Study Name

Publication

European Journal of Integrative Medicine

Purpose

This study aimed to investigate possible effects of mechanical massage and mental training, used either separately or in combination during working hours.

Methods

Employees were randomly assigned to one of the following groups: i) Mechanical massage combined with mental training (n = 19), ii) Mechanical massage (n = 19), iii) Mental training (n = 19), iv) Pause (n = 19), v) Control (n = 17). The study lasted for eight weeks. Heart rate, blood pressure and fingertip temperature were measured at start, after four and after eight weeks. 

Results

Between-group analysis showed that heart rate differed significantly between the groups after 4 weeks (p = 0.020) and tended to differ after eight weeks (p = 0.072), with lowest levels displayed in the massage group and the control group.


Blood pressure and fingertip temperature did not differ between the groups. Within-group analysis showed that mechanical massage decreased heart rate (p = 0.038) and blood pressure (systolic p = 0.019, diastolic p = 0.026) and increased fingertip temperature (p = 0.035).


Mental training programs reduced heart rate (p = 0.036). Combining the two methods increased diastolic blood pressure (p = 0.028) and decreased fingertip temperature (p = 0.031). The control group had a significant decrease in systolic blood pressure during the first four weeks of the study (p = 0.038).

Conclusion

Receiving mechanical massage and listening to mental training programs, either separately or in combination, during working hours had some positive effects on the employees' heart rate, blood pressure and fingertip temperature. The effects were especially strong for employees who received mechanical massage only.

Purpose

In the present study, the authors evaluate the effectiveness of a mechanical massage chair in reducing stress for people with serious and persistent mental illness.

Methods

This preliminary investigation involves the use of massage therapy for 19 people with serious mental illness, using a standardized massage protocol. Stress levels were assessed using a 7-point Likert scale, administered before and after each treatment session.

Results

Self-reported stress was found to be significantly reduced, with participants reporting an average stress reduction of 1.48.

Conclusion

This preliminary investigation demonstrates that use of a mechanical massage chair can significantly reduce self-identified stress levels in persons with serious mental illness.

Clinical Journal of Oncology Nursing

Purpose

A pre-/post-test initiative was implemented to determine the effects of massage chair sessions on ambulatory cancer center nurses (RNs and advanced practice providers) based on their perceived stress, blood pressure (BP), and heart rate (HR).

Methods

A mechanical massage chair was available for 20-minute sessions in a secure room, and nurses self-recorded perceived stress using a visual analog scale, as well as BP and HR using a wrist cuff device. Descriptive statistics and paired t tests were used to assess nurse characteristics and differences before and after massage chair sessions.

Results

Nurses participated in 200 massage chair sessions during a six-month period. Significant reductions were noted in perceived stress, systolic and diastolic BP, and HR.  

Conclusion

These data indicate that providing a relaxing room with chair massage has favorable effects on nurses’ perceived stress, BP, and HR.

The Journal of Alternative and Complementary Medicine

Purpose

The objective of the present study was to test massage applied with an automated massage chair on the back muscles with regard to the effects on the tension of other muscles or on the neurovegetative tone, and to compare three different automated massage techniques.

Methods

Ten healthy volunteers participated in the study. The experiment consisted of an initial 5-minute period of relaxation without massage, and 5-minute periods of three different massage programs (roll-stretch massage, shiatsu massage, and beat massage). Subjects were randomized as to the presentation order.


The following physiologic data were collected: frontalis and gastrocnemius electromyogram (EMG) activity, skin conductance, and peripheral skin temperature. Judgments of valence and arousal were registered using the penciland- paper version of the five-point Self-Assessment Manikin.

Results

Roll-stretch and shiatsu massage were rated by participants as more pleasant than the relaxation period without massage or the beat massage. Whereas the four conditions were similar with regard to the mean frontal EMG values (reflecting primarily affective states), they differed regarding the gastrocnemius EMG (relating more to a general level of tension), roll-stretch massage, and shiatsu massage, resulting in less muscle tension than the control condition.


Shiatsu massage was associated with significantly lower skin conductance than the control condition, whereas beat massage increased it significantly. A significant increase of skin temperature was found during the roll-stretch massage compared to the no-massage condition. 

Conclusion

Automated roll-stretch massage and shiatsu massage applied on the back can rapidly induce measurable relaxation in distant muscles not directly massaged, and is accompanied by signs of neurovegetative calming. Back massage applied by an automated massage chair may be an efficient and inexpensive general relaxation approach, and is especially interesting for patients who dislike to be touched.

