Improvement of a massage chair (BEG-100) on height growth in children with average: Human subjects research.

BACKGROUND: Studies that examine the growth effects of massage at ages beyond infancy are rare. A recently developed massage chair (BEG-100) targets teenagers who want to increase their growth. The chair can stretch areas around the knee after fixating the knee and ankle areas. METHODS: This is a clinical study that included 38 children aged 11 years whose heights ranged from 145.0 to 155.0 cm. We aim to observe the potential of a 24-week massage for growth promotion. We will also evaluate the changes in height percentile, height, height standard deviation score, bone age, height standard deviation score for bone age, growth rate, predicted height estimated from bone age, seated height-to-standing height ratio, weight, and body mass index. To confirm safety, the associated adverse events will be investigated. OBJECTIVE: The aim of this study was to investigate the growth-promoting effect of BEG-100 in children with average height.

Clinical outcomes and cost-effectiveness of massage chair therapy versus basic physiotherapy in lower back pain patients: A randomized controlled trial.

INTRODUCTION: Low back pain is a chronic recurrent symptom, which can lower the patient's quality of life. With technological development of automated home massage systems, now offers a promising alternative to physiotherapy. However, thus far, the effectiveness of such methods has not been evaluated. 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). CONCLUSIONS: 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.

The effects on mental fatigue and the cognitive function of mechanical massage and binaural beats (brain massage) provided by massage chairs.

OBJECTIVE: 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.

The efficacy and safety of microvascular decompression for hemifacial spasm in elderly patients.

OBJECTIVE: The purpose of this study was to examine the efficacy and safety of microvascular decompression (MVD) for hemifacial spasm (HFS) in elderly patients. METHODS: Between 1997 and June 2008, 1,174 patients had undergone MVD for HFS at our institute. Among these, 53 patients were older than 65 years. We retrospectively reviewed and compared the complication and the cure rates of these patients with those of younger patients. RESULTS: There were 38 females and 15 males. The mean duration of symptoms of HFS of these patients was 94.6 months (range, 12-360 months), compared with 67.2 months (range, 3-360 months) in the younger group. The overall cure rate in elderly patients who underwent MVD for HFS during this period was 96.2%. Permanent cranial nerve dysfunctions, such as hearing loss and facial palsy, were seen in 2 patients (3.8%, 2/53) in the elderly group and 19 patients (1.7%, 19/1121) in the younger group. The difference in permanent cranial nerve dysfunction between the two groups was not statistically significant. There was no operative mortality in either group. CONCLUSION: Microvascular decompression is the most effective surgical modality available for the treatment of HFS. Results of this study indicate that such technique can be performed in the elderly without higher rates of morbidity or mortality. Any patient with HFS, whose general health is acceptable for undergoing general anesthesia, should be considered as a candidate for MVD.

Communicating hydrocephalus associated with surgery or radiosurgery for vestibular schwannoma.

The purpose of this cohort study was to determine the incidence of communicating hydrocephalus (HCP) associated with the treatment of vestibular schwannoma (VS). Between January 2002 and December 2007, a total of 291 patients diagnosed with VS underwent either surgical resection or gamma knife radiosurgery (GKS). By analyzing the clinical data and MRI scans, we retrospectively reviewed and compared the incidence of communicating HCP between the two treatment modalities. During their clinical course, 10 of 291 patients developed new communicating HCP (3.4%): nine of 90 patients who were treated using GKS (10%) developed communicating HCP post-procedure, while only one of 146 patients who underwent surgical resection alone (0.68%) developed subsequent communicating HCP (p=0.002). The median event-free survival from the initial treatment with GKS to the development of communicating HCP was 22 months (range: 7-55 months). Three patients who developed new communicating HCP in the GKS group required surgical intervention, including ventriculoperitoneal shunt or endoscopic third ventriculostomy. There was no significant correlation between sex or tumor size and the incidence of communicating HCP in the GKS group (p>0.05). We found a relatively high incidence of communicating HCP after treatment in patients with VS, particularly for those patients in the GKS group. Therefore, the risk of communicating HCP should be considered in the follow-up of patients who undergo GKS for treatment of VS.
