“…Five studies focused on patients with spinal cord injuries [109][110][111][112][113], two on patients with Parkinson's disease [27,114] and with chronic obstructive pulmonary disease [115,116], one study on patients with myopathy [117]. The other six studies were conducted on healthy, able-body participants [20,28,30,[118][119][120].…”

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.

“…Kawakami et al [119] reported correlations between the needle EMG signal of the lateral pterygoid muscle and the MMG signal during different mandibular positions, suggesting that the activity of this muscle could be evaluated by MMG signal recorded in the external ear canal.…”

“…Another study [31] included muscle balance investigation of quadriceps muscles. Seven studies [7], [22], [33], [62]–[65] involved muscle activities of movements from different muscles, and the rest nine [8], [37]–[39], [44], [66]–[69] were related to investigation of MFs of diverse exercises from quadriceps muscles.…”

“…Researchers are exploring to set suitable methods to examine muscles' activities noninvasively; these methods for example, include surface electromyogram (sEMG) [1], [2], sonomyogram (SMG) [3], [4], tensiomyogram (TMG) [5], [6], and mechanomyogram (MMG) [7], [8].…”

“…The term mechanomyography represents a technique by which the mechanical activity of muscle is detected using specific transducers to record muscle surface oscillations due to mechanical activity of the motor units [12]. MMG signals can be detected using several types of transducers including piezoelectric contact sensors (PIZ) [13]–[15], microphones (MIC) [7], [16], [17], accelerometers (ACC) [18]–[22] and laser distance sensors (LDS) [23]–[25].…”

Mechanomyogram for Muscle Function Assessment: A Review

et al. 2013

View full text Add to dashboard Cite

BackgroundMechanomyography (MMG) has been extensively applied in clinical and experimental practice to examine muscle characteristics including muscle function (MF), prosthesis and/or switch control, signal processing, physiological exercise, and medical rehabilitation. Despite several existing MMG studies of MF, there has not yet been a review of these. This study aimed to determine the current status on the use of MMG in measuring the conditions of MFs.Methodology/Principal FindingsFive electronic databases were extensively searched for potentially eligible studies published between 2003 and 2012. Two authors independently assessed selected articles using an MS-Word based form created for this review. Several domains (name of muscle, study type, sensor type, subject's types, muscle contraction, measured parameters, frequency range, hardware and software, signal processing and statistical analysis, results, applications, authors' conclusions and recommendations for future work) were extracted for further analysis. From a total of 2184 citations 119 were selected for full-text evaluation and 36 studies of MFs were identified. The systematic results find sufficient evidence that MMG may be used for assessing muscle fatigue, strength, and balance. This review also provides reason to believe that MMG may be used to examine muscle actions during movements and for monitoring muscle activities under various types of exercise paradigms.Conclusions/SignificanceOverall judging from the increasing number of articles in recent years, this review reports sufficient evidence that MMG is increasingly being used in different aspects of MF. Thus, MMG may be applied as a useful tool to examine diverse conditions of muscle activity. However, the existing studies which examined MMG for MFs were confined to a small sample size of healthy population. Therefore, future work is needed to investigate MMG, in examining MFs between a sufficient number of healthy subjects and neuromuscular patients.