Japanese Journal of Complementary and Alternative Medicine

Purpose

In the present study, using established methods to evaluate fatigue, we investigated the effect of automated air massage chair on fatigue in healthy volunteers

Methods

Ten healthy subjects participated in a randomized two-way crossover trial. As fatigue-inducing desk work, subjects performed 8 sets of a 30-min Uchida-Kraepelin psychodiagnostic test and 30-min advanced trail making test (ATMT) during the test day. Subjects rested 15 min on the air massage chair or control chair 4 times: immediately before and at 4, 6 and 8 hours after the start of the workload.


We evaluated the subjective feeling of fatigue by visual analogue scale, work performance by ATMT, and analyzed underlying mechanisms by biochemical parameters in saliva and urine.

Results

Stimulation by air massage chair alleviated the subjective sensation of fatigue and suppressed the decline in work performance. Furthermore, increase in salivary amylase activity and decrease in urine homovanillic acid/creatinine ratio was suppressed.

Conclusion

Automated air massage chair attenuated fatigue induced by desk work, most likely by correcting the imbalance in the autonomic nervous system. The air massage chair is thus recommended for relieving fatigue induced by work and daily activities.

Medicine

Purpose

We aimed to compare the efficacy and cost-effectiveness of a massage chair with those of conventional physiotherapy for the treatment.

Methods

This was a randomized controlled trial with a two-group parallel design. Following randomization and allocation, 56 participants were enrolled to receive either physiotherapy (n = 25) or mechanical massage using the massage chair (n = 31). Pain severity was measured using a visual analog scale (VAS) and satisfaction assessed with the McGill Pain Questionnaire (MPQ).


Quality of life modification was analyzed using the Functional Rating Index (FRI). Cost-effectiveness was analyzed by comparing the sum of physiotherapy fees and monthly rental fees for chair massage. 

Results

Physiotherapy and massage chair were both effective for pain control as assessed with the VAS (P < .001), satisfaction as assessed by MPQ (P < .001) and life quality improvement as assessed by FRI (P < .001) in both groups. Both VAS and FRI scores were significantly higher for physiotherapy than for massage chair (P = .03 and P = .03, respectively).


There was no significant difference in MPQ between the two groups. Massage chair therapy was more cost-effective than physiotherapy, at only 60.17% of the physiotherapy cost (P < .001). 

Conclusion

The home massage chair system was cost-effective, but pain control and disability improved more with physiotherapy. However, our results showed that the massage chair is a promising treatment for pain control and quality of life modification, but efficacy is still superior in physiotherapy and the chair is not a replacement for physiotherapy.

International Journal of Neuroscience 

Purpose

The purpose of the present study was to investigate the effects of massage on alertness as measured by accuracy of performance on math computations.

Methods

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

Group by repeated measures and post hoc analyses revealed the following:


  1. 1
    frontal delta power increased for both groups, suggesting relaxation;
  2. 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. 3
    the massage group showed increased speed and accuracy on math computations while the control group did not change;
  4. 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. 5
    salivary Cortisol levels were lower following the massage but not the control sessions but only on the first day; and
  6. 6
    at the end of the 5 week period depression scores were lower for both groups but job stress scores were lower only for the massage group.

Purpose

The aim of this study was to evaluate effects of EEG patterns induced by three types:

  1. 1
    resting mode (control group)
  2. 2
    light massage mode
  3. 3
    strong massage mode in the electrical chair-massager for 15 minutes) in a sample of 16 healthy adults. 

Methods


Results

Changes in anxiety and stress were assessed, and electroencephalogram was recorded. Anxiety scores(STAI: State Anxiety Inventory, VAS: Visual Analog Scale) decreased in all groups. For anxiety scores, the strong massage group showed the greatest decrease in stress.


All groups also showed an increase in delta and theta activity, but only strong massage group showed a signigicant difference. All groups showed a decrease in alpha activity. Also, EEG changes in two groups except a control group showed a decrease in beta activity.

Complementary Therapies in Clinical Practice

Purpose

To verify whether the mechanical massage using massage chairs and binaural beats (brain massage) affect the mental fatigue recovery and cognitive enhancements.

Methods

25 healthy adults used massage chairs that could provide mechanical massage and binaural beats (brain massage) for 20 min. Mental fatigue and cognitive function were assessed before and after receiving brain massage using electroencephalogram (EEG) and 5 prolonged cognitive tests.

