. The implementation of mainstream fall-prevention
programs into senior communities could be an important first step.
Many studies have shown that the regular practice of
tai chi
significantly improves balance and is an effective means of preventing
falls in seniors. A study published in the July 2008 issue of the
American
Journal of Public Health, "Translation of an Effective
Tai Chi
Intervention Into a Community-Based Falls-Prevention Program,"
evaluated the success rate when offering a
tai chi program at
community-based centers.
Researchers evaluated the Tai
Chi - Moving for Better Balance program, an evidence-based
falls-prevention program specifically developed for use with community
centers. The 12-week study included the participation of 140 seniors (60
years or older) in six community centers for twice-weekly, one-hour
classes. The classes were taught by trained community tai chi
instructors between April 2006 and April 2007. Each class consisted of
five to 10 minutes of warm-up exercises, followed by the eight-form tai
chi program, ending with a five-minute cooldown. The participants
were also given a videotape or DVD and user's guidebook for practice at
home.
Using the RE-AIM model of evaluation, the researchers
primarily focused on the program's reach, adoption and implementation,
with the secondary focus being the program's effectiveness and
maintenance. RE-AIM elements (specific to this study) were:
- Reach - The number of eligible individuals who
qualified per the study criteria (physically mobile seniors w/o severe
mental deficits), divided by the total number of individuals who
responded to the program promotion, multiplied by 100.
- Adoption - The percentage of total local
community senior centers approached that agreed to participate and
implement the program.
- Implementation -
The extent to which providers and instructors successfully implemented
key elements of the program.
- Effectiveness
- The change in measures of physical performance and quality of life.
- Maintenance - The center's willingness to
consider tai chi as part of its program offerings and
continuation of the program after completion of the intervention.
Study findings revealed 89 percent participation by eligible seniors
(reach) and a 100 percent adoption rate. All participating centers and
instructors successfully implemented the program. The program had an
attendance rate of 80 percent and an average of 32 minutes of at-home
practice per participant each week. All participants also expressed
their intention to continue the program if it were offered in their
community.
At the end of the study, follow-up reviews determined
the program's effectiveness and maintenance. Using various measures,
researchers found significant improvement between pre-intervention and
post-intervention, including improvement in participants' reach and
50-foot speed walk. All of the centers reported their intention to
continue offering the program; five centers continued offering tai
chi classes, and one was waiting for the availability of an
instructor.
The researchers concluded that the evidence-based tai
chi program can be implemented and maintained in urban and rural
community settings. Of the senior participants, 92 percent continued tai
chi practice after the intervention ended. The researchers added
that although the implementation was successful, continued efforts are
needed to "address several translation, implementation and evaluation
issues" along with documentation of "whether this program can improve
health while reducing health care costs." Nevertheless, they feel the
program is practical to implement and maintain in community settings.
