The following research published at the Touch Institute at the University of Miami School of Medicine shows the positive effects of massage therapy for many conditions affecting your employees:

Job Stress:

Katz, J., Wowk, A., Culp, D., & Wakeling, H. (1999). Pain and tension are reduced among hospital nurses after on-site massage treatments: a pilot study. Journal of Perianesthesia Nursing, 14, 128-133.

METHOD: The aims of this pilot study were (1) to evaluate the feasibility of carrying out a series of eight 15-minute workplace-based massage treatments, and (2) to determine whether massage therapy reduced pain and stress experienced by nursing staff at a large teaching hospital. Twelve hospital staff (10 registered nurses and 2 nonmedical ward staff) working in a large tertiary care center volunteered to participate. Participants received up to eight, workplace-based, 15-minute Swedish massage treatments provided by registered massage therapists. Pain, tension, relaxation, and the Profile of Mood States were measured before and after each massage session. RESULTS: Pain intensity and tension levels were significantly lower after massage. In addition, relaxation levels and overall mood state improved significantly after treatments.

Field, T., Ironson, G., Scafidi, F., Nawrocki, T., Goncalves, A., Burman, I., Pickens, J., Fox, N., Schanberg, S., & Kuhn, C. (1996). Massage therapy reduces anxiety and enhances EEG pattern of alertness and math computations. International Journal of Neuroscience, 86, 197-205.

METHOD: Twenty-six adults were given a chair massage and 24 control group adults were asked to relax in the massage chair for 15 minutes, two times per week for five weeks. On the first and last days of the study they were monitored for EEG before, during and after the sessions. In addition, before and after the sessions they performed math computations, they completed POMS Depression and State Anxiety Scales and they provided a saliva sample for cortisol. At the beginning of the sessions they completed Life Events, Job Stress and Chronic POMS Depression Scales. RESULTS: Analyses revealed the following: 1) frontal delta power increased for both groups, suggesting relaxation; 2) the massage group showed decreased frontal alpha and beta power (suggesting enhanced alertness), while the control group showed increased alpha and beta power; 3) the massage group showed increased speed and accuracy on math computations while the control group did not change; 4) anxiety levels were lower following the massage but not the control sessions, although mood state was less depressed following both the massage and control sessions; 5) salivary cortisol levels were lower following the massage but not the control sessions but only on the first day; and 6) at the end of the 5 week period depression scores were lower for both groups but the job stress score was lower only for the massage group.

Anxiety:

Shulman, K.R. & Jones, G.E. (1996). The effectiveness of massage therapy intervention on reducing anxiety in the work place. Journal of Applied Behavioral Science, 32, 160-173.

METHOD: An on-site chair massage therapy program was provided to reduce anxiety levels of 18 employees in a downsizing organization. 15 control group Ss participated in break therapy. Subjects’ stress levels were measured with the State-Trait Anxiety Inventory, which was administered twice during pretest, post test, and delayed post test to achieve stable measures. RESULTS: Significant reductions in anxiety levels were found for the massage group.

Back Pain:

Hernandez-Reif, M., Field, T., Krasnegor, J., Theakston, H. & Burman, I. (2001). Chronic lower back pain is reduced and range of motion improved with massage therapy. International Journal of Neuroscience, 99, 1-15.

METHOD: A randomized between-groups design evaluated massage therapy versus relaxation for chronic low back pain. Treatment effects were evaluated for reducing pain, depression, anxiety and stress hormones, and sleeplessness and for improving trunk range of motion associated with chronic low back pain. RESULTS: By the end of the study, the massage therapy group, as compared to the relaxation group, reported experiencing less pain, depression, anxiety and improved sleep. They also showed improved trunk and pain flexion performance, and their serotonin and dopamine levels were higher.

High Blood Pressure:

Hernandez-Reif, M., Field, T., Krasnegor, J. & Theakston, H.(2000). High blood pressure and associated symptoms were reduced by massage therapy. Journal of Bodywork and Movement Therapies, 4, 31-38.

