An innovative and cost effective lower extremity blood circulation enhancer

TL;DR: An innovative and cost effective lower extremity blood circulation enhancer works on the basic principle of whole body vibration and shows that human muscles behave like a spring complex and readily absorb vibration.
Abstract: An innovative and cost effective lower extremity blood circulation enhancer works on the basic principle of whole body vibration. A prototype is designed with the circuitry consisting of five motors connected in parallel. The prototype is designed in the form of a strapped stocking which is to be worn on the legs and the foot. The motors have been positioned in the prototype in such a way that the major muscles of the lower extremity will directly receive the vibration. The prototype is designed using cotton cloth due to the advantages the material offers. After successful testing of the prototype on ten subjects, signals were acquired from the posterior tibial artery of each of them. The output was obtained in the form of graphs using MATLAB. The prototype was designed successfully at a low price using readily available materials. The outcome showed that there was an increase in circulation of blood in the lower extremities. Further, we also observed that human muscles behave like a spring complex. They readily absorb vibration. This can also be seen from the results of the signal processing.

TL;DR: Evidence suggests that acute vibration exercise seems to elicit a specific warm-up effect, and that vibration training seems to improve muscle power, although the potential benefits over traditional forms of resistive exercise are still unclear.
Abstract: Whilst exposure to vibration is traditionally regarded as perilous, recent research has focussed on potential benefits. Here, the physical principles of forced oscillations are discussed in relation to vibration as an exercise modality. Acute physiological responses to isolated tendon and muscle vibration and to whole body vibration exercise are reviewed, as well as the training effects upon the musculature, bone mineral density and posture. Possible applications in sports and medicine are discussed. Evidence suggests that acute vibration exercise seems to elicit a specific warm-up effect, and that vibration training seems to improve muscle power, although the potential benefits over traditional forms of resistive exercise are still unclear. Vibration training also seems to improve balance in sub-populations prone to fall, such as frail elderly people. Moreover, literature suggests that vibration is beneficial to reduce chronic lower back pain and other types of pain. Other future indications are perceivable.

TL;DR: The study findings suggest that short duration vibration alone significantly increases SBF; doubling mean SBF for a minimum of 10 minutes following intervention in individuals with healthy microcirculation.
Abstract: Summary Background: Circulation plays a vital role in tissue healing. Increases in muscle fl exibility and strength, secretion of hormones important in the regeneration and repair process, blood fl ow, and strength of bone tissues has been attributed to whole body vibration (WBV) combined with exercise. The purpose of the study was to determine the effects of short-duration, high-intensity, isometric weight bearing exercise (vibration exercise [VE]) and vibration only on skin blood fl ow (SBF). Material/Methods: Forty-fi ve subjects 18–43 years of age were randomly divided into three groups: Group 1 – VE, Group 2 – exercise only, and Group 3 – vibration only. SBF was measured using a laser Doppler imager at three time intervals: 1) initial base line, 2) immediately following intervention, and 3) 10-minutes following intervention. Results: There was no signifi cant difference between the three groups’ SBF prior to intervention. Immediately following the intervention a difference among groups was found. Post hoc testing revealed that Group 3 subjects’ mean SBF was signifi cantly increased at both post-intervention time intervals. Conclusions: The study fi ndings suggest that short duration vibration alone signifi cantly increases SBF; doubling mean SBF for a minimum of 10 minutes following intervention. The emerging therapeutic modality of WBV as a passive intervention appears to increase SBF in individuals with healthy microcirculation.

TL;DR: This work aims to investigate and design a smart compression stocking using shape-memory polymer that allows externally controlling the pressure level in the wrapped position on the leg using external heat stimuli.
Abstract: Proper level of pressure or compression generated by medical stocking or hosiery is the key element for successful treatment or management of chronic venous disorders such as oedema, leg ulcers, etc. However achieving the recommended compression level and, more importantly, sustaining it using stockings has been a major challenge to the health practitioners supervising the treatment. This work aims to investigate and design a smart compression stocking using shape-memory polymer that allows externally controlling the pressure level in the wrapped position on the leg. Based on thermodynamical rubber theories, we first derived several criteria that have to be satisfied simultaneously in order to achieve the controlled pressure adjustment using external heat stimuli. We then presented a case where such a stocking is developed using a blend yarn consists of selected shape-memory polyurethane and nylon filaments. Extensive experimental work has also been conducted to demonstrate the feasibility and explore the influencing factors involved.

TL;DR: Vibration type appears to be the most important factor influencing both muscle oxygenation and peripheral blood flow, and whole-body vibration was shown to positively influence peripheralBlood flow.
Abstract: Context: The use and popularity of whole-body vibration (WBV) has increased in recent years, but there is a lack of consensus in the literature about the effectiveness of the treatment. Objective: To quantitatively examine the effects of WBV on muscle oxygenation and peripheral blood flow in healthy adults. Data Sources: We searched Web of Science and PubMed databases and reference lists from relevant articles using the key terms whole body vibration, whole-body vibration, WBV, blood flow, peripheral blood flow, oxygenation, muscle oxygenation, circulation, circulatory, near infrared spectroscopy, NIRS, and power Doppler. Key terms were searched using single word and combination searches. No date range was specified. Study Selection: Criteria for inclusion were (1) use of a commercially available WBV device, (2) a human research model, (3) a pre-WBV condition and at least 1 WBV experimental condition, and (4) reporting of unstandardized means and standard deviations of muscle oxygenation or peripheral blo...
