Effects of Micro Vibration Therapy Nursing Care on Muscle Hardness and Skin Blood Flow: A Pre/Post Group Comparison Study

Purpose: The purpose of this study was to investigate the effects of Micro Vibrational therapy (MVT) on muscle stiffness and blood flow in the skin before and after Micro Vibrational therapy in healthy subjects in order to scientifically verify the effects of MVT. Methods: Micro Vibrational therapy is nurse care use in Japan. It was performed on the backs of 30 subjects (8 males and 22 females) in their 20 s to 50 s according to the eligibility criteria. The resting state before implementation was set as the baseline for the control group, and after 30 seconds of MVT was set as the intervention group. The effects of the MVT were statistically analyzed by these factors and subjective sensation by Visual Analog Scale. Results: The muscle hardness of the area where the MVT was applied for 30 seconds decreased to 29.54 (SD 5.04) after the application, compared to 30.45 (SD 5.05) before. A corresponding t-test showed a significant difference (p = 0.019). Skin blood flow increased from a median of 0.76 (variance 0.062) before to a median of 0.86 (variance 0.16) after the procedure. The Wilcoxon rank test showed a significant difference (p = 0.000). Circulatory response was confirmed by SBP, DBP, and HR. SBP of 108.6 mmHg (SD 14.8) before the study decreased to 105.7 mmHg (SD 15.0) after the study, and DBP of 65.6 mmHg (SD 11.1) before the study decreased to 62.7 mmHg (SD 11.8) after the study. HR decreased from 71.6 beats per minute (SD 10.3) before to 69.2 beats per minute (SD 11.7) after. There was a significant difference in all cardiovascular indices (p < 0.05). VAS (pain, stiffness, and fatigue) was significantly decreased after MVT (p < 0.05). Conclusion: Micro Vibrational therapy tended to decrease muscle hardness and increase skin blood flow even in the short time of 30 seconds. The results suggest that local vibration stimulation is not likely to cause a sudden increase in blood pressure or pulse rate fluctuation. These results suggest that hand vibration nursing care may be applicable to acute patients with unstable circulatory conditions.

Clinical efficacy of magnetic vibration magnetoelectric therapy in the treatment of chronic prostatitischronic pelvic pain syndrome

BACKGROUND The prominent symptoms of chronic pelvic pain syndrome(CPPS)are urogenital pain,lower urinary tract symptoms,psychological problems,and sexual dysfunction.Traditional pharmacological treatments have poor efficacy and more untoward reaction and complications.Magnetic vibration magnetoelectric therapy is a non-invasive form of physiotherapy.Nevertheless,its effectiveness in improving urinary discomfort and relieving pain in patients requires further exploration.AIM To investigate the clinical efficacy of the magnetic vibration magnetoelectric therapy instrument in the treatment of chronic prostatitis(CP)/CPPS.METHODS Seventy patients with CP/CPPS were collected from the outpatient clinic and ward of the Department of Male Medicine,Jiangsu Province Hospital of Traditional Chinese Medicine,and were treated with magnetic vibration magnetoelectric therapy once a day for a period of 14 d.National Institutes of healthchronic prostatitis symptom index(NIH-CPSI),international index of erectile function 5(IIEF-5),premature ejaculation diagnostic tool(PEDT),generalized anxiety disorder(GAD),patient health questionnaire,the pain catastrophizing scale(PCS)and traditional Chinese medicine syndrome(TCMS)scores were performed before and after treatment.RESULTS The total effective rate of treatment was 58.5%,and the total NIH-CPSI score,pain symptoms,voiding symptoms,quality of life,IIEF-5,PEDT,GAD,PCS and TCMS scores all decreased significantly(P<0.05).CONCLUSION Magnetic vibration magnetotherapy is effective in improving urinary discomfort,relieving pain,improving quality of life,improving sexual dysfunction and relieving negative emotions such as anxiety in patients with CP/CPPS.

