Study Finds Massage Therapy Supports Senior Health

Contributed by Beth Barberree, RMT, BA; Jolie Haun, PhD EdS, LMT, April Neufeld, BS, LMP

Do you ever wonder who will help keep your body moving around safely as you get older? According to JoEllen Sefton and fellow researchers, massage therapists could be key players in maintaining health of older persons, particularly postural control. This month's Massage Therapy Foundation article outlines the findings of Sefton's study that explored the effects of therapeutic massage on balance, neurological and cardiovascular outcomes in older adults. The results of this study were published in the International Journal of Therapeutic Massage and Bodywork in 2012, and it is the second of a two-part study conducted collaboratively by researchers at Auburn University and Samford University in Alabama.

The risk of falling is a major health concern for older people. Falls in the elderly population impact personal health, affecting patients physically and psychologically and often result in significant healthcare and rehabilitation costs. Decreased mobility due to falls can lead to loss of vitality and increased morbidity.

Sefton and colleagues wanted to explore whether therapeutic massage could restore muscle balance and function, improve appropriate muscle activation, decrease spasms, correct postural imbalances or improve gait and movement confidence. They hypothesized that therapeutic massage would produce an immediate increase in instability, then improve postural stability and decrease cardiovascular measures over time, and improve long-term stability and cardiovascular functioning. Positive changes in these measures may improve confidence and allow for increased independence in older individuals.

Participants were excluded if they reported any chronic diseases or medications that would affect the study's physiological measures. Participants were then randomized to the therapeutic massage treatment group or relaxation control group. The treatment group received six weekly 60-minute full-body massages that followed a standardized protocol, but left some flexibility for the massage therapists to respond to individual patient needs. The relaxation control group rested quietly in the treatment room for 60 minutes.

A number of assessments were conducted on both the therapeutic massage and control groups to test the study hypotheses. Static and functional balance were tested with the participants on one and both feet, and with eyes open and closed. Neurologically, motor neuron pool excitability, activation and modulation at the soleus muscle were assessed. Heart rate and blood pressure were recorded as the cardiovascular measures.

Immediate Treatment Effects

Assessments of postural control and cardiovascular measures were completed before the treatment, and then immediately after, 20 minutes after and 60 minutes post-treatment. Nervous system measures were completed pre-treatment and then 60 minutes post-treatment. The purpose of these tests was to determine whether the therapeutic massage intervention produced increased instability for participants immediately after.

The results replicated the researchers' earlier findings showing that instability did not increase immediately after therapeutic massage. This implies that current cautionary measures implemented for our clients are likely sufficient and should be continued, although some sensitivity with clients who have special circumstances will always occur. Interestingly, the results did not support previous studies that showed therapeutic massage to decrease cardiovascular measures immediately following treatment.

Week Six Short Term Effects

To determine differences that occur during the 60 minutes after a therapeutic massage intervention, balance and cardiovascular measures were assessed immediately post-therapeutic massage to 60 minutes post-therapeutic massage. The results of the balance and postural control measures together suggest an increase in postural stability through the 60-minute period following therapeutic massage when compared to the control group.

Nervous system measures were taken pre- and 60 minutes post-therapeutic massage only. The results again echo the researchers' earlier work, finding that when compared to only one session of therapeutic massage, an additional six weeks of treatment did not produce better performance on the assessments for the nervous system. The researchers speculated this may be due to decreased fatigue that would occur during each therapeutic massage application.

Cardiovascular measures indicated a trend of decreased systolic and diastolic blood pressure from immediate to 60 minutes post-treatment in the treatment group compared to the control. No changes in heart rate were found, and studies thus far have reported conflicting results. This led the researchers to recommend additional research on the mechanisms affecting cardiovascular measures and blood flow.

Long Term Effects

So, what was found one week after the last therapeutic massage session? The long-term treatment effects were assessed by comparing the therapeutic massage and control groups on balance, nervous system and cardiovascular measures pre-treatment at week six with those obtained at the follow-up testing session at week seven. The researchers found some effects to be fairly robust.

Assessment of balance at week six indicated no significant differences between the treatment and control groups. However, by week seven, testing showed significant differences between the therapeutic massage and control groups. This indicates that the treatment group had an improved ability to maintain balance at week seven.

No long term nervous system differences were found between the treatment and control groups, but the authors note there may be some methodological considerations that could be addressed in future work. With respect to cardiovascular effects, although there were no significant differences at week six, there were lower systolic blood pressures in the treatment group by week seven. No differences in diastolic blood pressure were found. Heart rate was higher for the treatment group at week six, but then by week seven, no differences were found when compared to the control group.

The researchers made a couple of observations about the study design that may have impacted research outcomes. First, participants were all healthy older adults who could be considered "young old," rather than "old old." Second, results may differ in individuals experiencing conditions common with aging such as osteoarthritis, high blood pressure or diabetes. The researchers also identified some limitations that should be considered when interpreting the findings, specifically that the participants self-selected to join the study. To account for these potential confounding elements, the team recommended a larger study in the future to include a wider range of participants.

As massage therapists see more clients who are aging, it becomes increasingly important to know how to appropriately care for them, and manage the instability that may occur when they get up off the treatment table. Understanding the physiological changes in the client, both immediately and over time, can equip us with information needed to provide good home care instruction.

The results reported by Sefton and colleagues indicate that therapeutic massage could be a beneficial non-pharmaceutical option to improve blood pressure and postural stability in older adults, short and long-term. These findings have implications for practice and policy, from the treatment room to reimbursement. The true impact of research such as Sefton's will come from replication and dissemination of findings and continued efforts to use research evidence to inform practice guidelines and standards of care.