METHOD: Thirty adults with controlled hypertension (for at least the last six months) were randomly assigned to either a massage therapy group or a progressive relaxation group. Those in the massage group were given twice-weekly 30-minute massage sessions for five weeks. Participants in the progressive muscle relaxation group received instructions on completing self-administered, twice-weekly 30-minute exercises for five weeks. Researchers instructed subjects to only perform their session on assigned days to ensure compatibility with the massage group's schedule. Relaxation sessions began with participants breathing deeply for several minutes while in a supine position with the hands alongside the body. They then followed instructions to tighten and then relax different muscles, moving upward from the feet to the head. Muscle groups included were of the feet, calves, thighs, hands, arms, back and face. Pre- and post-treatment assessments included: a state anxiety inventory (STAI) to assess current emotions; a salivary sample to measure the levels of the stress hormone cortisol; systolic blood pressure and diastolic blood pressure measures; the Center for Epidemiological Studies Depression Scale (CES-D) questionnaire to rate depressive symptoms; Symptom Checklist-90-Revised (SCL-90-R) self-report symptom inventory of depression, anxiety and hostility; and urinary catecholamines (biologically active amines which affect the nervous and cardiovascular systems) and cortisol measurement. RESULTS: Results showed that while both groups had lower anxiety levels (STAI) and lower levels of depression (CES-D), only the massage therapy group showed decreases in sitting diastolic and systolic blood pressure; decreases in salivary and urinary cortisol stress-hormone levels; and lower scores for depression, anxiety and hostility.

Cardiovascular:

Delaney, J.P., Leong, K.S., Watkins, A., & Brodie, D. (2002). The short-term effects of myofascial trigger point massage therapy on cardiac autonomic tone in healthy subjects. Journal of Advanced Nursing, 37, 364-71.

METHOD: This study investigated the effects of myofascial trigger-point massage therapy to the head, neck and shoulder areas on cardiac autonomic tone. A 5-minute cardiac interbeat interval recording, systolic and diastolic blood pressure and subjective self-evaluations of muscle tension and emotional state were taken before and after intervention. RESULTS: Following myofascial trigger-point massage therapy there was a significant decrease in heart rate, systolic blood pressure and diastolic blood pressure. Analysis of heart rate variability revealed a significant increase in parasympathetic activity following myofascial trigger-point massage therapy. Additionally both muscle tension and emotional state showed significant improvement.

Headache:

Hernandez-Reif, M., Field, T., Dieter, J., Swerdlow. & Diego, M., (1998). Migraine Headaches are Reduced by Massage Therapy. International Journal of Neuroscience, 96, 1-11.

METHOD: Twenty-six adults with migraine headaches were randomly assigned to a massage therapy group, which received twice-weekly 30-minute massages for five consecutive weeks or a wait-list control group. RESULTS: The massage group reported fewer distress symptoms, less pain, more headache free days, fewer sleep disturbances and taking fewer analgesics. They also showed increased serotonin levels.

Quinn, C., Chandler, C., & Moraska, A. (2002). Massage therapy and frequency of chronic tension headaches. American Journal of Public Health, 92, 1657-1661.

METHOD: This study examined the effects of massage therapy on chronic, nonmigraine headache. Four chronic tension headache sufferers (aged 18-55 yrs) received structured massage therapy treatment directed toward the neck and shoulder muscles during a 4-wk period. RESULTS: Massage therapy reduced the number of weekly headaches. Headache frequency was significantly reduced within the initial week of massage treatment, and continued for the remainder of the study. A trend toward reduction in average duration of each headache event between the baseline period and the treatment period was also observed.

Hypertension:

Hernandez-Reif, M., Field, T., Krasnegor, J., Theakston, H., Hossain, Z., & Burman, I. (2000). High blood pressure and associated symptoms were reduced by massage therapy. Journal of Bodywork and Movement Therapies, 4, 31-38.

METHOD: High blood pressure is associated with elevated anxiety, stress and stress hormones, hostility, depression and catecholamines. Massage therapy and progressive muscle relaxation were evaluated as treatments for reducing blood pressure and associated symptoms. Adults who had been diagnosed as hypertensive received ten 30-minute massage sessions over five weeks or they were given progressive muscle relaxation instructions (control group). RESULTS: Sitting diastolic blood pressure decreased after the first and last massage therapy sessions and reclining diastolic blood pressure decreased from the first to the last day of the study. Although both groups reported less anxiety, only the massage therapy group reported less depression and hostility and showed decreased urinary and salivary hormone levels (cortisol). Massage therapy may be effective in reducing diastolic blood pressure and symptoms associated with hypertension.
