“…In contrast to our results, Fratini et al (2009) suggested the sharp EMG spectral peaks observed during WBV to result from motion artifacts. This discrepancy can most likely be ascribed to methodological constraints in (Fratini et al 2009).…”

“…In some studies, these peaks have been interpreted as the result of motion artifacts (Abercromby et al 2007). These results were confirmed by other authors using dummy-like electrodes, i.e., electrodes placed on the patella (Fratini et al 2009). Possible mechanisms contributing to the generation of motion artifacts were previously suggested to be variations in the half-cell potential caused by ionic gel movement at the metal-electrolyte interface and the skin-electrode interface (Kahn 1965), skin potential variations caused by skin stretch (Tam and Webster 1977;Ödman and Oberg 1982;Ödman 1981;de Talhouet and Webster 1996), and movement of the recording cables (Huhta and Webster 1973;Simakov and Webster 2010).…”

A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : The effect of muscle activity on bone tissue is well documented. However, there is not enough data on effect of bone tissue on muscle activity. The aim of this study was to determine whether bone exposed to cyclic mechanical loading affects muscle electrical activity in healthy adult volunteers. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : Fifty-six volunteers were included in this study. Muscle electrical activity was measured on flexor carpi radialis (FCR) muscle at rest and maximal voluntary contraction (MVC) as EMGrms by surface EMG. Rest-EMGrms, MVC-EMGrms and Hreflex of the right FCR were measured before and during vibration. The right distal radius bone mineral content (BMC) and density were measured by DXA. R Re es su ul lt ts s: : Rest-EMGrms significantly increased during vibration in all cases. Regression analysis revealed that ultradistal (UD) radius BMC was an independent predictor for the change in the rest-EMGrms during vibration. This analysis also indicated that UD radius BMC explained only 54.0% of the variance in the rest-EMGrms during vibration. MVC-EMGrms significantly increased during vibration. Regression analysis revealed that UD radius BMC was an independent predictor for the change in the MVC-EMGrms during vibration. This analysis also indicated that UD radius BMC explained only 28.3% of the variance in the MVC-EMGrms during vibration. H-reflex was significantly suppressed or depressed during vibration in all cases. C Co on nc cl lu us si io on n: : The current study suggests that bone exposed to cyclic mechanical loading can affect muscle electrical activity, based on its BMC. K Ke ey y W Wo or rd ds s: : Bone and bones; muscle, skeletal; vibration Ö ÖZ ZE ET T A Am ma aç ç: : Kas aktivitesinin kemik dokusu üzerine etkisi iyi bilinmektedir. Fakat, kemik dokusunun kas aktivitesi üzerine etkisi hakkında yeterli bilgi yoktur. Bu çalışmanın amacı sağlıklı erişkin gönüllülerde, siklik mekanik yüklenmeye maruz kalan kemiğin, kas elektriksel aktivitesi üzerine etkisi olup olmadığını incelemek idi. G Ge er re eç ç v ve e Y Yö ön nt te em ml le er r: : Çalışmaya 56 gönüllü dahil edildi. Sağ fleksör karpi radialis (FKR) kasından istirahatte ve maksimal istemli kasılma (MIK) sırasında, yüzeyel EMG ile kas elektriksel aktivitesi EMGrms olarak ölçüldü. Sağ FKR kasında vibrasyondan önce ve vibrasyon sırasında istirahat-EMGrms, MIK-EMGrms ve H-refleksi kaydedildi. Sağ distal radius kemik mineral içeriği (KMI) ve yoğunluğu DXA ile ölçüldü. B Bu ul lg gu ul la ar r: : İstirahat-EMGrms vibrasyon sırasında tüm olgularda anlamlı olarak arttı. Regresyon analizi vibrasyon sırasında istirahat-EMGrms'de meydana gelen değişim için ultradistal (UD) radius KMI'nin bağımsız bir belirteç olduğunu gösterdi. Bu analiz aynı zamanda, UD radius KMI'nin, istirahat-EMGrms'de vibrasyon sırasında meydana gelen değişimin % 54'ünü açıkladığını göstermektedir. MIK-EMGrms vibrasyon sırasında anlamlı olarak arttı. Regresyon analizi, vibrasyon sırasında MIK-...

“…Myoelectrical activity measurements recorded via SEMG could be affected by motion artifacts (6,24,25). Such artifacts can be eliminated using appropriate series of notch filters and full-wave rectification without losing valuable information on the motor unit response to vibration in SEMG data (26).…”

Whole-body vibration (WBV), as a method of exercise training, is becoming increasingly popular in physical therapy, rehabilitation, and professional sports, and is increasingly used in beauty and wellness applications due to its beneficial effects on the neuromusculoskeletal system. These benefits include improved strength, power, flexibility, jump height, and balance (1-4).However, little is known about the physiological mechanisms underlying the effects of WBV on muscular performance, although the presence of reflex muscle activity during WBV has been shown (4, 5). Tonic vibration reflex (TVR) is the most commonly cited mechanism to explain the effects of WBV on muscular performance, although there is no conclusive evidence that tonic vibration reflex (TVR) occurs (4-6). Studies have reported that direct vibration applied to a muscle or tendon stimulates muscle spindles, thereby causing a TVR to occur. As highlighted by these studies, muscle spindle Background: Whole-body vibration (WBV) induces reflex muscle activity and leads to increased muscle strength. However, little is known about the physiological mechanisms underlying the effects of whole-body vibration on muscular performance. Tonic vibration reflex is the most commonly cited mechanism to explain the effects of whole-body vibration on muscular performance, although there is no conclusive evidence that tonic vibration reflex occurs. The bone myoregulation reflex is another neurological mechanism used to explain the effects of vibration on muscular performance. Bone myoregulation reflex is defined as a reflex mechanism in which osteocytes exposed to cyclic mechanical loading induce muscle activity. Aims: The aim of this study was to assess whether bone tissue affected vibration-induced reflex muscle activity and vibration-induced muscle strength gain. Study Design: A prospective, randomised, controlled, double-blind, parallel-group clinical trial. Methods: Thirty-four participants were randomised into two groups. High-magnitude whole-body vibration was applied in the exercise group, whereas low-magnitude whole-body vibration exercises were applied in the control group throughout 20 sessions. Hip bone mineral density, isokinetic muscle strength, and plasma sclerostin levels were measured. The surface electromyography data were processed to obtain the Root Mean Squares, which were normalised by maximal voluntarily contraction. Results: In the exercise group, muscle strength increased in the right and left knee flexors (23.9%, p=0.004 and 27.5%, p<0.0001, respectively). However, no significant change was observed in the knee extensor muscle strength. There was no significant change in the knee muscle strength in the control group. The vibration-induced corrected Root Mean Squares of the semitendinosus muscle was decreased by 2.8 times (p=0.005) in the exercise group, whereas there was no change in the control group. Sclerostin index was decreased by 15.2% (p=0.031) in the exercise group and increased by 20.8% (p=0.028) in the control group. A change in th...
