Integrative Medicine in Elder Care: Mind-Body and Energy Medicine
Integrative medicine takes a whole-person approach to treating long-term health problems that are hard to treat with standard treatments and drugs. It adds complementary (alternative) therapies to your current treatment plan. The goal is to improve the overall health and well-being of older adults, with a focus on how they eat, sleep, and deal with stress.

What is Integrative Medicine?
The National Center for Complementary and Integrative Health (NCCIH) defines complementary medicine as non-mainstream practices used together with conventional medicine, and defines alternative medicine as treatments used instead of conventional medicine. Integrative medicine health brings together complementary and alternative medicine (CAM) with conventional medicine. NCCIH groups CAM practices into natural products (herbs, vitamins, supplements); mind-body practices (meditation, yoga, tai chi); and other (energy medicine, homeopathy, naturopathy).
A major criticism from the scientific community is the lack of controlled research on complementary therapies and practices. Integrative medicine overcomes this by combining treatments from conventional and complementary medicine for which there is some high-quality evidence of safety and effectiveness. This edition of Elder Care focuses on mind-body and energy therapies, both of which have shown evidence of benefit for older adults.
Do Older Adults Use CAM?
Studies show that between 30% and 58% of older adults use CAM, and CAM use is continuing to rise. A significant concern however, is that 58% of older adults who use CAM do not discuss these therapies with their health care providers, and only 35% of reported CAM use is recorded in patients’ medical records. Furthermore, many people using CAM assume that “natural” equals “benign,” but a number of CAM practices have significant interactions and contraindications with conventional medical treatments. It is essential that all vitamins, minerals, botanicals, and other CAM approaches be reported and recorded to assure patient safety.
Mind-body medicine uses a variety of techniques designed to enhance the mind’s capacity to affect bodily function and symptoms. Some mind-body techniques that were considered CAM in the past are today considered mainstream, such as patient support groups and cognitive-behavioral therapy. Furthermore, mind-body techniques are gaining in popularity. The National Health Interview Survey of 2017 showed that the use of meditation, a key mind-body approach, increased more than three-fold from 2012 to 2017. When used with standard medical practice, these therapies have few negative effects. Caution should be taken to assure that these are used as complementary approaches, rather than alternative to standard effective therapies.
Meditation has been employed successfully to enhance well-being in older populations. A review of 25 years of studies showed that meditation-relaxation is easily taught to older adults, and preliminary studies have shown meditation to have a positive effect on attention and memory, to increase telomerase activity in blood cells, and reduce the gray matter volume reduction seen with aging. Meditation also reduces anxiety, increases self-esteem, decreases agitated behavior, and increases relaxation, even in older adults with advanced dementia.
The National Institutes of Health recommends meditation and relaxation as one of the first interventions for treating hypertension. Mindfulness meditation taught to community dwelling elders with chronic back pain improved their acceptance of pain and their physical functioning. Further, meditation and stress reduction may confer lasting benefit: long-term follow-up (average of 7.6 years) of 202 persons age 55 and above who participated in studies involving transcendental meditation showed that all-cause mortality was decreased by 23%, cardiovascular mortality by 30%, and cancer mortality by 49% as compared with control subjects in the same studies. All studies demonstrated that older adults are fully capable of understanding, learning, and practicing various meditative techniques.
Energy medicine therapies involve the use of energy fields. They are of two general types.
One is bio-electromagnetic-based therapies which involve the unconventional use of electromagnetic fields, such as pulsed fields, magnets, or alternating-current or direct-current. Some of these are now considered mainstream treatments, such as transcutaneous electrical nerve stimulation (TENS) units for pain treatment.
The other is biofield therapies. These therapies are intended to affect energy fields that purportedly surround and penetrate the human body. Examples include tai chi (discussed below) qi gong, reiki, and therapeutic touch. While the existence of biofields is unproven, some of the therapies have been found to be useful. Again, these should be undertaken as complementary rather than alternative treatments.
Tai Chi has existed as a systematic exercise and martial art in China for more than 2000 years. It consists of slow, circular movements that require muscles to remain relaxed while making a sustained, even, and continuous effort. It can be considered both a body-based and energy-based practice, as it is professed to move chi, the life-energy.
A randomized controlled trial of tai chi in patients with idiopathic Parkinson’s disease showed consistently better postural control with tai chi as compared to resistance training or stretching. A Cochrane review found that tai chi is likely effective in preventing falls in older adults, with studies showing a decreased likelihood of falls at 6 months following a tai chi program. It is also more effective than brisk walking for improving balance, flexibility, and lower extremity strength. Further, it has been shown to increase physical functioning (as measured by the Short-Form 36); increase reported feelings of relaxation; increase energy, and decrease fatigue. Besides having a beneficial effect on balance and falls, tai chi has been found to acutely decrease sympathetic nervous system activity.
When used as complementary treatments, mind-body and energy therapies may confer benefit in older adults. As with all modalities, it is important to evaluate each patient individually for the feasibility of treatment tolerability and effectiveness.
