Shear wave elastography is a new noninvasive tool for the analysis of the biomechanical properties of the muscles in healthy and pathological conditions. Shear wave elastography is currently considered as a promising real-time visualization tool for quantifying explicitly the mechanical properties of soft tissues in sports medicine including muscle strain injury (MSI). This chapter shows utilizing diagnostic tools of magnetic resonance imaging, B mode ultrasound (US), and shear wave elastography in both acute and chronic phases. Also, the proposal for this chapter is to indicate the possibility of utilizing shear wave elastography for musculoskeletal injury, not only properties of the muscle but also fascial tissues. It introduces the relationship between previous muscle strain injury and local soft tissue stiffness, and we assessed the mechanical properties of soft tissues from a clinical perspective.

“…Therefore, it could be used to diagnose and monitor musculoskeletal injuries [67]. Indeed, Yoshida et al [71] successfully used SWE for objectifying the healing process of a gastrocnemius muscle injury. It seems that SWE could be used as a quantitative measurement of the changes in stiffness during the muscle healing process (with the healthy side as reference).…”

Return to Play After a Hamstring Strain Injury: It is Time to Consider Natural Healing

et al. 2021

Return to play (RTP) criteria after hamstring strain injuries (HSIs) help clinicians in deciding whether an athlete is ready to safely resume previous sport activities. Today, functional and sport-specific training tests are the gold standard in the decision-making process. These criteria lead to an average RTP time between 11 and 25 days after a grade 1 or 2 HSI. However, the high re-injury rates indicate a possible inadequacy of the current RTP criteria. A possible explanation for this could be the neglect of biological healing time. The present review shows that studies indicating time as a possible factor within the RTP-decision are very scarce. However, studies on biological muscle healing showed immature scar tissue and incomplete muscle healing at the average moment of RTP. Twenty-five percent of the re-injuries occur in the first week after RTP and at the exact same location as the index injury. This review supports the statement that functional recovery precedes the biological healing of the muscle. Based on basic science studies on biological muscle healing, we recommend a minimum period of 4 weeks before RTP after a grade 1 or 2 HSI. In conclusion, we advise a comprehensive RTP functional test battery with respect for the natural healing process. Before deciding RTP readiness, clinicians should reflect whether or not it is biologically possible for the injured tissue to have regained enough strength to withstand the sport-specific forces. In an attempt to reduce the detrimental injury-reinjury cycle, it is time to start considering (biological healing) time.

A Method to Characterize Skeletal Muscle Contractile Properties Using a Wearable Ultrasonic Sensor

Skeletal muscle monitoring provides valuable information about the muscle contractile properties which could be useful in various clinical applications. A wearable ultrasonic sensor (WUS) was constructed using a 110 µm thick polyvinylidene fluoride polymer piezoelectric film to perform a continuous hands-free muscle monitoring. The lightweight and flexible properties of WUS enables the stable attachment to the skin surface without affecting the tissue motion of interest, which results in reduced motion artifacts. In order to perform reliable estimation of tissue thicknesses by the WUS in an ultrasonic pulse echo mode, the accuracy of selected signal analysis techniques was evaluated using a laser displacement measurement result as a reference. Then, a mechanical simulation experiment is conducted to evaluate the accuracy and repeatability of the WUS measurement system. In addition, the effects of moving averaging on the signal-to-noise ratio of the ultrasonic signals and the estimation accuracy of the tissue thickness were investigated. In order to demonstrate the feasibility of the proposed ultrasound technique for in-vivo measurements, continuous monitoring of the lateral head of triceps muscle of three healthy male subjects were monitored using the WUS. The tissue thickness changes due to the evoked muscle contraction by an electromyostimulation (EMS) at various pulse repetition frequencies were monitored. I thank Mr. Alex Proctor for assisting and technical supporting me in designing the mechanical phantom. I would like to thank my friends, Mr. Dipayan Mitra, Mr. Sean Trudel, and Mr. Shanmugaraja K.V who helped me in all possible ways. I would also like to thank Carleton University for supporting the work. I would like to express my gratitude towards my parents and my brother for their unwavering support.
