TENSIOMYOGRAPHY
QUANTIFYING MUSCLE FUNCTION
TENSIOMYOGRAPHY (TMG)
A BRIEF INTRODUCTION:
Tensiomyography (shortly TMG) is an evidence-based method which precisely measures the speed of muscle contraction and muscle stiffness. It’s used in performance, sport medicine and research.
Individualize training plans.
-
Profiling athletes
-
Injury prevention
-
Detection of weak links in kinetic chains
-
Monitor readiness
TMG provides the athlete’s muscle profile, so that you get the information which muscle needs to be faster, stronger or if you need to relax a particular muscle.
Coaches have the challenging need for boosting performance and screening risks. TMG supports coaches with a detailed and quantitative insight into athletes.
PERFORMANCE
SPORTS MEDICINE
Objectively evaluate functional muscle disorders.
-
Return to play decisions (not predictions)
-
Managing risks
-
Screening and assessment
-
Rehabilitation monitoring
Medical professionals have the challenging need for screening risks, reducing non-contact injuries, and ensuring that the return to play doesn't result in re-injury. TMG can solve these three problems in a fast, precise and objective manner.
Support for visible scientific publications.
-
Acute and chronic muscle changes diagnostics
-
Non – invasive determination of muscle composition
-
Detection of local muscle fatigue
Tensiomyography is being used by some of the most prestigious research institutions in the world, helping them detect acute or chronic changes in the muscle’s ability to contract/relax. Novelty, relevancy and credibility of the information presented in a particular publication can significantly affect its impact. Tensiomyography has been used in more than 100 scientific papers.
RESEARCH
TENSIOMYOGRAPHY IN DETAILS:
Tensiomyography is a rapidly evolving technology that is non-invasive, practical, fast and reliable. It helps to quantify rehabilitation or training progress and consequently provides an objective assessment of the efficiency of a certain treatment protocol. The specific muscle contraction properties that it measures are important parameters for medical and performance staff, which are looking for a real insight into an individual muscle’s status.
The strengths of TMG S2 are its simplicity, flexibility and compatibility with other methods and applications on or off the field. Athletes can be profiled, monitored and guided through the rehabilitation or training in a matter of minutes.
Unlike static medical imaging, TMG S2 reveals the true functional ability of muscles without excessive costs, time or travel.
Assessments are painless, require no effort from the athlete and can be done even during the acute phases of injury to obtain essential, clear and objective benchmarks.
Researchers as well as sports medicine and performance professionals all have a common need for relevant and objective information so that decisions can be made faster and be more informed. TMG S2 provides this in an efficient, fast and simple way. Furthermore, the informative value of the data about muscle function cannot be replicated by any other modality.
HOW DOES THE TMG
MEASUREMENT
PROTOCOL
LOOK LIKE?
Tensiomyography (TMG) is used for monitoring radial muscle belly displacement under isometric conditions. The displacement sensor is positioned perpendicularly to the tangential plane on the largest area above the muscle belly. The muscle belly displacement (enlargement) during contraction is observed and monitored.
Experimental setup used to evoke and measure the biceps brachii (BB) isometric twitch contraction responses. The TMG sensor measures muscle radial displacement during twitch contractions induced by short electrical stimuli. The stimulating electrodes are placed directly onto the skin.
Muscle contraction is elicited by single-twitch electrical stimuli. Two self-adhesive electrodes are placed around the TMG sensor. The anode is placed distally and the cathode proximally, 20-50 mm from the measuring point. Bipolar electrical stimulation consisted of a single DC pulse of 1 ms in duration.

TMG PARAMETERS
Delay time (Td) as a time between the electrical impulse and 10% of the contraction
Contraction time (Tc) as a time between 10% and 90% of the contraction
Sustain time (Ts) as a time between 50% of the contraction and 50% of the relaxation
Relaxation time (Tr) as a time between 90% and 50% of the relaxation
Displacement (Dm) as maximal amplitude of the muscle contraction
Fig. 2.
The parameters that were measured with the TMG signal:
Dm – maximum amplitude (displacement),
td – initial delay time,
tc – contraction time,
ts – sustained contraction time and
tr – half relaxation time.
