  • A limitation for device use is the cost and accessibility. Foam rollers and basic massage tools are cheap and widely available. In contrast, high-quality massage guns can be expensive, and shockwave machines are very costly and thus limited to clinics with those resources. Additionally, certain devices require expertise to use correctly (Kerautret et al., 2020). Shockwave requires knowledge of proper dosages and locations. Massage guns also come with contraindications such as not using over nerves, bony areas, or sensitive tissues (Ferreira et al., 2023). Thus, training and guidelines are important to prevent misuse. Generally, with reasonable use, these devices are safe. Device-mediated interventions further expand the delivery of fascial loading through self-applied and technology-assisted modalities. These approaches improve accessibility and support integration of fascial release within broader rehabilitation strategies.

    Effects of Lower-Leg Fascial Flossing on Flexibility and Performance in Collegiate Distance Runners: Ultrasound Evaluation of Fascial Gliding · 2026 · DOI

  • The cross-correlation coefficient ultrasound analysis demonstrated enhanced myofascial gliding in the flossed leg, but the study did not examine whether improved fascial gliding correlates with reduced injury risk or specific running economy metrics in distance runners. Future research should longitudinally track fascial gliding changes against injury incidence and running economy in collegiate distance runners.

    Mechanomyography as a novel marker of nerve dysfunction and recovery in chronic entrapment neuropathy · 2026 · DOI

  • While stimulus threshold appears to be a useful quantitative metric of nerve dysfunction, there was not a statistically significant difference in the amplitude of muscle acceleration between compressed and non-compressed sides. Since increases in acceleration amplitude were previously reported following nerve root decompression in one clinical study (24), this metric was evaluated as a potential additional biomarker. There are several possible explanations for this negative result. First, compression neuropathy has been shown to be a primarily demyelinating process, independent of axonal damage in its initial stages (42, 43). Demyelination leads to exposure of the internodal membrane and an increase in the stimulation required for excitation (48), which explains the increase in MMG-st. However, MMG amplitude should be most sensitive to axonal loss, as this would decrease the number of motor units activated and decrease muscle acceleration. From a physiologic perspective, it is therefore reasonable to expect MMG-st to be more sensitive than acceleration amplitude for this nerve entrapment model. Second, variations in positioning and attachment of the accelerometer sensor on the rat may have introduced variability sufficient to obscure modest amplitude differences. The accelerometer sensor was around the same size as the rat hindlimb, limiting the precision of consistent placement in a way that could be less problematic in human patients. small but statistically Additionally, significant baseline differences in MMG-st and CMAP latency were observed between sides prior to any intervention. The directions are contradictory: MMG-st was slightly lower for the experimental nerves which would later undergo compression (suggesting a healthier nerve), while CMAP latency was higher (suggesting a less healthy nerve). The latency difference may have a systematic explanation related to temperature-dependent conduction velocity. We performed all procedures on the control side first to minimize the interval between electrophysiology studies on both sides, as the silicone tube placement/removal on the experimental side was the most this ordering may have time-consuming element. However, introduced a systematic bias, as core temperature likely decreased between measurements. Assuming a 3 C drop (49), 40 mm nerve length, 50 m/s baseline conduction velocity, and a temperature C (50), the expected latency increase is coefficient of 2.8 m/s/ 0.16 ms, essentially equal to the observed baseline difference. However, temperature does not explain the lower MMG-st on the experimental side, as decreasing temperature should increase stimulation threshold (51). The baseline difference in MMG-st most likely reflected natural side-to-side variability that reached marginal significance (p = 0.045) given the large pooled sample. Even if the difference was due to some unknown systematic bias, this would mean that the effect size observed in MMG-st following compression would be an overly conservative estimate. Importantly, post-compression changes in both measures far exceed these small baseline differences, and they are unlikely to meaningfully affect the primary conclusions. ◦ ◦ A limitation of the MMG devices tested was inability to measure latency, which would be expected to be increased due to nerve compression. Our device operated at a sampling rate of 200 Hz, corresponding to a sampling period of 5 ms. Over such a short propagation distance (∼50 mm) in the rat model, this did not provide enough temporal resolution to monitor increased latency due to compression. This limitation could be resolved in future work by upgrading the hardware and processing pipeline to allow for increased sampling frequency, and this would be less problematic in humans due to longer nerve lengths. Aspects of the experimental design could be improved for future studies. The intention of testing varying entrapment duration was to analyze worsening severity over time (39). While the 2-month cohort did appear to be less severely affected based on MMG and histomorphometry, from 3 months onward there was no clear worsening. There were 4 animals in the 6-month cohort which experienced severe nerve compression; while this may have been exacerbated by the long duration, we believe this was primarily due to a deviation from protocol in which the sutures around the silicone tube were overtightened. This does suggest an alternative future approach for testing varying entrapment severity by using tubes of varying internal diameter.

  • The included studies had significant heterogeneity in therapeutic protocols, intervention duration, patient populations, and outcome assessment methods.
