“…With these characteristics, MMG permitted to study the adaptations of neuromuscular activation strategies induced by several conditions, such as climbing [49] or resistance and aerobic training [55]. Also different physiological models, such as potentiation [56], muscle pain [57], hypoxia [58], hypothermia [59], muscle relaxation [60,61], while overimposing an electrical twitch stimulation during maximum voluntary contraction [62], or during spinal anaesthesia [63] could be also investigated.…”

Purpose The review aimed to provide a wider overview on the new application fields of MMG signal. A particular emphasis on measurements reliability and sensitivity was also given. Methods Five electronic databases were searched for eligible studies published between 2000 and 2014. Two authors assessed selected articles. Several domains (sensor types, participants' characteristics, experimental protocols, investigated muscle/s, measured parameters, and main results) were extracted for analysis. From a total of 1326 citations, 170 were selected for evaluation and 111 studies were identified. Results From the analysis of the literature it resulted that MMG signal (a) has a high level of reliability, especially for the parameters calculated during isometric contractions; (b) can be used to examine muscle mechanical activation and motor unit recruitment strategies under several types of exercise paradigms; (c) is influenced by the mechanical characteristics of cross-bridges and series elastic components, and may provide deeper insights into their behaviour under several physiological models; (d) could be a useful biomarker for triggering orthosis or multifunction access devices, and for the evaluation of patients presenting alterations in muscle function. Conclusions The MMG approach has been proficiently applied in several fields ascribable to both exercise physiology and clinical settings. This approach can provide deeper insights into muscle mechanical behaviour under several physiological models and for the evaluation of patients with altered muscle function.

“…In particular, several authors investigated the torque and MMG changes at the onset (Cè et al 2017(Cè et al , 2013c(Cè et al , 2013aCogliati et al 2020;Esposito et al 2011Esposito et al , 2016 or at the end of evoked activity (Longo et al 2016;Esposito et al 2011Esposito et al , 2016Cè et al 2013cCè et al , 2014aCè et al , 2013b. The MMG detection techniques used the accelerometers (Longo et al 2016;Esposito et al 2011Esposito et al , 2016Cè et al 2013bCè et al , 2017 or the laser distance sensor (Cogliati et al 2020;Orizio et al 2013;Yoshitake et al 2008). Here, the experimental design based on tetanic stimulation allowed, for the first time in humans, to describe the time relationship between the tension decrease and the muscle re-lengthening throughout the entire relaxation process.…”

Purpose During alternate movements across a joint, the changeover from one direction of rotation to the opposite may be influenced by the delay and rate of tension reduction and the compliance to re-lengthening of the previously active muscle group. Given the aging process may affect the above-mentioned factors, this work aimed to compare the dynamics of both the ankle torque decline and muscle re-lengthening, mirrored by mechanomyogram (MMG), in the tibialis anterior because of its important role in gait. Methods During the relaxation phase, after a supramaximal 35 Hz stimulation applied at the superficial motor point, in 20 young (Y) and 20 old (O) subjects, the torque (T) and MMG dynamics characteristics were measured. Results The T and MMG analysis provided: (I) the beginning of the decay after cessation of stimulation (T: 22.51 ± 5.92 ms [Y] and 51.35 ± 15.21 ms [O]; MMG: 27.38 ± 6.93 ms [Y] and 61.41 ± 18.42 ms [O]); (II) the maximum rate of reduction (T: − 110.4 ± 45.56 Nm/s [Y] and − 52.72 ± 32.12 Nm/s [O]; MMG: − 24.47 ± 10.95 mm/s [Y] and − 13.76 ± 6.54 mm/s [O]); (III) the muscle compliance, measuring the MMG reduction of every 10% reduction of torque (bin 20–10%: 15.69 ± 7.5[Y] and 10.8 ± 3.3 [O]; bin 10–0%: 22.12 ± 10.3 [Y] and 17.58 ± 5.6 [O]). Conclusion Muscle relaxation results are different in Y and O and can be monitored by a non-invasive method measuring physiological variables of torque and re-lengthening dynamics at the end of the electromechanical coupling previously induced by the neuromuscular stimulation.

“…Indeed, transcutaneous neuromuscular electrical stimulation (NMES) is a non-invasive technique that can be used to evoke well graded and controlled muscle action (Orizio, Gobbo, Diemont, & Solomonow, 2007;Orizio et al, 2013). In fact, according to Gobbo, Maffiuletti, Orizio, & Minetto (2014) the stimulation with variable amplitude of stimuli at the muscle motor point (i.e.…”

“…"the skin area above the muscle in which an electrical pulse applied transcutaneously evokes a muscle twitch with the least injected current"), allows to accurately control the level of motor units spatial recruitment. This method is often used to study muscle electromechanical features and performance (Gobbo et al, 2014;Gobbo, Gaffurini, Bissolotti, Esposito, & Orizio, 2011;Orizio et al, 2007Orizio et al, , 2013Botter et al, 2011). The NMES maximal stimulation amplitude activates all the motor neuron axons or intramuscular axonal branches at the chosen motor point and, when low stimulation rate is administered, a sequence of maximal single twitches (STmax) is detectable from force transducer applied to bone segment of the involved joint.…”
