Muscle stiffness of the smaller muscles of the body specifically the thenar eminence and perineal muscles can be reliably and objectively measured using the “MyotonPRO” in women aged 18–50 years (M.J.Davidson, et al. 2016). The demonstrated good to very good interrater and intrarater reliability in measuring muscle stiffness using the “MyotonPRO” means that the device could be used as an objective reference standard in developing a digital palpation scale or as a pre- or post-intervention measurement device. Future research to develop a digital palpation scale would facilitate the accurate diagnosis of increased, reduced, or normal muscle stiffness, and it would assist with the clinical management of perineal muscle, and potentially levator ani muscle, dysfunction. Levator ani muscle dysfunction is implicated in many pelvic floor disorders in women, so the potential significance of this pilot work is substantial.
Our studies on Parkinson’s patients indicated high sensitivity of myometry to the mechanical properties of muscle changes related to an occurrence of parkinsonian rigidity. These studies showed, that myometry is a sufficiently sensitive method to: (i) differentiate the resting muscle belly (Marusiak et al. 2010, 2011) and tendon stiffness (Marusiak et al. 2011) between PD patients and healthy controls, as well as to reveal changes in resting muscle stiffness as an effect of: (ii) anti-parkinsonian medication (Marusiak et al. 2012) and physical exercise training cycle (Marusiak et al. 2015), applied in PD individuals. Besides the scientific merit of our findings, these studies also have clinical relevance especially for monitoring of therapy effectiveness in PD. However, future multimodal studies with simultaneous application of myometry with neurophysiological (EEG, EMG) and neuroimaging methods (fMRI, PET) are needed on a greater PD patients’ sample, and with broader severity range of parkinsonian rigidity symptom, to understand the meaning of myometric parameters outcomes for clinical application.
“MyotonPRO” enables us to detect even minor changes in muscle stiffness (R.Marvulli, G.Ianieri et al. 2016). This provides with invaluable information necessary to determine the optimum dosage and time-interval between pharmacological treatments, which is beneficial for patients with neurological disorders (e.g. reduces antibodies) and for the social pharmaco-economics.

An accurate instrument is needed to objectively quantify the tension and stiffness of paravertebral myofascial tissue, particularly in the lumbar region. The “MyotonPRO” is a practical instrument which accurately quantifies myofascial tone, dynamic stiffness and other bio-mechanical and visco-elastic parameters. Our clinical studies have shown that the measurement results are repeatable on an individual subject. However, further research is needed to determine the depth of tissues which are providing the measured responses. Once the measurement results can be correctly translated to the varied physiological myofascial properties, it can be more widely applied in clinical usage. The results provided by “Myoton” can be used as an essential indicator of normal vs altered clinical conditions as well as a guide in patient monitoring and therapy.

“MyotonPRO” is a unique, quick and easy to use research tool. In my clinical practice it has proven remarkably cost-effective and efficient. The role of this instrument is very important for the clinical evaluation of treatment efficacy. I have been successfully able to study and validate the effects of different interventions, PRE, POST and over-time.
Based on objective outcomes it has been possible to develop and improve new Myofascial techniques, as it is imperative to know whether a treatment causes an expected result.
We have conducted a number of meaningful studies in collaboration with several universities (C.M.Gordon, et al 2016).
In addition, we have used “MyotonPRO” in 15 pilot studies were the findings inspired us to develop a completely new myofascial self-help tool called the “Fascia-Releazer”. During the research we obtained knowledge and understanding about the dynamic and magnitude of changes in the myo-fascial tissues being treated.

I foresee Myoton technology as an important diagnostic solution in the wide range of clinical applications, in sports as well as in space, where people live and work under extreme conditions on the ISS – International Space Station.
“MyotonPRO” is probably the best known research tool for measuring muscle tone.