Results

When a person received a brain massage on the massage chair, the decrease in mental fatigue was statistically significant compared to taking a rest or receiving a mechanical massage only on the massage chair. In addition, sustained attention, verbal short-term and long-term memory and non-verbal long-term memory were statistically significantly increased after using brain massage.

Conclusion

Brain massage (mechanical massage and binaural beats) are effective in reducing mental fatigue and improving the cognitive function.

Korean Journal of Acupuncture

Purpose

The purpose of this study is to investigate the effect of acupoint and meridian muscle massage given by automatic massage chair.

Methods

We recruited 30 patients with back pain who met inclusion criteria. Two weeks were given as a waiting period, and the massage intervention was applied 12 times for 4 weeks. The programmed automatic massage chair was used to provide effective stimulus on acupoints and meridians for 20 minutes.


We used Visual analog scale(VAS) and Korean Oswestry Disability Index(KODI) to quantify pain and function. We also recorded patients` all of vital signs and abnormal reactions during the trial to asses to assess safety.

Results

Two participants dropped out due to personal reasons and 28 participants completed the clinical trial. We found that the degree of back pain (VAS, KODI) decreased significantly after the trial. As a result, VAS score decreased from 6.44±0.85(Visit 2) to 4.59±1.52 (Visit 14)(p<0.001), and KODI score was also reduced from 14.79±5.13(Visit 14) to 9.04±4.52 (Visit 2) (p<0.001). Also, we did not find any adverse effects in this study.

Conclusion

We found that the acupoint and meridian muscle massage can effectively decrease back pain. This proves that the massage program designed by Korean medicine can be a good option to patients with back pain. However, further study with controlled design is still needed to verify its effectiveness.

Purpose

To investigate the effect of electrical automatic massage (EAM) at bedtime on sleep quality and fatigue.

Methods

massage chair (REX-L ® ) under the calm and dim light condition immediately before polysomnography. Participants reported perceived sleep latency, sleep duration, and fatigue using visual analogue scale following morning."}">We recruited consecutively 35 adults (23 male, 48.7±8.07 y) who complained of poor sleep (Pittsburgh Sleep Quality Index≥5) and fatigue (Chalder Fatigue Scale≥4). This is a cross over study including two consecutive sleep studies with or without EAM. The EAM session includes preset'sleep mode', which last 30 minutes covering whole body.


Participants were seated in the commercially available massage chair (REX-L ® ) under the calm and dim light condition immediately before polysomnography. Participants reported perceived sleep latency, sleep duration, and fatigue using visual analogue scale following morning.

Results

Polysomnography parameters and subjective reports were compared between sleep with EAM and sleep without EAM. Paired comparison on average revealed sleep structure improvement N1 (13.6→10.9%) and N2 sleep (59.3→57.2%) decreased, and N3 sleep increased (3.0→6.4%), as well as sleep latency (10.3→5.6 min). 


Improvement in arousal index (17.1→13.0/h) and apnea-hypopnea index (9.1→7.0/h) were also seen following sleep after EAM. Sleep efficiency and total sleep time were not changed by EAM. Participants subjective reports also indicated better sleep on EAM; more lengthened sleep (306→330 minutes) and more relieved fatigue significantly after EAM.

Conclusion

This study demonstrated that muscle relaxation through EAM at bedtime may improve the sleep and alleviate fatigue. It suggests that EAM may be one of alternatives to promote sleep quality. Further studies in a clinical setting are warranted to support this finding.

Investigation of trapezius muscle effect using Ogawa Master Drive massage chair with electromyogram (EMG) sensor

Publication

Master's Thesis - University of Malaya

Purpose

This study evaluated the effects of OGAWA Master Drive massage chair on the trapezius muscle by using surface electromyogram (EMG) sensor

Methods

Ten subjects with no previous neck and shoulder pain or deformity were subjected to two modes of Sensei massage on OGAWA Master Drive massage chair; with heat and without heat respectively. Surface EMG recordings were taken for baseline, during Sensei massage mode without heat, post massage without heat, post Sensei massage with heat, and post massage with heat. The mean average value for EMG amplitudes were taken and compared.

Results

In eight out of ten subjects, the massage mode with heat yielded bigger EMG amplitude shift than that of without heat. The study also found that four out of ten subjects showed increased amplitude shift from baseline average EMG, reflecting muscle tension post massage session with heat. The study also found that six out of ten participants preferred having the massage with heat as compared to without heat.

Conclusion

Heat massage