Local vibration therapy promotes the recovery of nerve function in rats with sciatic nerve injury

Objective:It has been reported that local vibration therapy can benefit recovery after peripheral nerve injury,but the optimized parameters and effective mechanism were unclear.In the present study,we investigated the effect of local vibration therapy of different amplitudes on the recovery of nerve function in rats with sciatic nerve injury(SNI).Methods:Adult male Sprague-Dawley rats were subjected to SNI and then randomly divided into 5 groups:sham group,SNI group,SNI+A-1 mm group,SNI+A-2 mm group,and SNI+A-4 mm group(A refers to the amplitude;n=10 per group).Starting on the 7th day after model initiation,local vibration therapy was given for 21 consecutive days with a frequency of 10 Hz and an amplitude of 1,2 or 4 mm for 5 min.The sciatic function index(SFI)was assessed before surgery and on the 7th,14th,21st and 28th days after surgery.Tissues were harvested on the 28th day after surgery for morphological,immunofluorescence and Western blot analysis.Results:Compared with the SNI group,on the 28th day after surgery,the SFIs of the treatment groups were increased;the difference in the SNI+A-2 mm group was the most obvious(95%confidence interval[CI]:[5.86,27.09],P<0.001),and the cross-sectional areas of myocytes in all of the treatment groups were improved.The G-ratios in the SNI+A-1 mm group and SNI+A-2 mm group were reduced significantly(95%CI:[-0.12,-0.02],P=0.007;95%CI:[-0.15,-0.06],P<0.001).In addition,the expressions of S100 and nerve growth factor proteins in the treatment groups were increased;the phosphorylation expressions of ERK1/2 protein in the SNI+A-2 mm group and SNI+A-4 mm group were upregulated(95%CI:[0.03,0.96],P=0.038;95%CI:[0.01,0.94],P=0.047,respectively),and the phosphorylation expression of Akt in the SNI+A-1 mm group was upregulated(95%CI:[0.11,2.07],P=0.031).Conclusion:Local vibration therapy,especially with medium amplitude,was able to promote the recovery of nerve function in rats with SNI;this result was linked to the proliferation of Schwann cells and the activation of the ERK1/2 and Akt signaling pathways.

Design of a Biomedical Device to Reduce Anxiety Experienced by Patients Diagnosed with Parkinson’s Disease

Parkinson’s disease (PD) is a neurodegenerative disease that occurs due to loss of nerve cells that produce dopamine in the brain, affecting approximately 4 million people worldwide. PD patients often feel an increase in anxiety levels daily. While there are medications/exercises to help relieve anxiety, there are limited methods to reduce anxiety without the help of a caretaker. As a result, MEDIC Foundation, a non-profit organization in British Columbia, Canada, is designing an automated system that consists of a wristband and an application which uses vi-bration therapy to help reduce anxiety of PD patients. Literature reviews were conducted to document the project’s needs. Phase I of the project focused on de-veloping a prototype for the application and phase II on developing the wrist-band. The team developed prototypes of a wristband that automatically applies vibration near the median nerve as the heart rate variability (HRV) deviates away from the normal threshold of the user, and an application that displays real-time heart rate variability signals as well as provides for relaxation. The development of the prototype is still in early progress. By creating this automated system, we aim to provide a solution to senior PD patients to relieve anxiety independently. .

Non-invasive physical therapy as salvage measure for ischemic skin flap:A literature review

This review focuses on the available evidence regarding the molecular mechanisms and treatment potential of several non-surgical physical therapies for managing flap ischemia to propose a non-invasive,economical,and simple treatment to improve flap survival.A review of the literature was conducted on the topics of various non-invasive methods for the treatment of ischemic necrosis of the distal end of the flap between 1988 and 2019.A total of 52 published studies were reviewed on the applications of hyperbaric oxygen therapy,electrical stimulation therapy,heat stress pretreatment,phototherapy,and vibration therapy to manage skin flap necrosis.The underlying molecular mechanisms of these physical therapies on revitalizing the dying skin flaps were discussed and preliminary clinical uses of these therapies to salvage the necrotic skin flaps were pooled and summarized for clarifying the safety and feasibility of these methods.Various physical therapy regimens have been ushered to manage necrotic development in cutaneous flaps.With the refinement of these new technologies and enhancement of related basic science research on vascular revitalization,the prevention and treatment of flap ischemia will enter a new era.
